Abstract:
Although MS Windows (in its various versions) is at present the most popular OS (Operating System) in personal computers, after years of consecutive improvements there are still various issues which need to be improved, which include for example issues of efficiency, comfort, and/or reliability. The present invention tries to solve the above problems in new ways that include considerable improvements over the prior art. Preferably the system allows for example a “Reset” function, which means that preferably an Image of the state of the OS (including all loaded software) is saved immediately after a successful boot on the disk or other non-volatile memory and is preferably automatically updated when new drivers and/or software that change the state after a boot are added, so that if the system gets stuck it can be instantly restarted as if it has been rebooted. Other features include for example solving the problem that the focus can be grabbed while the user is typing something, allowing the user to easily define or increase or decrease the priority of various processes or open windows, a powerful undo feature that can include preferably even any changes to the hard disk, improved undo features in word processing, improved file comparison features, being able for example to track changes retroactively, improved backup features, and many additional improvements. The application covers also improvements that are related for example to Word processing (since for example in Microsoft Windows, Word behaves like an integral part of the system) and things that are related to the user&#39;s Internet surfing experience, including for example improved search experience (This is important since for example in Microsoft Windows, Internet Explorer is practically an integral part of the OS). The invention deals also with some preferable improvements in the performance of the hard disk and also with some other smart computerized devices.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to operating systems, and more specifically to a System and method for improving the efficiency, comfort, and/or reliability in Operating Systems, such as for example Microsoft Windows. This can include for example also things that are related for example to Word processing (since for example in Microsoft Windows, Word behaves like an integral part of the system) and things that are related to the user&#39;s Internet surfing experience (This is important since for example in Microsoft Windows, Internet Explorer is practically an integral part of the OS). The invention deals also with some preferable improvements in the performance of the hard disk. 
         [0003]    2. Background 
         [0004]    Although MS Windows (in its various versions) is at present the most popular OS (Operating System) in personal computers, after years of consecutive improvements there are still various issues which need to be improved, which include for example issues of efficiency, comfort, and/or reliability. In the area of efficiency, one of the things that still need improvement is the time it takes the system to boot. For example if windows 98 gets stuck, the user might have to re-boot the system, a process which can take up to a few minutes, especially if there are many programs in the start-up folder and/or if the system starts to scan the disks (If the user does not interrupt the disk scan). Although Windows Me and XP for example include a Hibernate function, it does not help much if the system gets stuck, since Hibernate is mainly useful if the user requests the system on his/her own initiative to “go to sleep” for fast awakening afterwards. This is accomplished typically by saving an Image of the current state of the computer&#39;s memory on the disk when the user issues the “Hibernate” command, and reloading it quickly when the user requests “wake-up”. US Patent application 20020078338 filed on Dec. 15, 2000 by IBM, describes an improvement in which the Image is saved automatically immediately after the normal boot sequence has finished, so that, during the next boot, the boot can be automatically set to much faster if there is an Image of the state of the computer and the OS at the end of the last boot. However, this still does not solve the problem completely, since for example if Scandisk is needed, it can still take considerable time, such as for example a number of minutes or even more, and also for example some peripheral devices checks and/or initializations might still be needed and can take for example even up to a minute even during the “instant” boot. The IBM patent does not even mention the problem of the peripheral devices or drivers. Issues of convenience can include for example the fact that various things happen automatically in Windows without asking the user&#39;s permission—for example one thing that can aggravate users is the ability of other programs to suddenly snatch the focus from the current Window. If this happens for example while the user is trying to type something, it can be very irritating, especially if it&#39;s for example some pop-up commercial advertisement in a browser window while the user is surfing the web and is trying for example to type some data in a form input line or in the URL line. Another convenience issue is for example the problem that when installing a new version of Windows over an existing system, typically the user has a choice of either overwriting the current system, in which case the desktop will remain the same as much as possible (but the user will have to give up the option of still booting the old system), or to install it in a new partition, in which case the user typically has to install almost everything again from scratch. An example of a reliability issue is the fact that making errors, such as for example launching a program which contains a virus or a malicious code, or installing a program which accidentally causes damage for example to the Windows registry or to various directories, can be very difficult to correct. Although, for example, starting from windows ME, there is an option to undo the last installation, it is typically limited to only very specific types of changes in the system, such as for example changes in the registry, but cannot undo other changes, such as for example ruining other directories or files. 
         [0005]    Clearly it would be desirable to have improved versions of Windows or of similar Operating Systems, where such problems are solved. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention tries to solve the above problems in new ways that include considerable improvements over the prior art. 
         [0007]    Regarding the boot problem, preferably the system allows a “Reset” function which means that preferably an Image of the state of the OS (including all loaded software) is saved immediately after a successful boot on the disk and/or on other non-volatile memory and is preferably automatically updated when new drivers and/or software that changes the state after a boot is added. Another possible variation is that more than one Image can be saved, so that for example if something goes wrong after updating the Image, the system can preferably go back for example to the previous Image. Whenever the system gets stuck (and/or for example if the user simply wants to clear the computer&#39;s memory and go back to a state like after a normal boot), preferably the user is able for example to press some special button or some key or keys on the keyboard and/or for example click on some icon or menu item or link (however a hardware key at least as one of the available activation options is important since otherwise the user might not be able to activate it for example if the system got stuck for some reason) in a way that causes the computer&#39;s memory to instantly Reset from the saved Image, without a need to go through a boot sequence at all. The special button or key (or icon or menu item, etc.) is preferably sensed either by hardware or by some process which preferably runs below the Operating system and thus in not affected even when the system becomes stuck. In addition, preferably any cut &amp; paste buffers are preferably automatically saved also on the disk and/or other non-volatile memory preferably whenever they are created, so that they can be immediately available on the next boot or after the next Reset. Similarly, preferably any currently edited files or windows are preferably automatically saved on the disk and/or on other non-volatile memory preferably after sufficient minimal changes have accumulated (such as for example after at least 10 new characters, or any other convenient number, have been added or changed) or every short while (for example every 30 seconds), so that they can be immediately available on the next boot or after the next Reset. Preferably, during or after a fast-boot or a Reset that uses the memory Image (and/or even during or after a normal boot), if the FAT of the disks needs to be checked, preferably it is done in the background and without significantly slowing down the disk or the CPU, after the user can already start working, since waiting for scandisk to finish can take several minutes and can be very aggravating to most users. Preferably the system runs a minimal scandisk in advance at most only on the area where the image itself is stored or does that only if there is for example some CRC problem when trying to get the image, since only that area might have to be scanned before the boot or Reset if there is a problem, and the rest of the scandisk is preferably done in the background after the boot without disturbing the user. Another problem is that even without scandisk usually after the system boots typically various start-up applications keep loading (for example both in Windows 98 and in Windows XP) and during this time the user can almost do nothing since the start-up applications take control most of the time. So preferably this is improved so that after the boot (i.e. preferably for example in the first few minutes after the boot) preferably the OS automatically gives higher priority to actions taken by the user (such as for example clicking with the mouse on something and/or typing text). This can be done preferably for example by increasing the frequency of sampling for user input and/or increasing the priority to tasks which the user is interacting with, so that the user can preferably start working preferably normally immediately without having to wait for the start-up programs to load. Preferably this works of course in combination for example with the feature described elsewhere in this application—of avoiding snatching away of the focus while the user is for example typing something or for example while the user is performing some activity for example with the mouse—such as for example marking a section. However, preferably the user can also mark for example some programs (i.e. one or more) in the startup menu to have higher priority so that they are loaded first, such as for example the firewall or for example the DirectCD application (for example by moving them or for example changing a value or flag associated with them), so that for example the firewall will be fully loaded before the user connects to the Internet and the DirectCD will be loaded before the user tries to access the writeable CD, and/or the OS monitors automatically what the user normally does and/or knows for example which program is the firewall and gives it automatically higher priority to load earlier (Preferably the OS knows this for example by using a convention of type indicators for various applications and/or for example by monitoring their behavior, such as for example which functions or drivers they hook, etc). Another problem is that for example in Windows XP many times the user clicks on some application (for example a web browser such as Opera or Firefox) in order to activate (start it running) it but it takes 10 or 20 seconds or more till the user sees that it indeed opened, which can be very annoying and also the user is not sure in such cases if his/her click was accepted and might click several times and then several windows might open together after the delay. So preferably this is improved so that the newly clicked application gets preferably higher or much higher priority for loading than other already running applications since if the user just clicked on it then obviously it is at the focus of his/her attention and he/she expects it to open immediately, and/or if there is some problem for example to open it fast enough then preferably at least some window or message preferably appears preferably instantly and preferably informs the user that the OS is trying to open the specific application but there is a problem and preferably the problem is described shortly or at least named and preferably the OS shows an automatic estimate of how much time it will take till the application window appears. Another possible variation is that for example when the system tells the user during boot that unless he/she presses some key a scandisk will start in N seconds (as is done for example in Windows XP), preferably the system also gives the user an option for example to press a key that starts the disk scan immediately, thus saving an unnecessary wait of for example additional 10 seconds each time. Another problem is that for example in Windows XP, if the user did not click on something to skip the scandisk during boot, he/she can not stop it once it started. So preferably this is improved so that even after the scandisk started the user can for example click for example on Esc or some other key or click with the mouse on something and stop the scandisk immediately. Another problem is that if the user doesn&#39;t watch closely as this scandisk-during-boot progresses, he/she has no way if knowing if and what error were found and/or corrected because the OS does not keep a record. So preferably this is improved so that preferably the scandisk (or similar disk-checking application) during boot and/or also when activated normally after boot, preferably automatically leaves a log of what errors were found and what was done so that the user can know for example which files are now truncated because of errors even if he/she did not attend during the boot (Preferably there are multiple such logs or for example the log is cumulative, for example with dates and times, so that the user can see also what happened at earlier Scandisks). Another possible variation is that this automatic log automatically contains also at least some undo information so that the user can for example request automatic undo of the recent changes or some of them. Another possible variation is that the OS keeps for example also a table of all the files that have been truncated for example due to various scandisk operations, so that the user can know exactly which files need to be restored for example from backup or installed again (preferably this is marked also for example in the directory entry of each such file, so that for example files that were truncated for example by scandisk or by similar programs are preferably automatically marked as truncated files for example when the user sees them in the explorer or in the Save or Open dialogue box or when typing “dir” in a CMD or DOS window, so that the user can know that there is a problem with such files, and for example if the user fixes the file the mark that the file was truncated is preferably automatically removed and preferably when removed this updates automatically also for example the central table of truncated files. Another possible variation is that preferably when there are problems found during the scandisk during the boot (and/or for example also when the user runs scandisk for example normally after the boot) preferably the system sounds an audible indication, so that the user can pay attention if he/she was concentrating on something else, and/or preferably the OS also preferably provides for example a vertical lever which the user can use to go back in the scroll-lines on the screen, and/or preferably if errors were found the system preferably waits for user input at the end of the scandisk before continuing with the boot, or for example after the boot is finished a message is preferably displayed about the errors found during the scandisk during boot, preferably together with a link to the log file so that the user can preferably click the link in order to access directly the log file that details the problems that were found and fixed during the scandisk. Another problem is that for example sometimes the computer gets stuck during the boot temporarily or indefinitely and the moving horizontal squares (for example in Windows XP) stop moving, and then the user does not know if it&#39;s a temporary problem or the computer has become stuck and need to be rebooted. So preferably if the squares stop moving preferably this is accompanied for example by some additional message or information which indicates to the user what is happening and/or for example there are at least other element or elements which keep moving as long as the boot is still proceeding, so that for example if they also stop then the user known that indeed the computer is stuck and has to be rebooted. Another possible variation is that preferably a copy of the installation files of the OS are preferably constantly also on one of the directories of the hard disk and/or for example at least important installed system files and/or also other important files are preferably automatically backed up in at least one more place (preferably on another dive), and preferably if the scandisk for example during the boot for example finds that various system files got screwed up, then preferably it can also automatically restore them from the backup, so that preferably they can be restored for example even before the boot continues. Another problem is that for example in Windows this dialogue about scandisk during the boot is presented at a refresh rate of 60 Hertz, which can be very painful to the eyes, and also for example the boot selector in Windows Vista is in 60 Hertz, and also the boot logo for example in Windows XP and Vista is presented at 60 Hz, which probably occurs because Windows does not load yet the appropriate display driver. So preferably this is improved so that preferably any text or images displayed during the boot are presented for example at the refresh rate which the user last used before restarting the computer, or at least for example at 75 Hz or more or for example 80 Hz or 85 Hz or more (this is preferably done not only in normal reboots but also for example when installing a new OS—for example Vista, at least if it is installed for example from an exiting OS installation, so that preferably even during the installation preferably the higher refresh rate is used even after additional boots and even during the installation—preferably by saving this information and/or any additional relevant parameters about the existing display parameters or the details of the current display driver in a file which is then read also after the subsequent boots). This is preferably done for example by keeping the last used normal refresh rate and preferably also the monitor plug and play identifier and preferably also the last used resolution (which were used during the last normal Windows session after the boot) in variables in a file which can be read during the boot so that, at least if the monitor has not been changed, the OS can be sure that the monitor is able to display this refresh rate (for this preferably at least the parts of the driver that talk to the plug and play element on the monitor are loaded at the beginning of the boot) and thus can preferably use it starting even from the boot selector. Preferably the OS uses at this early stage for example basic display drivers of its own (in order to avoid the risk of malware in drivers) and preferably these drivers can work in a ring above ring 0 and preferably the OS can also automatically for example switch them after the boot finished and replace them for example with the more exact or more complete drivers which are normally used after the boot. Another possible variation is that, since typically during the boot the resolution used is relatively low anyway (for example 640×480), preferably the OS can assume that any normal monitor is capable of using at least a refresh rate of 85 Hz at this resolution or can protect itself by switching to a lower refresh rate automatically if it can&#39;t. Another possible variation is that the normal display driver (i.e. the same driver that is already installed to work after the boot) is preferably loaded in advance at the beginning of the boot (preferably together with the parameters that were used in the last normal work before the restart), before the first boot logo even appears, and so preferably not only the correct refresh rate can be safely used at this stage but preferably also the higher resolution which the user is used to. If more than one OS is available, preferably the last known refresh rate and the plug and play identifier of the monitor are available in a standard place for to all the OSs, or at least available to the boot selector, so that even the boot selector itself can be displayed that way, unless for example it is in text mode like in windows XP, since the text mode at 70 Hz is readable without problems anyway. Of course various combinations of the above solutions can also be used. Another possible variation is that for example the monitors themselves and/or for example display cards are improved so that preferably they automatically ignore or can be programmed to ignore for example commands for working at refresh rates for example below 85 Hz or for example below 75 HZ (unless for example at the high resolution used the display card or the monitor is able to work only at a lower Hz, in which case preferably it uses the next best available option), so that even if the OS tells the monitor or the display card for example to work at 60 HZ, preferably the display card or the monitor will ignore the command and work for example at 75 Hz or 85 Hz or more (at least until the user changes this setting). This should be no problem in terms of usage because it is very difficult to conceive of a situation where a user would prefer to work at 60 Hz instead of for example 85 Hz. Another problem is that if for example there is more than one bootable OS installed on the same computer and the user for example switches between two monitors on the two monitor connectors on display cards that support dual monitors, or for example disconnects one of the monitors and then reconnects it and disconnects the other, or switches monitor connectors for any other reason, it will be updated properly on the current OS but other OSs which for example expect the monitor on the other monitor connector will show a blank screen. So preferably this is improved so that if the OS and/or for example the display card driver or for example some other relevant application discovers that the monitor is now connected to the other connector and there is no monitor on the original connector, preferably the display driver automatically switches to the connected connector and preferably also displays a notice about it to the user (this is no problem since virtually all monitors today are plug-and-play monitors, and even for example with a non-plug and-play monitor its presence or absence on a connector can be easily sensed electronically). (Preferably, as explained elsewhere in this application, preferably for example the display card or the OS preferably senses also if the monitor is turned on and takes this into account). This is also important for example in case the user has to restore the system into an earlier checkpoint in which the monitor was connected to the other connector. Similarly for example if the user switched between the two monitors and the OS discovers that their positions on the connectors are now reversed, preferably the OS and/or for example the display driver (or for example other application or service which is in charge of this) preferably automatically switches also the definitions between the two monitors (such as for example resolution, refresh rate, color corrections, video overlay definitions, etc.) so that the user does not have to do this manually. Another possible variation is that preferably when the user creates a System checkpoint preferably the OS allows the user to choose preferably each time if to create a full copy of the relevant system files (such as for example the Registry_Machine and Registry_user files in Windows XP) or just a copy of the incremental changes, for example by asking the user automatically each time or for example providing two separate links for these options. Another possible variation is that the Scandisk (or similar software) is backed up by hardware, for example in a way similar to the hardware that supports automatic disk rollback, described below. Preferably this is done by using hard-disks or other non-volatile memory wherein a special area or areas is dedicated for FAT information, and preferably independent head or heads or other access means are used for read and write in those areas (so that for example one possible variation is that for example if the hard disk comes with internal flash memory, preferably part of that flash is preferably used for example for storing the FAT at least temporarily, but this means that the actual FAT on the disk can be written to for example after many minutes, instead of the normal cache of a few seconds, especially for example when copying a large number of files, so that the heads do not have to jump back and forth to update the FAT all the time, without worrying about power interruptions, and in this case preferably after each boot preferably the hard disk checks first of all is there are any updates in the FAT according to the flash memory that need to be updated in the hard disk itself. This has the further advantage that any reading or writing of files can become faster even if they are fragmented, since less movements of the heads are needed to access the FAT area each time some jump is needed (Of course the FAT can be also for example loaded into RAM or into cache memory for reading, but due to safety reasons changes to the FAT have to written to the hard-disk or other non-volatile media as soon as possible, and that is why these improvements are very important). Since each disk can have more than one partition, preferably the FAT areas of all partitions are kept in the same special area or areas. Preferably these areas are also guarded better in terms of security, so that for example any write-access to them is monitored more closely. If more than one set of heads is used (i.e. preferably more than one independent arm, which typically access multiple plates), this can also be used for example also for creating more efficient defragmentation, so that for example one of the independent set of heads can be used for defrag while the user is working normally with another set of heads, thus preferably not slowing down at all the performance while performing also defrag, and/or for example when the user is away or working on something that does not require intensive disk accessing, (such as for example when working on the word processor), preferably for example two (or more) independent sets of heads can work simultaneously in cooperation on defragmentation, thus saving the need for example to jump back and forth between two places when moving a file. Another possible variation is that for example, preferably at least as one of the user-choosable options, (preferably also in normal disks with only one head or one set of heads) the system can preferably activate automatic defrag for example mainly or only on the files and/or directories which the user uses most often (preferably by running and keeping automatically such statistics) and/or for example on the free space, so that for example no or little time is wasted on defragmenting files which are only rarely or very rarely used, and/or for example their defragmentation is preferably automatically set for lower priority so that they are defragemented for example only if and when there is sufficient free time to work on it in the background and preferably only after the higher priority defragmentation of that media has been completed. Of course the Image and/or any other saved data can be kept also, in addition or instead, on any non-volatile type of memory, such as for example MRAM (Magnetic RAM), which will become available in a few years, 3d Nano-RAM chips, etc. In such cases, instead of separate or independent heads, for example separate or independent access channels or processors can be used. Another possible variation is that for example the hard disk has one or more separate heads which are used for example only for checking the media for errors and for example move automatically all the time or periodically once in a while to check this without interfering with the normal function of the hard disk. Another problem is that for example in Windows XP many times after a program has finished installing it requests the user to do a complete restart of the computer, which can take considerable time especially for example if the motherboard contains a RAID driver for some of the devices (typical for example in new motherboards which support for example both IDE and SATA), while in almost all cases logging-off and logging-on again into Windows would be quite sufficient and of course much faster. Full restart should normally be required only for example if a new hardware has been added (in most cases this requires turning off the power so a full restart happens anyway) or for example in some cases of rewriting the flash memory of some devices. So preferably by default either the OS automatically determines if a full restart is needed (for example according to the nature of the new installation), and then preferably the OS automatically performs just logoff and logon instead of a full restart whenever it can determine that this is sufficient, and/or for example standard installers are improved so that the software vendors can easily indicate (for example through some flag or flags) if logoff-logon is sufficient (for example even mark it as a set of automatic conditional rules, depending for example on various parameters, such as for example the OS version and/or various hardware parameters). Another possible variation is that preferably when the user himself/herself initiates a restart command (especially for example if no new software has been installed since the last boot and/or for example if the user has not recently inserted a bootable diskette or CD into one of the drives), preferably the OS automatically asks the user if he/she really wants a full reboot and, if not, preferably offers the user to automatically perform logoff-logon instead. Another possible variation is that at least for example the logon/logoff is added also to the normal Restart/Turnoff menu, so that for example instead of showing only 3 options (Standby, Turnoff and Restart) preferably the option of fast Logoff/Logon is also added. Another possible variation is that for example if the user connects new hardware while the computer is running, such as for example a different keyboard or a different mouse and/or other hardware, preferably the OS automatically detects the change in the hardware and preferably automatically updates the relevant drivers or drivers preferably without having to reboot the system. For this preferably the OS can use for example an additional abstraction layer for example between programs and device drivers so that for example there is a meta-driver layer with which the applications talk which intermediates between them and the actual drivers, and so if a driver has changed the OS for example preferably only has to update this layer without having to let the applications know about the change, and thus does not have to restart them. Another possible variation is that for example if the OS detects a new device (whether added while the OS is running or before the boot) and does not succeed to automatically find a sufficiently appropriate driver, preferably it tells the user (i.e. preferably automatically) also the specific hardware Id of the device (such as for example what type of device it is, the manufacturer and the model—which is no problem since the OS automatically reads this data from the hardware itself before starting to search for the driver), so that the user can know exactly for example what driver to try to download from the Internet. This is better than the prior art, in which Windows can for example tell the user that it is a display device or a sound device, but does not indicate the manufacturer and/or the exact model, and then the user might have to turn off the computer and open its case to check what is written on the card and then reboot, which is very inefficient. Another possible variation is that if the user is trying to install a device for example from a certain directory in a CD or DVD or other device and the system for example does not succeed to find an appropriate driver there or does not succeed to install it, preferably the user can for example use a Back arrow or icon to go back to the previous menu and for example choose a separate directory, instead of having to start again from the initial menu of updating the driver. Another possible variation is that when the user removes a device from the device manager preferably the OS offers the user also an option of marking the removed device so that the system will not rediscover it again automatically for example on the next boot for example until the user removes this mark. Another problem is that if the user for example wants to install another copy of the OS (for example Windows XP) on a separate partition and for example the original CD did not include service pack 2 and the user already installed service pack 2, the OS does not allow the installation while running, claiming that this is a lower version of the OS, and for example the OS makes it almost impossible to install for example Windows XP home if for example Windows XP Professional is already installed, even when booting from the CD for installation, even if the user wants to install it on another partition or for example another hard disk. So preferably this is improved so that if the new installation is on a separate partition the existing OS does not prevent the user from installing the other OS even if it is considered a downgrade (or for example at least unless the existing OS thinks that the new OS might screw up for example the boot selector), and/or for example if the new OS might screw up the boot selector (such as for example when installing Windows 98 on another partition if XP is already installed or for example installing XP if Vista is already installed), preferably at least if the user starts the installation when working in the more advanced OS, preferably the more advanced OS or for example a special application preferably automatically protects the boot elector of the more advanced OS for example by catching the attempts of the less advanced OS to install its own boot menu or boot selector for example at the beginning of the disk and redirecting it preferably to the appropriate place where the more advanced OS would normally put the boot menu or boot selector of the previous OS if it had existed before, so that preferably the next time the less advanced OS boots during the installation process it already boots preferably the same way that the less advanced OS normally boots in such system with Multiple installed OSs. Another possible variation is that if or example the less advanced OS needs to be installed by booting for example from its installation CD or DVD, preferably the existing OS can enable the user to simulate the boot without leaving the session in the existing OS, for example in a way similar to the way Microsoft&#39;s Virtual PC enables booting from a CD or DVD while installing a virtual OS, however, as explained above, if it is a real installation and not a virtual installation, preferably the OS being installed is redirected as described above Another possible variation is that preferably when installing the OS preferably the user is asked all the needed questions at the beginning and/or at the end of the installation—including for example the country settings, so that the installation can preferably really complete unattended (in other words, preferably all the questions that need to be asked are asked in advance and/or after the installation has finished, so that preferably the system does not stop for example in the middle of the installation to wait for some input, since the user might or example also be away, or for example except in cases of an unexpected problem during the installation which requires the user to decide what to do) (Of course even if the questions are asked at the end of the installation, typically at least some questions still need to be asked at the beginning anyway, such as for example under which partition or drive to install the OS). Another possible variation is that for example if the user is away and the system needs to ask something for example in the middle of the installation but it not critical, then preferably if no reply from the user is received after a certain time (such as for example 30 seconds or 2 minutes or other reasonable short interval) preferably the system continues the installation anyway in a way that enables postponing the question to later, for example by choosing in the mean time some default which can preferably by easily changed afterwards, or for example leaving some things open until later. Another possible variation is that for example during installation and/or during normal boot or when shutting down or logging off the system preferably displays automatically to the user at least some general feedback on what it is doing at each stage (such as for example the applications that are being loaded or closed or at least some general categories of activities), which is useful for making the time seem to flow faster and can also help the user to find for example problem areas that slow down the process). Another possible variation is that if for example the user installs a new installation of Windows on the same partition of a previously existing version of Windows, preferably common standard directories, such as for example “My Documents” and “Program Files” are automatically renamed or moved to be a subdirectory of some other directory—for example those of the original installation and/or those of the new installation, and preferably the OS in which the change is applied preferably automatically makes this the new default for example for Word documents or for new installations. Another possible variation is that these directories become virtual directories which appear for example to all applications as if they are in their normal places but are in practice for example a subdirectory of another directory or in some other place, as explained above. Another possible variation is that when the computer is in standby (hibernate) mode, even if the user for example turns the power off or even plugs the electrical wire out of the wall, preferably when the user returns the power, the system preferably still automatically returns from standby instead of normal boot. This is very easy since the saved image of the system is still the same, and the system can preferably identify from it and/or from some flag or other indication that it should be returning from hibernation, even if it had been for example completely powered off. This means that preferably when the user activates for example standby mode, preferably the system first creates the image and then can for example go into a mode where power is preferably used only or mainly for keeping the RAM refreshed (and for example the CPU, disk and screen are off), and so for example if the power remains on, when waking up the system preferably does not even have to restore itself from the image, and if power has been turned off then preferably the system automatically checks first to see if there is a recent image and then recovers from the image if possible, and only if there is a problem then it preferably automatically switches for example to normal boot. Another problem is that sometimes when the user requests for example to enter standby mode or to restart the computer or to logoff for example in Windows XP, the system says for example “Windows is shutting down” (for example when restarting or when shutting down) or “entering standby mode” but sometimes the system gets stuck indefinitely after this message and the user has to press reset. This typically happens if for example one or more services or drivers get stuck and do not terminate. So preferably in order to prevent this (for example at least if the system gets stuck or for example the process of closing for example services or drivers or processes for example takes longer than for example a certain threshold), the system preferably explicitly shows the user the list of services and/or drivers and/or other processes that still have to be closed and preferably indicates when each service or driver or process is closed, so that preferably the user can see where the system is stuck, and preferably the user can for example press a key which hastens the shut down in cases of processes or services that have not closed and/or the system for example automatically terminates (or for example freezes if needed in case of entering standby) such services or processes after a certain preferably short time limit for example even if it is stuck. In order to enable this preferably there is at least one or more processes below the OS which can automatically monitor such situations of getting stuck and preferably take the appropriate actions even if for example important parts of the OS have already shut down. Similarly for example while shutting down (for example for logoff or restart or shut down, as explained above) sometimes the OS displays for example a message about an application that is not responding and asks the user if to wait for it or close it immediately, and sometimes this is an application which the user has never seen before and/or might be suspicious, but apart for example from the title in the window the user does not even know what it is. So preferably in cases when such a message is displayed for example while shutting down and/or in other occasions, preferably the message also contains preferably for example automatically (or for example though a link which the user can click)—preferably at least minimal information about this application—such as for example name of publisher, if it is an internal part of the OS and/or for example since when it has been installed on the computer and/or for example from which file or directory it was installed and/or where the executable file of it resides and/or for example how long the process has been running in the current session and/or for example various data about its activity (for example based on automatic analysis of behaviors of various applications, as explained also elsewhere in this application), and/or for example clicking on it can open for example the Windows defender or similar application for example directly with the record of that application and/or for example this includes automatic comparison for example of the file size or fingerprint of this application compared for example to a database of known applications of the same name, as explained also elsewhere in this application. Another possible variation is that if for example the system still gets stuck for example while trying to shutdown or for example while trying to enter Standby mode, preferably at least the screen saver is automatically activated (preferably after the normal time without user activity for activating it has passed), since that would typically mean that user is not around and does not know that the system did not succeed to shut down or enter standby. This means of course that preferably even while shutting down or entering standby there is at least one or more active processes, for example below the OS and/or which remain open till the end, which preferably can still activate the screen saver as long as the system has not actually completed the shutdown or standby. Another possible variation is that the user can for example choose in the normal restart menu between normal standby/hibernate (with mirror image) and standby in which only the activity is turned off and power is at minimum, in which case preferably the system can instantly freeze any activity without having to wait for example for any services and/or drivers and/or applications to reach a certain state, and/or for example even when creating the image preferably the system can freeze anything preferably instantly without having to wait for any services and/or drivers and/or applications. Another possible variation is that preferably when the system creates the image for hibernation it can preferably save only the changes instead of the entire image, for example by separating in advance parts of the booted OS image that do not normally change between boots and keeping them at a separate place, and preferably when the system returns from hibernate the changing parts are preferably automatically added to the constant part to recreate the OS image. (Even if new drivers are installed for example, typically there will still be large parts of the booted OS image that would not change). Another possible variation is that preferably if the user chooses for example full reboot and/or even if he/she chooses just logoff and the system begins to close applications, preferably first of all only user applications are closed and not system processes and preferably the user can still for example press some key or click on some icon if he/she changes his/her mind in order to abort the reboot, and then for example the attempt to reboot is preferably aborted if it has not gone too far, and/or the system can automatically undo the process and even return the OS to the state it was before the reboot was requested (for example by keeping in one or more buffers also the state of the open files and/or windows and/or processes so that they can be restored automatically to their state before the reboot was requested). Another possible variation is that preferably one of the logoff-related options which the OS offers the user (for example in the normal logoff menu) is to logoff with immediate automatic logon again, which means that preferably as soon as the logoff is complete the system automatically log-on again to the same user. Another possible variation is that preferably one of the options for restart is fast-restart or fast-logoff (available preferably for example as one of the options when pressing Ctrl-Alt-Del and/or in the restart menu), which means that preferably the OS waits until the first few seconds (or other threshold) when there is no disk activity and then preferably instantly freezes all further disk activity and logs off or restarts immediately without waiting for any services or processes to close. This can also work for example with the instant Reset described elsewhere in this application, instead of the normal restart. Another possible variation is that preferably the installers are improved so that preferably even after the installation already starts (for example after the user finishes choosing all the options and presses “Next”), preferably the user can still for example use at least some scroll bar to view his/her previous choices, so that for example when installing Word 2007 the user can check again to make sure that he/she indeed chose not to remove previous versions of Word even while the installation is already proceeding, or for example the installer automatically lists a summary of the user&#39;s choices preferably at each stage, so that preferably even before pressing the last “Next” and preferably also after that the user can still see a summary of his/her choices (this variation is more preferable since this way the user can notice if there were any mistakes in his/her previous choices even before pressing the last “Next”). Another problem is that for example if the user installs more than one version of Word in the same OS installation (for example Word 2003 and Word 2007 or for example Word 2000 and Word 2007 or for example all 3 of them) then each time when opening for example a version of Word after last using the other version (for example by clicking on its icon on the desktop), the newly opened version automatically goes through some installation completion process, which can take even up to a few minutes (for example in case of Word 2007), and can be very annoying to the user, especially if he/she has to finish something urgently. (This apparently includes for example the newly opened version of Word registering itself again as the default program for opening .doc documents). So preferably this is improved so that for example the newly opened version of the word processor (for example Word) (or for example other application who has such a problem) does not register itself as the new default unless the user explicitly requests it to, or for example asks the user when the user clicks on it if he/she want this to become the default or to perform any installation, and, if not, preferably opens instantly, and/or for example the process of registering itself as the new default application is preferably done almost instantly—for example by merely changing one or a few values in some configuration file which the OS looks at when the user clicks on data files, and/or preferably at least some needed configurations are preferably saved separately for each installed version of the word processor, so that switching between versions preferably does not need any new configurations, and so preferably for example opening Word 2000 after working with for example Word 2007 or vice versa, preferably works instantly (of course these principles can be used also with other programs that have such a problems when more than one version of the software is installed). Another possible variation is that preferably the user can or example define in the OS which version should be the default version (for example in a way similar to marking a default printer and/or for example the OS by default lets the latest version become the default unless the user changes this choice) and then for example the OS automatically for example prevents the other versions of the software (for example Word) from reinstalling themselves when activated, preferably before the process even begins so that the user doesn&#39;t even see the reinstallation attempt. This is much better then the prior art, in which for example if the user has for example both Word 2000 and Word 2007 installed, then the only way to avoid too much wasting of time when switching between these versions is to let Word 2007 remain fully installed and manually abort any attempt by Word 2000 to reinstall itself when activated (because it is much easier to abort manually Word 2000 from reinstalling than Word 2007 and because Word 2007&#39;s reinstalling itself after allowing Word 2000 to reinstall itself takes much more time as explained above). Another possible variation is that preferably the user can for example create subscript or superscript also by dragging for example a letter or a marked text up or down for example with the mouse—and then the word processor preferably automatically understands the attempt and preferably automatically also reduces the font size accordingly (and if the user did not intend this preferably for example pressing ̂Z preferably instantly corrects this). Another possible variation is that preferably the word processor also preferably has a list of common words that are typically typed at least partially with superscript or subscript, such as for example CO 2  and/or learns this automatically for example after the user types the same word for example twice or more with subscript or superscript, and then preferably creates the subscript or superscript automatically by default the next time the user types the same word, and the user can for example correct it if he/she doesn&#39;t want it for example by pressing ̂z. Another problem is that for example in Word when the user switches to subscript or superscript any text typed afterwards continues to be also shifted like that and the user has to change it again explicitly to normal, which is very inconvenient since typically the user needs it just for 1 or a few typically consecutive characters. So preferably this is improved so that the word processor intelligently guesses the user&#39;s intention, so that if the user switches to subscript or superscript and types something and then starts typing for example a new word, preferably the word processor assumes by default for example that after typing a space the user intends to return to normal fonts (since normally this rarely extends beyond a single word), for example unless he/she explicitly changes again to subscript or superscript, and/or for example at least the user can choose if to enable this automatic return-to-normal mode or not. Another possible variation is that the Replace function is improved so that user can for example automatically request to replace for example all occurrences of CO 2  to CO 2  (preferably for example by being able to use ̂d also for example on the entered into the “Find” field and/or text entered into the “replace into” field or by being able to drag one or more letters up or down as explained above also within those fields). 
         [0008]    Of course, various combinations of the above and other variations can also be used. 
         [0009]    Regarding the focus-grabbing problem, preferably when the user is in the middle of typing something, preferably the focus cannot be automatically snatched away by another program (or for example by the same program, for example by a different thread, and/or for example by a different tab for example in the browser), so that for example the change of focus can occur only after the user has stopped typing for a certain minimal period, such as for example a few seconds or more and/or for example has preformed some other actions which indicated that the typing is over, such as for example hitting the Enter key or for example clicking elsewhere (which is preferably enforced for example by the OS or by the security system or for example other guardian application). Another possible variation is that other programs or other threads and/or for example tabs of the same program can snatch the focus only in case of emergency, such as for example an event that is intercepted by the computer&#39;s security system, the firewall, or the OS. Preferably this is done by allowing this only to the OS and/or the security system of the computer and/or for example the firewall, and/or any other software which has been given explicit permission by the user to have such rights. Another possible variation is that programs are not allowed to snatch away the focus while the user is in the middle of typing something, as above, but for example in case of emergency, for example instead of snatching away the focus, important messages can be displayed for example by flashing a message on some part of the screen and/or by any other conspicuous visual means and/for example by audible sound (for example a spoken vocal message), so that the user&#39;s attention can be immediately grabbed, without automatically disturbing his typing efforts. Another possible variation is that if the focus is snatched while the user was typing, preferably his/her keystrokes continue to be kept for example in a special buffer, so that when the user notices that the focus has changed and goes back to the original window where he/she was typing, the keys that he/she typed while the focus has changed are again available. This can be done for example by a special process (for example part of the OS, or some dedicated service) that keeps a copy of the most recent keystrokes and can replay them even if the keystrokes were supposedly wasted in another process that popped up during the typing. On the there hand, as explained in other applications by the present inventor that deal with computer security, preferably the security system and/or the OS can prevent programs from hooking the keyboard at all or without user permission, and preferably when the OS or security system asks for the user&#39;s permission preferably the user is informed specifically for example about attempts to hook the keyboard or to log keystrokes, since for example Zonealarm Security Suit now asks the user for authorization for programs that are trying to monitor user activities, but does not differentiate for example between keyboard logging to other activities, so the user is not sure what the program is really trying to do. Another possible variation is that preferably even if the user for example allows such keyboard logging for one or more program or drivers, preferably the security system or the OS can for example monitor and/or log what such programs are doing (preferably by hooking the keyboard and/or other resources before them and monitoring also other activities of such programs), and thus can preferably report to the user more exactly what was logged, or for example if certain things that the user typed (for example when filling form or entering credit card data, etc.) suddenly caused such programs to start new activities (for example saving in a file or accessing the web) and/or for example when keystrokes are being logged, preferably even if the user allowed it, preferably a special visible indication is displayed for example by the OS or by the Security System for example all the time or for example very frequently again and again, such as for example every few seconds or for example once a minute or other reasonable interval, such as for example some red icon on the top of the screen which says that keystrokes are being logged, preferably by hooking the relevant functions so that any access to them preferably need permission for example from the security system and cannot be done unknowingly (preferably this draws the user&#39;s attention since the user might for example allow this inadvertently or for example might not notice otherwise that it still continues). Similarly, preferably if for example the microphone for example in a webcam or a computer or for example computerized phones or mobile internet gadgets such as for example iphone or similar devices has been activated, preferably even if the user allowed it, preferably a special preferably conspicuous visual and/or auditory indication is made preferably continuously for example by the OS and/or by the security system, so that this preferably cannot be used for example for remote spying on the user&#39;s conversations without the user&#39;s attention. In addition, focus snatching for example in order to request authorization can be very dangerous, because in the prior art if the user is for example typing while looking at the keyboard and not at the screen and for example the security system or the firewall ask something without the user noticing it, then if the user continues for example to typing a word which contains the letter ‘n’ this can be considered a “No” by the focus snapping security system or firewall and if the user continues typing a word which contains the letter ‘y’ then it can become a “Yes”, perhaps without the user even noticing at all that there was a security message. So preferably, first of all, if the focus snatching has to be done for a security reason, then, as explained above, it is preferably accompanied by an auditory indication, and preferably the focus is not snatched automatically after the auditory indication, so that the user has to actively click for example on a flashing element to see what the security question is. Another possible variation is that preferably if the security software for example expects a ‘y’ or an ‘n’ for an answer, then preferably if the user types anything else then preferably the security software or the OS preferably automatically sounds an auditory error message preferably for each different character which the user types, so that the user can notice immediately that he/she is now interacting with something else. But, if used alone, this is still not reliable enough since the user might accidentally be typing for example ‘n’ or ‘y’ as the very next character after the security message appears, even though the user still thinks that he/s is interacting for example with the word processor. Another possible variation is that answering such security questions can only be done with the mouse, so that there is no way that typing at the keyboard while the user has not noticed the security message will create a reply to the security question without the user&#39;s attention. Another problem is that if the firewall becomes non-operational for example because some malware neutralizes it for example because of a malfunction of one of its essential services or components the user might even not know about it. So preferably this is improved so that for example at least for example after the boot the firewall for example automatically asks permission from the user for example at least for the initial connection so that the user can know that if this did not happen then something is wrong with the firewall. Another possible variation is that preferably the OS or the security system or some other guard application or for example the firewall itself preferably automatically adds one or more applications or components or services or processes to the firewall which are example trying to become a server and/or to access the Internet but are defined as blocked or not allowed in the firewall (or for example the user is instructed to add these definition in the firewall), and then preferably the OS or security system or other application or the firewall itself preferably checks periodically (for example very few seconds or every few minutes or other reasonable period) if these blocked applications or components or services or processes are indeed really blocked in practice (and/or for example various firewall leak test are automatically performed to check if various types of attack suddenly succeed), and if not then preferably it immediately issues a warning that the firewall is malfunctioning and/or for example blocks access to and/or from the Internet automatically for other programs for example until the user responds, and/or or for example the firewall or other guard preferably does this self check by defining automatically pseudo applications or components preferably with random names and parameters so that a malware cannot specifically relate to them, and then performs the automatic check and preferably warns the user and/or disconnects the Internet connection if it discovers that the firewall is malfunctioning, and/or if for example the firewall crashes for example due to performing an illegal command or memory problem then preferably the OS and/or for example the security system preferably for example preferably immediately discovers this for example by preferably constantly checking if the firewall is still active and/or for example by leak tests as described above (for example constantly or for example every few seconds or other reasonable interval) and then preferably temporarily blocks preferably all Internet access and then preferably automatically restarts the firewall or some other similar application. Similarly, preferably the OS and/or for example the Security System preferably automatically makes sure that for example when the computer is shutting down for example for turning off or for Restart the Internet connection is automatically disconnected before allowing the firewall to be closed, and preferably similarly when rebooting that the firewall is fully operational before any connection to the Internet can be opened, and/or even the modem itself can preferably be ordered to shut itself off for example by the OS or by the security system, as explained also elsewhere in this application. Preferably this is done by at least one component of the OS or of the Security System which resides preferably below the kernel or deep within it so that preferably it becomes active preferably before any other services or applications and preferably it is the last or close to the last element to be shut off when the computer is shutting down for example for turning off or Restart or hibernation, etc. (This is even more important of course for example in systems where there is a constantly open Internet connection with no dialer, but is preferably done as explained above regardless of the type of connection). Another problem is that for example even if the firewall protects itself against removal from memory by malicious programs, a malicious program might for example initiate a Restart process on the OS, which can remove any process from memory, and for example arrange it so that for example the firewall process will be removed first, and then for example abort the Restart without the user even noticing this. So preferably the OS or for example the Security System preferably for example requests user authorization for any Restart if it is initiated by a program or process instead of by the user himself/herself, and/or for example the same safeguards described above also prevent this. Another possible variation is that preferably if for example a program which has already been given access rights for example to the Internet suddenly requests the rights again for example from a different location (such as for example a different drive or partition and/or directory), and/or for example has been changed in some way and/or especially for example if it is a browser or for example other program which is used all the time to access the Internet, such as for example MSIE or Firefox or Opera, preferably for example the firewall or security system preferably indicates this to the user in a preferably conspicuous visual and/or auditory way that is preferably more conspicuous than normal questions by the firewall or security system, so that the user will notice that this is now another location or a changed version of the program, since otherwise the user might automatically allow it without even noticing that something unusual has happened, thus allowing for example malicious programs masquerading for example as the browser to gain access for example to inbound and/or outbound traffic. Of course, various combinations of the above and other variations can also be used. 
         [0010]    Another possible variation that is also related to the focus issue, is that for example clicking with the mouse on any part of the desktop (or for example pressing some key or keys on the keyboard) will immediately bring the desktop fully into the foreground like clicking on any other windows, so that there is no need to click for example on the special icon in the taskbar to do that, as exists today for example in Windows. In the prior art clicking on the desktop does not cause other windows that cover parts of it to move down to the task bar, eventhough it can change the focus, so the user has to click on a special icon if he wants to get a clear view of the desktop. Preferably this option is made available to the user in addition to and not instead of the icon that brings the desktop to the foreground, since sometimes there is no piece of the desktop available for clicking on it, but on the other hand, if part of the desktop is in view, it is much easier to click on it than to have to go down to the specific location of the small icon, and also in the current prior art situation it can be quite frustrating that clicking on a visible part of the desktop does not automatically bring the desktop to the foreground, unlike any other windows where clicking on any part of it does bring it automatically to the foreground. Another possible variation is that for example the clear desktop view is automatically added to the list of available options when pressing for example Alt-Tab (or other similar keys or controls for jumping between open windows or applications, including for example the flip 3d), so that preferably the user can also jump to the clear desktop for example by keeping the Alt key pressed and pressing Tab until the correct icon is reached, and/or simply pressing for example one or more keys on the keyboard in order to jump directly to the clear desktop. 
         [0011]    Another possible variation that is also related to the focus issue is to add for example a feature that allows the user more easily to define or increase or decrease the priority of various processes or open windows, since for example many times the user wishes some program to continue working on something lengthy in the background while he/she is doing other things, but many times the OS automatically assumes that if the user diverted the focus to something else, the processes that are in the background (i.e. not in focus) can be given much lower priority and so left to work much slower, so that the user finds that very little progress has been made when he/she goes back for example to a process that could have been finished in a few minutes if it was in the foreground or given higher priority (This can happen for example especially with programs that are running in a DOS window for example in Windows 98). Preferably the user can easily define the desired priority level for such background processes, for example in terms of percentages, and/or in terms of increasing or decreasing some default values for example in a few discrete steps, and/or for example in terms of more general definitions such as for example “Very high, high, medium, low, very low”, etc. Although typically a programmer can define the level of priority for a process, the user for example in Windows 98 does not have such a choice except in a few programs in which the programmers chose to explicitly give the user such an option, and also the user does not typically know which priority was set by the programmer. So preferably the OS also indicates to the user clearly, for example by colors (for example brighter colors for higher priority process) and/or by numeric and/or textual values and/or by appropriate icons, the level of priority that has been given to each process, for example by indicating it near or on each square in the for example bottom taskbar that shows active processes, and/or indicating it for example at the top line of the window of each process. For example on the square in the taskbar it can be more preferable to indicate this by a color, since there is little space, and for example on the top line of a window it is easier to indicate this for example by a combination of color and/or for example more exact numeric indication. Therefore, the default first priority shown to the user can be for example a default priority automatically set by the OS or the priority set by the programmer, or for example the priority set by the user the last time the program was run. Preferably the user can easily change the priority for example by clicking on the place where the priority is indicated at or near the taskbar and/or on the window of the process (for example at the top line), so that for example the clicking opens a preferably small windows where the user can choose the priority or for example a lever is shown which the user can pull up or down. Preferably the OS remembers the priorities given by the user to various processes and uses these defaults or at least takes them into consideration for assigning automatically the priorities the next time the user does similar things or activates the same processes, unless the user again changes the priorities. Although Windows XP for example allows the user to choose between more or less priority to background processes in general, this does not allow the user to choose it for individual processes, and the user has to go into the control panel to reach the place where it can be changed. On the other hand, in Windows XP the user may choose among a few priority levels for each process by pressing Control-Alt-Del and entering the task manager, however this does not show automatically the priority for each process, and the user has to click on each process in the task manager separately and choose from a menu in order to view or change its priority. On the other hand the user may for example use the Process Viewer (Pviewer.exe), a tool on the Windows NT Resource Kit 4.0 CD, to change also the priority of individual processes, but this requires entering a special window where all the processes are listed. Similarly for example a shareware called Priority Master (version 3.2) includes even more options, and can indicate for example the priority of a process if the user hovers the mouse for about a second above an item in the bottom task bar, and also shows this indeed on the title line of an open window. However, the above suggested improvement of constantly displaying the priority near each square in the task bar is more convenient and more efficient. Another possible improvement is that the taskbar can show automatically for example also how much percent of CPU is being used on average by each open process. Although windows XP for example allows the user to view CPU usage of various processes in a special window, preferably the user can also see this directly on the task bar without having to go through special menus for that. Another possible variation is that the priority of background and/or foreground processes is automatically dynamically increased according to the type of the work the user is doing in the foreground window, so that if the user is for example typing on Word or surfing with Netscape, more CPU resources can be automatically allocated to the background programs. This is especially important for example when DOS programs are involved since in the prior art usually if they are in the background for example in Windows 98, they can remain with very low priority even if the user is just typing or even if the computer is not really doing anything, whereas much more CPU could have been allocated to them. Another possible variation is that for example when the user enters the task manager (for example by pressing Control-Alt-Del), he/she can for example mark multiple programs or processes (for example by dragging the mouse over a range of them and/or for example by marking a group with the shift or control key pressed down and/or for example by requesting to close all the instances of the same program, for example even if they are stuck) and tell the OS to close all of them at once, instead of the prior art where the user has to mark and close them one at a time and also press Control-Alt-Del again each time (Although windows XP allows marking and closing multiple applications at the same time it does not enable doing this for processes). Another preferable variation is that preferably the task manager automatically shows near each process also to which program and/or path and file name (for example on the hard disk) it belongs. Another possible variation is that preferably the user can choose to automatically sort the processes shown in the task manager for example alphabetically and/or according to how much resources they consume (for example CPU, memory, Internet bandwidth, disk space, etc. and preferably the user can choose for example according to which resources utilization to sort the applications and/or for example to give different weights to various resources so that they are sorted for example by a formula that reflects the importance of the resources), and/or for example according the programs they belong to, and/or other criteria. Preferably this can be applied also for example to tabs within the browser (and/or within other application that have tabs and/or for example various types of threads) so that for example the tabs can also be similarly sorted in a table for example according to one or more of the resources, and/or for example if some tabs consume for example more than a certain absolute or relative threshold of too much of one or more resources, such as for example memory or CPU preferably for example the browser automatically marks them for example with a special color or shape in their tab handles or for example some icon or other visual indication, so that preferably the user can easily see for example if one or more tabs are for example running some java or javascript or active-x or other code which is consuming for example too much CPU time or for example too much memory resources and/or other resources, and/or for example the browser preferably automatically stops any code activity in a tab which the user is not currently looking at for example immediately after the user jump to another tab or for example after s short time threshold (such as for example 10 or 20 seconds or other reasonable period), or automatically gives such activity much lower priority when the tab is not at the forefront (preferably for example except downloading of files which the user explicitly requested), and preferably the table of resource utilization of programs and/or services threads and/or tabs, etc. is preferably displayed automatically for example by the OS or for example by the security system whenever some program or thread or service or tab or OS process exceeds for example some relative or absolute threshold or for example exceeds some statistical deviation threshold from its previous history of typical behavior. Another problem is that for example in windows 98 many times the user has to try multiple times to close an application through Control-Alt-Del (or for example when the system tells the user that the application performed an illegal action and asks the user if to close it) until the application is really closed. So preferably in case it hasn&#39;t been closed the OS automatically tries again repeatedly to close it, preferably for example at least for a certain number of times and/or till a certain time limit, and preferably the OS lets the user know if there is still a problem after the number of times and/or the time limit has been reached if the OS was still unable to close the application. (Preferably the automatic re-attempting is also accompanied by some visual indicator which preferably shows that the system is automatically continuing to work on closing the chosen program or programs and preferably lets the user automatically know when the system has finished closing the program or group of programs). Preferably the OS can also show the user automatically in which stage the OS is in trying to close the application and/or for example what is the specific problem or problems if there is a problem or problems. However, preferably when the user requests to force an application to close preferably the OS does it instantly even if the program is stuck—for example by removing immediately the relevant task from the scheduler, especially for example if the stuck program has no disk activity, and/or for example also if there is disk activity (since that might be very dangerous for example if the application has been for example compromised by buffer overflow), so that for example if the stuck program is trying to perform disk activity, preferably the OS can for example stop it immediately for example after it completes one or more transactions or for example if it does not stop after a preferably short time, such as for example after 1 second or s few seconds 10 seconds or other convenient limit which the user can preferably change, and/or for example in case of emergency, for example if the user thinks that some program might be causing damage to files or directories, preferably the user can activate for example an even more urgent abort command which preferably stops any program preferably instantly even if it is performing disk activity, and/or for example this is activated automatically for example if the OS or the Security System finds indications of suspect or unusual behavior. If for example the stuck program has also other running processes that belong to it or were activated it which are for example interacting or for example causing a deadlock with running applications, then preferably the OS also similarly preferably closes also these processes preferably immediately or significantly faster than the prior art, for example by any of the above described means, and/or for example even if some trace activities take longer to terminate preferably at least once the stuck program stops slowing down the computer it is preferably immediately removed for example at least from the taskbar and/or from the alt-tab so that it doesn&#39;t bother the user. This is much better than the prior art since for example in prior art Windows the user can sometimes wait even a few minutes for an application to close even when trying to force it, which can be very annoying and unacceptable. Similarly, preferably if the user wants for example to perform an instant Restart or Instant Reset but without waiting for applications to close and without risking file damage or having to run scandisk after or during booting, preferably the user can for example press some control or for example key combination which preferably freezes all writing activity on the disks for example immediately or after a certain preferably small period of time (such as for example a few seconds or more or other reasonable interval) or for example stops each disk activity at the end of a transaction, and then preferably the system can preferably automatically restart for example without the user having to press an additional control, or for example after disk writing activity has been frozen the system for example indicates to the user that it is now for example safe to press the Restart button. Of course, various combinations of the above and other variations can also be used. 
         [0012]    Regarding installation of a new operating system in a new directory or partition, preferably during the installation the new system preferably automatically copies the desktop configuration and links from the old system into the desktop of the new system. Since some installed components will not work the same between two different versions of Windows (such as for example when running installed components of windows 98 on windows XP), preferably the system automatically checks which programs can work automatically without problems also in the new system (for example applications that don&#39;t have to access the registry, etc.), and preferably for example indicates to the user which applications might need some adjustment and/or tries automatically to solve this problem for those applications too. There are a number of possible preferable solutions for this, of which preferably at least one is used:
       1. During installation of the new system, preferably the system tries to automatically convert components that are different between the two systems to work on the new system, for example by automatically converting system calls, memory structures (if needed), etc.   2. During installation of the new system, preferably the system tries to locate the original files which were used for the installation and then tries to reinstall automatically the correct drivers or components that are needed for the new system. For this, preferably each Windows system keeps information (for example in the registry and/or in one or more of the directories where the installed program or component or drivers resides) about the path and name of the original file from which it was installed, so that the installation can be automatically repeated into the new system, this time with the components that are needed for the new system. If for example the same item can run also on the new system as is (and/or for example the new system is in general compatible with the old system anyway—for example Microsoft Vista is installed on an additional partition and the previous installation is XP) then preferably the user is automatically asked for example if he/she wants for example all or some (or for example asked for each icon separately) if the copied desktop icons should point to the same application as installed on the previous OS or for example a new separate installation should be created for example in the new partition for the new OS, and/or for example a Copy-on-Write version of the application should be created.   3. If the system does not succeed in converting the relevant links or components to work on the new system or for example the original installation program is limited only to the old system (for example Windows 98) and does not contain for example drivers for the new system (for example Windows XP), then preferably the system marks the relevant links on the new desktop as non-operational (for example by giving them dim gray color) and encourages the user to look for other versions of those programs that are fitted to work on the new system. Another possible variation is that in such cases the system allows the link to activate the version that runs under the old system (or for example creates another copy of it) and uses emulation of the old system when needed in order to let it run (at least temporarily until the user installs the new version). Another possible variation is that the system can automatically try to locate on the Internet (preferably in a limited list of well certified sites) any needed variations or drivers that will work on the new OS and for example recommends them to the user and/or for example can download them automatically from certified sources (preferably of course only after user authorization for each downloaded file). (This is relevant mainly for example for shareware programs).   4. Preferably a new protocol for installing programs is implemented so that each installation of new software preferably installs both the appropriate drivers or components (for example Windows 98 drivers on a windows 98 system) and one or more sets of alternate drivers or components (for example for Windows NT/XP or other Operating Systems), and preferably each time the program is loaded into memory the appropriate set of drivers or components is automatically chosen by the OS. However, since in some programs part of the installation requires for example updating registries and/or installing various components in system directories, preferably those parts of the installation are suspended and are executed automatically for example the first time that the new OS is activated for the first time after installing it.       
 
         [0017]    Another possible variation is that when installing the new system the new OS first copies the old system, preferably as is, into a new partition (which preferably the user can specify, and the system preferably creates it automatically if it doesn&#39;t exist before), and then preferably all the references to the drive letters of the original partition in the OS and preferably also in the existing applications are preferably automatically replaced to refer to the new drive letter (for example by changing them on the disk or for example by an application which runs below the application and corrects the driver letter on the fly when needed—for example whenever the relevant file access services are activated). After that preferably the system installs the new OS over the new copy of the old OS (or for example over the original copy of the previous OS—preferably by offering the user to choose between these options), in a way similar to a normal upgrade installation. After that if there are for example compatibility problems with programs that are not fit for the new OS, as explained above, preferably any of the above described solutions can be used to solve this. The end result is that the user has a new OS either on the original partition or on a new partition, without losing the original OS. Another possible variation is that preferably the same principles can be used also for example for porting the OS together with the installed programs to a new computer—by first creating an image of the installed OS of the old computer preferably in a way that is independent of specific disk sectors, then loading this image on the new computer, and then installing over it the new OS, or for example again installing it in another partition, thus creating on the new computer for example preferably a bootable working mirror of both the old OS and the new OS. 
         [0018]    Of course, various combinations of the above and other variations can also be used. 
         [0019]    Regarding the undo problem, preferably any changes in the entire hard disk or other types of preferably fast mass storage non-volatile memory after or during the installation of new software, are preferably completely undo-able at least for a certain time period. This is more comprehensive than the current “undo” feature that Microsoft for example offers after installing new software, since the current features only allow restoring the registry and system files, and even that not always completely, whereas any other changes to directories or files cannot be undone. A more extreme variation is that for example any changes at all that happen on the hard disk or other non-volatile memory (and possibly even on other connected media) at any time are completely undo-able at least for a certain time period, in a way similar for example to the undo feature in a single Word document. The above Undo features are preferably accomplished by keeping one or more rollback log, preferably backed up by appropriate hardware on the disk—as explained below in the reference to  FIG. 2 . 
         [0020]    Other possible improvements in word processing programs such as for example Microsoft Word can include preferably at least one of the following:
       1. Adding to word processors such as for example Word, for example a smart file-compare features that can show exactly the textual differences between two or more files while disregarding irrelevant data such as line breaks, fonts, etc. In the prior art this can be done for example by a text file compare program after saving the word file as text files with line breaks, but then the comparison might show many irrelevant changes for each paragraph because of changes in line breaks for example if even one word was changed near the beginning of the paragraph. Another possible variation is to allow the program to merge for example two files into a single file with highlighted changes just as if one of the files was created out of the other while keeping the “highlight changes” option to On. This is very useful for example for checking changes between a current version of a file and any of the previous versions retroactively even if no change tracking was used during the time that the changes were made. In order to accomplish this preferably the changes are checked in a way similar to the non-merging file comparison, except that the results are displayed in the form of the merged file. Another possible variation is that for example cut &amp; paste of one file over another file (and/or in fact cut &amp; paste a section, such as for example a few words or a few lines or one or more paragraphs, over another section) when “highlight changes” is set to ON automatically generates the highlighted changes between the two sections as if they were made by actually changing one to the other, instead of the current prior art in which the results of such cut &amp; paste are that the old text area is simply marked as deleted by strikeover and the new text is simply marked as added (this is preferably accomplished, again, by simple automatic comparison between the original text and the pasted text, and marking the differences by the conventions of highlighted changes, as if the changes were made manually). Although Microsoft Word currently allows an option of file comparison, which marks the changes between the two files as if the “track changes” was set to On between the old file and the new file, as explained above comparing sections by cut and paste does not work (the previous text is simply marked as deleted and the pasted text is marked as new, instead of making a comparison), and even the comparison of two files is not sufficiently reliable and has at least the following problems:
           a. If at least one of the two compared files already contains marked changes, Word warns you that it may not be able to show all the changes, and there is no differentiation between previous marked changes and the changes that are indicated by the comparison itself. In order to solve this preferably in such cases a different indication is used between the old changes and the new changes generated by the comparison, for example by using additional colors, and/or using for example different special icons and/or marks near the old changes and/or near the new changes, and/or using for example different special squares and/or other frames around the old and/or the new changes, and/or using for example special fonts and/or other font characteristics, and/or other preferably clearly visible indications. However, using for example different colors could be problematic since different colors are already used for indicating who made each set of changes, so this might be confusing, and in addition, if such a file (that resulted from a comparison) is then again compared with another file, more and more colors might be needed. A more preferred variation is that for example in each stage of the comparison the old changes are automatically marked for example by more faded or less lit colors (but preferably keeping the original colors), and if comparison steps continue then preferably at the next step preferably all previous changes now become faded, and the new comparison changes are marked with brighter colors. Another possible variation is that for example at any time the user can activate a command which tells the word processor to start using a new color for the changes, which can be very useful for example when the user wants to keep previous changes marked but also to differentiate between them and new changes. Eventhough the user can achieve today a similar result in Microsoft Word by changing the author, such a change just in order to change the color of the tracked changes is confusing, so preferably the user can change the color without changing the author. This is preferably done for example by adding an option to the menu of track changes, which preferably enables the user to choose separately the color of changes that were made so far and the color of subsequent changes (preferably with a free independent choice of colors for each and preferably more or much more than 10 colors are available—preferably for example any color which is available for graphics, and/or for example preferably the user can also request for example that text of marked changes for example for a specific author and/or from a specific date and/or for example for all authors and/or dates will preferably have a different design than normal text, such as for example different inclination or different font or different width and/or height, however changes that change the size of the font are less preferable because that means also changes in pagination which will revert when the changes are accepted, so the use of more available colors is more preferable), or for example the user can indicate for example a time and date from which the new colors apply (and/or for example also until a certain time and date) (which can be useful for example if the user already started to type in the new changes and then decides for example that all the new changes for example since today should be marked with a different color). Preferably the user can also change any color of tracked changes to any other color (preferably at least a few hundreds of possible colors are available), which is very important since sometimes for example Word decides on its own to suddenly for example switch colors between authors (for example simply closing and reopening the document can cause the color to change), which can be confusing or annoying since the user can already be used to a certain color as the color of the current changes), or the user might for example simply prefer a different color. For changing the colors preferably the user can for example use the search and replace command with the color as a parameter, so that for example changing the color of tracked changes can be done the same way as changing the colors of normally colors sections, as described elsewhere in this application, and/or for example the user can for example right click with the mouse (or for example use some other command or control) on one of the sections with the old color and then for example choose the new color from a menu, so that all the tracked changes with the same color change into the new color, and/or for example the user can (for example in the menu of the track changes options) for example edit a table which lists all the current colors of tracked changes (preferably together with the name of author of each color or for example the range of dates covers by each color) and then the user can for example mark near each of them the new desired color and then for example click on an option which activates the changes, which is most convenient for example in case the user for example wants to switch between two colors, for example convert the blue tracked changes to red and vice versa). Another possible variation is that preferably the word processor saves also a code of the specific color used for each set of track changes and does not change it on its own. Another problem is that for example in Word 2000 and even in Word 2007 the vertical line on the side that shows areas of change in track changes is sometimes shown over part of the text (for example when it is shown on the right and the right margins are 2.5 centimeters from the right edge of ha page), which can be annoying or confusing or make it harder to read. So preferably this is improved so that if such vertical line is shown then preferably it is always automatically removed beyond the edge of the text (for example by automatically making sure that it is preferably for example at least 0.5 centimeter away from the edge of the text, or for example any other reasonable distance) and/or for example the user can also specify the desired distance from the edge of the text and/or for example how visible or conspicuous the line should be, and/or for example the user can specify independently if this line will be shown on the screen and if it will be shown when printing the document. Another possible variation is that even with the prior art method of having to change the user in order to change the color, preferably more than 10 color are available and preferably the word processor displays in advance all the available colors and the user names that can be associated with them (for example the same name with an incremental number) so that the user can know in advance what color will be given to the next user name instead of having to guess or use trial and error even just to find the desired color. Another possible variation is that preferably the user can tell the word processor for example to avoid marking tracked changes for example on the page numbers and/or the date and/or this is preferably the default, since this marking this is unnecessary and makes the title line ugly. Another possible variation is that for example when the user executes the “accept changes” command he/he can for example request to accept automatically for example (with or without individual confirmation for each change) for example only the changes of a specific author and/or color and/or for example group of color and/or for example accept all changes except a specific color or colors, and/or for example accept all changes from and/or until a certain date of when the change was made, for example automatically accept all the changes that were made until Dec. 12, 2005, and/or for example similarly reject for example a specific set of changes selected this way and/or for example search text in a specific set of changes selected this way. (Preferably when the user chooses the relevant accept/reject changes menu he/she is offered the color options for example as color bars or squares which he/she can mark or not mark and/or the date options for example as fill-able fields or moveable dates). Another possible variation is that preferably the user can for example also activate a command which for example removes from a file all the text except the tracked changes (or for example only a subset of the tracked changes, for example by author or authors and/or color or colors and/or date range), or can for example mark automatically all the tracked changes or a subset as explained above and then for example automatically copy only the tracked changes or a the subset of them to a separate file. Another possible variation is that this is done together with intelligent heuristics, so that for example if the tracked changes are in a middle of a sentence then preferably the entire sentence is copied (or in case of deleting everything except the track changes the sentence is preferably kept.) Of course after the deletion or copying preferably the tracked changes retain their colors and insertion date information (for example unless the user explicitly requests otherwise). Another possible variation is that the user can for example use the right mouse menu (and/or for example some control key or keys) to delete for example all of the current paragraph. Another possible variation is that the user can preferably also change the author for example for only a specific document or specific group of documents (instead of only globally as it is in the prior art Word 2000 and even Word 2003), and in this case of course this definition preferably carries on also every time the user saves the file under a new name until the user explicitly changes the author again. However, these are just examples and any type different marking can be used. Another possible variation is that for example a summary table or other type of index is automatically generated so that the table or index indicates which color was added on which date (preferably taken automatically from the date of the file which each color of changes represents), so that the user can clearly see which change was entered at each date (and/or time). Another possible variation is that, in addition or instead, the date in which each section or element was added or changed is automatically indicated near the relevant text, for example by a bubble that is shown when the user points the cursor or the mouse on the relevant section, but more preferably this is marked all the time, preferably at the side or margins of each section (so that it doesn&#39;t cover any text), so that it is clearly visible even without having to hover over the section, and preferably it is clearly visible also in the printed version near each section (of course the user can preferably also request to disable or hide this for example on the screen and/or when printing, and/or for example activate this only for example only for a certain section—for example a certain sentence or an area which he/she marked with the mouse). In order to accomplish this preferably at least when two or more file are merged preferably the files are automatically sorted by date before creating the comparison, and each new section or element is dated automatically according to the first time it appeared. (Although for example Word 2003 can show the time and date each marked section was added when the user puts the mouse over it, this works only while the section is marked and cannot be reconstructed after the changes have been accepted, as described above, and for example when two files are merged for comparison the added parts in Word 2003 are marked as if they were added at the date of the comparison. So according to the above variations this is preferably improved so that preferably if the added section was not previously marked as a change then the date shown is the date of the file from which it was added, and if it was marked then of course the original date is kept as originally marked in the changed section). (Preferably the above generation of the date each section was added can preferably be done with or without requesting file merge, and preferably the user can mark the set of relevant files for example by marking multiple files in the dialogue box that shows the directory, or for example the word processor preferably automatically keeps a history log of file renaming and/or saving under a different name and so preferably when the user requests the word processor to enter the date each section was added, preferably the word processor can automatically generate the relevant list of files from this history log). Another possible variation is that preferably the word processor can automatically save for example the time and/or date information for each section also after it is accepted and/or even when track changes is not used at all (preferably by simply keeping this automatically), but in that case preferably it is saved locally, for example in the same directory, preferably with some link which relates it to the file, but preferably does not become part of the file, so as not to damage the privacy of the user if he/she for example sends the file to someone else (of course the user can preferably disable or enable these options, and/or can preferably for example also request this information to be kept within the same file)(Preferably the linked file that contains this information is automatically copied when the file is for example copied to another name and/or directory or saved under a different name and/or renamed along with the file if it is renamed, but preferably the user can also easily delete this file for example if he/she so desires, so preferably this linked file has a simple name convention, such as for example the same name as the document file, but for example with a different automatic extension and/or with some automatic addition to the name itself). Another possible variation is that such information about the date each section was added (which, as explained above, can preferably, at least as one of the options, preferably be automatically generated even if the text was entered without track changes), can also be for example kept if the file is saved for example in PDF or XPS or other format, so that preferably the date each section was entered can preferably be shown for example also in the converted format when the user hovers with the mouse over it, preferably unless the user for example disables this or for example only if the user explicitly enables this before converting to the other format and/or for example requests this for the specific conversion. Preferably when the date a section was added is displayed for example on the side of the section, preferably the word processor can display for example one date for each consecutive text which has the same color in the track changes (even if there are different dates within the text of the same color)(which can be for example the first date or last date or for example both of them or for example the average date—preferably it is by default the min and max date next to each other, with a range indicator between them, but preferably the user can easily change this). Another possible variation is that the user can for example define some conversion table which indicates for example a list of conversion rules, so that for example that all texts added between a certain range of dates will be marked by the word processor (preferably on the side) as having been added at a specific date, all texts from a second range will be marked as having been entered on another date, and so on (this can be useful for example for quickly keeping track of the priorities of sequential patent CIP filings of the same cumulative patent since for example changes entered between a certain range of dates might have been submitted for example 1 or 2 days later than the last entry of that section and of course even more days after the first entry of that section). Another possible variation is that for example if there are different dates within the text of the same color preferably the word processor can also for example automatically draw a curved line that surrounds each inner section which has the same date and then indicate the date of this subsection for example on the side with an arrow that points to the sub-section (this level of detail is more similar to what happens when the user hovers with the mouse on the section because then the date of each subsection is displayed). Preferably the text with these markings can be both displayed on the screen and printed. However, if the information about dates entered is kept also without track changes preferably the user has also an option of removing it for example into a linked file or for example removing it completely (for example by saving the file under a different name so that the original file with the information still exists), which can be important for example if the user want to send the file to someone else and does not want this information to remained there, and preferably the word processor for example automatically adds some code for example to the file name or to its extension or for example marks in some other preferably conspicuous way if the file contains date-entered information even for sections without track-changes or not. Another possible variation is to use similar fading for example also with normal incremental changes when track changes is used, so that for example the user can use a command that fades (or otherwise changes) the color of preferably all the older changes so that all the new changes from that point on will stand out. This is very important for example when a file is changed in incremental steps and each time for example the new version is sent by email to someone else. Another possible variation is that for example the OS and/or the word processor can identify automatically incremental updates of the same file (for example according to the beginning of the file name and/or date and/or for example by keeping automatically a log of the sequence of updating a file incrementally), so that the OS and/or the word processor can use the knowledge of the update sequence of a series of files for example to search for example for each section or sentence when was the first time that it was entered. Another problem is that for example if the user moves text when track changes is on (for example by cut &amp; paste or by dragging directly with the mouse), the place where the text has been moved to appears as if it was added only at the moving date, without indication of the fact that the text already existed in the document for example a long time ago, but just at a different place. So preferably this is improved so that the word processor preferably automatically keeps track of such movements (for example directly if the user moves the text for example by dragging it with the mouse, and for example in case of copying the text and deleting it from the original place and then for example using paste to add it in the new place, preferably the word processor for example keeps track of from where the text was copied and preferably preserves also the time the original text was entered even if it is not marked by track changes, as explained elsewhere in this application), and preferably after the user inserts the text in the new place the word processor can preferably display there for example both the fact that it was moved on a certain date and the fact that it had existed before in another place in the document since the previous date (and this double information is preferably shown for example in a bubble and/or for example at the margins of the page if the user for example hovers over there with the mouse).   b. The file comparison is not always reliable and may get sections confused, so that for example when comparing two patent files, the comparison can confuse for example between a claims section and a specification section, thus marking entire areas as deleted and added instead of properly comparing them. In order to prevent this, preferably the system uses preferably various heuristics in order to extract from the document important information about its structure, so that for example a section that appears after a clear headline (which is typically for example on a separate line and is typically emphasized for example by boldface and/or by underline and/or sometimes for example by capital letters) is preferably automatically recognized as a different section of the documents, and this way for example a section that appears after the headline CLAIMS will not be confused with a specification section. In addition, the system can use for example other cues about each section, since for example the claims section is clearly characterized by short paragraphs that each start with a consecutive number, which is unlike any other part in the document. Such cues and/or heuristics are preferably used in a fuzzy manner, so that they are considered as part of the evidence but not as absolute guidelines, so that for example if there is more evidence that indicates otherwise, such cues can preferably also be ignored. For example a thorough academic article from 1988 about file comparisons at http://citeseer.nj.nec.com/cache/papers/cs/6985/http:zSzzSzwww.ime.usp/brzSz˜zSzpapirzSzsctp.pdf/simon88sequence.pdf shows that the file comparison problem is theoretically and practically not completely solved yet, but this article deals mainly with various methods of increasing the speed of such algorithms (which is far less critical today, now that computers are thousands of times faster than 15 years ago), and much less with how to improve the reliability of such algorithms. U.S. Pat. No. 6,526,410, issued on Feb. 25, 2003 to the Hitachi company, shows how to improve such algorithms in explicitly structured documents, such as for example XML documents, by making the comparison first between the XML structures, and then comparing the text only between structures that are determined to be within the corresponding sub-structure, and typically working with a table of explicit comparison rules. However their solution does not solve the problem for example for Word documents, which are the most common type of documents for example in legal documents such as for example contracts and for example patent applications, where file comparison can be very important. Therefore, the above suggested solution is much more general since it can work for example also with word processing documents, such as for example Word documents, where there is no explicit hard-definition structure, but smart heuristics can easily use relevant cues to identify actual sections, and in addition the above solution is more flexible since the identified sections preferably don&#39;t become absolutely binding, so that for example if other criteria (such as for example the percent of the common sequences found) indicate that it is better to ignore one or more apparent section indicators, this is preferably done. In addition, preferably the same principles are used and applied recursively when needed. Another possible variation is that for example if the user sees that a certain part of the documents (or more than one part) has not been properly merged (for example the end of the specification together with the claims), then the user can preferably for example mark, for example with the mouse, the problematic section or sections, and then tell the system to try again to merge more properly the problematic section or sections, and then for preferably the word processor (or other application) can work much better because is has a much smaller problem area on which to concentrate.   c. Only 2 files can be compared at each step. So instead, preferably the system allows to compare also more than two files in each step, and so in the merged file of for example 3 files, changes that come from different files are preferably marked in different colors (for example in a way similar to marking changes that were added by different people in different colors), or marked differentially by other methods, for example such as those mentioned in clause ‘a’ above.   
           2. Another big problem with the current track-changes features that exist for example in Word 2000 and Word 2002 and even in Word 2003 is that if the user for example breaks an automatically numbered paragraph, where for example each part is automatically marked by a letter or by a number (such as for example in patent claims) into two paragraphs, the part after the break becomes marked (typically in red) as if it is a new text, instead of marking only the real change, which is the new line break and the changes in the subsequent automatic numbers. On the other hand, if the user makes the changes without the track-changes feature On and then uses file-compare, the comparison does not mark the text after the break as a new text (which is good) but now the showing of the changes in the subsequent automatic numbers is not done). This is of course a problematic lack of consistency. So preferably this is improved so that when the track changes feature is On and the user breaks an automatically numbered paragraph, only the new break and the change in subsequent renumbering is shown and the part after the break is not marked as new text, and when comparing files the same consistent difference is shown. In addition there is a problem that when a text is marked as deleted, for example as a result of track changes or of file comparison, if the user wants to undelete it or part of it, the user cannot do it directly (unless it is the most recent change and can be restored by normal Undo), and the user cannot even mark and copy the deleted text and convert it to non-deleted text. Although in the prior art Word the user can do it by marking the deleted text with the mouse and then going the “accept/reject changes” and rejecting the changes in the marked area, but this is much more cumbersome. So preferably this is improved so that when a text is marked as deleted as a result of track changes or of file comparison, the user can mark the deleted text or part of it and press for example a key or button or for example right-clicking with the mouse and choosing undelete from a small menu or otherwise execute a preferably single command which can instantly undelete it. In addition, the user can preferably also mark and copy text that is marked as deleted or any part of it and can preferably paste it back at the same place or elsewhere for example as normal text. (Another possible variation is that he can choose for example if to paste it as normal text or as text marked as deleted). Another preferable improvement is that preferably the user can switch between the Track changes On and Off states also by some control key instead of having to go through a series of menu choices, as it is currently in Word. In addition, preferably when the user copies and pastes text that contains marked changes (for example within the same file or between files), the user can preferably indicate, preferably when pasting, if he/she wants the pasted text to contain the marks of the ‘track changes’ or not. Another possible variation is that the user can for example mark one or more areas in which track changes is marked as On (or Off), so that the other areas for example remain with track changes Off (or On), etc. This can be very useful for example with the new required format for amendments in the USPTO, since when answering for example an Office action the user typically has to use track changes when making changes in the area that contains the amended claims but remove the track changes when moving to the comments section. In addition, in the prior art, even when just working on the section of the amended claims, the user has to switch to track changes Off when adding for example the words “(Original)” or “(Currently amended)” at the beginning of the claim and then switch back to track changes On when changing the claim itself, etc. So preferably, the user can for example automatically add for example the default of the word “Original” at the beginning of each claim for example by using a command that allows defining an automatic rule for this structure, as explained above, and then for example define or choose in the automatic rules command (or for example mark the entire claims area and define in the claims area) a mode which for example automatically adds for example the “(Currently amended)” when the user makes changes in that claim, so that the user does not have to switch to Track changes off, and the words “(Currently amended)” are preferably automatically added without track changes and other changes in the claims except in the opening bracket are preferably marked by default with track changes when in this mode, and areas outside the claims are preferably automatically not marked with track changes when in this mode. (Preferably this mode can be for example defined for example in a preferably small macro file or other type of parameters file which the user can preferably download for example from the USPTO and then the user can preferably simply activate or deactivate this mode while working in the word processor, for example by clicking on some icon or icons and/or by pressing some control or controls). Similarly, in this mode preferably for example deleting an entire claim preferably automatically causes the deleted text to disappear, and the word “(Canceled)” to automatically appear instead, as if track changes has been temporarily suspended. Similarly, for example when adding new claims at the end of the claims section, preferably the track changes is automatically set to Off and the word “(New)” is preferably automatically inserted at the beginning of the new claim. Another possible variation is that if the user for example made a mistake and typed text in “track changes off” mode and wants to make the new text marked, he/she can for example use ̂Z to temporarily remove the newly entered text, activate the track changes and then for example type ̂y and the new text preferably automatically becomes marked. Another problem with the track changes feature is that typically on the screen the changes are most conspicuous when shown in color (especially for example in red, which is the default for example in Word, if only one user makes the changes), however when printing the file for example in laser printers the red typically becomes a weak gray shade which can be difficult to read. Although Word allows the user to change the color of the marked changes for example from the typical red/blue to black, in the prior art this affects both the on-screen display and the printing, which is very inconvenient for the above reasons. So instead preferably this is improved so that the user can preferably define separate colors for displaying the changes on the screen and when printed. Preferably by default the on-screen display is the automatic colors, and the printing is preferably by default in black if a black and white printer driver is used and preferably automatically by default in color if a color printer is used (or for example black by default also in color printers unless the user changes it)(Typically the system knows which type of printer is used either by plug and play or by the default printer driver), or for example the user can request (for example by setting some default in a menu) that when printing the word processor or the print driver for example ask him automatically if to print the track changes in the original colors on in black. Another possible variation is that the user can for example also change these definitions in a way that applies only to a given file, instead of being able only to change it globally in a way that affects all files until changed again by the user, and/or for example change these defaults for all the files in the same directory and/or for example change it automatically in all the files with have a very similar file name or for example identical first characters (for example first 7 characters or for example first 50% of characters, etc), or for example all files which are previous versions of the same current file (which means that preferably the word processor also keeps automatic track of version history and/or for example generates this automatically for example according to file names and/or sequential numerals and/or time &amp; date, etc.). Similarly, preferably the user can for example define if by default printing for example into a pdf file, such as for example with the CuteFTP program, will keep the color of the track changes or change it for example to black, or for example the user can request (for example by setting some default in a menu) that on each such printing into a pdf file the word processor or the print driver for example ask him automatically if to print the track changes in the original colors on in black (since for example when printing into a pdf file for sending to the USPTO it is better to make the track change black, but for normal purposes the user would normally prefer to keep the different colors of the trac changes in the pdf file). Another possible variation is that preferably the user can for example automatically convert marked additions for example to normal underlines, and/or for example vice-versa—automatically convert underlined sections into sections marked with track changes. Preferably the word processing program can ask the user automatically for various types of changes in the way the word processor operates if the change is intended only for the current file or for example for all the files in the same directory or for example all of the files of the same sequence all the files in general or for example one of the other options detailed above. Another problem is that the strikeout on some characters is almost invisible—for example the digit 4 has a horizontal line almost at the exact position of the strikeout line. So preferably the strikeout line is automatically moved higher or lower on such characters, or for example in a line or a word or a section where such characters exist the entire strikeout line is automatically made lower or higher as needed (for example by 1 or more pixel lines), and/or for example the strikeout line is automatically made of a different thickness and/or length and/or angle and/or color (for example just over the problematic character or over the problematic word or section or line). Another problem is that for example in Microsoft Word if the cursor stands on a word that is marked as deleted and the user enters the dictionary, the word is not seen by the dictionary, and trying to access it in the dictionary can also cause the cursor to jump one word backwards. So this is preferably improved so that the striked-out words behave like normal words on the dictionary. Another possible variation is that for example when a section (for example one or more characters or words) is deleted and then reentered next to the deleted text (for example a deleted digit 9 next to a newly entered digit 9), preferably the word processor can automatically decide to integrate them by removing the deleted redundant part, since it adds no information and looks confusingly like a change where there is really no change, so that for example “thethe” becomes automatically “the”. Another possible variation is that preferably, when the color of the changes is set to be according to the user, the word processor allows the user to choose by himself/herself what color his/her new changes will be (and/or what the color of previous changes will be), since in the prior art this is determined automatically and sometimes for example Word can assign to the user by mistake a color that already belongs to one set of changes even if these comments were not made by him/her. Another problem is that for example in Word 2003 the marked changes are shown in a way that might be confusing or inconvenient for example to users who are accustomed to the way that the changes are shown for example in Word 2000 (especially for example the way deleted text is marked with comments at the side). Although Word 2003 allows the user to view the changes in the old format by choosing “Normal View” instead of “Print layout” in the “View” menu, this is problematic because in this mode the user cannot see the page numbers and in fact cannot see at all the headline of each page, and graphic images are not shown. So preferably this is improved so that the user can choose to view the track changes in the old or the new format preferably without affecting the way the headlines and page breaks and/or images are shown, and preferably the user can toggle between showing the page numbers and headlines or not independently of the format of the marked changes. Another problem is that in the new marked changed format if the user for example simply moves the mouse over for example text which is marked as newly added, many times suddenly a yellow square appears which repeats the inserted text and gives the time and date that it was inserted, but this yellow square many times covers partially the original text, which can be very annoying. So preferably this is improved so that the time and date or at least the date appears only at the side without covering the original text, and there is no need to repeat it anyway.   3. Another problem is that for example when activating the compare feature between 2 files in Office 2007 the word processor offers for each of the 2 file names only to choose from a limited list of 10 recent file names (which typically are not even recent files used for comparison) or to browse the directory to pick another name but does not enable the user for example to pick a recent name and then change something in it, which can be much faster if the user is for example continuously working on the same file and is saving it incrementally for example with the same name ending with an incrementing number. So preferably this is improved so that the user can also change the name after picking it up from the offered recent names, so that preferably clicking it brings it into a line which the user can edit before finally picking the edited name. In addition, preferably the list of recent files offered on each side (typically the left side and the right side for example in Word 2007) in the file compare menu compare preferably reflects correctly the most recent files used for example on that side (or even for example those used on the other side, in case the user for example made a mistake and needs to swap the sides). Another problem is that for example both in Word 2000 and in Word 2007 the list of offered files in the Open-file dialogue box does not learn from recent files used for file comparison or vice versa, eventhough many time a user might for example normally open and edit one or more files and then use them for the file comparison, or for example compare files and save the results, and then for example might want to reopen it a short time later. So preferably this is improved so that files recently opened for example for file comparison preferably become automatically offered also for example when opening files and vice versa (which means that preferably the relevant dialogue boxes share the same list of recent files or for example file names are copied between their lists). Another possible variation is that preferably when making such a comparison between the two files preferably the word processor for example keeps showing the two file names also after the merging is complete or for example they appear at the top of the list of recent files in each side, so that the user can make sure for example that he/she did not make a mistake when choosing the names of the two files to compare. Similarly, for example when reopening a recently opened file, as offered for example by the word processor when the user requests to open a file (for example from the top left corner options round button for example in Word 2007), preferably the user can also pick a name from the automatically offered list of recent files and also edit the file name before actually opening it, if so desired (for example by having to click twice to choose as is, or for example by clicking with the right mouse button if the user wants to change the name. Another possible variation is that preferably the user can also request for example a comparison between two files which already contain tracked changes—preferably for example with an option to mark also the changes between the two versions of the track changes, in which case preferably the word processor for example indicates (for example by a special color and/or for example marking) places where there are differences between the 2 files in what tracked changes are shown. Another problem is that for example when saving the results of a file comparison of for example word 2007 which contains also moved sections for example in the format of word 1997-2003, the word processor coverts them into deletions and insertions but the user cannot see what sections are involved. So preferably this is improved so that when asking the user about the conversion preferably the word processor also includes for example a link which lets the user view the moved sections. Another possible variation is that preferably opening a file from the automatically suggested list of recently opened files preferably also automatically sets its directory as the default directory, which makes sense since the fact that the user opened the file this way with a single click does not mean that he/she wants the default directory to behave any differently than if he/she had opened it normally the longer way. Another possible variation is that preferably when the list of recently opened files is displayed preferably the word processor also shows near each file name also its extension—preferably all the time and not just when hovering over it, and similarly preferably also the drive letter and/or full path is shown preferably all the time when the list is shown. Another problem is that for example, both in Word 2000 and 2007 when the user uses the open-file dialogue box only the last 8 or 10 recent search strings are shown. So preferably this is improved so that for example any number of recent search file names is shown, for example since the word processor was opened in this session, or for example up to a larger number, for example up to 100 names or any other reasonable limit, and/or for example up to N days ago, in which case preferably this list is saved externally so that the word processor can use it also after the program is closed and reopened.   4. Preferably the word processing program behaves consistently with cut &amp; paste where Internet pages are involved, so that for example images are kept properly as an internal part of the document (preferably including also any internet links that the images are pointing to), just as if they were included out of a file for example. For example the way Microsoft Word currently behaves is that if you save a remote Internet page by cut &amp; paste (such as for example http://news.google.com) then the images don&#39;t show up at all. On the other hand, if you first save the page locally and then use cut &amp; paste then the images do show up, however they are linked to the local directory where the images were saved, so if the user for example later sends the same Word file to someone else then the images are again missing when that someone else opens the file. (This same problem happens also if the page that was saved locally is properly opened by Word as a local web page and for example is then saved as a Word document). This is inconsistent with the behavior of other images, which become an integral part of the file. so this is preferably solved as follows: If the links are to local images then preferably they are automatically inserted into the document file itself, and if they are based on links to the actual Internet then preferably they are also included internally in the document and/or they can also be saved as links (preferably the user is asked which these options he/she prefers).   5. Preferably the word processing program (or other programs that deal with opening files, such as for example other Office programs) remembers automatically for example in the “Open file” dialogue box and/or in the “Save” dialogue box if the user typed last time a filename (or path) in English or in another language (for example Hebrew) and preferably leaves this as the default for the next time, which means that this should not be affected if the user for example opens a file that contains Hebrew inside it of for example switches to work in Hebrew within the file. This is very important since it can be very aggravating if the program for example insists each time to start the dialogue box in Hebrew for saving or for opening a file (for example when the user wants to save the file with an incrementing number) even though the user wants each time to type a name in English (which typically happens in the prior art for example if the text of the documents itself is Hebrew, but this does not make sense since having a file that contains Hebrew does not mean that the user necessarily wants to save it under a Hebrew name, especially for example if the user tries each time indeed to save the file with an English file name). Preferably this default is remembered of course also after closing and re-opening the word processor (for example by saving it automatically in some preferably small configuration file). Similarly preferably when the user opens a new file preferably the word processor automatically moves to the language in which most of the opened file is written (For this preferably the word processor simply counts for example the number of words or letters in each language, so that for example if the file is mostly Hebrew preferably after opening the file the word processor automatically expects to get new input in Hebrew) or for example in the language which the user used when working on it the last time, which means that preferably the word processor saves this info in some variable preferably in the file itself. (In the prior art, since Word for example changes its language within the normal text according to the language of the file name, if the user for example has Hebrew files which have an English file name, the word processor always enters them waiting initially for input in English instead of in Hebrew). Preferably the word processor also remembers similarly according to the last internal search in which language the user prefers to perform the search within the file. Another problem is that for example if the user changes the language to Hebrew for example while typing text within the document for example in Word 2000 and even in Word 2007, if the user then tries for example through the Open File dialogue box for example to rename a file—the user cannot change the language back to English within the rename text box. So preferably this is improved so that changing back to English for example by pressing the left Alt-Shift or left Alt-Control works preferably in any place where text can be entered, including for example the Rename box. Another possible variation is that preferably the word processor and/or other applications and/or the dialogue box for example remembers and displays automatically the last requested file pattern when the user tries to open a new file (for example ‘f:\pats\betwin*13*’) and for example if the user for example enters new input—instead of for example pressing enter (to use this pattern) or for example using the arrows and making changes—then the pattern is removed, instead of the prior art, where the input line is empty and the user has to search in a scroll list to find previous search patterns. Another problem is that if the user for example wants to save a web page (for example by pressing Control-S) and tries by mistake to save the same page twice, the user has to press once “No” to the question of if to overwrite the existing file, and only then press Escape to close the save-file dialogue box. So this is preferably improved so that the user can simply press Esc also instead of the “No”, and so the user can for example simply press Esc twice in order to cancel the save. In addition, if a file with the same name already exists in the target directory, preferably the browser checks also if it was saved a very short time ago (for example within minutes) or for example a few days or weeks ago, and for example if it is more then a few minutes ago (or for example if it is not from the same day) preferably checks also to see if the saved file and the current file are identical (for example by size and/or text comparison and/or by checking first of all if it was saved from the same URL) and preferably advises the user automatically if it is the same name but a different file (and as explained elsewhere in this application, preferably the browser automatically includes also the url when saving files, preferably in some comment, preferably at or near the beginning of the page, which is preferably ignored by the browser when displaying the page). Another problem is that for example when the user tries to save locally on his computer a web page, for example Opera and MSIE offer the user as the default file name the title of the web page (i.e. the text which appears at the header section of the web page between &lt;title&gt; . . . &lt;/title&gt; and typically shows at the blue top header of the window)—which is good heuristic in general and much better than Firefox (which offers by default only the local file name at the url, even without the http address, which is much less informative), but still sometimes it is not good enough because for example with some news items the title might be too short and/or uninformative while the visible title of the article itself (which is visible typically at the top of the main column in the web page itself) is more informative. So preferably this is improved so that if the user tries to save a web page locally, the browser preferably checks also the visible title and preferably selects for this the largest text preferably at the top of the main column (which will typically be marked for example within &lt;h1&gt; . . . &lt;/h1&gt; or &lt;h2&gt; . . . &lt;/h2&gt;), and preferably compares this with the text of the above-described text of the &lt;title&gt; section and preferably at least in cases where the text of the &lt;title&gt; contains much less words than the visible title or for example less than some minimal threshold (or for example if a file name with the same title tag string already exists but is for example clearly not the same file, as determined for example by automatic analysis and/or comparison of size and/or content, and/or for example by comparing the visible title or titles between the two files), preferably the browser offers instead as default file name the visible title or for example a combination of both titles (preferably by appending the visible title after the header title or vice versa, for example with some separator between them, such as for example ‘-’). Similarly, when saving for example pdf files the browser preferably offers as default file name the title of the pdf itself (which is preferably identified automatically at least in pdf text files for example by finding the largest text of more than 2 words which appears typically at the beginning of the text or near there), since in pdf files there is no &lt;title&gt; . . . &lt;title&gt; text. Another possible variation is that for example the url itself is automatically also added for example to the suggested file name (for example before or after the title), but this is less preferable since it can become an annoyingly long partially meaningless file name, so preferably the url is preferably automatically added to the saved file, preferably at the beginning of the text, for example as a visible text or within an invisible comment, as explained elsewhere in this application (and if for example the pdf format does not enable an invisible comment that preferably it is added to the format). Preferably these rules are applied also for example when sending a link to a web page by email, since the subject of the email is also generated for example by Opera only according to the header title, so the above or similar rules are preferably also applied for sending a link or web page by email. Of course similar rules can be applied also to other types of non-html files that exist or might exist in the future. Similarly, if the user tries to save for example a newsgroup message (for example through groups.google.com or through a newsgroups client) preferably the browser or other newsgroup client preferably automatically suggests as file name preferably the subject field of the message (and/or for example preferably automatically adds to the suggested file name for example also the newsgroup and/or the date and/or for example the sender&#39;s email. In addition, preferably similar rules are applied for example when saving a bookmark, or for example the main visible title (or for example even additional titles or even all the titles in the text of the web page) is preferably added automatically to the name of the bookmark and/or to the suggested file name when saving the web page preferably always, preferably in addition to the top window title, which means that preferably the user can search for bookmarks with additional keywords (i.e. this is preferably done in general when saving a web page or saving a bookmark for it, at least if the header title and the visible title are not the same, so that preferably the browser automatically combines them, preferably both when saving the file and when saving a bookmark, since this way the file name or the bookmark contain more information about the subject of the web page and can make it easier to find it later). As explained above, the visible titles are preferably identified automatically for example by finding the largest text of more than 2 words which appears typically at the beginning of the text or near there (or also in other places, if more titles are automatically identified). Larger text can be identified for example in html documents for example by finding header tags (typically marked for example by &lt;h1&gt; and ending with &lt;/h1&gt;, or other numbers after the ‘h’), or by finding font size tags which increase the size of a certain section (typically for example a sentence) more than the size of surrounding text. Another possible variation is that if the user for example saves a bookmark of a page and adds something to the suggested name or changes it and then saves the page, or vice versa (i.e. for example first saves the page and then bookmarks it), or for example does this in an email subject when emailing the page or a link to the page and then also saves the page and/or a bookmark, preferably the browser remembers automatically the corrected name and preferably offers it automatically also for the saving of the page or for the bookmarking of it or for the subject of the email. Another possible variation is that preferably similar rules are used for example by the search engine, such as for example Google, so that preferably for example at least if there is no header title in a web page which appears in the results or for example at least if the header title is shorter or considerably shorter than the visible title, then preferably the search result from that page is preferably automatically shown by the search engine with the visible title in addition or instead of the header title. Another possible variation is that if the user for example tries to bookmark a url which he/she already bookmarked, for example a few minutes or seconds ago (which happens many times if the user is not sure if he/she already pressed for example ̂d), preferably the browser automatically ignores the redundant additional bookmark, at least for example if it is also the last bookmark which was saved and/or for example the browser asks the user for confirmation if he/she wants another bookmark of this url even though he/she already made one). Another possible variation is that preferably if the automatically suggested file name contains characters which are invalid for a file name (such as for example “?” or “:”) then preferably the browser or for example the save-file dialogue box preferably automatically removes such characters or for example converts them automatically to acceptable characters, for example according to a set of default rules (actually Opera 9.02 already does this automatic correction in this case—when suggesting automatically a file name), however preferably this is done for example also if the user himself/herself types in such a name or for example cuts and pastes it. Another possible variation is that preferably the browser offers as one of the options for example pressing a special control which at the same time activates both saving a bookmark and saving the web page itself (which has the further advantage that if the user for example wants to change something in the suggested name it is done automatically for both of them at the same time). Another possible variation is that preferably the browser automatically recommends to the user to also save a copy of the page itself when the user saves a bookmark—at least for example when this is a news site, since typically at least some news sites make a news item inaccessible after a few months or less or for example put it in an archive and charge money for accessing it later. Preferably the browser can for example identify the site as an online news source for example by keeping some automatic intelligent track of how the user got there—for example if the user got there by clicking on a link in Google News or by clicking on a link in an email sent by Google News alerts, and/or for example by accessing some relevant database or databases, and/or for example by performing automatically for example at least once a month (or other reasonable period) a number of automatic searches for example in Google News in a way that can automatically reveal updates in the news sources covered, and/or for example by automatic analysis of the web page according to various patterns that can indicate that this is a news source. Another possible variation is that for example when the user saves the page the browser for example automatically adds also for example the domain or the url to the name and/or at least for example keeps it for example in the file itself, for example in a visible place or within for example an html tag which is not normally displayed. Another possible variation is that preferably when saving the file Preferably when saving the file the browser Another possible variation is that preferably when the user sends email (for example by composing a new email message or by sending a web page as a link), preferably the browser enters automatically by default the recipient or recipients of the last email which the user sent (since typically many times the user sends email repeatedly to a small number of recurring recipients), and for example if the user starts typing something else on top of the first recipient (or replaces it by choosing from a pop-up menu of fitting addresses that is updated after each letter, as is done for example in Opera) then preferably this or all of the other automatically pre-assigned recipients are preferably automatically removed by the browser and so preferably only the newly entered recipients become relevant. Another problem is that when saving for example web pages for example the Opera browser by default saves only the text without images, which is very efficient, but this means that when the user views the saved web page only images which had a full http address within the web page are displayed. So preferably this is improved so that preferably the browser (or for example some other program or for example plug-in) (for example if the user enables this feature but preferably by default) preferably automatically converts local addresses of images (i.e. without a full http address) to full http links preferably by taking into account the url of the web page and/or any relevant html command such as for example “base href” (i.e. for example the browser automatically adds the url to internal links and/or for example automatically adds a “base href” command), which is done preferably at the time of saving the file or for example at the time of opening it locally (but in this case preferably the url is also saved automatically by the browser, preferably within the saved web page, as explained above), so that preferably if the user then opens the saved web page locally with an open internet connection and the original images still exist on the web site then the browser can automatically display images that would not be visible if the images with the local relative addresses has not been converted as explained above. Another possible variation is that for example when displaying the list of bookmarks preferably the browser displays automatically also the url for example at least if there are for example entries next to each other or not far from each other (i.e. for example visible at the same viewable section of the bookmarks) which have the same title but not an identical url (which would happen for example if the user bookmarks for a number of pages in a web site but they all have the same title for example in the header field), but saving automatically also the visible title as explained above is of course more preferable. Another problem is that if the user tries to send someone by email a link to an open web page or tab which is actually a previously locally saved copy and the user does not pay attention to this, then the link becomes a local link which is useless to the receiver. So preferably this is improved so that in such cases preferably the browser automatically reminds the user that the link is local and/or for example preferably suggests to the user automatically to send an attachment of the actual local file instead of the link, and/or for example automatically offers the user to insert instead the original url (for example by identifying the original url from the contents the locally saved page or for example from a an explicitly saved address, since as explained elsewhere in this application preferably the browser saves automatically also the url of each page when saving it locally, for example within a non-visible comment). And in such case preferably the browser allso oofer sthe user automatically to go first to the original url agai nbefore4 sending the link, in prdr tpo voe w again page at the original url in ord to make sure for example that it still exists or that it has not changed) Another problem is that if for example Word and/or Windows crashes, the next time that the user opens the word processor he/she is typically given the option to re-edit an automatically saved copy of the files that were open before the crash, but if he/she closes them he/she cannot automatically regain access to them, even if for example he/she later finds out that he/she does indeed need one or more of them. So preferably the word processor is improved so that even after the user closes those automatically offered files or tells the word processor to discard them, he/she can preferably still activate an option that restores them, preferably even if the user in the meantime closes the word processor and then later reopens it. For this preferably the word processor keeps one or more buffers which point to these automatically saved files and preferably has an indication which groups of files belong together and/or to which crash event they are related, and preferably these files are kept in the original directories of the relevant files (and/or for example in a special directory) for example at least for a certain time period and/or for example as long as there is sufficient disk space and/or for example until their cumulative total space exceeds some value (and then preferably the oldest files are deleted if needed). In addition, since many times the user does not know if he/she needs the automatically offered files, another possible variation is that preferably the word processor automatically runs file comparison between each such file and the equivalent last saved version and preferably shows the user by track changes the differences between this and the saved version, and preferably if there are no differences then the word processor automatically does not even offer that file. When showing automatically the differences, preferably the word processor marks them differently (for example by a different color even if the 2 files for example already contain marked changes), and preferably the word processor automatically indicates the amount of difference (for example in terms of number of letters and/or words and/or sentences and/or sections changed), and preferably the word processor can let the user jump automatically to those sections where the changes are. This is important since in the prior art most of the times the user assumes that he/she saved whatever was important and so usually ignores the offered files. In addition, if the user decides that it is indeed important to save these changes then preferably the user can for example tell the word processor to automatically add them to the last saved version (for example by renaming or copying the relevant automatically saved file over the last version saved by the user), or for example the word processor can automatically increment by 1 the file name and save it there (for example by renaming the automatically saved file to the new name). Another problem is that when the user for example wants to open a file or use “save-as” for example in Word 2003 or Word 2007 on windows XP it usually takes quite a long time till the dialogue box shows the available files in the directory (at least if there are many files and/or subdirectories in the current default directory), even if this is done for example just a few seconds after the previous access to the dialogue box. So this is preferably improved so that this is done preferably instantaneously or almost instantaneously. Preferably this is done for example by saving automatically the structure of the current directory in one or more buffer in memory (and/or even in the disk)(preferably in the same sorted order in which it is displayed), and preferably the OS automatically updates this buffer in memory (and/or on the disk) for example even if some other process which is running at the same time for example changes something in that directory. Preferably this is done for example automatically for any directory recently accessed by the dialogue box, and/or for example the word processor (and/or other applications) can preferably tell the OS already for example when they are activated to prepare the buffer of their current default directory in memory, and/or for example any directories are automatically saved also in the sorted order (For example the OS keeps for each directory or at least for many directories automatically also a sorted copy of the file names and/or sub-directory and/or for example an index or for example hash table of file names, and/or for example the instant desktop search is also integrated for example with the dialogue box, so that preferably when opening a file or when saving with the “save as” option preferably the directory is displayed preferably instantly preferably as the user types, like in the normal instant desktop search, except that this is preferably automatically limited to the scope of the current directory and preferably refers automatically only to file names and not to text within them. This is preferably done for example by the desktop search automatically keeping the file names of each directory for example in a separate index or indexes that are preferably automatically made available for example to the open file or save file dialogue box. In this case preferably either no files names are displayed until the user starts typing or for example all the file names are preferably instantly displayed when the user opens the dialogue box but are quickly reduced to only matching file names as the user starts typing. This is good anyway since it can serve also as another backup of the directory table). In addition, preferably any changes in file names and/or additions and/or deletions of files are preferably automatically updated for example in the buffer by simply merging them with the already sorted directory, instead of re-sorting it again each time. Similarly, another possible variation is that for example the indexed desktop search (such as for example Google desktop search or for example the similar feature supplied by Windows Vista) is preferably interfaced or integrated for example also for example with the normal dir function of DOS or CMD windows, so that for example, especially if it is a large directory, if the user for example types ‘dir’ with or without a specific search pattern, preferably the list of file names and/or directories is preferably supplied preferably instantly from the element in the indexed desktop search which has information about indexed file names and subdirectories in the relevant directory or directories. What is even more annoying in the dialogue box of Word 2003 is that when there are many files in the directory (for example a few thousands), while it is scanning the directory, the dialogue box appears to be stuck and may not even show the user what he/she is typing in the input line until for example 5-10 seconds later, and during this time the user doesn&#39;t even know if what he/she is trying to type will even be accepted. So preferably this is improved so that the dialogue box samples more frequently what the user is typing and preferably displays it immediately. In addition, preferably the dialogue box monitors all the time the user&#39;s input line and/or preferably for example when the user starts typing something preferably the dialogue box for example waits for the user to finish before starting for example to search and sort the file names that fit the pattern or for example displays instant indexed results as the user types, as explained above, and/or preferably at least the open-file the dialogue box preferably does not even start searching for file names until the user starts typing unless for example the user does not start typing for a certain time, such as for example a second or other reasonable period (since it is very rare that the user want search for a specific pattern) and for example if the user starts typing the path to another directory (for example typing a “\” at the beginning of the line followed by one or more letters which are different from the current path) then preferably any scanning or sorting of files in the current directory is preferably immediately aborted. Another possible variation is that if the user types for example 2 or more words, preferably the desktop search also searches for example for file names in which the two words are without a space between them, at least for example if there is a capital letter at the beginning of each word. Another possible variation is that preferably when the list of recently opened files is displayed for example in the Word processor preferably the user can for example mark more than one such file at the same time and for example automatically open all of the marked files for example into new windows or new tabs. Another possible variation is that preferably the word processor or for example the dialogue box can also keep more than one default directory (for example according to recency and/or frequency of use) and so for example when the user starts typing a file name to open preferably the list of most likely paths is preferably shown near it, for example as a pull down menu which the user can choose from if he/she wishes. Another problem with the dialogue box is that for example in Microsoft Word (including Word 2003) when the dialogue box is open (for example for opening a file or saving a file), if the user tries to jumps to another open Word window, the box of the other window on the task bar seems to be activated but in practice the open dialogue box still remains in front and the user still remains in the original Word window, which can be both confusing and annoying, especially for example if the user is trying to look for example at the file name of the other window in order to decide what to answer to the dialogue box. So preferably this is improved so that the dialogue box is linked only to the Window from which it was opened, so that when the user open a dialogue box from one Word window preferably the user can jump to other Word windows just like he/she can jump to windows of applications even while the dialogue box is still open, and preferably each Word window can have its own dialogue box open even at the same time independently of other Word windows. Similarly, for example in the Opera browser, if the dialog box is open the user cannot at all jump again to the tab from which it was opened or to any other tabs (eventhough the user apparently can jump to other Opera windows with no problem) until the dialogue box is closed. So preferably this is improved so that opening the dialogue box does not prevent the user from returning to the original tab from which it was opened or to other tabs, and if the user does that then preferably the dialogue open box becomes accessible again for example through a special icon or for example the open dialogue box becomes accessible though a special handle like the other tabs (so that preferably when that icon or handle is clicked the user is returned to the last tab from which it was opened and the open dialog box shows on top of that tab) or through reopening the dialogue box. Another problem is that for example in Word (both Word 2000 and even Word 2003 and Word 2007), when the user searches for a word or string and the string requires jumping to a new page (i.e. is not within the current text that is already shown on the screen), the word processor always displays the line with the found text on the top line of the screen, which is not efficient since it prevents the user from seeing better the context, and if the user for example wants to see also for example 2-3 lines before the found string then he/she has to scroll backwards. So preferably this is improved so that the found text is automatically shown by default for example with at least 1 or more previous lines on the same screen, and/or preferably the user can easily change the default position, for example through an option in the search menu, and/or or for example if the user scrolls back for example 1 or 2 or more lines after a string is found and shown, preferably the word processor learns this automatically and adds automatically 1 or 2 or more previous lines when a string is found and shown on text that was not previously on the screen. These principles can be used of course also in other applications, such as for example when searching for strings for example in documents displayed by the web browser or for example when searching in pdf documents or other formats, etc.   6. Preferably the user can use for example ̂Z (Control-z) (or other similar commands) to undo the last changes even after closing and reopening a file, unlike the prior art, in which this can only be done as long as the file remains open. This is preferably done either by saving the undo data in the file itself, or (more preferably) by saving it preferably in another local file, so that the original file preferably only contains a link to the associated local undo file (preferably this saving is done also automatically and not only when the user saves the file, for example preferably based on time interval and/or on the amount of changes, so that this can work also after a crash). This has the advantage that when sending for example the file to someone else the previous versions and last changes are not transmitted together with that file to the other person, and yet the original user has flexibility to use the undo even after the file was already closed, as explained above. In this case preferably the system indicates to the user when he/she is about to undo things to a state before the last saved version of the file and preferably asks for his/her confirmation for that. (This means of course that this feature can also be used for example for merely returning after reopen to the last position which the user was editing before the file was closed, for example by using the control for Undo and immediately afterward Redo). Another possible variation is that for example after a crash or even after normally closing a file, preferably when reopening it the user is given an option to jump back to the last position that he/she edited even if Undo at this stage is not available, which means that preferably only for example the offset of the last editing position is preferably automatically saved in this case. Another possible variation is that if the user for example makes some changes on a file and saves it and then remembers that he/she prefers to save the changes only in a separate new file, preferably by pressing for example ̂Z until all the new changes since the last open have been undone preferably if the user then saves the file again, the word processor preferably automatically restores the original time and date of the file. Of course when the user repeatedly presses for example ̂Z and reaches the state where the file was at the condition it was last opened preferably the normal ̂Z does not continue before preferably presenting to the user a warning that additional ‘undo’s will now go back to a previous state of the file before the version that was currently opened and/or for example a separate control is needed to go back beyond this point, in order to prevent the user from accidentally returning the file to an older state which the user did not intend to. Another possible variation is that for example the word processor or browser or other application can keep in memory different search strings in different open windows of the same application (and especially for example if some are for example in English and some are in for example in Hebrew or some other language), so that for example the user indicates if he/she prefers sharing search strings between the open Windows or having one for all. Another possible variation is that for example the word processor or browser or other application (for example pdf viewers) can remember the last search strings or search strings that were used the pervious time one or more windows of the application were open (for example by saving it in some configuration file or other file on the disk), and preferably lets the user choose automatically the last search string or for example chose from a group of recent search strings. Another possible variation is that for example after the user makes changes in a certain position in a document which causes jumping there (for example presses ̂Z and then ̂Y) preferably he/she can also jump back to the position he/she was before the jump and/or for example if the user changes something in a certain area in the document and then jumps to another area and changes something there and forgets where he was before, preferably he/she can automatically jump back there without having to undo the last change. This can be done for example by a command which for example keeps a list of the most recently areas of the document in which the user was working, so that for example pressing some key (for example ̂j) or choosing the appropriate option in a menu) causes the user to jump back to the previous area he/she was working on (and preferably pressing again the control makes the user jump to a previous area, so that preferably each jump bring the user to the previous non-consecutive area which he/she edited or jumped to for example by page up or down or through search, without having to undo anything in order to jump to the previous area), and/or for example open a pull down list which shows the relevant sections for example each in one or more lines and/or show preview windows and the user can click on the desired choice. Another possible variation is that when copying text for example by copy &amp; paste into an empty new file preferably the headers (for example containing author name, date and page numbers, etc.) are automatically inserted into the new file and/or for example other file parameters are also copied automatically. Preferably the headers and/or other parameters are copied automatically but the user preferably can also choose for example to disable this feature or for example to disable parts of it. Another possible variation is that for example copy &amp; paste and/or for example print and/or save are automatically available from any messages (including for example any application window or area on the screen) displayed on the screen (This can be accomplished for example by supplying standard communication tools that support this to various software, and/or for example the OS or for example some special application automatically allows the user to copy and paste and/or print for example from any text that appears on the screen, regardless of which program it belongs to, preferably by being able to locate any text on the screen or in any application, and/or for example automatically applying OCR for example in case the text is graphic). Another possible variation is that preferably the user can also for example print anything from the screen directly to the printer—for example by using a right mouse button menu to mark the desired area for printing and/or for example to choose the printer, so that for example this direct printing optioned is access through the right-mouse button menu and/or for example pressing print screen brings up a box that allows the user to choose for example between normal copy into the clipboard and printing directly from the screen. This can be much more efficient than the prior art, where in order to print the graphic contents of the screen the user needs to use print-screen in order to copy the image to the clipboard and then has to enter a drawing program and paste back the image into it and then print it from the drawing program.   7. Preferably the word processor program allows the user also options of searching and/or substituting for example based on style (including of course for example text color and/or background color and/or underline and/or boldface and/or italics and/or font type and/or any other feature) and/or shape and/or size instead of just character strings, so that for example the user can request to find the next underlined word (or words or section), or for example the next words that are in italics or for example to jump to the next marked change (when changes were marked for example by using the “track changes” feature or the file comparison feature, for example any marked change in general or for example only changes of a specific author or color or for example date range and/or for example the next added text and/or for example the next area of text which is marked as deleted and/or for example text which was moved, etc.—for example in general or in combination with searching for a specific search string) or for example jump to the next word marked as possible error (for example to any type of error or for example separately to errors marked in red—which are typically typing errors, i.e. words that the word processor thinks that they don&#39;ts exist, or possible errors of other types which are typically marked for example in green (preferably there is for example also a specific control key combination for each of these options) or for example request to automatically convert all the words that are in italics to underline or vice versa, or for example to automatically convert all fonts of size 13 to size 14 for example without affecting other font sizes, or for example to increase automatically all the font sizes by a certain additive or multiplicatory factor (so that for example each font size will increase by 1 pixel), or for example to convert one or more word to another word or words and define that the new word or words will for example be marked by underline and/or other style and/or shape and/or size in each occurrence that is thus substituted, etc. (Preferably in order to enable the user to easily indicate that he/she wants for example to search or substitute something for example only within the purple marked changes or for example within a certain date range, preferably the search dialogue box contains automatically mark-able colors and/or changeable dates preferably near the Search and Substitute fields and/or the user can for example ad to the search and/or substitute field one or more control words or characters which indicate this). (Although when activating the “accept changes option” Word for example allows the user to jump to the next marked change, this is much less convenient and for example marks the found change in black block, and the user has to click on a number of menu options to reach this, whereas it would be much more convenient if it became a standard available search option like any other search, so that the user can preferably also afterwards for example simply jump to the next such text preferably by a 1-key or 2-key command, for example by simply pressing Ctrl-PgDn, like in other repeat-searches). Of course preferably this can also be combined, so that for example after normal search the user can preferably with a single click or key request also to accept or reject the change, and/or for example after using the search of the accept/reject window preferably the user can close the window and continue searching for the next section (for example by simply pressing Ctrl-PgDn, like in other repeat-searches). Another problem is that for example when the user searches for a letter preceded by a “̂” in Word (for example ̂S or ̂N or ̂T), the word processor for some reason is unable to find them. So preferably this is improved of course so that the word processor can regard this search string as normal text and find it normally. Another problem is that for example when added text is marked in track changes it is always underlined, so the user cannot know when the text or part of it also contains a normal underline (which will become visible only after the user accepts the change). So preferably this is improved so that when text marked with track changes is also underlined, preferably for example an additional preferably thin underline is added (for example below or above the original underline of the track changes), and/or for example the underline becomes in a different color from the text to which it is coupled, and/or for example there is still only one underline but it becomes for example thicker and/or for example moves up or down at the area of the underlined text, or for example becomes with a different pattern (or for example even becomes split into two very thin lines in the place of the original line), and/or for example some other visual indication of the underline is given. Another possible variation is that the fact that the text is underlined is shown or indicated for example only when the user hovers with the mouse over the underlined text, but that is less preferable. Similarly, there is a problem that for example if there is a web link (for example http://something.com) within an added text which is marked by track changes, the user does not know for example if it will look properly marked in blue and underline (as the typical link color) after the marking of the tracked changes is removed. So preferably this is improved so that there is preferably at least some visual indication of the preferably blue color of the link, preferably without destroying the indication that it is also added text, such as for example by displaying the text with double colors, so that for example the outlines of the character in the link shown both in the color of the change and in blue (for example by duplicating each line of the outline, as if drawn for example by 2 pencils with two different color, held very close to each other during the drawing, or for example the characters of the link are displayed blue in their lower half and with the color of the marked text on their upper half, or vice versa, or for example the character of the links are shown in blue but are underlined by the color of the tracked changes, or for example vice versa—the characters remain with the color of the tracked changes but have a blue underline, or other combinations), and/or for example a blur underline is automatically added for example below the normal underline of the track changes. Similarly, if the user for example compares two files in which one or both contain already marked changes and one or more of these previously marked changes need to be marked as a changed also in the comparison file, then marking such text in the color of the present changes would fail to show that it was marked before, and leaving it in the original color would fail to show that it is also for example new next in the new merged file. So preferably this is improved so that in such cases preferably both colors are shown for such text, for example by any of the above described means of showing two separate color for the same text at the same time, and/or for example the user can preferably choose for example from a number of possible default options about how to display such text. Another problem is that when searching for the next change if for example a paragraph number has changed, word marks in black the entire paragraph even though just the number has changed, so preferably this is improved so that only the changed number is marked. In addition, at least when normally searching for text marked by track changes, preferably the word processor does not mark the changed section in black (since that makes it much harder to read) but preferably simply jumps preferably to its beginning, since it is of course sufficiently marked anyway. Another possible variation (which can be used for example for any situations where marked sections are used) is that the user can for example preferably easily define or chose from a number of available options how marked text for example in general will be shown (for example with a preferably slightly different background and/or different foreground color and/or other visually convenient ways instead of inversing it). Of course, preferably this can also be used in combination with other search criteria, so that for example the user can preferably search for example for a specific text which has one or more such specific attributes, such as for example search for all instances of the word “drivers” in which the word is marked as deleted, or for example in which the word is marked as newly added, etc. Of course these additional search options can be very easily supported by the word processor since these text areas have these attributes marked anyway. Another possible variation is that for example when searching for word combinations the word processor preferably has an option of automatically ignoring redundant spaces (for example if there are 2 or more spaces between two words instead of one space) for example by user&#39;s choice or more preferably by default, and/or for example offering automatically also results with a dash between 2 words instead of a space or vice versa, and/or for example offering also results where for example two adjacent search words appear as a single word, and/or for example offering automatically also results with another order of the search words, and/or offering automatically also “Near” search, as explained elsewhere in this application. Preferably the word processor by default offers this option automatically unless the user sets it to look only for the exact amount of spaces between words. Another problem is that when the user for example tries to make a repeated change in Word but confirm it at each step (instead of just global change), the position of the search-and-replace dialogue box many times changes (in cases where otherwise it would cover the relevant text), which forces the user to move the mouse to the new position instead of just keeping his/her hand at the same place and just pressing the Replace or Find-next buttons. So preferably instead, either the position of the search-and-replace dialogue box is always kept constant and the text itself is automatically always scrolled so that the relevant part is visible, or if the position of the search-and-replace dialogue box does move, preferably the mouse cursor automatically jumps with it, so the user does not have to move the mouse to correct for the change in the position of the search-and-replace dialogue box. Another problem with the search and replace dialogue box is that even for example in Word 2003 the text length that can be entered into this dialogue box is limited to about 3½ lines. So preferably this is improved so that there is preferably no such limitation or at least the limit is much larger, such as for example whole paragraphs or even a length of a full page or even multiple pages. Another possible variation is that the user can mark one or more areas in the file and activate the “accept changes” command and then the “accept changes” (for example accept ALL changes) or “reject changes” can be automatically done only in the marked areas (preferably with or without verify). Another possible variation is that when there are for example different sets of marked changes (for example according to the time or file version in which the set of changes was made, and/or according to the source of the changes), preferably the user can for example instruct the word processor to automatically accept all the changes but only for example from a certain date or dates or a certain source or sources. For this preferably the word processor automatically shows the user a menu of the available options and allows him/her to choose for example by marking one or more of the desired options. Another possible variation is to include in the search also logical paragraph numbering, so that the user can for example search for a clause that starts with an automatically numbered letter or number (for example “a.” or “35.”). Another possible variation is to allow the user for example to automatically reformat all the logically numbered paragraphs and/or for example to use a certain constant indentation factor without having to mark them, so that for example in patent claims (numbered automatically with numbers, in which some of the claims contain for example sub-clauses marked automatically by letters), the user does not have to mark and move the sub-clauses for each claim separately (as he would have to do in the prior art, since marking for example all the claims together would change both the clauses and the sub clauses to the same indentation) but can for example change some global definition that automatically affects each type of automatically numbered element or for example affects all of them only in the marked section (for example all the claims)—for example a definition for all the 1 st  level clauses, a definition for all the 2 nd  degree sub-clauses, etc., or for example the user can define general indentation rules, so that for example for each sub-level the indentation is defined for example as 3 more characters to the right, than the previous level, etc. Similarly, preferably the user can also preferably easily define other rules which apply to all similar structures (preferably by defining an example or choosing for example from general rules), so that for example the user can easily define that in structures such as patent claims each sub-clause within a claim will automatically end for example with a “;” and only the last sub-clause will automatically end with a “.”, etc. Similarly, when the user changes for example the left margin of the document (in left-to-right languages, and/or for example the right margin in right-to left languages), for example for the entire document or for one or more marked sections by moving the border on the ruler. preferably the entire structure of the paragraphs is moved right or left without changes in the structure itself (so that for example the same indentations remain for the beginning of paragraphs and/or for clauses and/or automatically numbered clauses, etc.). This is better than the prior art, in which changing the margin this way for example in Word causes the internal relations within the structures to change, since in most case when the user wants smaller or larger margins he/she does not intend to change any structures. On the other hand, if this is enabled, preferably there remains also an additional preferably separate command which the user can use in the unlikely case/that he/she indeed does wants for example to collapse all the structures within the marked area to start at exactly the same place, thus changing the internal relations. Actually Word does allow this but only from the “Page setup” submenu of the “File” menu (which is less intuitive and takes time to discover), but it is page oriented, so that if the user for example changes this way the left margin of a selected section, the selected section is forced to become alone on a separate page, which can be very annoying if the user only wanted to change its margin without moving it to a separate page, broken from the text before and after it. So preferably this becomes available directly also for example when merely marking a section and moving the left edge of it (for example in English or for right for example in Hebrew) on the ruler, and preferably no page breaks are added there unless the user requests them explicitly. This has the additional advantage that the margins can be moved directly visually and intuitively instead of specifying a distance in numbers. Preferably for example the normal triangle on the ruler keeps, at least by default, the internal indentation when moving the margin, and for example the user can change this default or for example an additional separate marker can be dragged in order to change the margin in a way that destroys the original internal indentations, or for example when dragging the left triangle in English (or right one in Hebrew, etc.) an automatic submenu preferably appears which asks the user if the keep the internal indentation relations within the dragged section or destroy it. Another preferable variation is that the user can for example mark one or more sections (for example with the mouse) and then for example toggle automatically between modes so that for example automatic numbers and/or letters can become manual letters and/or numbers and vice versa (for example in the CLAIMS section of a patent). This is much better than the prior art, where the user has to manually convert each number or letter one at a time from automatic mode to real numbers and letters one after the other, or vice versa. The word processor can do this very easily for example by simply changing the attributes of the relevant text and adding the appropriate characters or vice versa. (Of course, a conversion from automatic to real numbers and/or letters can be done for example by saving the Word document as a text file, but that is much less convenient and has other disadvantages because it entails losing other format features).   8. In the prior art Microsoft Word, deleting the “Enter” between two paragraphs can cause for example the first paragraph to change automatically its font (for example become bigger or smaller or a different font or in a different style) for example according to some qualities of the empty line that was deleted between the paragraphs or some other reason. Since obviously at least in most cases the user does not intend to create such changes by merely deleting an empty line between two paragraphs, preferably no such changes are created automatically. Preferably fonts and/or style are automatically changed for example only in the 2 nd  paragraphs after connecting it with the 1 st  paragraph (and in this case preferably to become like in the first paragraph and not like some empty line in between them), and even that is preferably not done automatically but only if the user allows this by default or requests this specifically for example by pressing some key or some button. A similar problem is that for example in Word 2000 and even in Word 2007 beta 2, many times when the user presses “Enter” and continues to type, the font suddenly changes to some other default instead of continuing with the same font and style and size of the previous paragraph, and the only way the user can overcome this is by adding at least one character in front of the cursor before pressing the “Enter”. So this is preferably improved so that the font and/or style do not change when pressing “enter” or at least not if the user continues to type at that position immediately or within short time period, unless the user requests this explicitly.   9. Another problem with word processors such as for example Word, is that URL links (typically Internet links) (for example http://www.opnix.com/products_services/orbit1000/Middle_Mile_Mayhem.pdf) are not treated properly when paragraphs are automatically aligned, so that for example a URL link that is too long can jump to the next line and cause the words in the previous line to become with too many spaces between them (as it happens for example with the above exemplary link), and if the user manually fixes this for example by breaking the URL for example at the position of one of the slashes, this will cause the link not to work properly, and also, if the paragraph is then changed again, the broken part of the link might come back to the previous line, thus causing the link to appear as if there is a space between the two parts. On the other hand, if the link is too long to fit even an independent line, it is currently broken by Word at the last character that fits the line (as happens in the above exemplary link), instead of breaking it more smartly, preferably according to the closest slash. So preferably this is improved, so that links are preferably automatically and dynamically broken and restored between the lines as the paragraph changes, preferably according to slashes (and/or for example sometimes underlines and/or dots and/or question marks and/or other special characters), and preferably when the user presses the link, it is treated as one consecutive link regardless of this automatically changing break between the lines. Similarly, if the link for example occupies almost all of the line (so there is no room for adding any additional word), and the paragraph is block-aligned (i.e. made straight on both sides), since the url typically does not contain spaces, preferably the alignment for example to the right (for example in an English paragraph) (or for example to the left in right-to-left languages) is preferably done in this case by adding automatically for example micro-spaces between letters (an/or for example increasing the length of underlines between words when such underlines exist in the url). Another very serious problem with URL links is that for example if the user copies and pastes a new http link over a previous http link for example in Word, the address appears as if it has been changed, but when the user presses the link he actually gets the original link. So preferably the word processor (or other application) automatically replaces also the internal link to automatically comply with the visible link, or for example saves only the visible link and uses that information when the user tries to access the link, so there is no additional internal link which can become different from the visible link (which is very important also from security considerations). These rules are preferably similarly kept for example also in pdf files, because in the prior art for example if this bug occurs in Word and the file is later saved as pdf, the misleading links carry over also to the pdf file.   10. Another problem is that in large files if the user wants to mark large areas with the mouse (for example from a certain point till the end of the file), he/she must continue to hold the mouse pointer near the bottom of the page with the mouse key pressed, which can be quite annoying. So preferably for example while the mouse key is still pressed (or for example even if the user lets go of it but presses an appropriate command), the user can for example use other location commands, such as for example Control-PageDown or Control-End or for example End or preferably other single key, or search commands, and then preferably the entire area till the next location becomes marked, instead of having to wait for the page to scroll. Another possible variation is that the user can for example simply jump between two places and then press some key (or for example click one of the mouse buttons) which marks the entire block between them, or for example mark one place (for example with the mouse or by pressing some key) and then jump to another place and when reaching the desired destination press some key (or for example a mouse button) and the entire area between the two marks becomes marked. Another possible variation is that for example pressing some key can significantly increase the speed of the scrolling or for example moving the mouse further to a more extreme position significantly increases the speed of the scrolling (preferably this is linear, so that the speed changes gradually according to how extreme the position of the mouse is, but it can also be for example exponential so that for example going the extreme bottom position will almost instantly cause the position to jump to the end of the file). Another possible variation is that if the user already marked a section for example with the mouse and then for example uses the mouse to click on something else and then wants to go back and for example increase or decrease the marked area, he/she can still use the mouse and/or other keys for example to go back and extend or reduce the section without having to start marking again from the beginning. This can be also useful for example if the user first uses for example ̂a to mark the entire file and then for example uses the mouse and/or other keys to reduce the marked section or remove parts of it. Another possible variation is that the user can mark more than one area with the mouse at the same time, for example by pressing some key that tells the application not to remove the mark from the previous marked area or areas. Preferably these options are done for example by pressing some key which tells the word processor (or other application) to keep the previously marked area and add to it and/or for example to automatically restore it if the user clicked on something that already created a new marked area instead of the previous marked area, and then the user can for example increase the marked area or reduce it or for example mark one or more additional sections while the original marked section remains marked. Of course these and/other features can be used also with other types of files and not just in word processing programs, such as for example with Internet browsers, etc.   11. Another important improvement is that preferably the user can for example choose a specific font color and/or for example specific font attribute (for example underline) which preferably is kept automatically until changed again, so that this text preferably appears wherever the user adds it to previous text, regardless of the color or other attributes of the section of the previous text in which the new text in inserted. This is very convenient for example for keeping track of additions (for example when the user does not want to activate the automatic track changes), or for example for adding comments for example in another color. This is in contrast to the prior art, where for example in Word such options must be chosen again in each section, otherwise when the user starts to add text at a different place it automatically assumes the color and attributes of the surrounding text.   12. Another improvement is that preferably the word processor can allow the user to easily define page numbering that starts from a certain value other than 1, for example since page 50 (or any other desired number) since for example sometimes the user might want to print pages that will be attached after other already printed pages as if they are part of the same file. This can be defined for example by letting the user use a formula, so that for example if the current page number is marked for example in Word as “#”, the user can preferably specify for example “#+49”, so the page numbering will start for example from 50 instead of 1, and then preferably for example the total number of pages is automatically updated accordingly even if the user does not enter the formula there too. Another possible variation is that for example when the user enters for example in the top page title for example the # mark, which in Microsoft Word means automatic page number, the system automatically shows for example a scroll window near it with the default of 1 and the user can instantly for example increase the number by scrolling the window or typing a different number there. (Although for example Word allows the user to cause the page numbering to start at a different number, it is done in a much less intuitive way since the user has to go to the “addition” menu, then choose “page numbers”, then go to “Pattern” and then indicate a page number to start from). Another possible variation is that the user can for example change the rules of page numbering in a way that affects for example only the current page or for example a group of marked pages or for example from the current page until another such change is defined or for example for the next N pages, so that for example the user can define the last pages in a patent which contain figures to be automatically renumbered starting from there as 1 and/or for example change other things in the header of these pages without affecting the headers of the rest of the pages. For this preferably the word processor keeps in the saved file information for multiple headers, preferably each set tagged with a beginning page and end page, for example.   13. Another problem is that for example Word sometimes decides to move paragraphs to the next page without any apparent reason, thus leaving sometimes a large empty space in the previous pages. So preferably the user can for example click in any such case for example on the empty space or on the moved paragraph and/or for example enter a command that tells the word processor that the user does not want such empty spaces, and/or for example the user can activate a command that automatically fixes all such unnecessary empty spaces globally and/or prevents them from being created.   14. Another problem is that in Word for example when switching between the Hebrew dictionary to the English dictionary or vice versa, the language in the small window where the checked word is entered does not automatically change in accordance, so many times the user has also to press Alt-Shift in order to switch to the desired language in the small window, which can be very aggravating if the user starts typing and then sees that the language is the wrong language. So preferably this is improved so that switching the dictionary also automatically switches the language correspondingly in the small window or area where the word has to be entered, so that for example if the user switches to Hebrew/English dictionary then the language in the small window preferably automatically becomes Hebrew, and when the user switches to English/Hebrew the language in the small window or area where the word has to be entered preferably automatically becomes English. Another preferable improvement is that when switching language, if the user has already entered a word in the translation window, preferably the word is not automatically erased when the user switches the language. Similarly, if the user for example switches the language in the small window, preferably this can automatically switch the direction of the dictionary accordingly, so that for example if the user types or paste s a Hebrew word the dictionary preferably automatically becomes Hebrew-&gt;English, and vice versa. Another possible improvement is that preferably when using the dictionary the user can use also forward and/or backwards movement (for example by clicking on an appropriate icon or a keyboard key), so that he can go back or forward to previously checked words (in a way similar to browsing a directory or to browsing the Internet). Of course this preferably done with any relevant languages. Another preferable improvement is that the dictionary preferably allows the user to use back arrows in order to go back to previous points in the dictionary for example if the user clicks on various words in a sequence. Another preferable improvement is that when the thesaurus is used preferably the dictionary shows near each newly found word of the thesaurus also its translation to the other language (for example Hebrew) and/or a short description of its more precise meaning in a few words, for example within brackets next to the word, and for example clicking on any of the words or explanation words or the translated words (for example in Hebrew) preferably activates the thesaurus and/or the dictionary again recursively on the clicked word. In addition, preferably the thesaurus and/or the dictionary automatically takes into consideration the context in which the word exists in the file (for example the next few words and/or the sentence and/or the general subject) so that preferably when displaying semantic trees or groups of semantic branches preferably the groups or branches are pre-sorted according to the most likely meaning when taking said context into consideration and/or for example only the most likely meaning branch is shown. Similarly, preferably the automatic typing-error-correction system preferably also takes into account also the context and so preferably chooses the word most likely according to context when there is more than one reasonable correction (and/or for example in cases the system is not sure it preferably shows the user that there is more than one likely correct word and asks him/her to choose the correct one for example by scrolling to the preferred one), since in the prior art many times the automatic error correcting system for example in Word corrects a word which contains a spelling error into a different word which the user didn&#39;t mean at all and then if the user doesn&#39;t notice it the sentence might be perhaps even dangerously wrong. (The context can be for example based on pre-gathered automatic statistics for example from Internet knowledge bases and/or for example specifically from the user&#39;s files and/or for example from the specific file or similar files (for example those that have a similar name or were part of the same project, which preferably the word processors knows automatically by keeping automatically a list of file renaming history), so that for example if the word “windows” appears a lot in the same file or for example in the series of files from which the current file evolved, the word processor preferably gives wrong words that could be “windows” a higher chance for being corrected into this, and so for example the frequency of the word itself in the user&#39;s document or relevant documents and/or the chance of it occurring with the actual next word or words (for example before and/or after it) is preferably also taken into account. Another possible variation is that for example the automatic logging of the evolution of the file name can also be used for example to automatically increment the numbers and/or letters which the user has been incrementing, so that for example the save menu contains an option (which can be called for example “Save next”), which automatically increments the correct element and thus saves the new version in a new file (this is no problem since the automatic logging preferably automatically indicates to the word processor for example which number and/or letter the user has been incrementing in each subsequent saving of the file), and/or for example the user can mark the relevant area in the file name and for example right click with the mouse in order to choose a menu option that defines this as the area that should be incremented) automatically. Another possible variation is that similarly for example the Internet browser can create an automatic increment of one or more numbers or letters in a url (so that the user can preferably move to the next page preferably with a single click instead of for example having to manually increase the number). Preferably the browser can for example automatically learn from the user after a few manual increments what area needs to be incremented and preferably for example automatically adds a “next page” (and/or also a “previous page”) icon in this case (or for example these icons are there before but start working for that page only after the relevant area in the url has been automatically learned or has been defined by the user), or for example the user can explicitly for example mark the relevant area and for example right click with the mouse in order to choose a menu option that defines this as the area that should be incremented (or decremented) automatically. Another problem is that for example Word does not allow an open file to be backed up for example by pkzip, and typically also keeps preventing this even if the file is saved for example with incremented numbers if is the first file which was opened. So preferably this is improved so that Word (or other word processor) does not block programs from accessing open Word files if they only open the file for reading, and preferably after the file is saved with a new name the original file with which Word was opened is released. Another possible variation is that preferably the word processor enables the user also an option for example to save a currently open file under a new name without closing the original window (or tab—if tabs are also supported in the word processor, as described elsewhere in this application) preferably like opening a link into a new page or tab in a browser (for example by adding this additional save option to the save file menu or for example by adding it as an option is the Save file dialogue box). (In the current prior art for example in Word the user would have to save the file under the new name in the same window and would have to copy the original file name before it and then user again Open file and past the name), Another problem is that for example in the prior art Word changing the language in the text (for example from English to Hebrew or vice versa) can affect also the text when the user saves or opens a file name, so preferably this is made independent in the word processor or for example in other applications, since the user might for example want to type in Hebrew but prefer for example the file name to remain in English all the time. In other words, as explained also elsewhere in this application, preferably the language of the file name for saving and/or for opening files is preferably remembered separately (i.e. preferably in a separate variable or variables) and is not affected when the user for example switches from working in Hebrew (or for example some other language) to working in English (or for example some other language) within the documents itself, and of course this means that similarly changing the language of the file name preferably has no effect on the language in which the user is typing within the document. Similarly, for example changing the language for example to Hebrew when filling forms in the Browser preferably does not change the language used in urls, since the user most likely wants to continue typing the url in English, so this parameter is preferably similarly remembered separately for the url and preferably the user has to switch the language explicitly in the url line if he/she wants to change the language there, and/or for example the language can be changed separately in on tab without affecting the language in other tabs. Similarly preferably changing the language in the dictionary does not change the language in the text of the document or vice versa. This is very important, since for example even in Word 2003, if the user is working for example on an English document and types for example a word in Hebrew in the dictionary in order to find the English word for it, then when continuing to type on the document itself the new text is typed in Hebrew until the user changes it back again, which is certainly not what the user intended. Another possible variation is that preferably the user can copy words from the dictionary into the main text also for example by a single click instead of having to use cut &amp; paste—for example by simply clicking on the word preferably the word is copied preferably to the current position of the cursor. Another problem for example in bilingual Word is that for example numbers or brackets can exist in either of the 2 languages, and for example many times Word breaks brackets or numbers that are attached to words in a way that the user did not intend—such as for example putting an opening bracket alone at the end of the line or breaking between the word and the number even if they are attached without a space between them. So this is preferably improved so that these things are automatically avoided regardless of the language in which the digits or brackets are. Another problem is that for example in Word 2000 if the user tries to translate a world in plural the system shows that it exists but does not show the translation until the user converts it to single, and in word 2003 in this case the single form is indicated and the translation is in single. So preferably this is improved so that if the word is in plural the translation can preferably show the translated word also in the plural (in addition to or instead of showing it in the single form, but preferably in addition). Similarly, preferably if the word is for example a verb in the present form (ending with “ing”) preferably the Word processor&#39;s translation or dictionary can show also the translated form also in the present form in addition to or instead of showing it in the normal form, but preferably in addition). Another possible variation is that the user can for example activate a command which automatically indicates all the words in which spelling errors were previously automatically corrected by the word processor, so that the user can check specifically these words to see if there were any such errors of changing the word to something that was not indented by the user. (This means of course that preferably the word processor (or other application) preferably keeps for each word in the same file or in a separate file a tag that says if it was automatically corrected and preferably also what it was before the correction). Another problem is that for example in Word if the user for example inserts by mistake a digit in the middle of a word (for example “t6hat” or “smart hom1e”) the error correction function ignores this and does not mark this as a possible error. So preferably this is corrected so that for example at least if there is a digit in the middle of a word (and/or for example also if it is attached at the beginning of the word and/or for example also if it is attached at the end of the word) it is preferably at least marked as a possible error. Actually it turns out even word 2000 allows the user for example to change the default so that words which contain digits will not be ignored, but there is no differentiation according to the position of the digit or digits within the word, so preferably this is improved so that the user can define separately if to report an error for example for cases where the digit or digits are at the beginning of the word before the letters, cases where the digits or digits are in the middle of the word, or cases where the digit or digits are at the end of the word after all the letters. Another possible variation is that preferably error checking and/or automatic correction is also for example enabled by default when the user is writing an email message for example in the email client or in the browser, preferably for example by including an error checking engine in the browser and/or the email client or for example the browser or email client can be configured to communicate for example with the error checker of the word processor. Similarly preferably search engines (for example Google) preferably automatically offer in such cases the correct word or words without the digit, for example “did you mean ‘smart home’?” Another preferable improvement for example in words processors, and especially for example in editors that are used for editing software programs (such as for example in integrated visual compiler environments), is that preferably the editor can mark automatically matching pairs of brackets in a way that the user can easily see the matching pairs—preferably by automatically showing each pair in a different color, and/or for example an unmatched bracket is immediately marked as an error. Another possible variation is to show them for example, instead or in addition, in a different style or for example in a somewhat different height, however changing the color is more preferable since it is more conspicuous and much more variations are available. Another possible improvement is that when the user wants for example to correct intermittently two (or more) sections in the same file (for example the claims and the relevant part of the specification in a patent application), preferably the user can for example press a key or combination of keys which causes the position in the word processor to jump automatically between the various last edited sections. This is preferably done by the Word processor preferably automatically saving a buffer of all the last separate positions that the cursor was last on (for example if the distance between them is more than N characters), and then pressing for example some key or key combination moves the position accordingly (This can be done for example automatically between the last two places, and if the user wants more jumps backwards preferably a different command is used). Another preferable variation is that preferably the automatic error checking of the word processor includes also at least some statistical and/or semantic checking of unreasonable words or word combinations that are probably a typing error even if there is such a word and/or eventhough it is grammatically possible, such as for example if the user writes by mistake “any pother way” instead of “any other way”. Since the word “pother” does exist and the combination is apparently grammatically possible, Word does not indicate any error, eventhough any normal human reader would immediately see that it is a mistake and the correct word is “other”. In order to accomplish this preferably the word processor uses at least some taxonomy of semantic knowledge, and/or at least the word processor preferably has a preferably large database of typical texts, for example from newspapers and/or books and/or web pages, and/or preferably all single words and/or up to a few word combinations are indexed according to how many times they appear (preferably based on previous preferably automatic statistical analyses of such texts), so that preferably the word processor can instantly check for example for highly irregular combinations (preferably especially if they are very similar to regularly used combinations, for example with only 1 or two letter difference) and/or at least run the check for example when a rare word is involved, etc., and preferably the word processor issues the error message especially if there is clearly a very similar word combination that is much more common (such as for example if the user typed by mistake “the if” instead of “then if”, or “than preferably” instead of “then preferably”, or “fir example” or “foe example” or “or example” instead of “for example” or for example “form the” instead of “from the” (which can preferably be marked as possible errors also for example because in the last two example it is two consecutive nouns), or for example “an also” instead of “and also” (which can preferably be marked as possible error also for example because it is ‘an’ followed by a non-noun), or for example “to choose” instead of “to chose” (which can preferably also be identified directly as a grammatical error of wrong verb usage), or for example “if course” instead of “of course”, or for example “and or” instead of and/or” or for example “Anther possible variation” instead of “Another possible variation” (which is clearly wrong also because a noun should not be before the word “possible”), or for example “Any by the way” instead of “And by the way” (for example at the beginning of the sentence), or for example “two many” instead of “too many”, or for example “two much” instead of “too much”, or for example “global worming” instead of “global warming”, or for example “form the” instead of “from the”, or for example “id that” instead of “is that”, or for example typed “more then” instead of “more than” or “better than” instead of “better than” for example without a “,” or “.” between the words—since that will almost always be an error, or for example types “be replaces” instead of “be replaced” or for example similarly with any other verb in this combination), or for example “It very hard” instead of “It is very hard” (again this can preferably be easily identified for example based on the fact that these are two consecutive nouns), or for example “from he” or “of he” and/or the word “he” followed by an additional noun, which means that the user probably skipped the ‘t’ by mistake for example when typing fast and it should clearly be ‘the’. Preferably the Word processor can also for example automatically update its statistics for example once in a while from one or more online web sites which for example automatically analyze texts (for example from newspapers and/or books and/or web pages, as explained above) and preferably enable downloading directly the relevant statistics of word frequencies, word combination frequencies, etc., as explained above. Another possible variation is that the word processor preferably uses also some additional preferably easy heuristics for catching grammatical errors, such as for example marking automatically as suspect cases where for example two verbs or two nouns appear one after the other, for example without a ‘,’ or ‘-’ or ‘/’ or other punctuation marks between them, which is usually a very good heuristic (which can also catch for example errors like “he book” instead of “the book”, etc.), or for example the word “an” followed by a verb, or for example the combination of words like “the” followed immediately by a verb instead of noun or followed by a conditional like ‘if’, etc. Although there are some exceptions they are relatively rare, so this can give very good results without having to really parse the grammatical structure (much more real positives than false positives)(preferably the word processor marks these suspect grammatical errors for example less conspicuously than word that don&#39;t exist in the dictionary). This is also very easy to apply since typically the word processor, such as for example Word, already has a built-in dictionary, so looking up to see for each word if it is for example a verb or a noun or other part of the sentence can be done almost instantly, for example by using a hashed look-up table. In cases of words that can be both a verb or a noun the word processor can for example avoid the marking as suspect error or for example take into account the likelihood of the combination according to the known statistics for example as explained above. Another possible variation is that for example the word processor can automatically correct for example all the cases of a comma appearing after a space, coupled to the next word, into appearing coupled to the previous word and followed by a space (and vice versa for example in Hebrew or other right to left languages), or at least mark these places as suspect errors. Another possible variation is that for example the word processor can mark as suspect errors for example cases where a verb ends with an ‘s’ after a noun in plural or without an ‘s’ after a noun in single (which is again very easy since the word processor can easily know if the noun is plural or single according to the built-in dictionary). Another possible variation is that if the word processor is not sure enough for making an automatic correction for an error the user can for example press a control key or choose a menu option which automatically lists more than one possible corrections for the same word for example as {word1/word2/word3} and then preferably the user can simply click on the correct option and it instantly replaces the word. Preferably the word processor also takes into account for example the layout of the typical keyboard (so that for example an error of adding a ‘p’ before the ‘o’ or for example substituting ‘o’ with a ‘p’ or vice versa is much more likely than for example making a substitution of far letters) and/or also takes into account acoustic information (for example words that sound alike, etc.). Another possible variation is that the word processor for example learns from recording the user&#39;s own behavior when such errors (for example typing and/or grammatical) are made and then corrected by user (especially for example if this occurs repeatedly), and then preferably warns the user automatically when such errors are made again and/or for example automatically corrects it the way the user has typically corrected it before. Another possible variation is that for example even while the dictionary is open for example in the word processor, for example clicking on any word in the word processor preferably automatically acts also like inserting the word into the dictionary and activating the translation Of course various combinations of the above and other variations can also be used.   15. Another problem is that when opening files for example with the windows dialogue box (for example from Word) the dialogue box does not display the full file name if the file name is too long. In windows 98 the problem was even worse since the dialogue box cannot even be enlarged at all, whereas in Windows XP at least the user can enlarge the window of the dialogue box by dragging for example its bottom right corner with the mouse. However, this is still not convenient, since the system allows for example to define file names of length up to 256 characters, but the dialogue box by default will typically display only up to a little more than 80 characters. So preferably this is improved so that the dialogue box preferably automatically adjusts its size to a size that is sufficiently large to display the full file name if one or more of the file names that are displayed is longer than the default, and/or for example a slide bar is added (for example at the bottom) that allows the user to scroll and see the full name (in other words preferably the dialogue box automatically finds the largest name and adjusts its size according to it). However, sometimes the name is even too long to fit the line even when the box is in full size and/or for example too long to fit the top line of the Word Window (and/or in other applications), and/or for example it shows truncated in the yellow explanation box that Word shows when holding the mouse over the file name, so preferably is such cases the filename is preferably automatically for example wrapped into two or more lines and/or for example the font that displays the file name is automatically reduced in size for example by making it smaller and/or thinner, but more preferably by making it only thinner, and/or for example the user can click or otherwise jump to the end of the line and see the rest of the file name and/or for example cause the filename to scroll for example sideways for example my moving a bar and/or for example the full file name or the end of it is shown automatically for example by any of the above means for example if the user hovers over it with the mouse. In the prior art the slide bar is enabled only if more file names are displayed sideways, but moving the slide bar jumps one column to the side without letting the user see the rest of the name if the name is too long. The automatic resizing can be done for example also in other types of Windows, so that for example when sending email with attachments for example in Netscape preferably the size of the right internal window that shows the attached file names preferably automatically increases if the file name is longer, at least for example if there is sufficient room, since typically the email addresses on the left internal window are not very long. Another problem is that if for example one file name is very long the dialogue box shows a large gap between the columns of file names even if for example between two columns which don&#39;t contain such a long file name. So preferably this is improved so that the distance between each two columns is for example preferably just a little more than the length of the largest file name in the left column. Another possible variation is that for example even in the dialogue box file names that are too long can for example be automatically wrapped into more than one line instead of further increasing the distance between the columns beyond a certain threshold and/or for example the fonts of the long name can for example be automatically reduced in size or at least only made thinner, preferably without affecting the rest of the display (preferably for example the dialogue box decides about this automatically on a need basis). Another possible variation is that for example the dialogue box can automatically display also the date of last modification for each file name (for example near each file name automatically, or for example at least if the user hovers the mouse over the file name), and/or the user can for example request to sort the dialogue box display by the last modification date instead of alphabetically. Another possible variation is that for example before sending the email with attachments the user can for example easily change the order within the list of attachments, for example by pointing the mouse to one of the attachments and dragging it to a different position in the list. Another preferable improvement is that for example when deleting a file in the dialogue box that displays existing file names, preferably by default immediately after the deletion the display is updated so that the list of files is displayed more or less in the same position (preferably the display up to the deleted file remains the same, and is updated only from the deleted position onwards), since typically the user will want to continue at the same place after the deletion. In the prior art deleting a file in the dialogue box causes the display to jump back automatically to the beginning of the list. Another problem is that the dialogue box that allows the user to choose directories and files and the explorer Window show file extensions only when the file type is unknown, so for example if the same file name exists both as an rtf file and as a Word doc file the user has no indication which is which (unless he/she tells for example Word to show only files of one of the types). So preferably this is improved so that in the dialogue box and/or in the explorer Window or for example in the automatic list of recent files which can be reopened the extension is shown even when the associated application is known and/or for example if the user opens it for example with Word (or with some other application), then preferably the extension is displayed for example on the top bar of the window, so that the user knows which file he/she opened and so that if for example he/she opens for example both a doc and an rtf version of the same file he/she knows which is which. Another problem is that when the user searches for a specific file or file pattern (for example a file name with a wild card) the explorer window or dialog box shows first directory names and only afterwards files, which can be very inconvenient if there is a large number of sub-directories in the directory where the relevant files are. So preferably in the windows explorer and/or dialog box and/or in similar utilities the files are displayed by default before the directory names and/or for example the user can preferably easily indicate which of these orders he/she prefers. Another possible variation is that for example instead of or in addition to the icon that shows the associated application (for example Word) the window can show also an Icon that represents the general type of the file (for example music file, video file, word processing file, C program file, HTML file, etc.) regardless of the associated application. Another possible variation is that for example even when an internal Window of a program is in front of a background window of that program and does not allow accessing the background window for example until the front window is closed, preferably the OS automatically allows the user at least to move the previous window and/or perform at least other acts that preferably do not change the way the software behaves but allows the user at least to control the view of the background window.   16. Another problem for example in Word is that drawing tools are very limited so that for example various lines can only be positioned at certain minimal jumps of a few mm distance from each other instead of at any desired pixel positions. This creates unnecessary limitations on the available resolution and other problems. So preferably this limitation is removed, so that the user can preferably position any object on any position where a valid pixel exists (an object can also be for example a line within a more complex object—for example a rectangle, so this can mean of course not only moving the objects but also for example moving parts of them, i.e. preferably the user can also change their size in pixel-level resolution). Similarly there is a problem that the user cannot for example simply mark one or more images for example with the mouse, for example in order to delete it or cut and paste it elsewhere. In the prior art Word the marking usually works only on a group of images depending for example if there is a text before and after them that can be included in the marked block, and so that normally the user has to mark manually multiple elements in an image in order to copy or move it or has to manually group the image. So preferably this is improved so that the user can simply mark any area in an image or part of it (for example even according to pixel lines and/or columns, or for example by marking a rectangle or other shapes around whatever part he/she wishes like in paint programs) and then for example delete it or copy it or move it. This is very easy to do since the word processor (or other application) knows which part of the image or images is displayed within the marked area. Another possible variation is that for example after the user marks such a section he/she can for example not only cut &amp; paste and/or copy or delete the marked section but also for example rotate it so that preferably all the elements in the marked section are rotated in synchrony, etc. (for example in any desired amount of degrees, etc.) and/or for example move it without having to tediously mark all the elements one after the other, and/or preferably the user can also for example reduce or enlarge the image for example by pulling its corner (for example like any image from a file) while preferably keeping the proportions (this should be no problem at all since for example images composed of lines or dots or squares or other automatic shapes are vectorial anyway and so are true type fonts, so the word processor can for example automatically increase or reduced the font size in the same proportion that the other vectorial elements are increased or reduced). The application can do this for example by vector graphics manipulations or by computing the changes on a pixel basis. Another possible variation is that the user can for example mark one or more sections in the word processor, such as for example text, and then rotate it, for example by any degree or at least for example by jumps of 90 degrees, so that for example the user can create vertical text (such as for example tabs with vertical tabs with phone numbers which people can later cut-off at the bottom of an advertisement) and then preferably the user can also edit this text while in the rotated position (this is preferably kept as text and not as an image, so that the user can preferably work with it like any other text in the word processor), and when editing it preferably the user can work for example with this text as is or for example can temporarily rotate the entire document so that the rotated section appears upright, or for example this is done automatically by the word processor while the use is editing the rotated text. Another possible variation is that for example if the user is marking multiple elements in the image and the for example clicks on the next element without keeping the finger on the shift key (thus losing all the previous marks), preferably by pressing for example ̂Z or some other control the user can undo the last click, thus restoring all the previous marks. (Preferably this undo feature for restoring the marking can be used for example also in other similar situations, such as for example when marking multiple files in the explorer and/or for example when marking multiple items in a list in some browser form, etc). Another possible variation is that preferably the user can include for example also in Word documents and/or for example pdf documents also instead of still images video files (such as for example “.avi” files, “.flv” files, “.wmv” files, etc.), so that preferably the positioning of the “image” is done similarly to the way a normal still image is positioned, but preferably when the user is on the page with the video image then preferably the video starts playing automatically (for example until the user clicks on it to stop) or for example the image is marked as video so that the user can click on it to activate it, and preferably the user can for example click on the image or for example drag its corner in order to increase the size of the displayed video or for example increase the page that contains the video and this increased also the playing video (for example like Opera and MSIE 7 work now with embedded videos in web pages). Another possible variation is that preferably when using for example the wavy line (in the automatic shapes menu) preferably the user can use undo (for example ̂z) to cancel the last curve or go back to previous curves. This is better than the prior art for example in Word, in which if the user makes a mistake he/she has to delete the wavy line start creating it again. Another problem is that for example if the user types the word “OSs” in Word, the word processor keeps trying to correct it each time automatically to the word Ross when the user types the space in order to enter the next word, so if the user doesn&#39;t notice it, the word is completely diverted from the original meaning, and Word keeps doing it again and again no matter how many times the user corrects it back (even the public Word 2007 beta 2 still does this). So preferably this is improved so that the word processor preferably automatically learns from the user&#39;s behavior and does not keep correcting the same word if the user goes back and corrects it one or more time back to the version which the word processor “thought” was wrong. Another possible variation is that preferably the word processor can mark with a special marks all the cases where words were automatically corrected so that the user can review them and/or for example marks them when the user activates a relevant command, and/or for example if the user later corrects for example such a word back to the previous version but there were earlier cases which were automatically corrected and the user did not correct back (perhaps because he/she didn&#39;t notice) then preferably the word processor can for example automatically mark these specific other instances of the word or and/or for example ask the user if he/she wants to correct them, automatically (preferably with verify).   17. Another possible variation is that preferably for example in word processing programs and/or for example Internet browsers and/or other software preferably the user can move any icon and/or for example any menu item and/or sub-menu item (preferably including for example within pull-down menus) to any desired position (preferably simply by dragging it with the mouse) and preferably the same icon and/or menu item automatically continues functioning on the new position (this means of course that preferably the user can also for example change the position of the tab handles line to be lower or higher or even for example move it to the bottom of the browser windows instead of the top part), and this new position is preferably saved automatically also after the user closes the application, and preferably the user can also undo any such changes, preferably even after the application has been closed and reopened (which is preferably accomplished by keeping a rollback log in a separate configuration file and preferably for example by using variable pointers for the menu items). This is better than the prior art in which for example the user can sometimes move certain groups of elements together but not in a consistent manner and not for each item independently (for example in Microsoft Word). This feature is preferably supported automatically for example by compilers such as for example visual C, so that preferably the programmer does not have to do almost anything in order to enable it. Another possible variation is that the user can also for example change the position of the normal boxes on the taskbar that represent normally running programs (preferably by dragging them with the mouse), so that the user can conveniently re-arrange their position without having to close and reopen these programs.   18. Another possible variation is that preferably the user can for example mark an area in the word processor with the mouse and preferably activate a command which for example automatically removes any table or other structured formatting from that area, so that preferably the text is still divided preferably the same way, but after this the user can for example make any other changes as if the table or other structure never existed. Another possible variation is the opposite—so that the user can for example enter text that looks like in a table but without the actual structure and then activate a command which automatically adds the structure—for example by guessing the most likely structure that fits the given shape of the text.   19. Another possible variation is that for example the copy command (typically ̂C) can also be activated cumulatively (for example by activating some flag), so that for example a certain sequence of ̂C commands can create a cumulative buffer of for example consecutively pasted texts, so that afterwards for example ̂V at a certain position will preferably paste back the consecutive group of pasted texts as one sequence.   20. Another possible variation is that preferably the word processor automatically checks the date in the system in short intervals (for example every few minutes) and thus updates the date field automatically whenever it has changed (for example when the user has included the date field in each page header), and not just if the user reopens file or prints it, as is done for example in the prior art Word. Another possible variation is that for example the user can change page definitions (for example size of top and bottom margins and/or other parameters) also for example for a single page or range of pages or for example a list of pages and not just automatically for all the pages as in the prior art Word.       
 
         [0044]    Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0045]    Additional improvements in the OS preferably include also at least one of the following:
       1. Preferably the OS allows the user to define at least one User which the system (such as for example Windows NT or XP) will enter by default and without a password if the user does not request to enter a particular User after a certain time (for example 30 seconds 50 seconds or other reasonable time limit, which can preferably changed by the user) after the system reaches the menu that&#39;s asks to choose a User. This has the advantage that for example after a temporary power failure the system can automatically resume the original User. Preferably this is accompanied by the ability to define for example a sequence of actions to be taken upon entering this User by default, such as for example connecting to the Internet and activating a server and/or whatever other program or programs need to be resumed after a power failure. This is somewhat similar to programs in the startup menu, except that this feature is preferably more powerful, so that it enables for example to define also various sequences of actions or for example to carry on automatically certain activities only if the User was entered automatically by default. Another possible variation is that preferably the user can, preferably easily, also define the priorities for programs in the startup list (for example by dragging them to the top of the list or marking their priority), so that for example the user can specify that for example the firewall will always start before any of the other programs or at least for example among the first 3-4, and/or for example the OS itself and/or for example the security system for example automatically moves the security system and/or the firewall to the top of the list and/or makes sure that it runs below any other applications and/or drivers and/or for example in a ring below the other drivers and/or below the OS and preferably also makes sure that it stays there, and/or for example at least part of the security system starts running even before the OS or below it, as explained in other applications by the present inventor. In addition preferably the system also allows the user for example to add programs to the startup list for example by simply dragging them onto the list. Another possible variation is that if the system enters the default User without password, preferably it enters a limited mode where for example it takes no commands from the keyboard or mouse and/or has other limitations, for example until the user for example comes back and enters some password. For example the system can enter immediately the state that it would be in if a screen saver was activated and a password is needed to resume operation with the keyboard or mouse. Another possible variation is that the user can for example request that the user selection screen will not be shown at all for example when returning from sleep mode and/or for example from any mode (including for example normal boot), so that for example every time the system comes back for example after sleep mode it will go directly into the desktop (for example of the last user that was working, if more than one user is defined), and/or for example into the user which is defined as default. Another possible variation is that preferably when resuming for example from restart and/or from logoff and/or from sleep mode or hibernate preferably by default the OS automatically reenters the last user in which it was (preferably after waiting N seconds as described above), for example at least if no other default user was explicitly defined and/or if the return for example from restart and/or from logoff and/or from sleep mode or hibernate is done within a certain time limit from the time of starting the shut-down (for example within N minutes). Another possible variation is that preferably while waiting for the user during booting to click on a user, preferably the OS automatically starts loading into memory already for example all the drivers and/or startup programs which have to load anyway for all users, so that when the user clicks on a specific user the boot will continue faster. Another possible variation is that at that stage (or for example after the OS finishes loading the common things for all users, if the user still hasn&#39;t clicked on a user) preferably the OS loads already also other things that are different for specific users (preferably starting with the last used user or the most often used user), and if the user eventually click on another user then for example the OS preferably automatically removes from memory for example the startup-programs and/or drivers that are not relevant for that user. Of course various combinations of the above and other variations can also be used.   2. Preferably if the user uses for example write-once CD&#39;s (and/or for example DVDs) for backup and uses direct writing software, such as for example DirectCD, if the user copies the same file more than once onto the same CD (to the same directory), then preferably the backup software can automatically rename the old files for example with some automatically sequenced extension, so that the user can automatically keep and track also older versions this way. This is quite useful for version tracking and is better than simply overwriting the file, since in such CDs the old data cannot really be overwritten anyway. Of course, preferably the user has an option of turning this feature on or off, and/or for example can activate it retroactively for example for write-one CD&#39;s or DVD&#39;s in which it has not been used (in this case preferably the system automatically reconstructs the version sequencing according to the time and date each “deleted” previous version was saved). Another possible variation is to apply such automatic sequencing automatically for example also to other drives and/or directories that the user defines as back-up drives or directories and/or to other types of backup devices. Another possible variation is to enable by default (or for example to allow the user to request it) automatic backup of important files to the default backup directory and/or drive and/or device, so that for example each doc file (or for example program source file, or other for example office type of file) that has been created or changed and has not been updated for more than a certain time period (for example 1 day or a few hours or a few minutes), and/or more preferably for example after a certain threshold amount of change even if less time has elapsed (such as for example after every few words), is automatically backed-up on the default back-up media and/or for example on the hard disk (for example in a special backup directory or in the same directory but preferably with some extension to the name so that even if the user for example erases something important by mistake and then saves the file, preferably the backup with the missing part also exits), and/or for example the word processor or other application saves only a roll back log of the changes in order to save space, and/or for example browser bookmark files are back-up like this, etc. (The important types of files are preferably defined automatically by default and/or user-defined). This can be a great help for example for users who forget to make backups. After the media becomes full and/or for example shortly before that the system can for example report this to the user and prompt him/her for example to insert a new blank writeable CD (or other media), etc. (In case of backup on the hard disk preferably the older backups can be deleted automatically for example after a certain amount of time has elapsed and/or after there are for example too much space taken up). (In case of the bookmarks file for example, if for some reason the latest version has crashed or was damaged in anyway, preferably the system can automatically reconstruct the latest version for example by taking the last backed-up version and adding to it preferably automatically all the links that were visited from that time onwards, for example according to the browser&#39;s recent history list). Another possible variation is that for example normal CD creation programs which write a CD file image as a single transaction, such as for example CD Creator, preferably enable compressing files on the fly (for example as zip or other common compression formats). This is better than the to the prior art, where such compression is available only when the CD is accessed like a disk, for example through programs like “Direct CD”, which when there is a large number of files write to the CD significantly slower than for example programs like CD creator. Another possible variation is that the user can for example select files for backup according to a certain range of sizes (for example backup automatically all the files that are smaller than 1 megabytes or 10 megabytes, etc.) or for example define automatic backup rules for files according to their types (so that for example every new doc file is backed up automatically for example more frequently than less important files, etc.). Another preferable improvement is that like smaller pocket-sized CD&#39;s, preferably DVDs and/or similar larger capacity drives (such as for example blue-ray or High Definition DVDs) support also smaller pocket-size DVD&#39;s, preferably both as burn-able media and as ready pre-recorded media. Another possible variation is that instead of or in addition to selling high definition DVD movies as Mpeg2 files on Blue ray or HD DVD media, preferably the content suppliers make available high definition movies on normal DVD&#39;s (at least for example for the next few years until the blue ray and HD DVD drives and/or devices become cheaper and more prevalent)—preferably by using mpeg 4 (for example divx or xvid) or similar or other high-compression format, while preferably keeping the normal DVD menu system and anything else with the normal look and feel of DVDs (in other words this preferably includes also for example multiple audio tracks and multiple subtitles which can preferably be switched on the fly like when normally playing the dvd in MPEG2). Similarly, preferably programs that convert from Mpeg2 to Mpeg4 or avi or divx or similar high compression formats preferably automatically keep also dvd menus at least as an option and/or at least keep automatically also the information that divides the stream into chapters, so that on playback the user can preferably instantly jump between chapters. Another possible variation is that preferably heavy processing programs such as for example applications that compress video files into Avi or Mpeg 4 or other high-compression formats preferably automatically divide the file into multiple sections and preferably run the processing of each section in a separate independent thread, so that the OS can automatically optimize them for example when multi-threading and/or multi-core processors are used (which is no problem since base frames are used anyway at certain intervals, so preferably each thread starts of course with an independent base frame). Another possible variation is that the OS tells such applications for example how many threads and/or cores exist and/or for example automatically recommends to such applications how many threads to create while taking into account for example what other processes are currently running, so that preferably if for example it is a single-core processor preferably fewer threads are created so as to avoid unnecessary overhead (preferably these recommendations are kept for example in some standard dll or file or for example are communicated as parameters when the application runs). Another possible variation is that when the user activates such a program the OS itself can for example automatically divide the file into multiple sections are run the program in a separate thread on each section, but that is much less preferable since it is much more efficient and less problematic if the application itself is designed to work as explained above. In addition, if the user is normally working at a resolution below the maximum resolution available on the giver monitor and graphic card, preferably when playing high-definition movies or videos (from whatever source or method of compression), preferably, at least when the user is watching the movie at full-screen mode, preferably the player can automatically switch the display to a higher resolution (which is preferably the highest resolution supported by that monitor and graphics card, but preferably the user can define or pre-define what resolution to jump to in this mode, since the user might for example prefer to go in this mode to a resolution below the highest one available in order to have for example a higher refresh rate), and preferably when increasing the resolution the player preferably automatically scales for example its skins and menus (including preferably fonts, icons and anything else in the user interface, and preferably also for example the font size of the subtitles) to appear preferably the same size as in the lower resolution which the user normally works with, so that preferably everything seems the same size at the higher resolution except that the picture is sharper, with more details. (However, preferably the user can also change for example the size of the above mentioned elements and/or user interface and/or for example of the subtitles, preferably independently of the resolution, if for example he/she prefers them bigger or smaller in general). Another preferable variation is to improve DVD capacity even much more for example by using UV or extreme-UV lasers instead of red or blue. However, preferably the media for such DVDs are made sensitive to writing only at a strength and/or frequency which is sufficiently different from normal UV radiation from the Sun, so that for example exposure to the Sun will preferably not have a degrading effect on the media or at least only a small effect. Another possible variation is that for example when making backups onto multiple CD&#39;s or DVD&#39;S, for example with programs like Nero (multi-volume backups), preferably the backup system automatically tries to optimize the division of files between volumes in a way that takes into account file sizes, so that preferably there is no need to break large files between volumes (unless of course the file itself is too big to fit on one volume). Another problem for example with programs like Nero is that the user can only request a backup with file compression or without but cannot request that only some files be compressed and some not. So preferably this is improved so that for example the user can mark near each selected file or directory if to back it up compressed or not, and/or for example the backup system can automatically decide for example according to file type or extension or other characteristics if to compress a file or not (thus for example automatically avoiding compressing of files that cannot be compressed efficiently or are already compressed, such as for example mp3 files, mpeg files, avi files, zip files, etc.) and/or for example automatically compressing text files (for example doc files or program source files), unless for example the user explicitly requests not to compress them anyway. Another problem is that for example when burning to a cd or DVD with automatic verify, the burning can take much longer than burning without verify (sometimes even for example 3-4 times longer)—typically because the files are fragmented and/or scattered in various places on the disk and so either the disk heads or the DVD or cd laser head has to jump all the time when comparing sections since the sections do not appear on the same order on the hard disk and on the cd or DVD. So preferably this is improved so that especially if it is for example a backup (which is by definition not accessed too often but the verification is important), preferably if the user requests burning with verify, preferably the sections are automatically arranged on the cd or the DVD at the same order that they are on the hard disk (or for example other storage media), so that the cd or DVD becomes organized in a less efficient manner but the verify can be much faster since both heads preferably move in the same order (preferably this is accompanied by planning in advance the movements of the head of the hard disk to move in a single direction, so that preferably the head can read parts of the relevant files not file by file but by the order of the relevant sections regardless of the division into files). Another possible variation is that preferably the burning software offers the user also for example an intermediary verification option—which is preferably based on a preferably large CRC or similar fingerprint which is preferably taken for example for the entire set of files in the backup or for example for each file or for example even for sub-sections of large file for files that are for example bigger then a certain threshold or for example even each physical sector on the CD or DVD, and preferably these values are kept in the RAM memory and so preferably the verification is simply based in reading the files or sectors back from the backup media and comparing them with the CRC or other fingerprints that are kept in memory from the original files. This can be very reliable since the chance for error is very small, and thus the user can have almost certain verification in a way that hardly slows down the burning or for example slows it down only by the time it takes to read again all the data from the cd or DVD. Another possible variation is that for example while burning each section (which can be for example a sector or any other unit which preferably fits in a convenient hardware supported access window preferably regardless of division between files—for example the area covered by one step of the laser head), preferably the laser head gets the crc or fingerprint value from the original data for that sector and preferably automatically reads back the data from that section after writing it and compares it to the fingerprint before going on to writing the next position, thus making the verification preferably almost take no more time than without verification since the laser head does not have to go over the entire data again for reading for verification but moves to each location only one—for writing and then reading back and comparing to the original fingerprint of the section. For this the burning software (and/or for example the firmware of the CD or DVD) preferably first computes the relevant crc or fingerprint value of the section that it is about to burn, and then burns it and reads it back and compares it preferably before moving the head to the next position. In order to enable this preferably the switching speed of the laser is improved so that it can preferably switch instantly between writing mode and reading mode, or for example more than one laser exists on the same head, so that for example one laser is used all the time for writing and another laser is used all the time for reading. Another possible variation is to put a copy of this fingerprint or CRC also on the CD or DVD itself, for example at the end of it or for example near each file or each section which is covered by said CRC or fingerprint (this can be used for example for later comparison, for example if the user wants later to check faster if the data is still intact, for example after a few days or weeks r months or other period). Of course in this and in all other features that refer to hard disks or to cds or DVDs the same or similar principles can be used also for example with other storage media and/or other backup media that are available or will become available in the future. Another possible variation is that for example when the user copies a large number of small files between two hard disks (for example by using xcopy or for example by copying whole directories through the explorer)(for example when hundreds or thousand of files or more are involved), preferably the OS can automatically optimize the speed of the copying by first reading the FAT of the source disk into memory and then preferably copying the files in the order they appear on the original disk, in order to reduce the number and length of disk-head jumps needed. Another possible variation is to do this also at the level of sub-sections within such file, so that even if they are fragmented this will still work efficiently, except that in this case the price is that the files may be similarly fragmented in the target disk. Another possible variation is that preferably when there are for example 2 or more processes or threads which work intensively with the hard disk (such as for example when copying or processing large files or for example if a spyware removal program and antivirus program are running independently at the same time), and preferably especially if they work automatically without user interaction at this stage, then preferably the OS automatically changes the frequency of swapping between them to a lower rate compared to programs which the user interacts with, so that preferably there is much less overhead of disk jumps when switching between these tasks. (However preferably the antivirus and spyware scans are preferably done by a single program which preferably combines the signatures and/or heuristics of spyware and antivirus detection into the same process so that preferably files are scanned only once for both when needed). Another possible variation is that in order to avoid slowing down the computer preferably for example antivirus scans and/or spyware scans can be configured so that they are performed (for example by default or at least as one the options) for example automatically only when there is no other disk activity for some time or for example when the user is away, for example in a way similar to the way the Google desktop indexing works. Another possible variation is that preferably when copying files for example to CD or DVD, preferably at least as one of the options, but preferably by default, the burning program preferably keeps automatically a log of preferably all the copied files, preferably with the date and the division between cds or dvds, and/or also for example with the CRC and/or other fingerprint or fingerprints preferably for each such file (preferably including its full path information), so that the user can easily find them later and/or can for example request a verify to run for example at a later date for example in order to check the correctness of the copy on the dvd or cd for example if the user didn&#39;t use verify during the burning or if the user wants to check for example if the files remain OK after a certain time period has passed. Another possible variation is that for example the fc.exe (file compare) command for example in cmd mode or similar command is improved so that it not only works with wild cards, thus comparing automatically the files that match by name (or for example preferably automatically noting when the size and/or date is different, which means that for example no actual comparison is needed), but can preferably also receive for example preferably multiple partition letters and/or paths as parameters so that it can search for appropriate file names in more than one directory or partition, or can for example look for the relevant file names automatically anywhere on the disks, in which case preferably it can for example get preferably instantly all the relevant file names for example from the automatically indexed desktop search service. Another possible variation is that preferably DVD and/or CD drives and/or other devices that have a moving mechanical part when they are opened preferably have sensors that automatically detect for example if there is a mechanical obstacle, such as for example if a chair or other object does not allow the tray to fully come out, or for example if the CD or DVD has not been placed properly at the center of the tray and gets stuck when the tray starts to go in, and preferably when the sensor or sensors detect such a problem preferably for example the engine that moves the tray preferably immediately stops and/or moves a little back in the other direction and/or for example the engine releases the tray in such cases and allows the user manually to push it in or pull it out without resistance, for thus for example making the drive behave temporarily like a cd or DVD drive in a laptop in which the tray is pushed in or out manually by the user. This is important since otherwise mechanical damage can be caused to the tray or to the media. Another possible variation is that preferably the CD and/or DVD drive has also at least one additional eject button, preferably for example at the left and/or top side of the front of the drive (or instead of the normal eject button on the right, but more preferably in addition to it), because many times the PC is in a tower case on the floor to the right of the user, and so in the prior art the user many times finds it less convenient to reach the eject button on the right and also usually has trouble seeing it when the drive is open, which causes many users to close the cd or DVD tray by pushing it (instead of pressing again the eject button), which is more dangerous. Another possible variation is that for example in interfaces that allow switching between internal hard disks without opening the computer box (for example by sliding a disk and out of a box that sits in an empty 5¼ inch slot), preferably the box contains a mechanical element which is automatically moved when the computer power is on—to a position that locks the disk in, and is moved back automatically when power is turned off into a position that allows removing and inserting a disk—in order to make sure that the user does not swap a disk while the computer is working. Another possible variation is that for example the mainboard is improved so that the user can indeed swap disks even without turning off the computer—for example by an automatic switch that can automatically temporarily turn off the power supply to the hard disk in a safe way. Another possible variation is that preferably for example the computer&#39;s power supply is improved so that it stores sufficient energy to keep supporting the computer for about 1 or a few minutes (for example like a UPS, except that this is preferably integrated in the power supply itself and preferably just for 1 or a few minutes) and preferably when power outage is detected preferably the OS preferably receives a signal from the power supply or otherwise senses this and preferably immediately saves an OS state image and automatically enters hibernation, so that preferably within a minute or similar duration the power can safely run out. Another possible variation is that for example if the electrical company needs to shut down the electricity for a certain time which is known in advance for example in a certain area, preferably it can transmit some data signal for example over the power lines themselves for example a few minutes in advance, preferably with information about the start time and the estimated duration of the power outage, which is preferably read by the computer and enables the OS t enter hibernation. Another possible variation is that the user can switch between 2 or more disks for example by pressing or moving or rotating a preferably external preferably one or more electric switches on the outer side of the computer case, which preferably switches between them preferably through a hardware multiplexer, so that it preferably cannot be overridden by software, except that the user does not have to physically slide disks in or out. This is preferably done for example by creating computer cases which have the multiplexer built-in and preferably the hard disks sit in their normal places and the switch that operates the multiplexer preferably is connected electrically to the multiplexer and preferably protrudes for example at the front panel of the computer case, or for example in existing computer cases preferably the multiplexer and the switch can preferably be added for example by locating the multiplexer at the position of one of the possible externally accessible drives (so that for example the multiplexer can preferably occupy for example the space of a 5¼ drive or the space of a 3½ drive, but preferably it can use either of them for example by being the size of 3½ and coming with a removable frame that makes is also fit 5¼), and in this case the electrical switch is preferably at the front panel of the drive which the multiplexer occupies. In both cases preferably the set of 2 or more disks that the user want to switch are preferably all connected for example to SATA or IDE connectors on the multiplexer, and the multiplexer is preferably connected for example to a normal SATA or IDE connector on the mainboard or for example to both of them, so that preferably the user can even witch for example between disks of either type, in which case preferably the multiplexer connects SATA disks to the SATA connector and IDE disks to the IDE connector. Another possible variation us that the user can either switch only between disks of the same kind (for example all disks in the switch-able set have to be SATA or all of them have to be IDE). Another possible variation is that the multiplexer connects only for example to a single SATA connector or only a single IDE connector on the mainboard an preferably has circuitry and/or DSP and/or processor which can convert SATA interface to IDE or vice versa so that the set of switchable disks can still contain multiple types of disks. Another possible variation is that the multiplexer is for example integrated on the mainboard, so that the disks that the user want to switch between are preferably connected to various for example SATA or IDA connectors on that multiplexer section of the mainboard. Of course similar configurations can be used also to switch for example between additional or different types of disks which might exist today or in the future. The multiplexer preferably works only on the data connector so that the each of the disks is preferably connected to the power even when switched off, or for example the multiplexor switches also the power between the disks—preferably in systems in which the switching is done when the computer is off. Another possible variation is that the disks are connected normally and all the switching can be done for example through the BIOS but there is preferably at least part of the BIOS which cannot be accessed through the OS or through software (so that preferably even in order to flash it preferably the user for example has to press a special switch that enables it, so that the OS or various software cannot override this switching), or for example through a program that preferably runs below the OS (such as for example the hypervisor for example in systems that are supported for example by Intel&#39;s by Vanderpool or for example the similar AMD technology), so that preferably the disks that are switched out become invisible to any OS&#39;s or other software running in that computer, and preferably for example through this multiplexer and/or through the bios and/or the OS or the hypervisor, preferably one or more hard disks can also for example receive a command to stop rotating until further notice (preferably through command to the S.M.A.R.T. interface, so that the user can temporarily define drives who will preferably behave as if they were physically disconnected. Of course the hypervisor can preferably also segregate between virtual environments for example at the level of partitions and/or directories and/or even files or sub-files, (preferably based on saving only the changes separately), so that preferably one or more of these can me for example made accessible to only one of or some of the guest OSs, however segregating at the level of physical hard disks can involve even stronger hardware enforcement, for example by the hypervisor electronically activating such a hard-disks multiplexer when switching between OSs (at least in this case preferably the multiplexer works only on the data connector, so that preferably the all the switched disks are of course preferably fully powered and rotating all the time). Of course this can preferably be done also for example in a configuration in which one or more of the disks can be shared between the OSs. Another possible variation is that preferably through the hypervisor the user can define for example which physical disks are visible to which OS or OS&#39;s, so that preferably any OS or software installed on the computer can only access the hard disks through the hypervisor (preferably by enforcing this through the processor itself). This is much better than the prior art, in which the user can enable or disable disks through the BIOS but for example an OS like Windows Vista ignores these BIOS definitions and sees all the disks anyway. In addition, preferably if the multiplexer is used then preferably it connects to one or more connectors on the mainboard that enable booting, and if for example the solution with the hypervisor or the hidden BIOS part is used then preferably all the connectors can be made bootable, since otherwise the switching ability might be limited. Another possible variation is that for example when using KVM or similar switches for sharing for example a monitor, mouse and keyboard between two or more computers, preferably the monitors are improved so that they can for example also display at the same time data from more than one computer, so that for example if an urgent message from one of the computers needs to reach the user then for example at least a small part of the screen can be used for example to show the message from the other computer or at least to let the user know that he/she should switch to the image from another computer for an urgent message, which can be done for example by the monitor being able for example to combine images for example from two or more input connectors, and/or for example at least some code can be sent by a computer to the KVM in order to request temporary control of the screen for a really urgent message, and/or for example the KVM switch itself can interfere with the video signal and for example temporarily overwrite a small area in it with a message from another computer. Another problem is that even when for example two or more computers connected through the KVM share the same resolution and refresh rate, when switching between them the screen still goes blank for a few seconds, which can be very annoying and inconvenient. So preferably this is improved so that the switch is preferably more or less instantaneous—for example like when switching between windows or for example like switching between OS&#39;s for example with the Vanderpool or similar technologies. For this preferably for example the KVM switch preferably assumes that the resolution and refresh rate have not changed on computers which are currently not routed to the screen (since obviously the user normally cannot change them without first switching to that computer, unless for example the user connects or disconnects a computer on the fly, in which case preferably the KVM checks again the resolution and refresh rate on the newly connected computer preferably at the time of connecting it), and so preferably when switching to any of the connected computers preferably the KVM switch assumes that it is the same refresh rate and resolution as in the last check, and so can preferably make the switch instantly without the screen going blank for a noticeable period, and/or for example if the OS has a problem with that, preferably the user can tell the OS to skip resolution and refresh rate checks when switching back to the computer and/or for example the KVM switch itself can preferably constantly or regularly send information back preferably to each of the connected computers so that preferably the OS thinks that it is connected to the monitor even when switched off, so that the OS does not feel any change when being reconnected to the monitor and does not make any checks then, or for example the OS is improved so that it can be made aware of the KVM for example through some standard protocol (which is also preferable for example in order to enable sending urgent messages when needed even by a computer which is not currently routed to the monitor, since the OS should preferably know for this when it is connected or not connected to the monitor), and so preferably through this protocol the KVM can preferably let the OS know for example if the resolution and refresh rate are the same on the other computers, so that for example no checks or changes are needed when switching. Similarly, for example when switching between OS&#39;s for example in systems with Vanderpool or similar technologies, preferably for example the Hypervisor and/or the display card can perform similar functions so that there is no blanking out of the screen when switching between OS&#39;s, at least when the refresh rate and resolution are the same. Another possible variation is that for example even if the resolution is larger for example on one of the OS&#39;s, preferably the hypervisor and/or the display card can (preferably by default and/or as an option which the user can choose) for example still enable preferably instant switching between the OS&#39;s—for example by keeping the higher resolution even when switching to the OS with the lower resolution and automatically scaling everything for example by a DSP in the display card so that it appears the same size even with the higher resolution—and/or preferably thus creating in practice a resolution independent user interface at least on the OS with the lower resolution even if that OS does not support resolution independence on its own, and similarly preferably the refresh rate stays the same in all the OSs, which is preferably the refresh rate of the OS with the highest resolution. However, when data is sent by the OS on a pixel basis and not for example on a vectorial basis, preferably the DSP can automatically interpolate in-between data in order to make lines or curves more smooth so that in practice the resolution becomes higher even with pixel based data. Another possible variation is that for example the KVM switch in improved and contains for example similarly a DSP which can perform such automatic scaling and/or interpolation when needed and can preferably keep the resolution of the monitor for example the same as the highest resolution that is defined in one of the connected computers, thus enabling in practice higher resolution for computers that are defined with lower resolution, and thus enabling preferably a resolution independent user interface even for computers that don&#39;t support it themselves. Another possible variation is that preferably for example in a KWV system where more than two computers are connected through the same KVM switch preferably the user can for example define or configure the switching rules so that for example the audio output (or some other switched resource) will only move for example between some of the computers but not one or more other computers, so that for example it will move to the active computer for example between computer A and B but for example if the user jumps to computer C than the speakers for example remain connected for example to the audio output of the last computer which was active and do not switch over to play the audio output of computer C. Another possible variation is that for example the KVM switch preferably comes also with printer connections and support so that for example the printer can also be toggled automatically between the computers when the user switches computers and preferably the user can also enter a command with disentangles it so that the printer stays with the same computer even when switching and/or return the entanglement. Another possible variation is that preferably the bookmarks list automatically shows also near each bookmark for example the date it was entered, and/or for example the bookmarks are automatically grouped for example by days, for example with a different color for each group and/or some border marked between the groups, and then for example the date can appear once for the entire group instead of near each bookmark in the group. Another possible variation is that the user can for example tell the browser to automatically merge two or more bookmark files while keeping for example the date of visiting (and/or any other criteria) as the ordering factor. Preferably the user can also choose for example if the two (or more) bookmark files will be merged as is or for example duplicates (same urls that appear more than once) will be automatically deleted, and/or for example the user can activate (preferably whenever he/she wants) a command that deletes duplicates from the current bookmarks regardless of how the duplicates were created. When deleting duplicate bookmarks deleted preferably for example the remaining entry can indicate for example more than one creation date, or for example the date of creating the first created of the duplicates of the same url becomes the date of creation and for example the latest visitation date of the duplicates become the last visitation date, or for example the last creation date is used, since this can mean for example that the user bookmarked the url more recently in another browser and thus might be more interested in it than earlier created bookmarks, and this is especially important for example if the bookmarks are sorted according to their creation date. Preferably the user can choose between these options for example in a menu. Another possible variation is that for example when merging bookmarks and/or when activating the “remove duplicate bookmarks” command the user can preferably choose for example between removing all duplicate urls or only duplicates which have also the exact same entry time (which is what happens for example if the user imports bookmarks back and forth for example between different browsers on the same computer or for example between two or more computers), which means that bookmarking the same url at different times is not considered a strict duplicate. This has the advantage that this way the merged bookmarks list can behave as if the different browsers are sharing the same bookmarks file (and in any normal browsing the user can for example bookmark the same url twice without the previous entry being deleted), but this way the bookmarks file does not multiply itself each time the user makes two-way merges. Another possible variation is that for example if the user uses two or more different browsers on the same computer (for example MSIE, Firefox and Opera), preferably the user can tell a browser for example to automatically regularly (for example once every hour or for example once very day or any other convenient time) merge new bookmarks from the bookmarks file of one or more of other browsers (preferably the browser can automatically find the location of the requested browser&#39;s bookmark file), and so the bookmarks remain synchronized as if the browsers are sharing the same bookmarks file. Another possible variation is that for example the user can indeed tell for example Opera to save its bookmarks in the active Firefox bookmarks file or vice versa (preferably in the appropriate format), so that they can indeed share the same physical bookmarks file, for example in the way that two different installed versions of Netscape can for example share the same bookmarks file, but that is less preferable since it is more safe to have two independent copies, and also by keeping its own bookmark file each browser is not limited by the limitations of the other browser. Another possible variation is that the user can for example define more than one email account in the same browser or email client and thus choose each time for example between the available sender accounts for example from an automatic menu that shows up when composing an email message (so that for example the user can use 2-4 different sender accounts for different activities) Another possible variation is that the user can request for example to sort the list of programs in the Add/Remove programs menu according to the date and time they were added, and preferably this date and time is automatically displayed near each program there. Although Windows XP allows to sort them according to time last used, this is much more useful. In addition, preferably the Add/Remove programs menu includes also information about the path and file name of the installation file from which the program was installed, and preferably for example the indexed desktop search or the OS or some other application also automatically follows this file (for example according to some digital signature), so that if the file is for example moved to another directory the indexed desktop search or OS or other application can still locate it, and/or for example the indexed desktop search or the OS or some other application also for example monitors these files automatically and can for example report to the user if it was removed and copied for example to a cd or DVD and thus the user can at least for example know from the date in the log in which dvd or cd to look for the file if for example it was erased from the hard disk but needs to be reinstalled for some reason. Another possible variation is that preferably the user can use a search feature in the add/remove programs window, preferably click-based without having to press Enter, in a way similar for example to the Google Desktop Search. Another problem with the “Add/Remove programs” window is that if there are many programs installed, for example in Windows XP, it typically takes even a few minutes to “populate” the list, and even if the user for example closes the windows and requests for example to reopen it again for example even a few minutes later, the entire lengthy process takes place again. So preferably this is improved so that the window is preferably displayed instantly or almost instantly with the list of programs. This is preferably done for example by keeping this list in one or more files, preferably updated at all times, so that preferably each time a program is added or removed or updated preferably the relevant file or files are automatically updated with the relevant information, and so whenever the user clicks on “Add/Remove programs” preferably the list is simply read from the relevant file, and/or at least after the user opens the list preferably a copy of it is automatically saved so that it can be used when the user reopens it. This file or files are preferably constantly guarded with limited write access and/or are protected for example by encrypted and/or hidden backup and/or encrypted fingerprints in order to guard against malware messing with it. A similar problem is that for example when the user goes to the windows update web site it typically takes many minutes to check what updates or patches are needed for the user&#39;s computer. So this is preferably similarly improved so that preferably the same file that is preferably used for preferably instant access to the list of installed programs list preferably also includes the list of installed updates so that preferably this file is also used for checking which updates are already installed on the user&#39;s computer and/or which programs are installed on the user&#39;s computer (for example in cases where the applying of some patches depends on whether certain programs are installed or not), so that the check what updates are needed is preferably also done similarly preferably instantly. Preferably if the user for example needs to restore the system to an earlier state (for example in an earlier date) or for example to return forward, preferably this preferably small and preferably summary file or files that keep the information about installed programs are preferably updated automatically also, for example by keeping a copy of the summary of installed programs and/or patches also in the registry, or for example by keeping multiple versions of the file or files and for example a link from the registry to the appropriate version, which is also useful for example if the user restores the snapshot files manually for example through booting temporarily from an OS installed in another partition. Another possible variation is that for example after a boot or for example once in awhile the system for example makes sure in the background that this summary file indeed represents correctly the state of installed programs also for example according to the registry, for example by running a comparison in the background preferably for example at times when the system is not active (for example when the screen saver is activated) or for example while user is occupied with an activity that requires little disk access and/or little CPU power, such as for example while the user is typing on the word processor or for example is reading email or for example while surfing the web, so that even if an update was needed, opening the list of installed programs is preferably still instantaneous. Another possible variation is that preferably patches are applied in transactions so that for example a backlog or a copy of the state of the relevant files before the patch is automatically kept so that for example if anything goes wrong during the patch (including for example power failure, etc.) preferably the OS can automatically identify the unfinished transaction or transactions and automatically return the relevant file or files to their previous state and for example preferably try automatically or with user authorization to reapply the patch. Another possible variation is that for example while checking for updates for example with MSIE for example on the Microsoft site (which at least in the prior art without the above described improvements can take quite a few minutes), if the user for example clicks by mistake on some icon that leads to another Internet address, the whole checking for updates is stopped and even if the user presses the Back icon, it has to be restarted. So preferably this is improved so that in such cases for example the OS or the browser asks the user if he/she wants to abort the checking for updates, and/or for example the checking can continue in the background also if the user moves on to another page, and/or for example the process of checking for updates is automatically frozen for example by keeping the state of the relevant stage for example in memory or in a file and can for example continue automatically from where it last stopped if the user returns for example to the Microsoft update site in this example. Another problem is that if the user for example tries to check for patches for example from the Microsoft update site for example in one tab or browser windows and at the dame time also for example from the Office update site on another tab or window, there can apparently be problems of contest or conflict which can slow down at least one of these processes or can even get it stuck. So preferably this is improved so that for example the browser or the relevant OS service that checks the computer for installed applications and/or updates preferably automatically monitors preferably both update checks at the same time and preferably for example create a unified list and/or for example in case of partial overlap (i.e. one or more same patches appearing in both checks) preferably tells at least one of the processes to ignore it since the other process is already handling that patch, and/or if for example one of the update processes needs to lock down certain system files which the other update process also needs, preferably the OS or this service preferably for example tries to optimize the access for better efficiency, or for example creates a unified process which for example handles the patching for both of them at the same step. Another possible variation is that for example patch management software is improved so that is can for example automatically every once in a while (for example at least once a day) go over the list of installed applications and/or for example services and/or for example drivers on the user&#39;s computer and can preferably check this list against one or more preferably authoritative and secure databases on the Internet, which preferably contain information at least about critical security updates in such applications and preferably about where to get them from, and so the software can preferably automatically create a list of the applications and/or services and/or drivers which need to be updated for security reasons and preferably can display this list automatically to the user san/or save it in a file and/or for example automatically download for example at least the most critical patches and install them, for example automatically, or for example after requesting the user&#39;s permission. Another possible variation is that for example programs that try to protect deleted files while there is sufficient space, such as for example Norton, and/or for example even the OS itself, preferably can keep for example in or near the entry of deleted files in the directory (or elsewhere—for example in a cumulative log that covers multiple files) the name of the application that deleted it or the user interface from which it was deleted and/or the time and date it was deleted. Another possible variation is that preferably the instant desktop search (such as for example the Google desktop search) preferably shows automatically also the drive letter and/or the path of each result (preferably directly in the list of results) at least of there are duplicate (i.e. for example the same program installed in multiple places), or for any results. Another possible variation is that for example the word processor has special icons for various saving options, such as for example an icon for saving a copy of the file on CD and/or for example an icon for saving on diskette or for example other removable media (and preferably when clicking on such an icon the word processor preferably saves a copy of the file with the same name on the CD or other removable media and preferably also for example automatically saves at the same time also on the default directory hard disk in order to keep the synchronization between the hard disk and the backup), and/or for example an icon for “save as” (the normal icon is for saving under the same name), and/or for example an icon for “save with automatic increment”, as explained elsewhere in this application. Preferably when clicking for example after that on ̂S, preferably the file is automatically saved also on the back-up or backups. Another possible variation is that this does not change the behavior of ̂S or for example when clicking again on ̂S the user is asked if to save it also on the backup, or for example the user can toggle between these options for example by clicking on some icon or menu option. Another possible variation is that for example also in opening files, for example in the word processor or in the browser, preferably the user can for example type the main identifying string in a group of similar-names files which are a cumulative increment of each other and/or for example pick it from an automatically displayed list (as can be determined for example automatically for example by the word processor for example by automatically keeping tracks of these increments for example each time the file is saved with a new name and/or for example by automatic identification of the identical or almost identical name except for the incrementing number and/or according to the time and date stamp, so that the user can for example request the word processor to automatically select and/or open the relevant file with the largest number and/or for example with the latest time and date stamp and/or for example the word processor can for example automatically warm the user for example if the latest time and date stamp does not match also the highest number in the incrementing series. Another possible variation is that preferably the dialogue box for saving files and/or the dialogue box for opening files preferably show in the top area that indicates the directory—preferably also at least the drive letter and/or the path, because otherwise if there exists more that one directory with the same name the user cannot see immediately which of these directories it is (in the prior art for example in Windows only the directory name is displayed without path info or drive letter), and/or preferably also show for example in the files list the file sizes and/or dates and/or time of creation or last modification—for example like the dir command in a cmd window. Another possible variation is that for example in 2 nd  hand bulletin board sites (such as for example www.yad2.co.il. for example in at least some types of items in which the selling user did not include photographs the server for example automatically inserts a link to at least one photograph of the relevant item for example in the manufacturer&#39;s web site. This can be done for example by the server automatically searching for example in the web sites of car manufactures for example for at least the most common models and preferably finding automatically the relevant photographs, so that for example at least in some listed items where the seller did not for example include a photo of the car being offered for sale preferably the server can include automatically a link to at least one photo of for example a car of that model for example in the manufacturer&#39;s site. Another possible variation is that the server can for example in at least some of these cases for example also automatically convert the color of the car in the photo to the color of the car published by the seller, for example by automatically creating a local copy of the photo and automatically identifying the contour of the car and automatically changing its color to the offered color if the color in the original photo is different, and/or for example there are coded commands which can tell the browser to do the color conversion automatically.   3. Preferably the OS allows the user to access at least one CD-ROM drive (and/or dvd drive) even when the OS is started for example in “safe mode”, otherwise it can be very frustrating when the user might not be able to fix various things for example because he/she cannot fix anything from the installation CD while in safe mode. Another possible variation is that preferably at least as one of the options (but preferably by default) safe mode starts with the correct display driver loaded and so preferably uses the normal resolution and/or refresh rate which the user uses normally (for example unless the user explicitly requests otherwise or for example a specific problem with the display driver is automatically detected) and/or at least preferably uses by default a resolution of at least 75 Hz or more preferably at least 85 Hz and/or preferably at least a higher resolution than 640×480, since otherwise working in safe mode can be slow and painful to the eyes without justification. Another possible variation is that at least after the safe mode boots the user can preferably increase the refresh rate and/or the resolution while in safe mode, so that preferably it is lowered again only if there is for example a problem with the display driver which causes this mode not to work properly, but as explained above more preferably the safe mode boots like this by default, for example unless for example there is a problem with the display driver. Another possible variation is that preferably if for example the user for some reason still chooses to use safe more with a lower resolution than the normal resolution he/she uses in normal boots (or for example it becomes necessary for example due to a problem with the display driver), preferably any changes made in the arrangement of icons on the desktop are preferably automatically undone when the user returns to normal mode and/or at least the user is preferably at least automatically offered the opportunity to automatically restore the icons to their normal arrangement. Another possible variation is that for example any change in resolution that results in a changed arrangement of the icons is preferably automatically un-doable for example automatically upon return to the previous resolution and/or by offering this option to the user. Preferably this is done by saving automatically the relevant information about the arrangement of the icons on the desktop preferably separately automatically for each resolution, and if for example the users adds or removes a specific icon and/or installs or uninstalls the relevant application, preferably this can be taken into account for example after restoring the previously saved arrangement. Preferably the undo option is available anyway for any changes in the arrangement of the icons, preferably by saving automatically a rollback log of such changes, preferably by the OS (and/or preferably the user can also save various specific arrangements of the desktop as various snapshot points), as explained elsewhere in this application, which is preferably done independently of the various System Restore Checkpoints. In addition, if for example the OS becomes unstable or cannot complete a boot for example because of a problem with some driver, preferably the system is able to automatically remove and/or ignore and/or report to the user the driver that is causing the problem. Even if the problem for example crashed the computer completely so that the OS could not report anything, preferably during each boot the system for example keeps a log of all successful steps in the boot, and so even if a certain step causes a crash so that the system can&#39;t even report the problem, preferably in the next boot the system knows by the incomplete step in the log exactly where it crashed the last time and can preferably automatically complete the boot this time without the problematic step and preferably reports to the user exactly what the problem was and/or preferably automatically removes the problem and/or offers the user for example to chose among a few possible corrections to the problem so that the problem does not occur at all again after that. Another possible variation is that various data (such as for example the condition of the CPU, heat, various memory parameters and/or other parameters) are constantly kept at preferably small intervals, for example in one or more circular buffers, and preferably for example a special mark is added to the current position of the buffer after each new boot, so that if for example the system crashes for an unknown reason and resets (for example even while being unattended), the user and/or the OS can automatically know after the next boot what caused the crash. Another possible variation is that whenever the system crashes these parameters are automatically saved for example by some special application that preferably runs below the OS and can still perform this operation even if the OS is completely stuck. This application can for example also be responsible for an automatic reset if it senses that the system has indeed crashed or got stuck or for example if it senses that the CPU or some other element or device has become too hot or is otherwise dangerously malfunctioning (in which case preferably an automatic shutdown is activated instead of an automatic reset), and/or for example some special hardware element is responsible for that. Of course, various combinations of the above and other variations can also be used.   4. On the other hand, preferably the user can disable the Autorun feature that enables programs on CD&#39;s to start running automatically when the CD is inserted into the computer, preferably without having to disable for that the Auto insert notification for that drive, since this feature is very unsafe in terms of security. In the prior art the user can disable this in Windows only by disabling also the auto insert notification, which is not desirable, since disabling the auto insert notification can cause other problems.   5. Preferably the Windows OS allows executing files in DOS (CMD mode in Windows XP or NT) also by clicking on or near their name instead of having to type it. This is very important for example in Windows NT or XP, since, unlike for example Windows 98, the user has to type the whole name of the command instead of being able to type also instead only the 8 character DOS name of it. Since for example in Windows NT and XP the user can in DOS mode click on the mouse in order for example to mark a name for cut and paste, preferably the execute command is added for example to the menu of these available options. (Of course there are programs that can be used for example for automatic file completion, but this is another option that allows more flexibility and convenience to the user). Another possible variation is that preferably the log of screen output in DOS or CMD windows at least when the user is in the normal shell mode is preferably kept automatically in a log or buffer, so that for example the user can use for example a lever for example at the right of the DOS or CMD window which preferably allows the user to go back and see for example the previous lines that were scrolled out, preferably for example until a limit of a few thousands of lines (or any other reasonable limit, which can preferably be changed by the user), and/or for example until the beginning of the open session with that DOS or CMD window.   6. Preferably the OS itself and/or various relevant applications can display for certain activities approximately how much time it is going to take and/or for example the percent completed and/or the percent remaining—even if these are complex activities such as for example when scanning for viruses. Although many applications do give such information—these are typically applications that deal with a single file or a pre-specified list of files, whereas for example virus scanning programs do not, which can be aggravating to users, since such activities can typically take for example anywhere between 5-20 minutes. So preferably the relevant applications and/or the OS can automatically calculate for example the number of files and/or their cumulative size (preferably of course only for the relevant types of files that are to be scanned), and thus for example the application and/or the OS can display to the user an estimate of time and/or percent done and/or percent remaining. Preferably this is made available for example also to the application&#39;s programmer, for example as an OS function that can return for example the total number of files of a certain type and/or extension and/or their cumulative sizes, for example on the entire computer or for example on a given drive or directory (preferably automatically including all of its sub-directories). Another possible variation is that if the user for example aborts a virus scan and later wants to continue, the program can automatically continue from the last point reached. This can be done for example by saving the position in the directory structure and continuing automatically from there, preferably for example if the time since the last scan is no longer than a certain time (for example 1 hour or any other reasonable time gap), and for example if the time gap is bigger then preferably the program asks the user if he/she wants to continue from the same point or restart the scan. Another possible variation is that preferably for example one or more components of the OS or for example of the security system or some other application or service can preferably constantly monitor the file system and update some table or database about all the changes to the hard disk and when they happened, and preferably this information can be coupled to the virus scanning activity so that preferably, at least as one of the available operations modes, but preferably by default, the antivirus scanning program preferably at least in normal global virus scans preferably automatically checks only files or directories or disk areas that have changed since the last scan instead of scanning all the hard disks again and again, for example if automatic global virus scan is scheduled for example every day, because otherwise if the user has for example a huge amount of data the antivirus scan would go on and on almost all the time, significantly slowing down normal activities, while in reality typically only a very small percent of files have actually changed or are new since the last virus scan. If for example a rollback log or logs are automatically kept for undoing changes in the disks, as explained elsewhere in this application, then preferably this log is also used for directing the antivirus application or applications to check only files or directories or disk areas which have really changed since the last check. Similarly, if for example Copy-on-write is used in the file system, for example for virtualization or for example in a file system that is based for example entirely or mostly on copy-on-write, then preferably the information about the actual changes in the disk or disks is used by working with the components that handle the copy-on-write, so that preferably the at least for the disk areas that are covered by the copy-on-write the antivirus program has to scan only the parts that changed with the copy-on-write. Preferably the interface with the antivirus application is done for example by improving the antivirus program to take such information into account and/or for example by the Security System or the OS automatically directing the antivirus program automatically only to the relevant files or directories or disk areas (for example by making it appear to the antivirus application temporarily as if the only files that exist are those that have changes since the last time, and/or for example by defining a standard interface, such as for example some standard table or database, which the OS or the security system updates with information about files and/or directories and/or disk areas which have changed since the last antivirus scan for example listed according to time frames, so that the antivirus program can consult this interface when deciding what to check in its virus scan. Of course the rollback log or database or log of the copy-on-write changes or the interface table for the antivirus programs is preferably automatically preferably highly protected for example by restricting write-access to it for example only to the OS or to the security system and/or automatically backed up for example with encryption and/or fingerprints so that it cannot be tempered with for example by malware. Another possible variation is that for example the antivirus program can scan for example in each normally scheduled global scan only files or directories or areas which have changed since the last scan as determined for example by their time and date of last changed as indicated by the normal file system, but this would be very dangerous for example if some virus or Trojan horse changes files without changing their last change time &amp; date stamp or with a forged time or date, so preferably if this is used it is preferably accompanied for example by disallowing any changes to the disk with an incorrect time and date at least without user permission, which is preferably enforced, again, for example by the OS or by the security system, and in this case preferably an automatic log is kept also for example of any changes in the time and of the system, and/or for example the OS or the security system requires user authorization for such changes. In addition, the above variations are preferably accompanied by at least some component of the OS and/or the security system which is activated automatically also if the system is booted for example from a diskette or a CD or DVD or for example some other partition or disk or some other source, as explained in other applications by the present inventor, in order to monitor changes even in cases of such other boots, otherwise the file system or OS or security system integrity can no longer be ensured. Another possible variation is that for example the antivirus program can consult also the change tables of the OS or the security system on other partitions if the user for example boots from another partition. In a system that runs multiple OSs simultaneously for example with a hypervisor such as for example vanderpool or similar systems, since preferably the copy-on-write is run by the hypervisor, preferably the antivirus preferably communicates with the system that runs the copy-one in the hypervisor and preferably when booting from another device the part that is active anyway is preferably the Hypervisor or part of it or associated with it, and preferably the hypervisor also makes sure that no OS starts an antivirus scan while an antivirus scan is being run by another OS or for example makes sure that antivirus automatic scanning is scheduled at most only in one of the OSs, since running two or more such antivirus scans at the same time on separate OSs would be very inefficient.   7. Preferably commands such as for example “copy” or “xcopy” or similar commands are extended so that multiple destinations can be used, so that for example xcopy “bet*.doc 1: n:” will copy all the relevant files to all the destination drives/directories, and/or for example preferably multiple file parameters can be used in the same command, such as for example ‘xcopy.doc &amp; *.pdf 1:’ (preferably the ‘&amp;’ or for example ‘,’ or other operator indicates that the doc files should not be copied over the pdf files in this example but both are to be copied to the indicated target drive). Also, when copying to multiple destinations (for example 2 or more separate drives or partitions or directories) at the same time, preferably the OS also works more efficiently, so that for example multiple files and/or sections and/or sectors are preferably copied at once each time (for example until the memory buffer is full), and are then preferably copied from the same read operation to all the destinations before going on to read the next group of for example files and/or sections and/or sectors, etc. Another possible variation is that such multiple destinations can also be specified for example when copying through the windows explorer, and in this case preferably for example the user can preferably press for example the Control key or Shift key or some other key in order to mark for example with the mouse multiple destinations without the previous marks being removed. Another possible improvement is that preferably when copying a large group of files (for example from one directory to another, for example in a DOS or CMD window—for example with ‘copy’ or ‘xcopy’, or with the Windows explorer) the user also has an option of “No to all” or for example “Never” if he is asked if to overwrite files with the same name, so that preferably only files that don&#39;t exist already in the target directory are copies and preferably for higher speed the file names that have been skipped are not shown on the screen during the copy process. In the prior art the user has to answer this for each file that has the same name individually or can choose “yes to all” but there is no “no to all” option. Another possible variation is that preferably when copying for example directories between partitions for example through the Windows Explorer, preferably the OS shows the also drive letters on both sides of the typical animation that shows data flowing between directories. In addition, preferably for example when copying large files for example in a DOS or cmd window preferably the OS shows also the progress for example in percentages and/or for example with an advance bar for example like in the explorer.   8. Preferably various Undo commands are applied also to various memory related commands where they do not yet exist, so that for example if the user works with an Internet browser and presses a “clear form” button, preferably the user can undo it for example by pressing control-z or for example pressing for example some undo button for example on the browser. Similarly, preferably the browser itself keeps in memory for example recent changes to various form fields in the same page and/or for example also on previous pages, so that for example jumping back to a previously filled field on the same page or for example also on previous pages will still allow the user for example to undo changes in that field, for example by pressing ̂z. Another problem is that for example browsers can remember various form fields in order to fill them automatically for the user, but for example Netscape and MSIE remember only according to searching for keywords in the simple text near the field and remember only the last value. Therefore another possible variation is that preferably the browser (or other application) can remember preferably automatically more than one value for each field—for example the last N values, so that for example if the user is not satisfied with the automatically inserted value he/she can preferably for example use the mouse or arrows or other keys in order to scroll back to other previously filled values. (This scrolling back can preferably be activated for example for the current field or for example for the current section or for example for the entire form). Another possible variation is that the browser (or other application) can preferably remember preferably automatically also more complex structures, so that for example if a form contains a name filed or address or phone or other types of fields in multiple places (for example the form at https://strategis.ic.gc.ca/secure/cgi-bin/sc_mrksv/cipo/patbrev-filing/patent.cgi, which contains such fields in different sections, for example “4.1 Applicant”, “7. Patent Agent or Associate Patent Agent” and “8. Canadian Representative”), so preferably if the user has previously used different values for example for the name and address etc. in the different sections, preferably the browser preferably remembers also the values per section, and if the user later uses again the same or a similar form preferably the browser suggests to the user the appropriate recently used values according to each the section. Another possible variation is that the browser can for example let the user access, for example with the arrows, any recent values that were entered into form fields regardless of the field or the form, so that for example, at least as one of the options, the user can for example simply scroll back to any of the previous or at least the last values (for example any of the last 50 or 100 or other reasonable list size limit) which he/she typed and use any of them. Another possible variation is that the browser can for example automatically identify search line fields (for example by reading the text of the button next to the field and/or by knowing for example the sites of the main search engines and can enter for the user by default for example the most recent search field, so that for example if the user wants to search for the same thing in more than one place the browser can automatically save him/her typing. Another possible variation is that the browser or the OS or the security system preferably warns the user and requests his/her authorization whenever some program tries to install or register itself as a plug-in for one or more browsers. Another possible variation is that preferably the browser or the security system or the OS preferably warns the user (at least the first time) whenever a browser plug-in tries to access an online form which the user is filling—since there are malwares which install themselves as browser plug-ins in order to steal data when user is fills forms. Another possible variation is that when the browser for example asks the user if to install some plug-in preferably the user can also, preferably as one of the options, tell the browser not to ask again about plug-ins of that type or general type. In addition, preferably, as explained also in Canadian applications 2,455,342 of Dec. 17, 2003 and 2,452,778 of Dec. 29, 2003 by the present inventor, preferably the HTML command set and/or for example the Javascript command set is improved, so that preferably it is possible to define for example which button (or buttons) will be activated by default for example if the user presses for example the Enter Key and/or for example the Space Key, and/or for example what action (if any) is to be performed when various keys are pressed. Preferably the keys can be linked for example to Javascript buttons for example by a definition in each button (however, if for example in more than one button the same key is defined as activating the button then preferably there are rules that define which button overrules), and/or for example additional commands are added (preferably within HTML tags that define directly various actions that can be performed and/or buttons that should be activated when a certain key is pressed). This is very important since for example in standard HTML forms there is a problem that pressing the Enter key for example when an input text line (or even for example a radio button or a checkbox button) is in focus can cause the form to be submitted. Sometimes this is undesirable (for example when the user is required to fill a form with multiple items), and in the prior art the only solution is adding various Javascript checks and issuing error messages for example if there are still empty fields. But if the user pressed enter for example after filling in a text line and did not intend to submit the form, such messages are aggravating. So preferably to prevent this, the above additional commands can be used for example to generally define for example that pressing the Enter key for example anywhere in the form (for example by adding the appropriate command within the “&lt;form . . . ” tag that appears at the beginning of the form or for example within the tag that defines the submit button) will have no effect or at least will not cause the form to be submitted, or for example this can be defined in specific fields (for example within the tag that defines the field).   9. Another problem with Internet browsers is that in some cases lines are truncated when printed, which can happen sometimes for example when forms or tables are used. In order to prevent this, preferably the browser and/or the OS and/or the printer driver (and/or of course for example any other software) preferably automatically check if this is about to happen (preferably by simulating the printed page into memory and checking the representation of the results) and, if so, this is preferably automatically prevented, for example by automatically converting to landscape mode, and/or by automatic additional line wrapping if possible (for example, if it does not damage a format of a table), and/or for example by automatically reducing the left and/or right page margins and/or by automatically reducing the font size (for example just in the horizontal dimension or both horizontally and vertically, in order to keep the aspect ratio), and/or for example informing the user about the problem and asking him to choose from a number of possible solutions (such as for example any of the above described solutions) and/or allowing the user for example to decide to truncate less important parts on the left of the pages (for example if the user is printing an article and the left column for example contains only links and/or advertisements and/or irrelevant images). Another possible variation is that the user can for example mark just part of the displayed HTML page (for example with the mouse)—for example just a specific column, and then use a command that prints only the marked area. Another possible variation is that the user does not even have to mark the entire area (which can be annoying for example if it is a long page) but can for example simply click for example on the relevant column (typically the middle column) and for example then print only the relevant column or columns till the end if he/she so desires (for example as one of the print options or for example by right clicking with the mouse on the column and choosing from a menu automatic marking of the column till its end and/or printing of only the column which was clicked upon till its end as one of the options, or for example using a control key or keys or clicking on an option or icon which automatically marks the column till the end). Another possible variation is that for example when the user prints for example a web page the browser for example automatically offers a number of possible printing options such as for example print the entire page or print for example just the main column or columns or the column which the user last clicked on, or the column which the mouse currently hovers on, etc. The browser can preferably automatically identify the main column or columns (for example by finding the largest consecutive sections that contain mainly text, and/or by checking for example first of all if the middle column is indeed the main one and/or offering it to the user as default and asking him/her to confirm, since that is usually the case). The Opera browser for example prints only the marked section in a web page if a section is marked but does not allow automatic marking or printing till the end of the column or choosing if to print just the marked section or all the page. Also, if the user for example searches for a word or word combination in the page it becomes marked when found and then when printing Opera prints only the marked word or words. So preferably this is improved so that text that was automatically marked for example as a result of a search does not automatically cause the printing to be limited to just the search word or string since it is very unlikely that the user intended this (preferably the browser remembers how the word or words got marked and preferably also takes into account the number of words marked). And also, when printing only a marked section Opera does not print the url but only the page title, whereas as explained below preferably the url is also printed automatically of course, and also when printing only the marked section the Opera browser prints just text and ignores any formatting information, including for example html links (which are typically blue with underline), and so in the printed version only normal text appears instead of the link, so when reading the printed page the user is even not aware of the links that were in the page—which is clearly not properly printing the column (unless the user for example explicitly wants such a thing). Of course in the current prior art the user can for example mark an area in the page that is displayed by the Internet browser and then use copy and paste and print it for example from Word (when using cut &amp; paste to copy web pages from most browsers—for example MSIE, Netscape and Firefox—the copy usually transfers of course also images and page formatting, including the links), but the above option allows the user preferably to do this in a faster and more convenient way, and also at least the url address is preferably automatically also printed, even if only part of the page has been marked and printed. Another possible variation is that for example at least the headline and/or logo and/or first few lines of the page are also printed automatically, for example with some mark that indicates the jump between that till the marked section, since this can give the user a better feel of identifying later the page from which the extract was printed. In addition preferably the user can also mark multiple sections in the same page, for example by pressing the shift or control key or some other key while marking with the mouse a new section, so that the previous marked section or sections remains also marked, and/or for example after marking a section (or for example even without marking one or more sections) preferably the user can for example “unmark” or unselect” one or more sections or images that he/she does not want printed, such as for example if there are one or more large images that are advertisements for example in the middle of the desired column or for example to the side of it. Preferably this is done for example by right clicking on the undesired image or images for example with the right mouse button and selecting from a menu an option to ignore it while printing (preferably this option is used for example if the user wants to print the entire page excepts for example one or more large images or advertisements), or for example after marking a section which includes the undesired image, holding for example the shift key or control key and then clicking with the mouse on one or more marked images, and thus unmarking them while leaving the rest of the desired area still marked. This is very important, since it can be very annoying for example if the user can mark a single column, which will print properly with all the normal images and links, etc, but cannot get rid of annoying large advertisement images which can for example waste a lot of ink on inkjet printers. Another possible variation is that for example at least by default the browser automatically unmarks images which are labeled as advertisements, so that they are preferably automatically not printed for example unless the user marks them explicitly for printing or changes this default. Recently (a long time after this feature was already included in prior applications of which this application is a CIP), Microsoft indeed added to the Beta of MSIE 7 the feature of printing only the marked area when there is a marked area, and without the loss of images or text formatting within the printed section, and including the URL. However, both Opera and MSIE for example enable only marking one consecutive section in the web page, and in MSIE this means for example that the user cannot get rid of undesired images—for example advertisements—within the section that the user wants to print. (Also, like Opera, MSIE does not ignore the marking of a few words due to searching for one or more words, as explained above, and thus will print just a few words in such a case). Another problem is that in MSIE this works only if the user chooses the option of “print the selection” explicitly again each time when printing, which is very inconvenient. So preferably this is improved so that for example after the user chooses this once, this preferably remains the default option preferably for any additional printings from the browser, until the user for example unselects this or chooses for example “print the whole page” or something similar and/or printing the selection is preferably the default also to start with. Another possible variation is that the user can for example also get rid of annoying advertisements for example on the screen display (which can be very annoying for example if the use and endless cycle of flashing colors or lights) for example by marking the area of the advertisement with the mouse and/or clicking on the image with the right mouse menu and then choosing for example from a menu to hide this image for example now or whenever it appears again also on other pages and/or for example the user can tell the browser in this image or in general for example to automatically not show any recycled flashing (and in this case preferably the browser identifies such flashing automatically by analyzing the cycle for example in flash files or animated gifs or similar formats that might be used in this way). Another possible variation is that preferably the web browser preferably enables printing just an image in a web page also directly without having to first open it or marling it, for example by allowing the user to right-click on an image with the mouse and then chose an options that directly prints for example just the image (which can be faster than for example marking the image with the mouse and then requesting to print the selection, unless the user wants to mark multiple images and print them together). Another possible variation is that when the user requests to print for example a marked column and/or for example even when printing a whole web page the browser for example asks him/her if to print it with or without the images, but of course at least the links are preferably always printed properly as links even when printing without the images. In addition, preferably the user can tell the browser for example if to print the chosen column with the original width of the marked column or for example to automatically expand it to make better use of the width available, preferably without changing for example the original separation into paragraphs (preferably this automatic widening is the default, since otherwise it still wastes more pages and much of the advantage of printing only the marked column is gone) and/or for example it is printed at the best width and the user cannot change that. As explained above preferably apart from preferably automatically widening the column to fill the page, preferably all the other formatting such as for example marked links, text color, font type and size, etc. is kept as the original (or for example the user can choose differently for example when printing or by changing some parameters for example in the print menu). This means that preferably for example if the paragraph ends with &lt;br&gt; after every line then preferably these &lt;br&gt; controls are automatically removed or relocated and/or for example the browser identifies automatically the paragraphs (for example by finding an empty line between them and/or by finding other commands which can separate paragraphs) and preferably respects the paragraph separators but ignores other commands which are used for line breaks. Another possible variation is that for example when printing the browser asks the user for example if to print backgrounds of text which are non-white as they are or convert them automatically to white (and/or for example the user chooses this once as preferences and it stays like that until the user changes this). Another possible variation is that preferably if links are for example marked by blue or some other color without the normal underline (as is done for example in all the Wikipedia pages) or for example marked with an underline but an unconventional color, preferably by default the browser automatically adds the underlines (and/or for example corrects the color for example to the convention of blue for not yet visited links and purple for visited links) for example on the screen and/or when printing the page, and especially for example at least adds automatically the underline if the printer is a black and white printer, such a for example a non-color laser printer. In the prior art when printing for example Wikipedia pages the links don&#39;t even show in blue on color printers, so preferably the browser at least by default automatically disregards any commands which can cause this and/or simply automatically adds the color and/or underline to the links when printing, regardless of the commands which prevented it. Another possible variation is that preferably—since Wikipedia pages keep anyway an automatic history of when each change was made—preferably this information is used to display automatically (at least as one of the options but preferably by default) the date each section in an article was entered—preferably when the user hovers over it with the mouse, and preferably this is displayed on the side margin so that it does not cover any text and does not disturb the reading. Another possible variation is that the user can also request for example when printing to expand the links, which means that preferably the browser automatically adds near each link in the printout also the url (for example in brackets next to it). Another possible variation is that preferably the user can also apart from printing for example save the currently marked sections together in a file (preferably, like in the printing, including at least the title and the URL and preferably also the headline or headlines) or for example send them to a cumulative open file or window or tab where they are added cumulatively (in this case also preferably each such marked sect group of section is preferably automatically added with the title and url at the beginning of it. Another problem is that for example Opera and MSIE enable the user to save a web page in a way that saves also its images only if the user has opened the page itself and not if is saved by right clicking on the ink and requesting to save its target. So preferably this is improved so that for example when right-clicking on a link the user is offered for example one option to save the target including images and one without it or for example the images are automatically saved also in this case unless for example the user changes some general flag that enables or disables it. Similarly when clicking for example on a marked group of links as explained elsewhere in this application, preferably the same is done automatically for the entire group of marked links, and preferably they can be also saved either as multiple files or as one consecutive file (for example if the user wants to save chapters from an ebook which are each on a separate page into a single file, and/or for example also the normal save-as option in the browser&#39;s menu can either save on a new file or add to a cumulative file). Another possible variation is that the browser enables the user for example to normally click (or for example to right-click and choose from a menu) also on html addresses within the web page which are not links (i.e. appear as simple text) and thus open them for example in a new tab or new window. Opera for example enables this only if the user marks the link, so the above variation is better and faster. Another possible variation is that the browser also automatically shows such html addresses as normal links (as if they have been defined with the normal href tag) for example with the normal typically blue underline convention, or for example with a special color or other identifier that indicates that this was not officially defined as a link in the page. Another possible variation is that the user can for example mark any set of words in the text of the web page and then can for example right-click on it with the mouse and then preferably one of the options in the menu that appears is to open for example a new search tab (or window) with these words, wherein the default search engine&#39;s is preferably pre-defined by the user (for example http://google.com) and preferably stays like that as default until the user changes it again. (For this preferably the browser opens the search page with those words added after a “?” to the url of the search engine, however since the format of the query might be different for various search engines preferably the browser has in advance pre-defined information about the correct query format for accessing at least the most common search engines and/or can get automatic updates about that for example from the site of the developers of that browser. Another possible variation is that this data contains also information or templates for processing the search results from these engines and so preferably the user can also request the search from more than one search engine at the same time and thus the browser preferably does for the user the integration of the results like a meta-search engine. Another problem is that if the printer for example gets disconnected by accident for example Windows does not show any warning and the user might try to print and not understand why nothing happens. So preferably this is improved so that the OS automatically warns the user for example if its device detectors can&#39;t find any printer attached and/or for example the OS or application and/or printer drivers warn the user if he/she tries to print into a device that is not currently connected. Another preferable improvement is that for example the browser or the printer driver shows the number of pages that will be printed before the user starts the actual printing. (For example the browser can show the logical division of pages if the Internet page will be printed (preferably by showing automatically the page borders and/or numbers for example by default and/or when the user presses some control) or at least show the total number of printed pages at the bottom of the page display on the screen, or for example when the user presses Control-P, preferably the print dialogue window shows the projected number of pages that will be printed). In the prior art the user had to start the printing of normal html pages in the browser and wait till the first page has been printed in order to see on the first page how many pages will be printed from the displayed Internet page. In addition preferably the user can easily reduce or increase the size of the printed fonts, for example by a specific command when printing (or for example by changing defaults for example on a configuration or preferences menu of the browser, such as for example “large fonts on print”, “save on pages when printing” or for example defining specific font sizes which preferably affect for example the fonts of the main column, which is preferably identified automatically by the browser, as explained elsewhere in this application, and/or affect the fonts which have the highest occurrence on the page, and in that case preferably the other fonts are automatically reduced or enlarged with the same proportions), or for example by reducing or increasing the size of the fonts on the screen so that this affects automatically also the printing (however, if this is done then preferably it is done with appropriate conversion preferably for example by reducing or enlarging at the same factor compared for example the default printing size which would have been used normally, since obviously in general the user needs larger fonts on the screen than on paper since the resolution and contrast of the printer are typically much better than the screen). In the prior art for example in Netscape the user can reduce or increase the font size of web pages on the screen by pressing Control+ or Control-, but these changes have no effect on the printing of web pages, and also they affect only the fonts and not the images. Preferably this reducing or increasing of fonts can be also done for example for a specific web page and/or for a specific site instead of Globally, since for example in Netscape the changed size remains also when the user moves to other web pages (however preferably the browser remembers the changed size of the page or for the site for which it was made). Another possible variation is that the same command that reduces or increase the font size on the page (and/or another command) can cause also the images to automatically grow or shrink in addition to or instead of the fonts, and this preferably also affects also the printing (for increasing the image sizes, preferably the images are vector-based images (for this preferably for example the jpeg or gif formats or some other format or formats are improved to save normal image files automatically as vectorial data, at least as one of the options, for example like a single frame in an avi file), or for example the browser simply enlarges them eventhough the resolution remains the same, or for example the http protocol is improved so that images are automatically saved by web servers and/or by relevant web authoring tools in more than one size and for example the browser can automatically request the same image again with some parameter that tells the server to send it in a larger size and then the server automatically sends again the same image in a larger size. If the last variation is used then it means that preferably the web page designer includes an image of higher resolution and preferably the web authoring tool or the web server and/or the user&#39;s browser can automatically generate also the reduced resolution versions). Preferably when the user for example increases or reduces the size of a web page (preferably both fonts and images, as explained above) or for example Word (or other word processor) documents (and/or for example if the user moves from partial window to full screen or vice versa, or for example accepts changes in the Word processor), preferably the browser (or other application) preferably automatically keeps the point that was at the cursor (i.e. preferably the point over which the user hovered with the mouse at the time of making the enlargement or reduction or for example during the N seconds leading up to the point of making the enlargement or reduction—which is most preferable since it is usually a very good indicator of the user&#39;s center of attention at that time) or at the center of the screen (or for example a few lines above the bottom of the screen or about a third of the size of the vertical screen from the bottom, which is many times the typical current reading position) at preferably more or less the same position after the reduction or enlargement (and preferably similarly also for example if the user increases or reduces the line spacing or the font size or the margins or for example makes other changes which change the page size), so the current center of attention preferably remains more or less at the same place (or preferably at least makes sure that it does not run out of the screen). This means that preferably the up-down position of the center remains the same, and preferably for example if a horizontal lever for moving right-left is created then preferably the center also remains more or less at the same place in terms of right-left or at least does not run out of the screen into the margin. In case of web pages the cursor position is preferably determined for example by the vertical and/or horizontal position of the mouse, since usually the user keeps the mouse pointer at approximately the text area which he/she is currently reading, and/or for example the word that is currently at the center of the page is considered the current position and/or for example the position which the user last hovered over with the mouse or last clicked on with the mouse is considered the current position (for example if the click has been within a certain short enough time window from the time of enlarging or reducing the page), and/or for example if there is a central column then preferably the central column is automatically identified and the enlargement automatically preferably keeps the sideways center of the column or the point which was at the position of the mouse at the same position sideways as the text expands to the right and to the left (and/or for example the left border of the central column is kept at the same position in case of left-to-right languages and/or for example the right border for example in case of right-to-left languages), and/or for example if a word or a section is marked (a marked word or few marked words would typically means the result of a search) then preferably the word or group of words is considered to be the center (and if it is for example the size of a few sentences or a paragraph then for example the center of the paragraph or its beginning is considered to be the center, preferably depending also on its position on the screen for example before the enlargement and/or for example the position of the mouse, etc, as explained above), and/or for example a sensor is used which tracks the user&#39;s eye movements. Another possible variation is that preferably the user can also for example activate a command which reduces or enlarges the fonts and/or images for example for all the open tabs at once or for example for multiple tabs instead of having to do it for each tab individually. Another possible variation is that preferably when changing for example from user mode to author mode or vice versa for example in the Opera browser, preferably only the background color and/or fort color changes (and/or for example even choosing for example a default user-preferred font size and/or font type at least for the main text, wherein the main text is preferably detected automatically for example as the text of the main column and/or for example as the font size which composes most of the text in the current web page, and if it is increased or decreased then preferably fonts of other sizes are also increased or decreased proportionally) but preferably there are no other format changes (this is better than the prior art since currently for example in opera 8.5 and 9.0 switching between these two modes can also make many other changes in the format in which the web page is displayed. Another problem is that when printing for example a web page which contains a background other than white, the printed page might appear too dark or hard to read or too much ink is wasted for example if it is an inkjet printer. So preferably this is improved so that when printing a web page (for example in general or at least if the background is for example darker than a certain threshold (for example according the bgcolor command or for example if it is based on an image then for example by calculating the average darkness of the image), preferably the browser automatically prints the page without the background color or pattern and/or for example automatically asks the user if he/she wants to print it with or without the background preferably when the user requests the printing, or this appears for example automatically as one of the changeable defaults on the print dialogue when the user presses for example ̂P. Another problem for example in Opera is that after the user for example enlarges (or reduces) the font (and/or the image size on a web page) and/or changes from author mode to user mode or vice versa, the changed size and user/author mode is kept also if the user opens in the same tab (or even in new tabs opened from this tab) links that are entirely unrelated (for example by clicking on a link or by typing a new url in the url line) or for example goes back to a previous unrelated page in the same tab, which can be very inconvenient because usually the user changes the size and/or the mode only if there is a specific problem in some page or site and this might be usually not desired in other sites. So preferably this is improved so that changes in user/author mode and/or in font size are preferably reverted back automatically for example at least if the user moves on to a different domain and/or goes back to a previous page which the user viewed previously before making the change in size and/or in mode, and/or for example even when the user moves to another page in the same domain, at least if that page has by default a different font size than the page in which the user changed the size. Another problem is that when increasing or reducing the size of the fonts and images of a web page for example in Opera or in MSIE (typically by holding the control key and rotating the mouse&#39;s wheel upwards or downwards) it takes a lot of to see the change time if the file is big. So preferably this is improved so that preferably (for example in general or at least if the file or web page is beyond a certain threshold size, for example would what be equivalent to 20 printed pages or more or other reasonable threshold) when such increase or reduction is done preferably the browser first changes only the current section of the page which is visible on the screen (preferably centered around the center of the page as determined for example by any of the above variations as explained above, such as for example centered around the text that was at center on the screen when the reduction or enlargement was performed or the centered around the text that was found by a search or the last text on which the user clicked the mouse or for example was hovering over with the mouse), so that the user can preferably see the size changed instantly, and preferably afterwards preferably the immediate surrounding text off view is changed (for example the text immediately before and after the visible part of the text), or for example mainly the text after the currently visible text is changed, since the user is most likely to go on reading the text downwards, and the rest of the text is preferably fixed in size only after this, or for example is not fixes at all for display until the user tries to access it or for example each next predicted part is fixed only shortly before the user is about to reach it, since there is no need to calculate in advance the layout of most of the text that is not visible. Another problem is that for example many times the user is trying to type something else in the url line but the browser keeps loading the current page or even over-writes what the user is typing in the url line, which can be very annoying and happens for example especially in MSIE and is also dangerous in terms of security if the user is for example trying to switch to another web page because of security reasons. So preferably this is improved so that preferably as soon as the user starts to type something in the url line of a current web page and/or for example pastes something into it, preferably the browser preferably immediately stops downloading the current web page and/or stops running any scripts from it and preferably waits for the user to finish typing and/or to press Enter, and then preferably moves to the new requested url. Another problem is that if the user for example installs the browser in a new place and copies only the bookmark file to the new installation, when typing a url in the url address line, at the beginning the browser almost does not use any completions based on history. So preferably this is improved so that if insufficient history exists or even when there is, preferably the browser checks also automatically at least in the most recent bookmarks and preferably offers automatically matching urls. Another possible variation is that preferably the browse enables the user also to import and export also history files and/or for example the list of currently open tabs of the last session and/or preferably when copying for example the bookmarks file into a new installation preferably the browser offers the user automatically to copy automatically also for example also the history file and/or the list of open tabs and/or additional parameters or configuration files. Another possible variation is that the user can mark a section (or sections) of the page and then preferably these changes can affect for example only the marked section. Another problem is that unlike the printing of web pages, in which the browser adds the URL usually at the top or at the bottom of the page, when printing for example pdf files from the Internet, the pdf Acrobat reader does not add this info and so the user can later forget where he/she found the document. So preferably this is changed so that for example the pdf viewer preferably automatically adds this info also preferably on each page or at least on the first page of the printing. Another problem is that when saving web files both normal browsers and for example the pdf viewer do not include anywhere the url information. So preferably this is also improved so that preferably the browser and/or pdf viewer and/or other applications automatically add the url info for example at the beginning of the file (for example in the form of a comment or any other form which does not affect the way the file is displayed but can for example be automatically displayed for example by the browser, or for example pdf viewer in case of pdf files, when the file is later reopened locally, or for example it is automatically inserted as a visible text for example on each page or at least on the first page so that it can be viewed automatically when displayed by any editor or viewer). Another possible variation is that preferably any text that the user adds to a pdf file (for example in pdf files that are designed with fillable areas or for example with programs like for example Foxreader 1.3, which allow the user to add text anywhere even on an ordinary pdf file, preferably the user can save the version with the added text, for example as a file that contains both the original pdf data and the added text or for example the application saves the added text automatically separately on a file which preferably point to the original pdf file, thus saving a lot of space. Another possible variation is that the user can for example reduce the size of fonts and/or icons and/or images on the computer&#39;s desktop by a similar command that preferably affects the entire desktop (and/or for example a marked section in it) automatically, preferably by any desired factor, and preferably without having to restart the computer to see the change. Preferably this change is seen instantly, like when increasing or reducing for example the font size in the browser. Another possible variation is that preferably the user can for example use the corners of the box surrounding the text of desktop icons to charge the width and/or height of the text box, so that the text length of the icon name can be made for example wider and in less lines or vice versa and/or change the font size (and/or for example change the width of this font independently of its size) and/or the type of this text (for example for the current icon or for a grouped of marked icons or globally for all the icons on the desktop), instead of the prior art where the use has no control about this. In addition, for example in Windows Vista there is a problem that if the text contains 2 or more words many times the OS automatically hides the end of the text when the user is not on the icon. This can be very annoying since many times for example the user might have more than one version of the same software installed and so the end of the text near the icon (which typically ends with the version number) is the most important for differentiating between them. So this is preferably improved so that the used can choose if to enable this truncation of text or not, and preferably by default it is not truncated (and also there is no need for this truncation, especially if the user can for example change the font size of this text), and if truncation is used then preferably the system automatically finds the differences between similar names and automatically hides only the identical parts (preferably except the beginning) and not the differentiating parts. Another possible variation is that for example if the text of an icon becomes too long preferably the OS can automatically for example reduce its size or for example only make the font thinner without reducing its height, thus saving space with much less burden on the eyes. In addition, if for example increasing the size of fonts and/or of icons on the desktop and/or changing the screen resolution causes a problem that some icons no longer fit on the desktop, preferably this is automatically handled by creating vertical and/or horizontal scroll bars at the edge of the desktop, like in a normal directory window in which there items that don&#39;t fit in the Window. This way the user can for example drag items back in and/or resize the desktop in order to get rid of the scroll bars. Another possible variation is that in this case the system can automatically reduce spaces between icons and/or recommend to the user the maximum size that can be used without problems. In addition, the OS preferably supplies the user with an Undo command (and preferably also a Redo command) for example for changes in the desktop icon sizes and/or for moving icons (and/or for example also for other changes, such as for example removing or adding or changing the position of items that constantly appear near the taskbar, for example at the top or the side of the taskbar, or other changes for example in fields that belong to the taskbar etc.), and this undo is preferably also available for example when moving and/or resizing icons in a directory and/or in other windows. Preferably this undo is incremental, so that the user can preferably roll back for example till the start of the changes (Preferably this is accomplished by automatically saving the positions or the changes between the various configurations for example each time after the movement of one or more icon has been completed or for example after the user closes the window, which is less preferable. This does not take much space since typically simply mainly numerical parameters need to be sufficient). (In the prior art Windows undo is not available for resizing windows and/or changing positions of icons). This is much better than the prior art in which changing the font size and/or the resolution might cause icons to become invisible on the desktop or to crowd over each other. As explained below these undo commands are preferably instantaneous, for example like when pressing ̂Z in the word processor, without having for example to use System Restore, which is much more risky and involves a lengthy reboot. Preferably this undo and/or redo is available also if the user installs new applications (and preferably, like explained in other places in this application, the user can even do a redo that branches into more than one path if the user for example undo&#39;s some icon movement and then changes something and then activates the redo again), and preferably the user can also for example use a command with saves a snapshot of the desktop and can preferably also restore such a snapshot of the desktop preferably instantly (preferably without having to reboot the system—unlike when restoring for example from a system restore point). Preferably this is done in a smart way so that preferably if the user for example restores an earlier state of the desktop that does not include some newly added icons, preferably the system automatically adds the missing icons after restoring the previous state of the desktop. These icons are preferably restored according to the most recent positions in which they were, and/or they are marked in a special way at least when doing the restore so that the user can notice them, and move them to a different position if he/she so desires, and/or for example the user can also scroll back separately to previous positions of these new items. Another possible variation is that preferably the OS saves automatically information about the positions of the icons for each resolution and/or icon size, so that for example if the user tries a new resolution and/or enlarged icons and there is less place for the icons and the user has to move them or they are moved automatically and then changes his/her mind and returns to a higher resolution or smaller icon size, preferably the system can restore automatically the icons to their previous positions or at least asks the user if he/she wants to do this, and then for example newly installed icons are preferably dealt with as explained above. Similarly, preferably the user can also save and later restore for example various resolution settings (such as for example dpi settings, font size, icon size, etc., preferably as a group), and this can preferably be restored for example independently without losing installations of new programs that were done after this and preferably independently from saving the order of icons on the desktop. For this undo and/or Redo preferably the OS (or other software) keeps automatically a rollback log of the changes and/or for example also various snapshots of the icon arrangements, at least once in a while (for example according to time periods and/or amount of change, in order to have additional backup for example in case the cumulative log gets corrupted). This is very important since for example in Windows XP it is very annoying that many things can cause multiple icons to suddenly jump into different positions, such as for example opening some side tools, activating an additional screen, changing the screen resolution, etc. Another possible variation is that preferably the user can for example set as wall papers not just still images but for example also animated gifs or video files (for example avi, mpeg, VBO, and/or other formats). Preferably without needing to install any specific software for this, and then preferably the OS (or some other application) can preferably automatically use this as an animated wallpaper on the desktop (for example a sea view like the popular Azul XP wall paper, except that for example the waves really move and/or for example the palm trees sway a little in the wind or ships move around. Another possible variation is that this preferably moving scenery (or a stationary scenery) contains 3d depth information (for example by being photographed in advance by stereo cameras) and preferably the user can choose for example to move into 3d desktop or back and forth between 2d and 3d, and in the 3d mode preferably the user can for example move icons into various depths of the wallpaper, so that for example icons that are moved to far way (deeper) portions of the scenery (for example an island or mountain in the depth of the scenery) become smaller, and preferably the user can also zoom into various section of the 3d view and thus see them more clearly. Of course this can work even better when stereo view displays become more popular. Another problem is that many or even most of the desktop wallpapers offered for example by Windows Vista contain black or dark areas, which are very inconvenient for placing icons over them since icons placed on such a dark area are either not clearly visible or using brighter text than the background is tiresome to the eyes. So preferably this is improved so that preferably images that are listed as choosable wall papers are preferably automatically converted into brighter images for example by increasing the brightness and/or increasing the gamma factor, and/or for example this is applied automatically only to the black or dark areas in the image, so that preferably the other parts are not affected or less affected. Another possible variation is that if a web page for example contains multiple links to images which show for example just an image, preferably instead of pressing each time a link in order to view just one image and then return to the main article, preferably the user can for example press some key in the browser which automatically expands all the images in the text and thus preferably integrates them into the text as if instead of href links they were “IMG src” commands (or for example at least in a marked section of the page), for example for viewing on the screen and/or for example in a way that automatically affects the printing of the page. Another possible variation is that for example the browser enables the user to dynamically change various elements in the outline of displayed web pages (preferably without needing any change or cooperation from the web server), for example by a drag of the mouse, so that for example the user can move various icons or images to various places on the page and/or for example change their size (for example only of a specific image) and/or change font type and/or arrangement (so that for example a column becomes wider or narrower, etc.) and/or for example add content from other web pages, including for example dynamic content, such as for example streaming video boxes or RSS feeds, and preferably the browser can remember this automatically also the next time the user enters that page. Preferably the browser accomplishes this for example by making automatically a few corrections in the html code accordingly each time after fetching the page to the user&#39;s local computer and/or for example associating some transformation command over the existing html code, and preferably the user can also undo the last change or series of such changes for example with ̂z. Another possible variation is that for example the user can tell the browser to automatically reverse the text in pages with negative text to positive (i.e. cases where the background is more dark than the color of the text fonts, which is much harder on the eye and can be every annoying, and in this case preferably the inversion can be done for example by automatically switching the color between the text and its background or for example by choosing automatically from one or more typical most common or convenient text color-background color pairs). Preferably this automatic correction of inverse text is automatically done by the browser by default (preferably unless the user for example turns this off for a specific site or domain or in general), and preferably by default the chosen correction is by default simply black on white—which is the easiest to read (again, preferably unless the user for example selects another color combination as the favorite for cases where the automatic inversion is required). And preferably this correction is done without damaging or changing any other format and/or features in the page (as explained elsewhere in this application, which is preferably done also if the user manually switches for example from author mode to user mode or vice versa), since for example in the prior art Opera browser, switching between user to author modes usually also creates weird changes in the format. (Of course the browser can very easily find if the text is inversed for example by simply checking if the color numerical value for the background indicates a darker value the color numerical value of the text, or for example the text is preferably judged by the browser to need automatic correction also if the text is too bright beyond a certain threshold, in this case even regardless of the background). This way preferably for example if a site has some special color or pattern in the background which is not too disturbing to the eyes (and even if the text is not in standard color but is still not in inverse), the user preferably still sees it by default as intended by the author, but when the text is in inverse color or reaches some other threshold of unreadable-ity, preferably this is automatically corrected by the browser by default (preferably accompanied by some indication for example on the top corner that the color of the text and/or of the background in this page has been automatically corrected), preferably unless the user explicitly disables this for example for this site or this domain or in general. Another possible variation is that the user can tell the browser for example to automatically adjust the size of too small text, so that for example any text that is below a certain font size is (for example the equivalent of a font size of 10 or 11 or less in a word processor) is preferably automatically increased by the browser to the minimum specified size by the user (for example size 13), and preferably in this case the text is increased automatically without automatically increasing also the near images, but preferably for example adjacent headlines are preferably also automatically increased by the same ratio in order to preserve the proportions. Another possible variation is that by default preferably the font size is automatically changed by the browser for example according to the user&#39;s behavior in other similar pages, so that for example sizes of web pages at least in the same domain are preferably automatically increased when needed to fit the size which the user himself/herself chose by enlarging or reducing previously other pages. When automatically increasing the size of fonts in web pages preferably the size is not increased to a point where a horizontal lever would be required to move the page right or left, or for example the size can be automatically increased even to a size which requires such a lever—at least for example if the font in so small that only by such increase a minimal reasonable for size can be achieved. In addition, preferably the browser can also remember automatically the desired default size for example according to repeated user actions in a similar situation and/or for example when the user explicitly enters a command which requests the browser to remember and repeat this for the similar situation, so that for example each time the user opens a video for playing in a new tab for example in youtube, preferably the browser automatically increases the size of the page into the typical size which the user tends to choose each time when opening for example video in youtube into a new tab, or for example activates by default automatically the full-screen mode for this if this is what the user usually does or for example did the last N times. Another possible variation is that the user can preferably for example tell the browser to automatically fit for example the size of web pages to the screen so that for example web pages that do not take advantage of the full available space are preferably automatically increased (in this case preferably the text together with the images), and/or for example if the font is already big enough (as determined for example by being of a certain threshold size or larger, which can preferably also be changed by the user) for example paragraphs can be automatically reformatted to take better advantage of the wider space, and/or for example web pages that contain for example a horizontal scroll bar (for example because of containing a table) can preferably automatically be reduced in size and/or for example at least the browser automatically makes the fonts for example in the relevant table areas preferably automatically at least thinner. Preferably the user can specify independently if he/she wants pages to be increased in size automatically and if he/she wants pages with a horizontal scroll bar reduced automatically. Another possible variations is that preferably the OS or the firewall or security system or some other application preferably also prevents programs or drivers from changing or switching for example between icons for example on the desktop or on the quick launch line without user permission, since if icons are switched for example by a virus or worm or trojan or other malicious application (even without changing the linking of file types to applications that run when the user clicks on them) then the user can be misled to activate the wrong program while intending to activate another program (and if the user has for example allowed this by mistake, preferably the above described undo can also fix that, preferably without having to launch for example system restore). Another possible variation is that the system or for example the security system can for example display automatically for example upon request a list of which applications are the default opener currently associated with each type of file, and preferably the user can also edit this table in order to correct or change associations. Preferably this is not just a table of which file type is associated with what application but the table preferably contains also for example near each file type also a list of all the applications that can open it, so that if the user wants to change the default opener he/she can preferably choose from any of the other listed application for example by just ticking a box near it. Another possible variation is that the user can define these associations also in a way that is dependent on the location and/or the context, so that for example the default player for flv files is zoom player, but if an flv file is for example clicked on in the browser then preferably it is opened by another application, or for example the default opener for doc files is for example Word 2007 but if they are in a certain directory then the default opener is for example Word 2000. Another possible variation is that the user can preferably also lock one or more such file types, for example by clicking on a special icon in the line that represents that file type in the table, so that preferably other applications cannot become the default openers for that type until the user explicitly removes the lock, or for example if the file type is locked then when an application tries to become associated with it as its default opener preferably for example the OS or the security system request from the user explicit permission for this, or for example any such change for any file type requires explicit permission by the user without the user having to explicitly lock it first, as explained in no other applications by the present inventor that deal with computer security. Another possible variation is that the table can also sort the file types for example by higher categories (such as for example document files, sound files, video files, images, etc) and/or just alphabetically, and/or the user can preferably also associate for example at the level of the higher category, such as for example marking that video files will be handled by default for example by Zoom player. Another possible variation is that the user can also ask for example the OS to sort the table for example so that the entries are the applications and the entry for each application shows to which file type it is associated. Another possible variation is that for example when the user hovers with the mouse over a data file (or for example when he/she clicks on it with the right mouse button) preferably the OS automatically shows which application will be activated if the user clicks on the file. Another possible variation is that the OS for example enables the user to easily edit the options that are shown when the send-to menu option is chosen, such as for example removing or adding items to it. Another problem in the prior art (for example in Windows XP) is that reducing the resolution and/or increasing the system font size can cause the window that asks if to keep the new resolution to appear outside of the desktop (i.e. become invisible) and/or cause the text in various system message windows to appear truncated. This is preferably automatically prevented, and for this preferably the system automatically calculates the new size and ratios and thus makes sure that all the message windows appear in a visible area and that the text size in them fits the message window, and if not then preferably the message window&#39;s size is automatically adjusted as needed and/or the font size in the message window is automatically reduced as needed and/or for example scroll bars are added to it as needed. Although Microsoft recently announced that the new Longhorn version of Windows will contain smooth scaling (a feature which exists already in Macintosh OS X), there is no indication that the above described features regarding the desktop will be included, and the smooth scaling is apparently relevant mainly to flicker free animation and to DPI scaling or window scaling instead of only window resizing, i.e. the ability to automatically change the size of text and images through the graphics card, so the some of the above described features will be easier to implement (but without the above features, changing for example the scaling of the desktop can lead to exactly the problems that some of the above features are intended to solve). Also, preferably the ability so increase or decrease for example the size of the text and/or of the images and/or icons for example in web pages or in other windows as described above is preferably independent of the size of the window, since scaling the size of the text and images automatically by the window size is more relevant for special animation effects involving the windows (such as for example juggling or rotating windows around the screen), but when the user wants to work on the window typically he/she would want to be able to choose the most desirable size of fonts and/or images regardless of the size of the window (This means that for these purposes the resizing is preferably done by reformatting the page, like in the above described Netscape feature, and not by some purely graphic effect performed by the graphics card). Another possible variation is that for example if the user changes the screen resolution, the fonts and/or icons on the desktop and/or in other places or applications (which means of course also for example menus, the taskbar, and/or anything else in the user interface, preferably the entire user interface) by default remain more or less the same size (unless for example the user explicitly requests to change them, which can preferably be done independently of any change in screen resolution), preferably by using for example the smooth scaling to automatically correct for the changes caused by the changed resolution, so that if the user increases the resolution, the fonts and/or icons and/or images (and/or anything else in the user interface) can be automatically increased in size to compensate for this and if the user decreases the resolution the fonts and/or icons and/or images can be automatically reduced in size to compensate for this. So if the user for example switches from a resolution of 1024×768 to a resolution of 1280×1024, the fonts and/or icons are preferably automatically increased in size by the appropriate factor (in this example preferably they are increased in width by 25% and increased by height by 33%, and/or the aspect ratio is maintained by default so that the width and height are for example both increased by the higher value or by the lower value or for example by some average value. This means that preferably for example even the mouse&#39;s movements are automatically compensated accordingly, so that for example if the resolution for example increases and so the number of pixels the mouse has to travel is larger, preferably the speed of the mouse&#39;s movement remains the same, so that the same distance of mouse travel on the desk is still needed for traveling for example from one edge of the screen to the other edge (preferably unless the user changes this explicitly, which is preferably again independent of the resolution). Even if for example for any reason the OS still needs for example a reboot in order to apply these changes throughout the system, then preferably while the user is changing for example the resolution for example to a higher resolution (which according to the above should preferably actually mean only that the text and images become sharper and/or with more derail, but the user interface does not become automatically smaller) or the user is changing the size of the user interface independently of the resolution (which means that for example preferably everything in the user interface or at least the main elements in the user interface grow or shrink (for example except some automatic adjustments, such as the taskbar for example always automatically filling the full width of the screen, etc.), preferably the OS automatically displays to the user these changes in real time as a preview, so that preferably the user can for example move one lever for example left or right and see preferably a smoothly changing preview of the effects of changing the resolution as he/she is moving the lever, and preferably similarly moving for example a separate lever which changes the user interface size is preferably accompanied by a preferably smooth preview of the changed size of the user interface (for example the size of the icons on the desktop and the area occupied by them, the size of the taskbar, menus, fonts, etc). This preview is preferably done at least by emulation, so that the OS preferably displays it at least while the user is for example moving the lever. Another problem is that for example icons that have not been designed for higher resolution might appear a little zigzaggy at the higher resolution, So this is preferably solved so that if for example the new resolution is for example close to twice the original resolution then preferably each pixel is automatically duplicated, and if the ratio is not a direct multiple, then preferably for example the missing pixels are automatically interpolated heuristically, for example by using different colors and/or brightness and/or contrast and/or saturation for the added pixels, for example in a way similar to the way that the resolution of fonts is increased in the Cleartype method. Another possible variation is to use for example similar automatic interpolation when increasing images in web pages-especially for example in cases of diagonal lines and/or graphic bitmap images of fonts (since in this type of images the zigzags upon enlarging are much more conspicuous than for example when enlarging photos), so preferably diagonal lines and/or graphic images of fonts and/or the zigzags themselves (for example compared to the situation before the enlargement) are preferably automatically detected (for example by any known OCR methods) and are preferably automatically corrected as explained above (for example all zigzags or more or less the same granular size are preferably automatically identified as resulting from the enlargement and then automatically corrected). Another possible variation is that for example such graphic letters and/or images are preferably automatically converted by the browser for example to preferably high-resolution vectors before the enlarging, for example based on various heuristics. Another possible variation is that preferably for example the gif or jpeg and/or other image formats are improve to contain in advance data for multiple resolutions, so that for example a gif or jpeg image can contain at the same time more than one image, each optimized in advance for example for one of the common resolutions (for example in a way similar to the way that an animated gif contains a set of images), so that preferably each such sub-layer of version in the image preferably contains a tag that indicates to which resolution it is best fit (this can be most useful for example for representative icons that need to scale well, such as for example the ‘Google’ logo in the Google search page), so that when the resolution is changed the browser can automatically display the optimized version of the image for that resolution, or for example the browser transfers the user&#39;s current resolution to the server and the server can for example automatically transfer for each image only the relevant resolution if the image contains different version optimized for different resolutions. Another possible variation is that the user can for example increase or reduce the size of the icons and/or of their text by zooming in or out on the desktop itself for example by pressing control and moving the mouse wheel, in a way similar to increasing or reducing for example the text and images in web pages (so that preferably for example if there is not sufficient room for example the gaps between the icons are automatically reduced or for example, as explained elsewhere is this application, a scroll bar is added when needed for example sideways and/or up-down so that the user can reach also icons which become out of the screen and can move them back manually). In addition, preferably the user can also mark one or more specific icons on the desktop so that the enlargement or reduction affects only them, instead of all the desktop icons. Another possible variation is that this can affect also for example the size of the background, but that is of course less preferable since normally it would mean unnecessary change in the background, so preferably if the user wants to zoom-in or out on the background this is preferably done by separate controls. If for example the default is the average, this has the advantage that by default the minimum change in icon shapes will be perceived. However since, as explained above, the desktop preferably remains the same size, preferably by default at least the distances between the icons are corrected in each direction by its appropriate ratio of change, i.e. in the above example preferably 25% in width and 33% in height, with or without similar change in the aspect ratio of the icon. Preferably the user can choose among these options). Of course various combinations of the above and other variations can also be used. Another possible variation is that if the user for example wants to copy more than one application at the same time for example from the “all programs” pop-up list which is activated through the Start button, for example to the desktop, then preferably he/she can mark more than one item at a time (for example by dragging the mouse to darken a group of them and/or for example by marking a group with CTRL or Shift pressed) and/or the list remains open even after dragging an item (unlike the prior art, where immediately after dragging the first item to the desktop the list disappears and has to be opened again from the Start button, unlike for example a window created through Explore). Another possible variation is that preferably the user can drag a shortcut also for example from normal open applications on the taskbar (for example by dragging the square on the taskbar that represents the application) and/or for example by dragging something for example from the top and/or other parts of an open window (for example by clicking on the right mouse button, for example onto the desktop), and/or for example from the file name as it appears in a DOS or cmd window (so for example after opening once the task manager preferably the user can drag it from its square on the taskbar to become an icon on the desktop, so that next time it can also be activated from this icon). If for example the desktop is not visible due to full open windows, preferably the user can for example hover the dragged item near or over for example the “show desktop” icon and then preferably the desktop shows and lets the user take the item to wherever he/she wants and preferably after dropping the item there the windows preferably automatically return to the state they were in before the dragging of the item. Another possible variation is that the user can for example drag for example onto the desktop also menu items within the user interface (for example within the options in the menus of the taskbar or within the menus that show when the user clicks on the Start button, so that the dragged menu option becomes a separate icon on the desktop that can then be activated directly from the desktop, and in this case preferably the icon becomes automatically for example with the shape and text of the menu option that was dragged there and of course the user can preferably change the icon and/or the text to whatever he/se wants. So for example the user can preferably drag to the desktop this way for example the Screen Saver (from the Display Properties menu), the “Create a Restore Point” (From MSCONFIG-&gt;Launch System Restore menu), Another possible variation is that for exampling when going over programs or program folders within the Start menu (for example after choosing “All Programs”) preferably the user can also mark multiple programs and drag them together to the desktop (for example when reaching the Office folder in the “All Programs” menu), Device Manager, Task manager, etc. Another possible variation is that for example in Windows Vista the internal search of the Start menu and/or for example the general instant desktop search (for example the Google desktop search) can preferably also search for example within menu options of at least the OS&#39;s user interface (for example by automatically following the available menu options after the user goes through them at least one time or by indexing it directly for example from one or more elements in the user interface files), so that if the user for example searches for the words “create restore point” or “restore point” the system can preferably automatically display the menu option of creating a restore point eventhough it is an option within the system restore, and for example if the user types “device manager” preferably that menu option is automatically shown. Another possible variation is that preferably various applications or at least one or more of the more complex ones—such as for example Word, preferably enable the user for example also to search for various functions (i.e. available commands) in a search menu instead of having to find them in various pull-down menus or in the new ribbon of office 12 (later renamed Office 2007), so that for example preferably the top of the word processor window contains a search window for entering a word or words which the user searches for in the user interface, so that for example if the user types the word footnotes preferably an automatic menu shows up with commands related to footnotes (for example in a pull-down menu or for example in the ribbon) or for example if the user types the word translate or dictionary for example the menu items related to the dictionary automatically become visible and/or for example the dictionary window is automatically opened, or for example typing the word ‘paragraph’ in the menu search box will display a menu of all the commands that are related to paragraphs or for example have the word paragraph as part of the menu option, and/or for example typing the search word can automatically select the most appropriate option within the ribbon (or other menu system) as if the user reached it in the normal way, or for example typing the word “ruler” will automatically enable the user to add the normal ruler on the top of the page with the slide-able triangles which users are used to in previous versions of word but does not show by default in Word 2007. Preferably when the menu is shown the searched-for option is also pre-selected, so that for example simply hitting the Enter key can choose the option (however the user of course preferably can also click on it with the mouse). Another possible variation is that for example any typing by the user on the area of the top menus or on the ribbon achieves this result without having to type directly within the search box or even without a search box. Preferably the above search works instantly like the Google desktop search so that the response is instantaneous as the user types characters, without having to press Enter at the end. In addition, preferably when clicking again on the internal search window (after doing something else) or for example on the normal desktop search window, or for example on the search window within the start menu, or for example on the search box for finding bookmarks in the browser, preferably before the user types the first character preferably the search engine or application preferably instantly displays as default the results of the last search that was conducted, and only then it is preferably automatically preferably instantly changed or removed if the user starts typing a character or at least a character that is incompatible with the previous string, instead of for example using the right or left arrows or home or end to make changes in the existing string. Another possible variation is that when the user gets the results from this search in the bookmarks preferably he/she can jump from the search line to any desired result also by using the arrow keys, like in the results of the Google desktop search, instead of being able only to move the mouse in order to click on a result (this is more efficient, since after the user types the search string, his/her fingers are still on the keyboard, so moving with the arrows at that stage is faster than having to move the hand away to the mouse and then move with the mouse). Another possible variation is that for example after the user finds one or more results in the bookmark search the user can for example mark one or more results (or for example if the user clicks on it to open), preferably if the user then goes back to the search string and removes characters, preferably the showed bookmark preferably by default remains in focus and is preferably automatically shifted each time in position so that it remains at the center of the list as more bookmarks appear, so that if for example the user then removes all the characters from the search string then preferably the user sees the all the bookmark links around the marked link (or for example the last clicked link)(with preferably as many links as fit in the visible windows of the bookmarks list), which can be very useful if the user for example find some bookmark that dealt with some subject and then wants to browse all the bookmarks which were created at the same time and so are typically next to it in the bookmarks list. Another possible variation is that if the user decides to enter the “Help” file, the commands that he/she finds there are also clickable and preferably when clicked upon bring the user directly to the correct menu option or for example ribbon configuration as it would look if the user had reached it the normal way through the menus or through the tab handles of the ribbon. Another possible variation is that preferably the word processor (or other application) can use also for example the descriptions in the help file related to each command for adding them automatically to the above described searchable command/menu options index, so that the user can find a command or menu option also if he/she does not remember its name but only for example something which describes it. In addition, preferably the internal command search uses also the thesaurus, since the user mighty for example use some different wording than the actual name or description of the searched command. Another possible variation is that for example the instant desktop search (such as for example the Google desktop search) can automatically for example follow the menu items for example in the ribbon or pull down menus (for example by letting the user define the relevant screen area or more preferably by following though heuristics the relevant typically squared areas on top of the screen) and generate for example automatically an index for finding these commands, but this is much less preferable since it is much more reliable and powerful to build this from inside the application. Another problem for example with Word 2007 is that it forces the users to work only with the new interface without an ability to go back to the old interface, which means that for some things which the user knows instantly how to access on previous versions (for example Word 2000 or Word 2003 or for example other previous Office applications) the user might have to spend a long time to learn how to reach them in the new ribbon interface, which can be annoying and frustrating even with the above internal commands/menu search variation (since the user still has to type the search string instead of clicking directly on something which he could do instantly in the old interface and the user still has to remember the new way to reach it even if the search result also includes automatically configuring the ribbon to the same state it would be if the user choose it through the appropriate tab handle/or submenu option, as explained above). So preferably another improvement is that preferably, at least as an option, the user can choose for example to have the old menu available at the top of the page in addition to the ribbon (and/or for example to temporarily hide the ribbon in this case, to save even more space), which is very easy since at the top above the ribbon there is sufficient room to add the normal classic menu of File, Edit, View, etc, with the normal pull-down menus (which are preferably updated to include also for example the new features of Word 2007). Another possible variation is that if the user for example prefers to use the above menus without hiding the ribbon, preferably for example when choosing anything on the top menus or with pull-down menus, preferably the ribbon automatically, preferably instantly, changes also to the appropriate configuration, so that the user can also instantly see how to reach the same command through the ribbon tab-handles and sub-menus. For this preferably the Word processor has, preferably for example in the same index used for the above described internal command search feature, also for example a link for each entry to the menu steps needed in order to reach it for example through the ribbon, so that after reaching the command (for example either through the old classic menu system or through the instant search) the system can preferably instantly show also the correct ribbon/menu configuration for reaching it. Of course, the above described internal command search and/or for example the instant desktop search or for example the search within the start menu can preferably also be activated by voice commands, and preferably the system knows to which type of search the voice command refers for example by looking at where the mouse is currently hovering, or by the user adding for example a selector keyword at the beginning of the voice command. Preferably in case of voice commands or when typing the search string in the internal command search preferably the user does not have to go through the normal menus but can preferably access any menu option directly, but if there are more than one likely result then preferably all the relevant results are automatically shown for example listed one below the other, preferably with some context identification so that the user can understand what each command is, and the user can preferably move with the errors and choose any command, in a way similar to choosing applications for example in the results of the Google desktop search. (However as explained above, preferably in addition to this list, the most likely top result or the result chosen by the user is preferably also indicated automatically in the ribbon or menu system configuration so that the user can also see how to reach it the normal way). Another possible variation is that preferably the user can for example copy any item from the ribbon or preferably from any other menu option for example to the area above the ribbon so that for example the commands which the user uses most frequently become available for instant direct clicking, and/or for example the word processor can do it automatically for the user by identifying the commands which he/she most frequently uses in general or for example in the last N minutes or the last N commands (where N is any a reasonable periods or a reasonable number of commands). If for example the word processor also enables tabs as an alternative to opening additional windows, then preferably the tabs handled of these tabs are above the tab handles of the ribbon. But preferably below any to-level menu if for example the user request to enable also the classic to menus, as explained above. Another possible variation is that preferably at least some of the pull-down menus for example in Word 2007 or most or all of them are preferably made at least partially transparent so that the user can also see at lest in general the text below them. This is very important for example when various styles which effect the whole page are shown, such as for example various options of placement of pictures, because hiding part of the page makes it harder to have a preview of the results. Another possible variation is that for example the various choices within the pull-down menu (such as for example the various patterns or options that the user can choose form, such as for example the various latter shapes in the WordArt of Word 2007) are preferably semi-transparent or even non-transparent, but the window that surrounds them in the pull-down menu is preferably fully transparent (for example whenever this pull-down menu is shown or at least when the user hovers with the mouse on one of the choices within it), except for example some preferably thin border, so that at least the user can see the text between the options that can be chosen in the pull-down menu, and/or for example the other possible choices become transparent or semi transparent when the user hovers with the mouse over one of the choices. Similarly for example in Windows Vista when choosing a desktop background there is an even bigger problem that each time after choosing a background most of the background is hidden by the window of the choosing menu, so the user has to minimize this window or click on the “Show desktop” icon in order to see the background in real size, and then the user has to open again the choice window if he/she wants to test additional backgrounds. So preferably this is improved so that preferably merely hovering on the small image of a background with the mouse preferably immediately shows a preferably full-size preview of it (preferably by showing the full-size desktop with the selected background and the icons on it), and/or the window that lets the user chose is preferably made transparent (except for example for some preferably thin borders) for example at least when the mouse is hovering on one of the choices or when the mouse is hovering one of the exposed areas of the desktop or even all the time that this choice window is open, so that preferably only the small backgrounds are preferably non-transparent. Another possible variation is that preferably when the user hovers with the mouse over a visible part of the desktop preferably even the small background images preferably become semi-transparent or for example fully transparent or with just some frame border, and when the user moves the mouse near there area preferably all of them automatically reappear, and so preferably mere movement of the mouse without having to even click on any background can preferably instantly show a preferably full-size preview of the background, preferably with all the icons on it as if it has been chosen. Another possible variation is that (for example when the user is in the menu that allows selecting desktop backgrounds or for example in a program that displays images) the user can preferably for example simply press some control key and use for example the mouse wheel at the same time, and this way preferably the user can move quickly preferably over a large set of possible wallpapers, which preferably show up preferably instantly preferably in full size and with the icons in place, so that the user can preferably instantly see how each background will look in practice, which is much faster and more efficient than the prior art method of needing multiple clicks just to test a single wallpaper. Another problem with choosing a background is that although there is typically a nice selection of beautiful backgrounds (usually outdoors scenery), most of these backgrounds are not really suitable for use as desktop backgrounds because they have too many dark areas or otherwise have for example too many different brightness levels. The problem apparently stems from the fact that the human brain is accustomed from evolution to perceive black as foreground and white as background, so any situation where the icon or text is bright on a dark background can be very tiring to the brain, similar to the problem of reading white text on a black background. So this is preferably improved so that images that are added to the menu of available desktop background are preferably automatically converted by the OS preferably at the time of adding them to the menu (and this converted copy is preferably automatically saved in the relevant directory of background choices), so that preferably for example their general brightness and/or gamma values are automatically increased or for example only the dark areas are automatically identified and increased for example in brightness and/or gamma level (for example by going over all the pixels and picking automatically any pixel with a darkness level beyond a certain threshold and preferably converting such pixels to values that represent for example higher brightness and/or higher gamma levels). This means that the pictures may become somewhat distorted, but the resulting desktop background when covered with icons becomes much less tiring to the brain and more pleasant to the eye. Another possible variation is that the user can for example point with the mouse to one or more areas that annoy him/her when icons are placed on them and preferably the system then automatically finds the borders of such areas and preferably automatically converts them for example as explained above. (Preferably areas that are considered as dark are not only for example dark or blackish areas but preferably also for example strong red or orange, which can have a similar effect). Similarly, for example too white (or otherwise too bright) areas on the wallpaper can also be problematic, since in this case white part of the text of the icons become less visible, and also the whiter sections might dazzle the eyes compared to the other areas and thus create eye strain, so another possible variation is that in such areas for example the gamma is automatically lowered and/or for example these areas are automatically converted and saved as less bright, and/or for example in such areas the ratio between the white and the black outlines of the text near icons that are on such areas is automatically changed so that for example the font of the texts which accompanies the icons becomes for example automatically with a wider black outline and/or for example the white part of the outline preferably becomes automatically of a darker color and/or for example is removed altogether so that the text there becomes only dark (this effect of changing the appearance of the text as long as the icon is in such an area is preferably only a display effect, so that preferably it is not saved in the file of the icon. Another possible variation is that for example when choosing a background the user can preferably for example move one or more levers which preferably automatically become available (for example in the background-choosing menu or for example in one of the normal menus of customizing the desktop), for example for changing the gamma and/or brightness and/or other parameters, and then the changed image is preferably saved as an additional choose-able background, preferably with an indication for example near its name that it was customized by the user, so that the user can preferably easily find it again if he/she for example experiments with additional backgrounds and then decides for example to return to it. Another problem is that the ribbon increases the control area at the top of the page at the expense of the visible area of the document, which can be inconvenient for example to users of Word 2000 or 2003 who are used to and prefer to have a bigger visible text window. So preferably this is improved for example by enabling the user for example to drag upwards the border at the bottom of the ribbon (and/or for example borders above the ribbon, but preferably dragging the bottom of the ribbon is sufficient to affect also items above the ribbon), which preferably causes the height of the ribbon and/or of the parts that are above it to shrink in height automatically, preferably proportionally but preferably in a smart manner, so that for example the ribbon tab handles can preferably become shorter by reducing unnecessary spaces below and above the tab handle names preferably without the letters themselves shrinking in height, and/or for example similarly the top header line which contains the file name can preferably shrink in height similarly preferably without the letters themselves shrinking in height, and/or for example similar principles can be used for shrinking the height of the ribbon itself (which means for example shrinking the height of the graphical icons of the ribbon and/or of the spaces above and/or below them), and/or this automatic shrinking is for example done by default by the word processor (and/or the user can pull the bottom border of the ribbon and/or other borders for example above it down if so desired, in order to increase the height of the ribbon). In word 2007 beta 2 TR (after the above was already included in earlier priorities of this application) Microsoft added the option to minimize the ribbon, but this minimization is based on removing all the info except the ribbon tab handles (which is less functional than the above solution), and whenever the user clicks on one of the tabs the full ribbon shows again. Another problem with this new addition is that when the ribbon expands again it can cover the top lines of the text even if the user was for example in the middle of editing them (which can be very annoying and confusing), and it can also cover the right elevator so that the user can become very confused. So preferably this is improved so that if this feature is used, preferably when the ribbon expands the text is preferably automatically scrolled up or down as needed so that the section which the user was currently editing will still be visible, and preferably the range of the elevator is preferably automatically adjusted to move only in the new visible area. Another possible variation is that preferably the horizontal size of the ribbon is decreased so that preferably both in the minimized state and in the expanded state of the ribbon the right edge of the ribbon preferably reaches a few millimeters less so that preferably the vertical elevator is preferably fully visible even when it is at the area of the expanded ribbon. In addition, as explained elsewhere in this application, preferably merely hovering with the mouse on one of the tabs of the ribbon preferably automatically displays the options of that tab, so preferably if the ribbon is minimized in Microsoft&#39;s way then preferably hovering over one of the tabs also automatically expands the ribbon without the user having to click on it. However, another problem with using hover over items of the ribbon to have an affect like clicking is that in Word 2007 currently if the user hovers on at item a short explanation is displayed after 2 seconds. So preferably this is solved so that (as explained elsewhere in this application) the hover preferably instantly has the same effect as clicking in the tab handle or item, but if an explanation is needed (which is preferably only in a small percent of cases where the menu that is opened after hovering or clicking is still not sufficiently clear without further explanation), then preferably the explanation appears automatically as part of the menu which opens (for example at the top or side of it or at the bottom, when needed). Another possible variation is that for example clicking on various links in the relevant help file can also automatically display the relevant menus for example in the word processor and make the user jump to that option. Another problem is that for example the Opera browser enables the user to mark a text (or for example use ̂A to mark the entire web page) and then right-click on it with the mouse and choose “speak” to hear the text through synthesized voice. However this is still not useful enough for example for people who are visually impaired because they might have a problem with choosing the speak option or clicking on the text. So preferably this is improved so that this works preferably in combination with voice commands, and for example when “speaking” the text preferably the browser states when it is a link and lest the user for example to request going into the currently spoken or the last mentioned link or to request for example “Go to previous link” or “Go to previous kinks” and then preferably the browser for example reads only the text of the previous links and asks the user through voice communication which one of them to go to. Another problem is that both the Microsoft desktop search and the Google desktop search ignore for example file extensions when the user is searching for something. So preferably this is improved so that if the user for example types also the file extension for example after a dot or separated from a string within the file name for example by a space or spaces or by wildcards (for example the user types in the search box “*epiph*.avi” or “epiph*avi” or “epiph avi”), preferably files that contain the word in their name and also contain the desired extension are displayed in the results before files that don&#39;t have that extension, or for example files without that extension are not displayed, but the first variation is better because the user might make a mistake in the extension, so preferably he/she can see it the following results. Preferably for example such wild cards work at least the way they would work for example if typed for example with a ‘dir’ command for example in a cmd window. Also, preferably files that contain the desired string closer to the beginning of the file name are preferably displayed before files that contain it at the middle or end of the name, but preferably, as explained above, files with the desired extension preferably appear earlier. (Preferably the user can this way for example also look for all the video files of one or more types, etc.). Another possible variation is that for example the indexed desktop search can monitor which application or applications the user is currently using and take this into account as context for the search, so that for example if the user has just opened for example the PowerDVD program (especially for example if the user has an open browse window in that application) and then goes to the indexed desktop search preferably the desktop search shows first results that are related to video files even if the user did not indicate it, since it is most likely that the user will be looking for such files in this case. Another possible variation is that for example the application itself (for example PowerDVD) can preferably interface with the instant desktop search for example through a standard common interface and for example look automatically for all the files of certain types and thus add them for example automatically to an automatically generated play list or for example open an internal search box which searches for example only for video files and preferably gives instant results as the user types the letters, but preferably gets its results from the indexes generated by the desktop search, preferably by communicating directly with the desktop search application. Another possible variation is that preferably the user can also use for example regular expressions for example in the search string in the desktop search (such as for example Google desktop search or the similar instant search offered by Windows Vista) and/or for example in the dir command for example in a CMD or DOS window and/or for example in the dialogue box for example for opening files, which means that for example the search string can include ‘or’ expressions and/or for example more complex wild card patterns. Similarly preferably including for example “/” signs before and/or after and/or within the string preferably indicate searching for directories so that preferably the desktop search shows at higher positions results which fit the desired path. Another possible variation is that preferably if the desktop search is for example floating, like for example one of the common modes of the Google desktop search, preferably the floating desktop search bar is at least semi-transparent so that the user can see also the text behind it, since for example normally it might be most convenient to put it for example on the top of the screen but sometimes this will cause obstruction for example of part of the title of for example a web page or a word processing file (which typically appear in the top header of the window), and/or for example when the floating desktop search bar hides text, preferably it can be moved automatically for example down preferably one line and/or sideways (for example by the OS or by the security application, which are preferably the only processes that are allowed to see the final overlay positions of texts on the screen from multiple windows), and so preferably when the desktop search floating bar hides text for example the OS preferably automatically finds the nearest sufficiently empty space and moves the floating bar there. Another possible variation is that preferably the user can preferably tell the desktop search (for example the one run by the OS for example in Vista or for example run by a third party such as for example Google desktop search) for example to move its index for example to another drive or another partition, and in this case preferably the desktop search application automatically copies the index to the new destination and erases it from the original destination. This is important for example if the partition which contains the windows installation (and also by default the index of the desktop search) becomes with to little free space. Another possible variation is that if for example the free space on the partition becomes too small, the desktop search (which can be for example Google desktop search or for example Vista&#39;s inherent indexed search) can preferably for example automatically move at least part of the index to another partition (and preferably it chooses automatically for example the partition with the largest empty space for this, and preferably it marks automatically in the new directory to which partition and/or OS the index belongs and/or preferably it informs the user about it and/or lets the user confirm the suggested partition or partitions and/or choose one or more other partitions for this). Another possible variation is that preferably the user can tell for example a newly installed OS to use another index which has already been created in another OS—for example by indicating the drive letter, and/or for example when installing in the new OS, the desktop search application or for example the OS itself (especially for example if this feature is integrated in the OS itself, such as for example the indexed search in Vista) preferably finds automatically if such an index exists already in one or more other partitions that belong to another OS and can preferably automatically suggest to the user to use it, and if there is such an index in more than one other installed OS then this is preferably done after checking which one of them is the most updated (for example by checking their last update date and/or for example their size and/or for example the number of files and/or directories indexed, and this data is preferably available already in a summary form in each index), thus avoiding unnecessary re-indexing if the index was already created by another OS (thus saving both time, which can take for example even a few days if the disks are very large, and disk space), and so the new OS preferably continues to update the same index while the new OS is run, so that when the user returns to the previous OS the index is preferably already updated for example with the new files and directories that the user added while working in the new OS. Another possible variation is that if for example there are different versions of the desktop index installed for example in different OSs, preferably this is also taken into account, so that for example if the chosen index was updated by a later version of the desktop search software (which is preferably determined for example by an indication of the software version which the software preferably automatically stamps in the database), then preferably the user is warned that he/she must first update the desktop index software version before choosing that index. In addition, preferably after choosing the most updated version of the index preferably the user can also request for example to delete older or partial indexes which belong to other OSs, and then preferably if the user returns another OS in which the less updated index was deleted, then preferably the user is again prompted automatically to use now the best index that was chosen in the other partition. Another possible variation is that for example after the most updated index is found preferably the user can also request for example the OS or the desktop search software for example to copy this index into the new OS instead of starting updating in for example in the partition that belongs to another OS, in which case still a lot of indexing time is saved and the two indexes can than for example start to be updated separately or even diverge as needed, even though this is of course more wasteful in disk space. However, if there are for example various security considerations, such as for example different access rights to different OSs, for example to various files and/or directories and/or partitions and/or even entire devices (for example an entire hard disk) the preferably for example the security system or the OS or the desktop search software preferably automatically allows each OS access only to the parts of the index that relate to it. If for example copy on write is used for example when installing the new OS and/or is implemented in other ways afterwards then preferably the most updated index can simply be available automatically for example to the new OS based on copy on write, and if the user prefers for example that each OS will continue to update the indexes separately or for example if it is required due to security considerations (for example different files and/or directories and/or partitions or other devices that only one or more of the OSs can access but not one or more other OSs), then preferably the divergent updates continue from the original available and allowed part of the index, and preferably similarly preferably when making the original copy of the index available, preferably appropriate security filters are applied so that the part of the index that deals with files or partitions or devoices directories that should be available to the new OS are preferably automatically hidden from the view of the index that the new OS gets. Similarly, for example if more than one OS is running at the same time (for example in a system with a hypervisor below the OSs), at least if the same desktop search application is working in more than one OS, preferably for example the desktop search application of each OSs for example automatically finds the most updated version of the index and suggests it to the user, and preferably the user is also preferably asked to chose in which OS to continue running the Index, so that for example the OS to which the most updated index belongs and/or for example the OS in which the most updated version of the desktop index software is installed is preferably the only one that continues updating it for example even when the user temporarily witches to another OS, however, as explained above, preferably the most updated index is chosen and if needed then preferably for example the OS or the desktop index software or for example an element running in the hypervisor level preferably prompts the user to update its version for example if the chosen index was last updated by a later version of the software, or for example each time the current OS in which the user is working is preferably the one that continues to update the index, but preferably no more than one OS is active in updating the index at the same time. A similar problem is that for example in Windows XP and even for example in vista RC1 if the partition where the OS is installed becomes with too small free space the OS automatically deletes the older restore points or even all of the restore points without even warning to the user. So preferably this is improved so that when the partition where the OS is installed becomes with too small free space preferably the OS automatically transfers for example at least some of the restore points automatically to one or more other partitions (Preferably the OS chooses for example automatically the partition with the largest free space and/or for example informs the user about it and asks the user to accept the suggested partition or mark one or more other partitions where restore points can be saved, and preferably the OS creates automatically for the restore points in the other partition for example a directory which contains for example in its name and/or for example in one or more files within it information about the partition of the installed OS which these restore points belong and/or other identifiers about this OS). In addition, preferably when showing the user the list of available restore points, preferably the OS indicates near each restore point the drive letter and/or the full path where it is stored. In addition, preferably when showing this list the OS also enables the user for example to copy one or more restore points for example to any other drive and/or directory which the user desires, thus creating an additional backup which the user can always access for example if the OS later deletes that restore point from the OS&#39;s automatically managed set of restore points. Another possible variation is that the user can for example mark one or more restore points as protected, so that as long as they are marks they can never be deleted automatically for example until the user unmarks them. Another possible variation is that similarly preferably the OS preferably automatically moves the swap file or one or more parts of it and/or for example other types of system files to another partition if the partition on which the OS is installed (or on which the swap file is now or for example other large system files are now) becomes with too small free space (and preferably chooses automatically for example the partition with the largest free space on it), or for example notifies the user about the problem and asks the user to agree to this and/or choose the partition. Another possible variation is that similarly preferably the OS preferably automatically starts installing by default new programs into a new “program files” folder in another partition when the free space on the OS installation partition becomes too small, or for example notifies the user about the problem and asks the user to choose the partition. (In all of the above variations the other partition can preferably be of course on any of the available disks and not just on the same physical hard disk—if there are more than one hard disks installed, and preferably in the new partition the relevant file or files and/or directory or directories are preferably marked as belonging to the OS or partition which created them or at least there is some other information which identifies the OS and/or partition which created them). Similarly for example when downloading one or more files in the browser, preferably the browser calculates in advance if the free space in the target partition is sufficient for all the files that are currently being downloaded into it (almost always the size of the downloading file is known in advance so the browser can easily calculate this), and if there is not sufficient space then preferably the browser automatically suggests to the user to transfer one or more of the downloaded field into another partition with more free space. Preferably the browser runs this check for example each time when the user request to download another file, so that preferably the total predicted space of the files that are already being downloaded into the target partition is preferably already deducted in the browser&#39;s calculation from the available free space of that partition, so that the browser preferably does not even start downloading a new file into a partition were the predicted free space will not be sufficient but instead preferably recommends to the user in advance a partition with more free space (preferably the partition with the largest free space) and/or asks the user to choose it. But since for example the size of the partition can become smaller during the download also for other reasons (for example if the swap file is also on that same partition), then preferably the browser also runs this check at least once in a while during the download even if no new files are added (for example at least if the free space is less than a certain relative or absolute threshold), and if the browser finds that now the space will no longer be sufficient to complete all the current downloads, preferably the browser can even for example in the middle of downloading files for example suggest to the user automatically to redirect one or more of the file that are currently being downloaded—into another partition (and preferably if the user is away than, at least if the space indeed runs out, then preferably the browser automatically puts at least part of at least one of the downloaded files in another partition (but preferably the entire file), and preferably lets the user know about it for example by an automatically displayed message when the user returns. The switch to another partition while in the process of downloading the file is preferably done by any of the methods described elsewhere in this application for making such a switch in the middle of downloading, or for example the browser transfers to the other partition one or more of the file it already finished downloading. Another problem is that for example in Vista build 5728 a problem with the sound blaster drivers can make the OS become unable to go back to previous restore points or to generate new restore points, giving a message that “Windows cannot create a shadow copy do to internal error in other system components. For more information view the event log” (and when viewing the event log the entry shows for example “ASR Error: Failed to collect critical information for ASR Backup. Reason: Unable to obtain disk information for device  0  (Win32 error code 0x15)”. So this is preferably improved so that even if such errors occur, preferably the system ignores it and at least enables generating new restore points (even for example without the problematic part) and/or going back to previous restore points (since no new information is needed for going back to them so there is no reason why this error should prevent going back to a previous restore point—especially if it is a restore point which was created before the problem started). Similarly, if the user for example wants to uninstall more than one program at the same time (for example in the control panel), preferably the user can mark multiple programs (for example with the convention of shift or control pressed while selecting items) and then preferably all the marked programs are uninstalled automatically (preferably one after the other). Another problem is that for example in Windows XP if there is some problem restoring the system to an earlier state then the system merely states that the system cannot be restored to the requested restore point but does not give any additional data. So preferably his is improved so that in such cases the system also displays preferably the exact problem or problems that prevented the restore and preferably also offers the user various solutions, such as for example fixing the problematic element from a different restore point, which is preferably recommended automatically by the system, and/or for example the system can preferably check automatically if the same problem exists in other near restore points and can then for example recommend to the user the closest next restore point or points which can be used without the problem. Another possible variation is that if the user for example requests to restore the system to a specific restore point and the changes his/her mind even after the restore process has already started, preferably he/she can press some abort key or for example click on some abort icon or menu option, which preferably causes the system to instantly stop the restore process and copy back the relevant system files from the copy of their state before the restore operation was started, and preferably without any reboot. This is much better than the prior art, in which the user would have to wait until the entire restore has completed, which includes also a reboot in the process, and the user could only then undo it or request a different restore point. Another possible variation is that preferably the system enables the user for example to correct or add to the description of restore points which were already created—for example if the user discovers later that he/she made some error in the description or forgot to add something.   10. Another problem is that for example in MS Word (all versions) if the user is within the header field and clicks on some position on the normal text of the document the user cannot continue to work on the position he/she clicked on in the normal text unless he/she clicks again or clicks on the close button, and when then the user is returned to the previous position where the cursor was before entering the header and not to the position which the user clicked upon, and similarly the same occurs when the user tries to enter the header field after working on the normal text of the document (so actually the user has to click THREE times in order to get where he/she wants in the other field, which is very inconsistent with the normal experience of simply clicking anywhere the user wants to go in the document. So preferably this is improved so that a single click can let the user jump between the header and normal text or vice versa, and preferably directly to the position on which he/she clicked (preferably of course when the user is in the header, the header indeed becomes more alive and the normal text more gray to indicate that it is a different field, as is done in the prior art, but that the hassle of having to click 3 times in order to get anywhere when moving between these fields is preferably avoided by the above improvement. Similarly, for example in Word 2007 it appears very inefficient that the user has to click on the menu tab handles above the ribbon in order to see the related items on the ribbon instead of being able to simply hover over it with the mouse. So preferably this is improved so that merely hovering with the mouse over the tab handle (for example in Word 2007 or in future versions of Word or in other word processors or other applications that use a ribbon) automatically shows the related items on the ribbon without actually having to click on the handle, and preferably this is done instantly, without for example having to wait for example 2 seconds over the first tab handle or having to click on one of the tab handles in order to get started in this mode (and/or for example the user can choose if it will work based on hover or he/she needs to click on the tab handle). Preferably the related items that belong to the tab handle over which the user hovers remain visible as long as the user does not hover over another tab handle, and this means that after the related items appear on the ribbon, if the user wants to click on one of these items on the ribbon the user preferably has to move the mouse through then bottom of the current handle and thus enter the ribbon and start moving over it to the desired item. (Although in the 2 nd  Technical Refresh of Word 2007 of Mar. 13, 2006 Microsoft added the ability to use the mouse wheel in order to scroll through the tabs handles, this is much less efficient since it is harder to stop exactly on the tab handle which the user might have in mind. In addition this is problematic because the scrolling ends when the user reaches one of the two ends, so the user has to change direction each time. So preferably this is improved so that the scrolling becomes cyclical, so that after the last tab is reached on the right preferably the next tab is again at the extreme left tab, and vice versa when reaching the extreme left tab handle when going in the other direction). Another problem is clear lack of consistency in various items within the ribbon itself, so that for example in some of them hovering over them will show a direct temporary effect on the current paragraph and on others the user has to click. For example when hovering over the style samples the preview works but when hovering over the 4 alignment icons (The vertical stripes that represent Align left, align right, align center, or align both ways) nothing happened and the user has to click on them. So this is preferably improved so that the same rules apply for example for all the features or at least all the similar features (for example all the changes that can instantly be displayed visually, such as for example changing the alignment), and preferably all the visible effects due to hovering on some option become available instantly. In addition, preferably the explanation bubbles which appear when the user hovers over some menu options preferably appear instantly and not after 2 seconds and/or at least the user can preferably easily change these time definitions. Similarly, preferably any submenus are opened automatically when hovering with the mouse over the options that open them instead of having to click on them (and preferably this is done instantly without having to wait 2 seconds), so that for example when hovering for example over the “Change style” option in the ribbon that associated with the “Write” tab handle, preferably the submenu of the options appears preferably immediately without having to click on it for the submenu to show, preferably together with the explanation bubble, which preferably becomes integrated for example at the top of the sub-menu that opens, and for example hovering over the “Switch windows” option within the ribbon associated with the “View” tab handle preferably immediately shows the menu of open Word windows, or for example hovering over the “Columns” option in the ribbon associated with “Page layout” preferably shows immediately the pull-down menu that open, instead of having to click on it in order to see the submenu, and then for example hovering over options in this submenu preferably instantly shows their effect preferably on the section with is currently visible on the screen, and for example hovering over the option of “Chart” or “Table” in the ribbon associated with the “Insert” tab handle preferably instantly temporarily adds a preferably small chart or table at the current cursor position as a preview, and at the same time preferably also shows the submenu of available table or charts, and then preferably hovering over any of them (for example in the “Quick Tables” sub-menu) preferably instantly changes the preview table or chart into that option, and since this is just a preview, of course when moving to another option on the ribbon the temporary preview table or chart is preferably automatically removed if the user hasn&#39;t actually chosen anything by clicking on it. Another problem is that for example when clicking in Word 2007 on the “WordArt” option and thus creating for example 3d colorful fonts with shadows on the marked section, these special fonts become an image and are not further editable directly at text, so that in order to further make changes in this text the user has to right-click on the image and enter a special window that enables the user to edit this text, which is inconsistent with normal editing regardless of font shape or size or color. So preferably this is improved so that the cursor can be moved to any position within this text by normally clicking on it an then preferably the user can edit this text normally in place like any other text (such as for example deleting or adding characters at the position the cursor is on. (This is preferably done by creating instead of a joint image for the entire marked text, a separate image for each character (or for example 2-3 characters if the shadow for example effects also for example the next 1 or 2 character on the right), and preferably updating only the affected characters on the fly as the user types, so that the other characters after that are merely shifted in position and do not have to be redrawn. And preferably, like the above examples, preferably the available styles of the “WordArt” option on the ribbon are preferably shown instantly when the user hovers with the mouse over this option, and then preferably hovering over any of the actual styles in there is preferably instantly shown as a preview over the currently marked section of the document (if no section is marked then preferably for example only the current word or line is affected). Similarly preferably for example when hovering over the various watermarks available preferably a preview of the watermark on the viewable text is preferably instantly shown without having to click on it, and in addition preferably the user can also choose for example the color of the watermark. Similarly, preferably for example hovering over the Italic or boldface or underline icon preferably automatically shows a preview of that style for example on the current marked section or for example on the current word or current paragraph, etc. Another possible variation is that for example if no specific section is marked then preferably all or most of the preview effects the entire section that is currently visible on the screen (preferably until the new formatting fills the screen—for example if the fonts become bigger). Another problem is that since the ribbon can change fast and there are many submenu options, the user might at first forget how he/she reached some options that he/she already found. So preferably the user can for example click on an icon or top menu option which opens some command history which preferably opens in a pull-down menu and preferably shows the user automatically the most recent commands that he/she used, preferably sorted automatically by recency and/or by frequency of use (which is also good of example simply for faster access even of the user does remember how to reach these commands). Another problem is that for example Word 2007 allows the user to save documents as pdf files, but when reopening such saved files or other pdf files the user cannot edit them anymore. So this is preferably improved so that preferably pdf files that are opened by Word are preferably automatically converted to a normal doc format which can be edited, and/or for example when saving a Word document in pdf format preferably additional information is automatically saved which complements any additional data that might be needed for editing the file (for example within hidden comments within the pdf file and/or for example though separated linked files). Another possible variation is that for example if the user tries to open for example a word processor file or for example a video file and does not find it for example because he/she does not remember the correct directory where it was saved or the exact name, preferably for example the word processor or the video playing application (or other relevant application) or the dialogue box can preferably automatically for example look for the file in all the other directories which the user recently edited or saved such files in or at least in the directories which the user most frequently used (preferably this list is kept automatically for example by the word processor or by the relevant OS service) and can preferably automatically show the user any other such directories where the file does exist, or for example this automatically activates the desktop search for the file and/or for example displays all the directories where such a file or a similar file exists, for example based on the application or the dialogue box automatically querying also for example the desktop search in such cases.   11. Another problem is that for example when creating an automatic table of contents in Word the user can only create one such table since there is no way of marking headers for a separate table, so for example the user cannot generate this way also an automatic list of all the tables and/or figures separately from the normal table of contents if the user wants also the table of contents. So preferably this is improved so that the user can create automatically more than one table. This is preferably done for example by letting the user use a different header style for example for items that go to the separate list of tables or figures and thus these items will not show up in the normal automatically generated table of contents. Another possible variation is that the list of tables or figures can preferably be generated automatically by the word processor itself without the need for the user to use a special header style for those entries. This is preferably done by simple heuristics so that for example any fully underlined paragraph which starts with the word “Table” or “Figure” or “Fig.” and especially if it consists of a single sentence and/or is center-aligned and/or is followed by an image is preferably automatically picked up when the user requests to generate or refresh the automatic list of tables/figures (preferably also with automatic page numbers) and preferably the user can for example go over this list and remove any items which were added there by mistake which the user does not want where or for example right-click explicitly on some line in the normal text of the document which should have been added to the list and for some reason was not picked up automatically and for example choose an option from a menu to add it to the list of tables/figures, and then the word processor preferably remembers these additions or deletions and keeps the list accordingly also when next refreshed. Preferably there is a default list of default rules, such as for example starting with the words “Table” or “Figure” or “Fig.” and preferably being at least underlined or for example also having to be center-aligned, and preferably the user can go over the list and for example mark or unmark each of these rules or add additional rules or change the catch words instead of “Table” or “Figure” etc. (In case of a bilingual word processor, such as for example Word in the English-Hebrew version, preferably the parallel Hebrew words are also pre-selected there and the user can also change them if needed). Another possible variation is that a normal automatic table of contents can also be generated automatically by using similar heuristics without the user having to format any lines in advance as headers, for example by the word processor picking up automatically all 1-sentence paragraphs that are underlined from their start, and/or only lines which start with digits and/or single letters separated by dots. Since the menu hierarchy is typically reflected already in these letters and digits at the start of such lines preferably the hierarchy of the table of contents is also created automatically from this (i.e. preferably according to the number of typically single letters and/or for example single or double digits each followed by a dot, typically at or near the beginning of the line, Such as for example “A. Abstract”, “B. Introduction”, “B.1. Historical background”, etc.), and if there are any mistakes the user can preferably correct it easily for example by dragging an item in the automatically generated table of contents left or right in order to represent its proper level in the hierarchy (in which case preferably the item jumps each time an appropriate step according to the direction in which the user is dragging it, so that preferably it stops automatically at the next level unless the user continues to drag it), and then preferably the word processor remembers this automatically and keeps the moved items at the correct level in the hierarchy the next time the table of contents is refreshed (and preferably of course automatically corrects the headline to the appropriate automatically generated fonts for the new level in the hierarchy, preferably both at the table of contents and at the corresponding headline in the document&#39;s text itself), unless the user changes it again explicitly or for example changes the letters or digits at the beginning of the relevant line in the actual text. Another possible variation is that if the user for example decides to makes changes in the order of clauses and/or order of chapters, for example after looking at the automatically generated table of contents, and/or or for example change names of clauses or of chapters or their numerals, preferably the user can make such changes for example directly on the table of contents (such as for example marking a group of headers in the table of contents and moving them into another position in the table of contents and/or changing words or numbers), and then preferably any such changes are automatically implemented by the word processor also in the document itself to correspond to the changes which the user made directly through the table of contents, such as for example changing the corresponding words and/or numbers of the changed headline also in the corresponding headline in the text itself, and/or for example automatically moving entire sections in the text of the document itself to correspond with the changes which the user made in the table of contents. Another possible variation is that if the user moves in the table of contents headers which are numbered for example with numbers and/or letters (for example at the beginnings of the headers), then preferably the word processor can also for example automatically renumber the letters and/or numbers to correspond with the new positions (preferably with request for user confirmation) and then preferably after the user conforms it preferably the same renumbering is automatically copies also to the corresponding headers in the text of the document itself. This requires very little work in terms of programming this in the word processor, but can save a huge amount of time for the users and create a much improved user experience for them. Another possible variation is that if for example the user by mistake repeats the same clause number consecutively more than one and/or for example skips one of more clause number and/or for example otherwise breaks the normally expected sequence (for example with manual clauses or even in automatically numbered clauses—since sometimes cut &amp; paste of separate clauses can keep such anomalies)—preferably the word processor automatically marks this in a preferably conspicuous way as a possible error in order to draw the user&#39;s attention to this. Another possible variation is that an automatic index with page numbers, for example for the end of books, can be also similarly automatically generated without having to mark any specific words for it. For this preferably the word processor has a pre-defined list of Ignore-words (such as for example “a”, “the”, “I”, “you”, “he”, “him”, “her”, etc. and other common expressions which should not normally be in an index), and when the user requests the automatic index, preferably all the words which are not in the Ignore-list are automatically indexed with page numbers. The user can then preferably go over the index and delete any undesired words or for example go over the pre-defined list of Ignore words and add or remove words from it or correct words, and preferably when the user removes words from the index they are preferably added to a specific Ignore list of that particular document (but preferably not the general Ignore list which will be used for other documents for example unless the user for requests that explicitly or requests to make the local list global) and thus are not picked up again when the user requests to refresh the automatic index. This is much more efficient than the current prior art, where the user has to manually explicitly mark words which he/she wants to include in the index, and the index generated by the above methods is much more complete and useful. Another possible variation is that for example this index of words with page numbers can be automatically generated for documents for example by activating for example the Google desktop search or a similar application on the document and requesting an automatic index with pages, and/or for example the desktop search automatically keeps also page numbers for words found when indexing documents. Another problem is that for some reason for example in word 2003 the user cannot change the left and/or right margins of the table of contents without screwing it up or change for example the line spacing within the table of contents (for example 1.5 line-spacing instead of single spacing) without being reset the next time the user refreshes the table. So preferably this is improved so that the user can change these parameters for the table of contents and they are preferably remembered so that the next refresh keeps the new margins and line spacing until the user changes them again (preferably this change is automatically corrected to keep the original ratio of the line spaces in the table of contents, so that for example if there is an additional line space for example between entries that are on the highest level of the hierarchy then preferably these spaces are automatically increased by the appropriate factor. Another possible variation is that the user can for example enter a command which enlarges or reduces the fonts in the table of contents by a given factor (for example by 10%, 20%, or other ratios) while preferably keeping the hierarchy of larger and/or otherwise more conspicuous fonts for higher levels in the hierarchy. For this preferably the word processor automatically picks for each level in the hierarchy the nearest font type and/or style (for example bold or not bold, etc.) and/or size in order to keep as close as possible to the appropriate ratios. Another possible variation is that the user can for example specify, preferably globally for the entire document, for example the exact font type and/or size and/or style for each level in the hierarchy, which preferably changes automatically all the relevant entries in the table of contents itself and all the relevant lines in the document itself. Another possible variation is that for example even without the automatic table generation preferably the user can mark relevant lines much faster than having to mark the whole line and then choose a style for it—for example by merely right-clicking anywhere on the line and choosing for example “add to table of contents” or “add to list of figures” from the menu that appears and then preferably the entire (preferably underlined) line or 1-sentence paragraph is chosen. In addition, preferably the word processor keeps track of what the user is doing and if for example the user is jumping over the document and marking lines for the table of contents (or is for example repeating some other activity) then obviously the user is trying to focus on building the table (or other activity) and therefore preferably the word processor offers these options for example on the top of a menu that preferably appears for example when right-clicking on the line and/or for example the menu becomes positioned so that the most likely option or options (for example according to the last few choices of the user) becomes automatically aligned near the clicked line, so that the user only needs the minimum mouse movement in order to choose that option (preferably this is done by shifting the menu itself up or down to appear so that the most likely option is closest to the line, but preferably without changing the order of the options within the menu, since the user might remember the original order in which the options usually show in that menu and thus changing the order itself might be confusing)(This can be done also for example with the normal prior art marking of headers, but as explained above the above variations are better and more efficient). Another possible variation is that the user can for example first generate a single table of contents normally and then for example mark multiple entries there (for example by pressing Shift for clicking with the mouse on a range or pressing Ctrl for clicking on single additional entries), and thus the user can for example mark all the entries that should be removed to the other automatic content—for example the list of tables and for example choose a menu option that moves them, and then preferably the word processor creates the other list and moves the marked entries there and remembers this so that when the user activated the next refresh the moved entries remain in the other list unless for example the user moves them back again. In addition, preferably when the user hovers with the mouse within the normal text of the document over a line which belongs for example to the table of contents or to the list of tables &amp; figures, preferably a small bubble or other visual indication shows up which indicates that it is an item in the table of contents, or for example all such lines are all the time automatically visually marked with an indication that they belong to some table of contents (such as for example automatically surrounding them, with some rectangle or color or other preferably conspicuous visual indication). Of course various combinations of the above and other variations can also be used. Another possible variation is that preferably the user does not have to manually update for example the table of contents every once in while but instead it is preferably updated automatically (at least for example the page numbers). In order to do this efficiently preferably the word processor updates it for example whenever the user jumps to the area of the table of contents in the document and/or when he/she requests to print the file or to save it (unless of course there were no relevant changes since the last saving or printing) or for example whenever there are changes in page numbers which make any of the lines that belong to the table of contents move near the page borders (for example by tracking their position) or whenever the user changes any of these lines themselves. Since the update usually takes only about 2-3 seconds, even if the user has for example just jumped to the area of the table of contents, by the time the user starts actually reading it the table can be already updated, so the first option is more efficient and therefore more preferable. Another possible variation is that for example when the user right-clicks within the word processor for example on an image that was inserted from a file preferably one of the available options in the menu is to show the path and name of the file from which the image was inserted. Another problem is that for example when the user splits the word processor into two windows of the same open file, for example in Word, the split can only be done vertically, so that one window is at the top of the screen and one at the bottom, which gives only limited view. So preferably this is improved so that preferably by default (or as a choose-able option) the split can be created into a separate tab or separate window (which has the additional advantage that preferably even more than one additional window or tab can be opened of the same file) and the user can preferably switch between them for example by the normal Alt-tab or Ctrl-tab instead of having to click each time on the other. In this case preferably the tabs or windows which are split views of the same document are preferably specially marked as belonging to the same document, such as for example a separate color and/or other identifier compared to the other windows or tabs. Another problem is that for example when using ̂Z or ̂y in one of the split views after doing something at the other, the position jumps to the other split view, and also some changes in the first view can shift the position in the second view, which makes it hard to keep track of the desired position. So preferably this is improved so that preferably any changes in one of the views do not change the position in the other view unless for example the text visible in second view itself becomes for example deleted or changed, and preferably there is a separate undo and redo buffer for each split view, so that preferably they behave like two independent windows or tabs, except that changes in any of them are preferably updated simultaneously also in the other view. This is of course even more natural in combination with the above variation of making the split into as separate window or tab. Another possible variation is that when the user jumps for example from a table-of-contents entry to the location of that section in the actual text itself, preferably the user can also automatically jump back preferably to the same position in the table of contents (for example like going back from “#” links in html pages), for example by clicking again on the relevant header in the actual section, or for example by pressing some control key, or for example by right clicking on the mouse and choosing for example an option to jump back to the table of contents, or for example a back button appears automatically for example at the section head in the text and clicking on it brings the user preferably back to that entry in the table of contents (but preferably the button or icon that leads back to the table of contents is preferable always there, not just when the user jumps there from the table of contents, so that preferably it appears for example as soon as the table of contents is updates with that item). Another possible variation is that preferably the user an use some control key to jump back to previous places in the document (for example similar to ̂Z but without undoing any changes), and preferably this for example goes back through every move the user made, or for example jumps at each step to a previous place where the user jumped from incontinuously (i.e. not by normally scrolling lines or pages), such as for example by search or by jumping to the end or beginning of the file or for example through the table of contents. Another possible variation is that preferably the user can also create for example internal links to other sections in the work processing document for example like internal links in html documents. Another possible variation is that preferably the user can for example click on some control which automatically makes him/her jump to the next element or clause preferably as defied according to the table of contents and/or simply the next element which is marked as a header that should be included in the table of contents even if the table of contents has not been updated yet (i.e. for example while reading clause B.3.2 the user can press for example ̂J (or some other control char character assigned for this) and instantly jump to the beginning of clause B.3.3), and/or for example similarly another control can be used to jump back to the beginning of the current clause and if pressed again the to the previous clause, etc. Another problem is that for example when marking headers for the table of contents in Word 2007 only 3 types of headers to choose from are shown at a time (for example “Heading1, Heading 2 and Heading 3” or “Heading4, Heading 5 and Heading 6”, so if the user for example has to mark some of the headers as level 3 and some as level 4 he/she has to use small arrows at the side to switch between these sets. So preferably this is improved so that merely hovering for example with the mouse over the appropriate arrows toggles the choose-able portions without having to click on the arrow and/or for example hovering over one of the choose-able headers or over their area preferably opens up automatically preferably the entire set of available headers (as explained also elsewhere in this application about menus or sub-menus in the ribbon preferably opening up automatically based on hover), or at east additional headers with lower or higher numbers (so that preferably hovering over the additionally exposed choices can put in view automatically additional options), and/or for example the list of displayed options is preferably automatically updated by the word processor according to the recent choices which the user toggled between, so that if the user for example used recently headers 2, 3 and 4, then preferably for example headers 2, 3, 4 are shown by default the next time the user goes to pick a header. The above variations can save a lot of time for example if the user is trying to quickly generate a complex table of contents. Another problem is that for example if the user tries to convert into a header a line which starts with an automatically generated letter or digit (typically followed by a dot), the conversion to header for example in Word 2007 automatically removes the automatic digit or letter from that line. So preferably this is improved so that in this case preferably either the automatic digit or letter remains automatic even in a header line (however within the table of contents itself this entry is preferably converted automatically to have a corresponding normal digit or letter) or for example also the converted line itself is automatically converted to have the corresponding normal letter or digit.   12. Another problem is that for example when the user adds a few English letters or words within a for example Hebrew line for example even Word 2007 automatically increases the spacing between this line and the previous line, even though usually there is no need to do this because the existing space is sufficient even despite the fact that some English letters may be a little more protruding upwards than the Hebrew letters. This creates a distortion in the spacing which is not pleasing to the eyes. (This can happen absurdly for example even if for example a dot (period) belongs for example to English instead of Hebrew, which shows how absurd and unwarranted this behavior can become). So preferably this is improved so that (at least as one of the options available to the user but preferably by default) preferably the spacing is increased only if for example the top of one or more of the English letters (and this is preferably measures by the actual present letters) becomes really too close to the above line in a way that makes it difficult to read, for example in relative terms and/or for example in absolute terms (such as for example less than 2 mm distance between the top of the letter to the bottom of the previous line, or any other reasonable distance). Preferably this small threshold limit is by default set to take effect only when it would really become difficult to read below it, and preferably the user can easily change these defaults). Another possible variation is that if it becomes too close the problematic letter or letters can be for example automatically shrunk height-wise for example up to a certain percentage and then for example increasing the line spacing is done only if the required shrinkage would be beyond the maximum allowed percentage. Another problem is that for example when a document that contains for example both Hebrew and English is automatically converted from DOS to Word, there is a problem that many times brackets and/or other punctuation marks (such as for example “.” Or ‘,’) and/or spaces at the border between the Hebrew and English words are wrongly interpreted by Word as belonging to the other language and thus assigned for example Hebrew fonts instead of English fonts or vice versa, which causes various irregularities such as for example the bracket reversing itself and/or a bracket or punctuation mark or space jumping to the wrong position—even for example when the English word or words remain in the middle of line and there are thus no problems of line-breaking rules. So preferably this is improved so that the conversion from the DOS document to Windows encoding for the word processor is preferably done by the word processor itself and preferably the word processor automatically compares (for example after the conversion of each such line) the result to the position of the punctuation marks and/or spaces in the original line (or for example takes this into account during the conversion itself) and so preferably avoids language changes of brackets and/or other punctuation marks if they cause such characters to move from their position in the original line to another position. Another possible variation is that if this happens the user can for example mark the relevant section or sections and then for example press some control which automatically converts for example brackets and/or other punctuation marks and/or spaces to the other language, and/or for example the user can also requests this globally for example for the entire document, and/or preferably this can be done as one of the options in the normal Find and Replace command, so that the user can for example request a global change of the entire document or of a marked section or sections and then for example confirm or decline any such change on the fly. Another problem is that similarly for example when entering search terms in Hebrew for example in search engines such as for example Google many times if the user uses quotation marks or brackets the text appears mixed up (for example with the bracket or quotation marks out of position). So preferably this is improved so that preferably the browser or the operating system preferably automatically takes into account the reversed direction of the language and preferably uses such special characters consistently with the direction of the language. Another problem is that for example even in Word 2007 in document that contain both Hebrew and English there are sometimes positions on a space or spaces at the borders between the languages where the user stands with the cursor on one position but using for example Delete (or sometimes Backspace) causes characters to be deleted from the other side of a word, or for example the user tries to add for example a period or comma but it is added at another place, or for example the user is trying to mark one or more characters but the marking jumps to other places, which can be very confusing or annoying to the user since when that happens it is not what the user intended, since obviously if the user puts the cursor at a certain position and tries to add or delete characters or mark something he/she expects that this will happen at that position. So preferably this is improved so that even if the space belongs to the other language and according to some rules is supposed to have such an effect when Delete or Backspace is pressed and/or when a character is added and/or when the user tries to mark something, preferably the word processor in such cases takes into account the fact that the user does not intend it to behave like that and therefore preferably the Delete or Backspace or adding of characters work in the expected manner regardless of if the space or the letters next to it belong to one language or the other. Similarly, preferably even where there are line breaks for example in the middle of a sequence of English words within a Hebrew paragraph (or vice versa) in the original documents which change position during the conversion or for example a line break becomes needed after the conversion or for example the line break remains within the English sequence but needs to be done at a different position, preferably the word processor during the conversion automatically assumes that the sequence of a few English words in the Hebrew paragraph (or vice versa for example a few Hebrew words in an English paragraph) is meant to be as it appears in the original document according to the correct breaking rules, and so preferably the word processor automatically decides the correct word order of the sequence by assuming that it was according to the normal rules in the original document and makes sure that this does not change during the conversion. (In this and in other places where Hebrew and English problems are discussed, of course the same or similar solutions can be done for example also for other cases where there are two or more languages which are written in opposite directions in the same document). Another possible variation is that for example the word processor format is changed so that it automatically uses always just one set of punctuation marks and/or brackets and/or spaces for the entire document instead of a double set in which such marks or spaces can be in either one of the languages of for example for each paragraph separately according to its main language (so that documents in the old format are preferably automatically converted when opened or saved in the new format) (for example by choosing automatically to convert such marks and spaces to the language which comprises the highest percent in the document, i.e. for example Hebrew in a document that is mostly in Hebrew and vice versa in a document that is for example mostly English, or for example by making this decision separately for each paragraph according to the main language of that paragraph), thus avoiding any further confusion, and preferably like in the above variation, when doing such automatic conversion preferably the word processor automatically makes sure that the positions of spaces and/or brackets and/or other punctuation marks remains the same as in the original document. Another problem is that for example in Word 2000 and even in Word 2007 a headline (i.e. a title line of a following paragraph or section) can become the last line at the bottom of a page, which clearly does not make sense. So preferably this is improved so that the word processor for example automatically transfers to the next page any last line which is preceded by at least a space of one empty line before it, which makes sense because it is also more convenient if a new paragraph does not start there, regardless of if it is a whole paragraph or just a stand alone line or short sentence. Another possible variation is that preferably the word processor automatically checks if the standalone line (preferably even if it sometimes extend for example for two lines) is a title or headline, for example by the fact that it is just one short sentence of typically 1 or at most two lines and/or by the fact that it is typically underlined and/or in boldface and/or in larger fonts than the surrounding text, and/or is marked as a header (which can also be used in an automatic table of contents), and then preferably treats is specially so that at least if it becomes the last line in the page with nothing below it, it is preferably automatically transferred to the next page. Another problem is that for example even in word 2007, for example when the user adds text and the document grows various figures or photos can move to a bottom of a page and become at least partly invisible without the word processor doing anything about it or alerting the user. So preferably this is improved so that when an image or photo or for example table or for example other shape which has to be kept intact moves at least partially out of the page, preferably the word processor automatically creates a page break before it but preferably puts the page break before the header that accompanies the shape, so that they preferably jump together to the beginning of the new page and/or the word processor preferably alerts the user when this happens and/or requests user confirmation before making the automatic correction. (Preferably for example the header of the figure or photo or table is automatically identified by any of the methods described elsewhere in this application for automatic detection of headers, such as for example typically a single line or single sentence which is typically underlined and/or in boldface and/or centered around the middle of the lines, and/or for example appears immediately before such a shape which typically comes with a header, etc.). Another possible variation is that preferably, at least as one of the options, the web browser can show page breaks when displaying web pages so that the user can know how it will look when printed, Another possible variation is that the user can enter for example a global command that affects automatically preferably all the headlines, such as for example automatically removing any period at the end of the headline and/or for example requesting better automatic incremental increase in size for headlines that are higher in the hierarchy, or for example making global changes for example on all the headers of the a specific level in the hierarchy, such as for example changing all the text marked as header1 for example into another font and/or another font size and/or for example another style, such as for example removing or adding boldface and/or underline, etc. Another problem is that when using automatic headers for example in Word 2007 there is in some header levels a clear discrepancy between the size of the automatically generated Hebrew font and the automatically generated English font for that header, and for example even in English the size of the automatically generated font for Header 3 is larger than the is generated automatically for Header 2. So preferably this improved so that preferably the relative size of the Hebrew and English fonts for the same headline preferably match (for example by the word processor keeping automatically statistical data about the relative average size of the characters in each font type and/or size and/or style and choosing this way a matching pair), and preferably the relative size of the fonts in both languages is preferably automatically chosen by the word processor to increase preferably in linear steps between each two levels of header so that levels higher in the hierarchy preferably consistently have larger fonts. Another problem is that for example if there are too many levels in the hierarchy of headers (for example when there are 4 levels or more) the automatically generated fonts for the lowest level of headers can become the same size or even smaller than the normal text, which is absurd, at least for example with the automatically generated Hebrew fonts, for example even in Word 2007. So preferably this is solved for example by automatically generating for example default preset levels in which the fonts are larger for each higher level in the hierarchy and yet even the lowest level is larger then typical text (for example up to a reasonable limit of a number of levels which is very rare and unlikely to exist—such as for example 7 or 8 layers or other reasonable limit, and assuming for example that normal text size is usually 13 or 14 at most), and/or for example the word processor automatically adjusts the automatically generated font size of each level also according to the numbers of levels that are used in the document, so that for example if there are only two header levels in the document then the higher one gets the size normally allocated to Header1 (for example even if it is not defined as header 1, or for example according the default size for the requested level of header) and the second gets some middle size or the normal size for that level, or for example if there are more levels than normal then for example the word processor preferably steps up all the relevant headers in size accordingly so that preferably the lowest level is still sufficiently larger than the normal text, and preferably taking into account also the size of the most common text in the document or for example the size of the text in the most relevant paragraph or paragraphs that follow the header (so that for example if most of the text is size 13 and there are for example 5 levels and for example the default sizes are for example best suited for example to 4 or 3 levels, then preferably each header level automatically gets the size which would normally be allocated to a higher level and the highest level or levels can automatically become larger than the size that it would normally be allocated if there were for example only 2 or 3 or 4 levels. Another possible variation is that the user can for example enter global commands, for example in the Find and Replace window, to switch between marks in different languages, for example based on various relevant criteria, such as for example Replace all English commas or for example dots to Hebrew Commas or dots, for example on condition that it is between two or more Hebrew words, or for example such replacements are preferably automatically done by the word processor itself, since obviously it does not make sense to create such a mixture of punctuation marks of English between Hebrew word or vice versa. Another problem is that for example when inserting one or more English words within a Hebrew paragraph once in a while it is very inconvenient to have to press each time Alt-shift on the left and afterwards on the right. So preferably this is improved so that for example by merely entering a single character in a capital letter in English (which simply means having to press Shift while typing the letter) preferably if the user continues to type letters for example without a space or even after a space the next letters by preferably by default become English for example at least until the next space is pressed or for example until the user jumps to the end of the line (for example by pressing the End key) or for example until the user presses escape or some other preferably single key, which preferably also makes the cursor jump automatically to the left of the English text where the user would normally continue typing in Hebrew after the English text, and preferably in this case the End key or other key preferably also adds automatically a space after the left edge of the English text so that the user can start typing in Hebrew immediately without having to add also the space manually. This is very efficient since almost always entering a few English words will start with a capital letter, and for example even if the user wants the first letter to be a small letter it is much faster to correct it with backspace than to go through all the trouble of switching languages through the Alt-tab. (Although Word 2007 enables part of this effect if the option “Automatically switch keyboard to match language of surrounding text” is enabled, in Word 2007 the user needs to enter at least two consecutive capital letters in English in order to generate the automatic switch to English, and most users are not even aware of this possibility, and for example pressing End in this state in Word 2007 makes the cursor jump to the left of the English text but does not automatically add a space). Another problem is that for example even in cmd windows there is a problem of ignoring the user&#39;s attempt to change for example English capital letters to normal letters or vice versa for example when copying over a target file with the same name which has a different choice of capital letters, so that for example if the user copies a file such as for example pre-faq.htm from another directory over a file named for example Pre-FAQ.htm, then the capitalized letters remain the same instead of changing as the user intended, which can be very annoying, especially since there is no indication to the user that this behavior occurs unless he/she checks again the target directory. (This can be very important especially for example with names of web files which the user then transfers for example through ftp for example to Unix servers, since the correct capitalization of letters is important there, otherwise it is considered a different file. So preferably this is improved so that if the target file is the same name (except for letter capitalizations) preferably the copy automatically creates the capitalization of the file which is being copied, and/or for example the user is automatically notified about the different capitalizations and asked to choose if to change the capitalization according to the file being copied or leave it like the target file was before. A similar problem exists for example even in Word 2007, so that if a user for example renames a file to change capitalization of letters, Word still shows the file for example in the list of recently accessed files with the old name and if the user clicks on this link in the recently opened files then saves the file then the file name is automatically reverted to the old name. So preferably this is improved so that when the word processor shows a list of recently opened files preferably it automatically checks first in the directory if the capitalization has changed and if so preferably automatically changes it when showing the file name in the list of recently opened files, or at least for example updates is automatically according to the updated current name in the directory if the user clicks on it to open the file. Another problem is that for example even in Word 2007 the user cannot automatically see which underlined lines in the text are headers, and even for example clicking on the line shows if it is a header only if the ribbon is on the Home tab. So preferably this is improved so that preferably the headers are preferably automatically marked by the word processor visibly as headers, preferably including their level, preferably even without the user doing anything or at least based on hover, and not only when clicking on the header, and/or preferably the ribbon jumps automatically to the home tab or otherwise displays the header level if the user hovers over a header line or clicks on it, and/or preferably the header is marked as header by a visible indicator at or near the line itself, such as for example a special type of underline and/or color which preferably shows all the time and/or for example a bubble which shows for example when the user hovers over it. Another problem is that for example when making global changes for example in Word with track changes On (even in Word 2007), the word processor marks entire words as having change even if the user for example just changes one letter, such as for example changing all occurrences of the word ‘Online’ to ‘online’ or vice versa, which can be annoying and confusing since in reality only one letter has changed. So preferably this is improved so that when performing such changes preferably the word processor first tries to use automatic comparison between the search string and the replacement string (preferably within the dialogue box where the user defines the search string and the replacement string before even starting applying replace the command) so that preferably the word processor determines in advance the minimal amount of change that represents the action (which is similar to what is done when comparing changes between two strings), and then preferably when applying the action preferably uses this to mark accordingly only the minimal change each time the replacement is actually applied to text in the document, so that for example in the above example the only marked change will be Oonline (or oOnline, but preferably the strikeout appears before the new text and preferably the user can also change the default which determines if the strikeout will appear before or after it). Similarly, even in word 2007, if the user for example marks or finds through search the letter O in the word “online” and then types ‘o’ with track changes on, again the entire word is marked as erased and reentered, instead of only the appropriate letter. So preferably this is improved so that, like in the above solution, preferably the word processor marks only the relevant section or part of the word as changed.   13. Another problem is that for example even in Excel 2007 the user cannot request for example to automatically reverse the order of data for example vertically or horizontally or for example reverse the direction in the displayed graph, so preferably the spreadsheet is improved so that the user can preferably easily make such reversals, for example as one of the options in the menu or for example when clicking with the right mouse button. Another problem is that for example Excel 2007 assumes automatically that the order of clicking on columns is important, so that for example if one of the columns is the date and one of the column is for example stock prices, if the user clicks first on the date column and then on the stock prices column and then requests to insert a graph then the spreadsheet displays it OK with the date horizontal, but if the user clicks on the columns in the opposite order then the graph becomes something entirely different which does not make send. So preferably this is improved so that for example at least if one of the columns which the user clicks on contains dates then preferably the spreadsheet assumes by default that the dates should be used on the horizontal axis regardless of the order the user clicked on the columns, and/or for example the spreadsheet preferably asks the user for example which column to put in which direction. Another possible variation is that preferably the user can for example click on an area in the graph and/or for example mark a section in it and then click on it and then preferably the spreadsheet automatically displays a zoom-in of the marked section or of the area around the point where the user clicked on, so that the user can preferably instantly see more details in the area that interests him/her, and/or for example the zoom can be automatic even for example based on hovering with the mouse over a section of the graph without having to click on it, or for example the user can drag a magnifying glass tool which automatically enlarges the area it hovers over. Another problem is that for example in Excel 2007 enlarging the graph for example by clicking Ctrl and moving the mouse wheel apparently only increases the size of the image but does not add additional detail. So preferably this is improved so that such increase of the entire graph and/or for example the zooming in of a section in the graph preferably automatically increases also the resolution of the graph (or of the relevant section) accordingly, preferably by showing more data points and preferably if there is a time scale preferably adding more values to the date scale, so as to increase the time resolution. Another problem is that if the user for example deletes a graph for example in Excel 2007 the ribbon automatically jumps back to the ‘home’ tab eventhough most likely the user will try again another graph. So preferably this is improved so that the ribbon preferably at least in most cases does not change its forefront tab automatically.   14. Another problem is that for example if the user tries to print something for example from the word processor or from the Web browser and for example chooses a printer and presses Enter quickly, if the user hits by mistake the ‘Del’ key together with the ‘Enter’ key at the same time, so that the ‘Enter’ key is actually hit for example a split second after the ‘Del’ key (or for example the user Hits the del key by mistake without noticing and then presses ‘Enter’ to confirm without looking, thinking that it is a normal confirmation for printing), then the printer becomes deleted and the user cannot undo this except by reinstalling the printer, which sometimes might cause various problems or by using System Restore. So preferably this is improved so that the deletion of the printer (and/or preferably also for example the deletion of other things or other activities) preferably cannot be confirmed by pressing Enter but only for example by clicking on a specific option that says for example ‘Delete’. Another possible variation is that for example any deletion of components or drivers or other critical activities which the user does can preferably rolled-back automatically preferably instantly, preferably by keeping automatically a roll-back log of preferably all such changes, as explained also elsewhere in this application, so that preferably the user can instantly undo his/her last action or actions without having to resort to System Restore, which is more dangerous and requires a reboot. Another possible variation is that preferably even System Restore, when needed, can preferably be done at least in some or in most cases by instant Reset, as explained elsewhere in this application, without needing to actually reboot. Another possible variation is that preferably for example system restore ad/or other risky operations are preferably done in transactions so that preferably a copy of the state before the change is automatically kept and if for example due to power failure or some other problem the transaction did not complete (as indicated for example by the existence or non existence of a flag which is updated only if the transaction has completed properly, preferably for example the system is automatically restored to the state before the transaction, for example after the next boot or after the process is supped to have completed. Another possible variation is that preferably for example the OS automatically takes notice and remembers whenever the user changes the printer for example in an application such as for example the word processor or the browser of the pdf viewer, and then preferably this becomes the default printer preferably also for the other applications or at least for similar types of applications (such as for example the above 3 examples), so that the user does not have to change the default printer manually for each one of them and does not have to enter the printers setup in the control panel for this. Another problem is that if the user for example wants to print just one page or a few pages from a large file (for example in a file of 200 pages or more) and sends by mistake the whole file to printing and then for example presses the Cancel button on the printer, it can take quite some time to cancel it—for example even 1 or 2 minutes or more if it is an inkjet printer. So preferably this is improved so that preferably when the user presses the Cancel button preferably the printer preferably instantly sends back to the computer a code that notifies the OS or for example the print driver to cancel the printing, so that preferably the print driver also stops sending output to the printer preferably instantly, and at the same time preferably the printer drops preferably instantly all the data sent to it by the computer. Another possible variation is that if the user for example marks with the mouse one or more areas for example in the word processor or in a web page (or for example marks multiple items for example in a scroll list in a web page form) and then by mistake for example clicks with the mouse in a new area or does something else which erases the marking, preferably the user can for example press some control or for example some icon or option menu to undo the unmarking, so that the last marking status is restored, and/or even the marking can be moved back or forward over multiple steps (which means that preferably the relevant applications or for example the OS preferably automatically keep a log of the marking).   15. Another problem is that for example in Windows XP when the “all programs” pop-up list which is activated through the Start menu becomes full, additional programs are just out of the screen and are not shown at all, which can be very annoying and/or confusing. Although the user can ask to sort the programs alphabetically instead of by order of appearance, this does not help if the newly added programs start for example with a letter too far away in the alphabet, and anyway, this is not a real solution since either way some programs will still remain out of view. Another possible variation, as mentioned elsewhere in this application is for example to enable the user to sort the programs for example by descending order of recency so that the most newly added programs appear first, and/or for example to choose this as the default order also for the programs that will be later added, however this again still does not solve the problem of having at least some programs become invisible (Similarly, when choosing for example alphabetic order preferably new items are afterwards automatically added according to this sorting order without the user having to request to sort again alphabetically after they are added, unlike the current XP, in which even after sorting them alphabetically new programs are still added at the end). So preferably this is solved for example by creating in such cases automatically for example a horizontal bar which moves to scroll the list of programs sideways, and/or for example if the user moves the mouse for example to the right edge of the screen the list scrolls automatically to show what is next on the right, and preferably there is an indication in advance that the list extends beyond the edge of the screen. Another possible variation is than the system can for example automatically enable adding more programs for example by automatically reducing the width of each column for example in advance or on a need basis (for example by automatically folding long names into two or more lines and/or showing only part of them (and in such cases for example when the mouse hovers over them preferably the whole name for example is preferably instantly shown for example in a pop-up bubble), and/or for example making the letters at least in the long names automatically thinner and/or smaller, and/or for example automatically reducing the distance between the lines of text in the list of programs. Of course various combinations of the above and other variations are also possible.   16. Preferably the user can logically disable or change the function that pressing various keyboard keys has on the OS and/or on any programs that are running, such as for example the “Windows” key, since if the user is working for example in text mode in a DOS window, pressing for example by mistake the “windows” key causes the display to switch and can be very aggravating. Similarly, if the user buys for example a new keyboard and some keys (such as for example the ESC key or the CTRL key) are not in the place that he is used to, preferably the user can simply redefine these keys, for example by marking the changes on some virtual keyboard that the system displays, so that for example these keys will switch places, and then the user only has to switch physically for example the external plastic caps of the keys that he changed logically (or for example glue new labels on them), and then the change is complete (This means that preferably the keyboard keys are mapped though the inner conversion table). Another problem is that for example in portable computers some keyboard keys do not exist, such as for example the side keypad, which can be very inconvenient to users that are used to it, and also for example in some text editors the side ‘*’ is the Undo button and for example the side ‘-’ key copies and deletes a line, but the normal ‘* and ‘-’ keys don&#39;t have this function. So preferably the user can also redefine for example some keys for example on the right to become for example the keypad keys—but for example on condition—for example when another key is pressed or some switch is moved, and/or for example the keyboard in the portable computer is defined like this in advance and preferably the relevant keys have also the additional keypad marks on them, or for example the original ‘*’ and ‘-’ automatically become the keypad keys when the other key or switch is pressed. Another possible variation is that the user can for example add to the portable computer (for example when it is used on a desk) for example a mini-keyboard which completes for example the side keypad and/or any other keys—for example using the normal plug that enables adding a keyboard to the portable computer, except that preferably the complementary keyboard for example sends a special code or for example has a somewhat different configuration of the connector, that tells the portable computer not to regard it as a replacement keyboard that disables the portable&#39;s built-in keyboard but regard it as adding certain keys to the internal keyboard. This can be more convenient and space-saving than adding a full keyboard that is used INSTEAD of the portable&#39;s built-in keyboard.   17. Preferably the dynamic linking possibilities are improved so that the user can call and use any Windows DLL from a DOS program (preferably in an extended DOS environment) and/or vice versa, so that preferably the two environments are integrated seamlessly in memory, so that Windows modules and DOS modules can preferably transfer data between them without having to use for example intermediary file storage. This way, for example a program that needs to use the TWAIN interface to work with various scanners can for example have one or more modules that run in the Windows environment and can for example connect to the TWAIN DLLs and for example have also one or more modules that run in DOS mode (preferably extended DOS) and can thus have backward compatibility for example with absolute memory addresses or other functions that are available only in DOS mode. This can be done for example by defining appropriate stubs and/or API interfaces that bridge between the two types, including for example any necessary conversions that are needed for compatibility, and/or using for example various sockets and/or client/server connections within the same computer.       
 
         [0063]    Another preferable improvement is that for example when Faxes are received directly into the computer by a fax card, preferably the Fax program and/or the OS is improved so that if for example a fax-transmission has been cut-off because of some error and the sender wants to send again only the remaining pages, preferably the program and/or the OS can automatically identify this (for example by identifying that this is from the same source and within a short time after the previous fax), and then preferably the continuation fax is appended to the end of the previous fax and/or the program at least groups them together and/or notifies the user that two or more faxes appear to be a continuation of the same fax from the same source. Another possible variation is that the receiving fax card can for example automatically return to the user (preferably by improving the communication protocol so that this feedback can be received without having to call back the user) a unique return code that preferably includes a time and date stamp and a serial number of the communication (as described also in U.S. patent application Ser. No. 10/756,839 by the present inventor), and preferably the user can add this code on the continuation of the fax, for example preferably digitally (if the fax is sent from another fax card, or for example as an additional code at the end of the dialed phone number if the protocol is improved to enable this), or for example as a printed number at the top of the first continuation page, together with a code that indicates that this is a continuation (in which case preferably OCR is used to identify this). Another possible improvement is that if the user for example sends by mistake in a normal fax or for example a combined fax-scanner-printer a page that is with the printed side facing away from the side that is scanned (unless for example if it is a double-side fax that can read both sides of the page simultaneously), preferably the system automatically warns the user that the page is empty on the scanned side (preferably the system determines this for example according to some threshold values). Another possible variation is that the user can for example choose an option on the fax menu which automatically also prints a photocopy of each fax page while it is being sent (or for example keeps it in memory and prints it for example immediately after the page is sent or for example after the entire fax is sent, or for example sends a copy of the faxed pages to the user&#39;s computer so that the user can for example view them on the screen and only then decide if he/she also wants to print them and/or for example keep the copy in an archive) and thus the user can immediately see exactly how the page was scanned and for example see immediately if there were any scanning problems. Another possible improvement is that if the user has for example a combined fax-scanner-printer connected to the computer preferably the OS is able to send faxes also directly through the attached fax-printer by sending it the data and telling it send is as fax instead of printing it. That is preferably done together with an appropriate enhancement in the attached fax-printer (preferably this is done by a simple change in the firmware of the all-in-one scanner/fax/printer and/or by adding the appropriate software to the computer). The pages can be converted to a fax image in this case for example by software in the OS or by the fax-printer itself. This has the advantage of better quality than scanning a printed page, and is useful for example if the computer does not have a modem/fax card installed in it or if the external fax/printer is faster than the fax/modem card. Another possible variation is that the user can for example use the combined fax/printer/scanner and/or for example even a normal scanner to send faxes directly through the Internet, preferably through the computer&#39;s Internet connection. This is preferably done, again, by a change in the device&#39;s firmware and/or by adding the appropriate software to the computer. This has the important advantage that the user can preferably send faxes directly and instantly the same as he/she would be sending them through a normal phone line, except that preferably the fax is sent through the Internet and is preferably sent to the receiving fax either directly also through the Internet (If the other fax is also connected to the Internet), or for example through a local gateway that converts it to a normal Fax transmission through a local phone-call, or for example it is received directly into a computer on the other side. (Of course, if the file exists for example as a Word document on the user&#39;s computer then using the scanner or combined scanned/fax/printer is not needed, however the main reason that people send a Fax instead of an email is typically to send a document that contains a signature or a document which does not exist on their computer). Preferably the user can for example add some special prefix to the phone number, which indicates to the sending fax that the call should be routed through the user&#39;s computer, and then for example, instead of really dialing, the image is sent to the computer for example through the USB or other connection that exists between them. Another possible variation is that the user can for example use a fax card or for example a combined fax-scanner-printer which is connected to the computer in order to send one or more pseudo fax images which are actually digital data (such as for example one or more pdf files or other convenient formats). This can be done for example by a special software that runs on the computer and/or for example by some firmware change for example in the all-in-one fax-scanner-printer, so that the computer can send to the fax-scanner-printer for example the special digital file or files for example alone or together with real images or scanned images (for example if some scanned cover forms or other scanned images are also needed), and when it is transmitted by Fax the sending device preferably uses a special code to tell the receiving device that one or more pseudo page images are actually a digital file, and preferably the receiving fax is either a computer with a fax/modem card or for example a combined fax-scanner-printer which is also connected to a computer and thus can transmit the digital file to the computer as a digital file, and preferably if a normal fax machine that can&#39;t handle such files responds then the sending device knows that the transfer of digital files is not possible and preferably issues some error code and aborts or automatically sends instead also the digital file as normal fax images. This can be used for example for sending applications or other documents to patent offices by Fax (which can enable for example user identity confirmation by the telephone&#39;s caller ID, without having to deal with digital signatures, etc.), while allowing high speed transfer almost at the same speeds of sending email, Even if the file contains for example a 100 pages, whereas a normal fax of such size might take even half an hour or more and involves the risk of for example some lines not being scanned properly without the sender even knowing this, and of course it also saves wasting of time on OCR recognition at the receiving side. Preferably this is accompanied by transferring also one or more CRC codes and/or other integrity data, so that preferably the connected computer on the receiver side (and/or for example the CPU of the receiving device itself) checks if the CRC and/or other integrity data fits the actual file that was received, and, if not, preferably tells the receiving device to return an error code so that the sending device can try to resend it. Another possible variation is that the sending device can for example automatically split the digital file or files to multiple sections if for example the file is too large for the desired size of each pseudo page-image. Another possible variation is that the two devices can automatically recognize each other, preferably already during the handshake, as having more than Fax communication capabilities, and thus for example can automatically (preferably at least when it is more suitable) switch to some other electronic file transfer protocol between them which is preferably more directly oriented to exchanging digital files. Another possible variation is that for example the fax logs automatically indicate near each communication for example also the resolution that was used in the transmission (for example standard, fine, super-fine, photo, etc.) and/or for example if the fax was in B/W or in color. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. Another possible variation is that when sending a Fax the sending Fax machine can preferably enter automatically into the sent page (and/or also display to the sender) the local time and date of the receiving Fax (for example by reading it from the receiving fax or for example by reading it automatically from the phone company or for example from the Internet, for example according to the called number). Another preferable improvement is that preferably the receiving fax machine (for example a normal fax or for example all-in one devices that contain a fax) is programmed by default (and/or at least the user can choose this option) to respond with fax sounds only if fax sounds are heard in the incoming phone call. This is very important since when the user needs the same line for fax and voice, if the user does not answer fast enough (for example if the fax is set to answer at the 5 th  ring and the user did not reach the phone fast enough) the Fax machine on the same line will interfere even in voice calls. Although the normal Fax protocol has been that the calling fax is supposed to wait for fax sounds from the receiver side of the phone call before making its own fax sounds, modern fax machines make these sounds when calling even if there is no fax sound on the receiving side, so, if the user chooses this option or this is the default, the only price is that some old stupid fax machines might not be able to send faxes to the receiving fax when the receiving fax is set in this mode, but it solves the problem of the user&#39;s fax interfering with incoming voice phone calls. Another possible variation is that the receiving fax is improved so that it is preferably able to automatically identify voice calls and thus avoids making fax sounds if it identifies for example human voice and/or stops immediately and gets off the line even if it started making fax sounds, as soon as it identifies the human voice. Another possible variation is that for example if the fax and/or the computer or other computerized device can also record voice messages, preferably the user can define routing of phone calls to separate virtual boxes according to the incoming phone number or numbers (for example according a list or lists of specific numbers, and/or according to ranges of numbers or even patterns with partial wild cards), and/or for example also according to voice patterns (such a for example pitch or other heuristic patterns that differentiate best between individuals), so that for example calls from a specific person can be automatically routed to a different area even if he/she hides his caller id. Of course, like other features of this invention, these features can be used also independently of any other features. Another preferable variation is that preferably the ability of the scanner/copier to overcome wrinkles in papers or for example overcome the black stripe that appears when scanning or photocopying books when the user can&#39;t press the book down strongly enough—is improved, preferably by adding at least one more light source in the scanner, so that shadows are automatically reduced. Another possible variation is that for example when using previous applications as basis for a new application for example in the EPOline software, preferably all the original data (including for example the details of the applicants and/or inventors, address for service and/or agent, and/or even for example priority data and/or the attachments, so that preferably the user can change or remove things if needed but can preferably use as much as he/she needs from the previous application, since in the prior art EPOline software the user has actually to refill everything from scratch even when “reusing” the pervious application as basis for the new application. Another possible variation is that for example the word processor or for example an external application can for example automatically split up automatically for example a word document of a patent for example into a separate file for each main part (such as for example Abstract, Specification, Claims and Figures), so that preferably the user for example only has to enter the name of the prefix of the files, such as for example BetWin630, and for example the word processor or other application can find the sections for example automatically (for example based on the title at their beginning and/or for example various heuristics such as for example identifying the structure of the claims section by finding automatically numbered paragraphs in which almost every paragraphs has the words “of claim” or “of claims” or “of any of the above claims” or a similar expression in it, or for example finding the section of the Figures according to being the only area of Figures and for example typically appearing after the claims section, etc.) or for example based on the user marking the beginning and/or end of each section for example once, for example like when marking Headers, so that preferably these marks enable finding easily the borders between the sections even after more text is added, or for example the user can add a few visible control codes which show for example the borders (such as for example #startspec and/or #endspec, #startclaims and/or #endclaims, #startfigs, etc. and/or any other preferably simple word or code which is preferably for example preceded by at least one characters that prevents confusing it with text that might normally appear within a section), or for example the user can define for example the exact text and/or style for example of the title beginning of each section, and then preferably the word processor or other application can automatically add names of the application parts to the prefix in order to create automatically the names of the automatically split files (such as for example ‘betwin630spec’, ‘betwein630claims’, etc., and/or can even for example automatically activate the command that converts or prints them for example into a pdf file, so that preferably the split files are automatically also copied for example into pdf versions. Another possible variation is that for example alternatively for example when filing a single pdf file for example with a program like the epoline software or for example with the EFS Web of the USPTO, preferably the application (or for example Java or Javascript in the browser) can preferably automatically for example identify the sections for example in a single for example pdf file that contains the entire application for example by any of the above described means and then can preferably automatically show to the user the identified start page number and end page number of each identified sections and preferably ask the user to confirm the automatically generated page numbers or correct them, and/or for example this automatic identification of the part is for example done automatically at the patent office itself for example by any of the above means. Another possible variation is that preferably for example after uploading and validating files in the EFS Web, if the user for example removes a file by mistake, preferably the web site allows him/her to press some control or icon and undo the deletion instead of having to go back to the earlier stage and define again the file.
       18. Another problem is that when the user searches for programs in the “Start menu” the installed programs are typically sorted by the order they were installed, and so in order to find a specific program the user might have to scroll over a large list if there are many installed programs. Although the user can for example request the System to automatically sort the list of installed programs in the start menu for example by alphabetic order, preferably the user has also additional options, such as for example to jump automatically to a given program in the list for example by typing the first letters of its name, and/or for example the user can enter a search string and the system looks for example for names that are at least similar to the desired name (in which case preferably all the similar names are displayed, preferably sorted by descending similarity to the search string), and/or for example the user can request to sort the programs there according to reversed date of installation, so that the latest installed software appears first, etc. Another possible variation is that there is for example a special log of installations of programs according to the order in which they were installed, which for example the OS or the security system can keep automatically, even if for example the program has not added itself to the list of programs of the start menu or to the desktop, which has the advantage that the user can easily find programs also in this case and/or find out for example about installations that occurred without his/her knowledge (this of course can work very well also with the rollback possibilities discussed elsewhere in this application). Another possible variation is that the user can for example request automatic sorting of the programs according to types, such as for example programs that deal with DVDs, programs that deal with music, Internet application, editors, etc., for example in the list of installed programs and/or on the desktop, which can be done for example by adopting a convention where each program contains such meta data about its main function and/or for example the system finds this info automatically for example according to the program&#39;s name in one or more Internet Databases. Another possible variation is that the user can for example move or copy for example functions that are available when clicking the left mouse button for example over the start menu (such as for example “explore”) to be available (in addition or instead, but preferably in addition) also when clicking with the right mouse button, or vice versa. This is important because sometimes the user does not remember if a certain option is available for example with the right click or with the left click or prefers for example that at least certain functions will be available for example by both clicks. Another possible variation is that for example when the user uses the explore window he/she can preferably for example add for example on the top line for example the file name with wild cards (for example f:\commnet\bet*) and then the explorer window preferably shows only the files who&#39;s names fit the pattern, for example like in the file open or save dialogue box. Another possible variation is that for example in the explore window and/or in the Open or Save file dialogue box and/or for example in CMD windows and/or for example in the Google desktop search or similar Vista indexed search, preferably the user can also use wildcards also for a drive letter and/or for the path or part of it, so that for example if the user types in a CMD window “dir ?:\mplayer” or “dir :\mplayer” it will show all drive letters which have a top-level directory named mplayer, and if the user for example enters in the top line of the Windows Explorer for example ‘f:\comm*\bet*’ it will list all files that fit the pattern which are in all the directories which start with “comm” in partition f:. (or preferably for example even if it is in a subdirectory of such a directory). Similarly preferably for example in a cmd window preferably the user can for example use wildcards for performing cd into a long directory name, for example by typing ‘cd prog*’, and preferably if there is more than one directory name which fit the wildcard then preferably the system for example shows the user the list of directories which fit it and asks him/her to choose. Another possible variation is that the user can for example type in a cmd window ‘cd’ followed by a directory name even if it contains spaces without the need to surround it in brackets, since the OS can know from the context that this is a directory name and that there are no additional parameters to this command and thus preferably interprets it intelligently as if the brackets were there around the entire directory name. However the above variation of being able to use a wild card is of course more preferably since it can save much more typing especially if the name is long, and so is the option of going into a directory also in a CMD window by clicking on the directory name with the mouse, as explained elsewhere in this application. Another possible variation is that preferably the user can use wild cards also for example when choosing files for burning on a CD or DVD, for example in programs such as Nero. Another possible variation is that the user can also for example use a date filter with the ‘dir’ command, such as for example ‘dir bet* after=01/10/2006’ or other similar formats (for example similar to the way that such date filters can be used with the pkzip program). Another problem for example in the new explore window of Vista is that since the top line now shows a series of elements, if the user wants to enter directly a path there he/she typically has to click on it first multiple times with the mouse before it will accept directly typing in the path. So preferably this is improved so that even a single click on this line is enough and then the user can directly type the path. Another problem is that for example both the Google desktop search and the instant search when clicking on the Start button in Vista do not work properly when one the characters which the user types do not appear at the beginning of a word in the file name or in the text which the user is searching for. So preferably this is improved so that at least for example for a match of some minimum number of characters or more preferably results are shown even if the typed text in not at the beginning of a word. Similarly, preferably the user can use this typing for example on the desktop, and then preferably the system for example displays the list of closest names as explained above and/or for example automatically indicates the most relevant icons, for example by making them brighter and/or making them move or flash and/or drawing visually attention to them by any other means. For example in Windows XP if the user types a letter on the desktop the system jumps to an icon beginning with that letter but when the user types the next letter the system jumps again to an icon beginning with the newly typed letter (and if the user repeats the same letter then the system jumps to additional icons which begin with that letter), instead of jumping according to a sequence multiple letters, so that if the user for example wants to repeat a search preferably another command is used. Also, preferably the chosen icons are conspicuously marked (for example by stronger light and/or flashing), since just darkening the icon a little bit like Windows XP does is not conspicuous enough so it takes time for the user even to notice what next icon is marked. Another possible variation is that for example the OS and/or for example some other software) can for example automatically change the color (and/or other attributes) of the text near the icons on the desktop, preferably for example in a way that creates maximum contrast according to the colors of the background at that specific location (For example the Azul background of Windows XP has some areas which are too bright for white letters and some areas which are too dark for black letters, but in Windows XP the text of the icons is always white). This can be done for example by choosing automatically black or white and/or other colors according to which has the better contrast with the local background and/or for example using some automatic XOR function. This can be done for example automatically for every pixel or group of pixels in the text and/or for example per letter or per word and/or for example all the text of the same icon has the same color, which means that in this case preferably for example the average background is taken into account and the average best contrast color is chosen for example for the letter or the word or the entire icon text, etc. Although Windows XP partially solves this by using some slight darker shadow below the white letters, which helps see it also on whiter parts, this can still cause fatigue to the eyes and make it harder to see since for example black on white is usually easier to recognize cognitively than white on black, and also the duplicity of the shadow can create some inconvenient feeling of lack of focus, and also but the user cannot choose a different color or for example sets of more than one colors. Although there are some utilities that allow the user to change the text color, as far as I know the choice is just one color for all the text. Therefore, another possible variation is that for example the user and/or for example the OS (and/or other software) can for example choose also to display text in different sets of more than one color for example by letting the user choose which color to use for the text and for example which for a shadow (or for example other effects) and/or for example the OS can choose two such colors automatically, for example according to any of the above methods. Another possible variation is that the user can for example change the color of the taskbar and/or for example choose between various skins for example with different patterns for example for the taskbar and/or for example for other elements on the desktop, such as for example the start menu. Another possible variation is that for example when Stereo display becomes available, for example the text of the icon and/or the icons themselves can be made to look as if they are for example protruding from the desktop, and/or for example such protrusion can be used as one of the options for emphasizing text for example in word processors and/or Internet browsers. Another possible variation is that preferably when 3d movies are displayed (for example based on red-green glasses or for example based on polarized glasses in which each of the lenses has a different polarization, or for example in various autostereoscopic systems based for example on lenticular element designs or other methods), preferably sub-titles are designed automatically to be displayed as if they are protruding in front of the screen and in fact preferably in front of any other 3d objects (or for example in a dvd this is preferably digitally added during the playback). This is important since otherwise, if the sub-titles are for example displayed normally (and thus appear to be at the depth of the screen or of the front glass of the monitor), this can ruin the 3d illusion since in that case the subtitles would appear to be behind any objects which are displayed in 3d as protruding in front of the screen, while at the same time seeming to cover parts of these object behind the letters, thus creating a clear discrepancy. Another possible variation is that preferably monitors can be designed to enable viewing with polarized glasses without giving up resolution or having to use double the normal amount of pixels compared to a normal monitor—preferably by using preferably fast switching between polarized states of the same media, such as for example a filter in front of the monitor which can change its polarization for example electronically. This means that preferably the two parts of the image are preferably switched quickly preferably many times per second in synchronization with the switching of the polarization of the filter, and preferably this is done together with a high refresh rate which is preferably at least twice faster than in a normal monitor, which can for example be accomplished easily for example in the new SED monitors or in OLED monitors, since each element there can emit light independently of the others, this enabling a almost unlimited refresh rate, and preferably this is combined preferably automatically with higher brightness in this mode in order to compensate for the light loss due to the polarization filter and the polarized glasses which the viewers wear. Another possible variation is that the user can also change for example the color of the text that shows for example on taskbar items, so that for example the user can choose black instead of the normal white, which is easier on the eye (preferably this is made available for example as one of the menu options for example when right-clicking on the taskbar). Another possible variation is that for example a stereo view web camera (preferably with at least 2 lenses—right &amp; left) or pair of cameras (or more than 2) can be used to automatically generate a 3d model of the user&#39;s body for example for avatar representation in various virtual meetings and/or for example for measuring clothes for online shopping of clothes. Of course the user can preferably use also an application which enables various fine tuning of the body features, but preferably the general image is automatically generated this way.   19. Another possible variation is that for example the user can preferably enable or disable for example Cleartype separately for various uses or contexts, so that for example the user might want to activate it for example for Word documents and/or web pages but not for some other applications, or for example activate it for everything except for example the text near the icons on the desktop, since that text already comes with a shadow and the Cleartype makes the shadow even more conspicuous, which some people may find annoying, and/or for example when Cleartype is used preferably the OS automatically corrects for example by making the shadow thinner or otherwise less conspicuous, and/or for example the user can define, preferably in general or for example for each type of application or section or context, for example not only if to use Cleartype or not but also for example to what extent to use it, so that there are for example a few possible levels of it (for example with varying degrees of making the fonts fuller or thicker). For choosing these separate settings preferably these different options are added for example to the normal menu in which the user chooses between standard fonts or Cleartype, and/or for example by right-clicking on the text of an icon on the desktop or for example in other applications the user can for example change the Cleartype setting for example only for text of desktop icons or for application of the same type, and/or the user can preferably toggle between Cleartype to standard fonts instantly without going through a menu, for example by pressing control-R or some other character, and then preferably the chosen mode becomes the default for example for other windows of the same application and/or for similar windows. Another possible variation is that the user can for example change for example the brightness and/or contrast and/or saturation and/or color and/or for example gamma correction (and/or other color and/or brightness parameters) for example separately for different elements in the user interface, which is very important since in many monitors for example the desktop looks best with a certain amount of color and/or contrast and/or saturation and/or gamma correction, but for example text windows such as for example Word documents or web pages, which contain mainly black text on a white background, typically need a lower brightness or contrast and/or lower gamma value than for example images in order to avoid eye strain, and/or for example images for example within web pages and/or in other applications need for example higher brightness and/or contrast and/or higher gamma value, and/or for example DOS or cmd windows look better with a different brightness or contrast. So preferably the user can for example set a separate brightness and/or contrast and/or saturation for example to the taskbar, separate to the desktop, separate to Word and/or web documents, separate to images, separate to dos or cmd windows, etc. (Preferably this is done for example by adding such options to the display setting menu, and/or for example by right-clicking on each such element these settings can be changed separately for it and preferably automatically also for similar elements). This means of course that the definition preferably goes logically with the appropriate element, so that for example if the user increases or reduces the size of the taskbar then preferably its color and/or brightness and/or contrast and/or gamma and/or saturation definitions automatically carry on to any new space it occupies. The implementation itself of such different settings for different elements can be done for example by the display card driver or by improved drivers of display cards which can add such parameters separately to different parts or areas or pixels of the screen and/or for example by passing all the display through an intermediate underlying layer (for example in the OS or in the display card&#39;s driver) that adds the appropriate correction for each element, for example by choosing automatically for each pixel or each area of pixels (for example rectangles, etc), a different color or color correction which approximates the effects of the desired logical parameters (this can be for example the same underlying layer that is used in vista for the vector graphics rendering of everything and which can be used for example also for the resolution Independent User Interface), and/or for example by improved hardware and/or firmware in the monitor itself which enables receiving different instructions for different pixels or for different areas on the screen (preferably after the underlying layer has translated the logical areas into actual physical areas) and/or for example by the OS changing directly some of the relevant elements to fit the requested parameters, such as for example the bottom task bar. Another possible variation is that for example the browser itself preferably adds the desired gamma correction automatically to the images that it embeds within the displayed web page, preferably while keeping the gamma correction of the text areas lower, however this can be easily done for example by the OS itself since the OS can easily identify text areas separately from image areas (since writing text is usually based on calling the relevant OS services). This is much better than the prior art, in which the user can change such settings only once for everything (or for example there a separate setting available only for Video overlay), because normally there is no single definition of these parameters that is good for all of these categories, the shared settings of the prior art means necessarily that the user has to compromise on many elements and thus views them in a sub-optimal way. In terms of productivity this seem much more important than for example using Cleartype or a normal font, since full strong black letters with a background that does not blind the user can lead to much more productivity than grey letters and a background that is too bright and thus blinds the user. In fact, it actually helps getting much more out of Cleartype fonts, because being able to set the parameters of text separately in an optimal way (for example with lower brightness and lower gamma value) enables seeing the fonts as solid black eventhough in reality the Cleartype uses various shades to fill the gaps in the contours of the fonts. For example when browsing on the Internet there is typically a mixing of images and text on most web pages, so these different settings can enable the user to see both the text and the images at optimal levels. Another possible variation is that for example when there is a different setting for video overlay, preferably at least by default until the user changes it, the saturation and/or brightens and/or contrast and/or gamma level etc, of the video overly controls are preferably automatically applied also for example also to photographs or web images, since typically there should be no difference if the images are stationary or moving. This can for example help the user make the most even of old monitors in which there is less flexibility to change such parameters when changed globally for the entire screen, and help the user achieve even better results on better monitors, thus being able to reach the optimum on each category without the normal necessary trade-off. Another possible variation is that for example the word processor and/or for example the browser preferably allow the user to choose for example the color of their normal white background to become for example different less dazzling shades of white, for example from a set of pre-selected options and/or for example by creating additional options by clicking anywhere on a 2-dimensional color map of the type used for example in various painting programs. In the browser this means that preferably whenever the browser displays a web page which has a white background or has a background which was defined in a color sufficiently close to the color that the user chose to represent white, the white parts of the page are preferably automatically converted to the chosen shade that the user has chosen. Another possible variation is that similarly fonts that appear grey for example beyond a certain threshold are automatically converted to black by the browser and/or the word processor (in this case there is no need for the user to choose the desired shade of black since clearly the blacker the font the easier it is for the eyes to see). Another possible variation is that web fonts that are too thin and appear grayish (not all thin fonts do) are automatically converted by the browser into larger fonts or into a more appropriate font type which thus becomes automatically easier to read and/or automatically converted to boldface. Another possible variation of the implementation is that for example whenever the user opens for example a sufficiently large word processor window or full window or for example a web page which contains mainly text on a white background, the OS or for example the screen driver (or for example the application itself—for example Word or the browser, or some other application) preferably automatically lowers the brightness and/or lowers the gamma value (and/or whenever the user is viewing a sufficiently large image the opposite is automatically done)—even if it is done for the entire screen (However this is preferably done, as explained above, in combination with letting the user choose the separate parameters for each of these modes, and/or for example choosing as default for images, at least initially, the same parameters which the user specified for video overlay). Preferably the change is done together with corresponding automatic correction for example in the task bar so that it preferably remains approximately the same (for example by automatically switching to brighter colors to compensate for the general darkening for example when the Word window covers most of the screen), and thus the user can have a very good approximation of the optimal experience without having to change the brightness manually for example when switching between work on Word to other activities.   20. Another problem is that for example in Windows Vista the OS can automatically decide to disable various features according to the hardware support available, such as for example the AERO glass transparency or for example the flip-3D or the animations of windows growing out of the taskbar squares or shrinking back into them without giving the user an indication about what features have been disabled or a direct choice about it, which can be very annoying. So preferably this is improved so that the OS reports to the user automatically what features have been limited or disabled and preferably also allows the user, preferably form a central convenient menu (preferably in the same window that displays the disabled features) preferably to enable again any such features, even if it causes a cost in performance. For example, at least the transparency and/or for example the animation of growing or shrinking windows can be done quite efficiently even on display cards that don&#39;t support it directly by hardware, as can be proven for example by games like Roadrash, which show amazing fast 3d graphics even on very old systems—for example even on a Celeron 400 MHz without any special display card. In addition, preferably the user can define for example if the desired features will for example work a little slower than in a fully hardware supported system or for example will be done at the same speed as in hardware supported system, for example at the expense of slowing down other applications for a preferably very short period during the displaying of the animation or other special effect (preferably except for example time critical applications if such applications are running in the user&#39;s computer) or for example of automatically reducing the resolution of the special effect. Another problem is the lack of consistency in these animations of growing and/or shrinking windows, since for example in Vista build 5270 when clicking on icons on the desktop (such as for example cmd) the windows appear to grow out of an arbitrary point on the desktop instead of from the position of the icon—so preferably the animation is improved so that when activated from the icon on the desktop it starts in this case from the position of the icon. Another problem is that when windows for example shrink into the taskbar the small window actually disappears when it is relatively small but still not close enough to the relevant desktop item. So preferably this is improved so that the smaller windows keeps showing consistently until is has completely merged with the relevant item on the taskbar. Another problem is that when moving in Vista (build 5270) between full-size windows to part-size windows there is no gradual animated transfer, but an instant abrupt jump between the 2 states, like in Windows 98 and XP, which creates a lack of consistency with the smooth animation of growing or shrinking windows when the window is minimized or expended from the minimized state. So preferably this is changed, so that a preferably smooth animation is automatically displayed also when moving from the part-size state to the full-size window and/or vice versa, but preferably the user can also choose for example from a menu if to enable for example this additional animation or not and/or similarly for other animation affects and/or other special effects. Another possible variation is that preferably the user can also for example determine the speed and/or length of each animation (for example by changing some general parameter or parameters that refer to all or most such animations or for example setting this for specific types of animations, since for example when opening the power saving window from the screen saver window in Windows Vista the animation for opening this small window takes too long and so can be annoying after a while, and similarly for example the animation in which the Search window in Word 2000 appears or disappears in Windows Vista (for example in build 5728 &amp; 5744) is very slow and therefore can become very annoying if the user cannot speed it up. (The speed of this animation in office 2007 is OK). In order to change these parameters preferably the user can for example access some control panel that deals with the animations and/or for example the user can preferably click with the right mouse button on the window that was animated and for example choose from a menu an option that allows him/her to change the speed of the animation of that window and preferably also choose for example if the new parameters will apply only to this type of window (for example the search dialogue box in Word 2000) or also to other similar windows. However, preferably the OS preferably automatically adjusts the speed preferably in all applications to the same reasonable minimum speed to that preferably opening or closing a menu or window preferably never takes more than a certain amount of time including the animation (for 2 seconds or less or 1 second or less). Another problem is that in for example in Windows Vista when the user activates the flip-3d all the windows become automatically minimized and the desktop becomes darker, and also the user can exit the flip-3d only by clicking on one of the windows in the flip-3d or by pressing Esc, which is inconsistent with other application. So preferably this is improved so that the desktop remains with the normal colors and preferably if the flip-3d is activated while one or more windows are in view preferably they are not minimized automatically (i.e. the 3d deck of windows can appear on the background of other currently open windows and not necessarily on the background of the desktop itself), and also preferably the user can exit the flip-3d also for example by clicking anywhere on the desktop and/or on the taskbar and/or by clicking on any other item on the desktop or on the taskbar or for example by clicking on the “show desktop” icon, and/or even for example by clicking again on the icon which activates the flip-3d. After this has been filed in a previous version of this application this Microsoft indeed added to Vista build 5308 the ability to click on anything items outside the Flip-3d in order to go out of it, but the user is returned to the original Window in which he/she was before activating the Flip-3d, regardless of where the user clicks now, which is very inconsistent and confusing. In the above variation the intention was of course that clicking on anything else while the Flip-3d is open preferably closes the flip-3d but indeed brings the user to where he/she clicked (for example another item from the taskbar, an icon on the desktop, the Start button, the desktop, etc,) and not back to the previous window the user was in. Another problem with flip-3d is that if there are too many open windows (for example a few dozen) then the flip 3d side shows as if there are fewer windows than the real number (apparently it shows only 10), which can be confusing to the user, and also they can be very dense sideways with no ability to see any details on the side of the windows. So preferably this is improved so that the user can preferably easily define the sideways spread of the flip 3d (for example by defining the minimum and/or maximum sideways shift and/or the vertical shift between each two adjacent windows and/or by determining the total size that the flip-3d set of windows will occupy sideways and/or for example defining the angle or angles of the window decks, for example the 3d depth angle, and/or for example defining the depth of the spread, which means for example also determining how smaller each farther window will get according to perspective), and/or preferably the correct number of windows is shown, unless for example the size had already increased to the full width of the screen, and/or for example if the size of the set reaches the full width of the screen then for example preferably only then the sideways gaps between the windows are automatically decreased. Another possible variation is that the user can for example determine how many windows will show at each layer of the 3d deck, so that for example the user can preferably request for example to see at each layer for example 2 or 3 or 4 windows which are apparently stacked at the same 3-d layer side by side, instead of seeing only one Window at each layer. Another problem with flip-3d is that for example windows that are smaller then other windows (for example cmd windows) appear smaller on the 3d deck of windows, which can be confusing since it distorts the 3d perspective. So preferably this is improved so that preferably, at least as one of the choices, the user can choose a mode in which all the windows in the 3d deck appears of the same original size (preferably regardless or their size and regardless if they are full windows or partial windows), and thus get smaller consistently only according to their depth in the 3d deck (but preferably this is the default). Similarly, preferably the size of the preview windows (for example on the taskbar) is preferably equal and not smaller if the window is smaller, since again making it smaller according to the size of the window this is more distracting than helpful. In addition, in the prior art (for example Vista beta builds 5270 and 5308) this is clearly inconsistent since for example the taskbar preview window looks taller than full-windows, such as for example Word, eventhough the taskbar window is never full-screen. Another possible variation is that for example a grouped item can appear in the flip 3d as a single “card” which is preferably for example divided internally into preview windows which can be clicked to go to them and/or for example a separate “flip-3d” can be generated for each group of items of the same application or type, for example if they are a grouped item and/or for example even if they are ungrouped (for example all the open browser windows in one flip-3d deck, all the open Word documents in another flip-3d deck, etc.). Another problem is that in Windows Vista (build 5270) although the user can change the color of the taskbar, not all colors are really available, since the user for example cannot change the taskbar to appear the same level of blue as the typical blue taskbar of Windows XP. So this is preferably improved for example by any of the above solutions, such as for example letting the user change independently the color and/or brightness and/or contrast and/or saturation of any section or element on the screen as described above. Another problem in this Vista version is that the user can only change together the color of the taskbar and the color of the top head line of each window. So preferably this is changed so that the user can change each of them (for example color, brightness contrast and/or saturation) independently, as is implied again also by the above solution. Another possible variation is that for example movie player applications and/or image viewing application can for example find automatically the best saturation for example by identifying elements for which the correct saturation is known—such as for example water, the sky, green plants and human faces, and in case of video, preferably this value is averaged over time as the movie progresses and thus becomes more reliable (assuming that the saturation does not change in the middle, unless for example there is strong evidence from similar later elements where the correct level is clear, that the saturation level has indeed changed). Another possible variation is that for example the gamma value is automatically corrected, for example by checking which gamma level adds most details (preferably measured as variation) in black areas, and preferably, again, the gamma value is calculated over time and thus is preferably calculated as an average. Another possible variation is for example that the automatic gamma correction is applied only to the black areas, thus not affecting the rest of the image. Another problem in this build is that when a full-size window is opened the color of the taskbar becomes automatically again the default black and returns to the user-chosen color only after the window is minimized or changed to part-size. So this is preferably improved so that the taskbar color does not change according to the size of any windows. Another problem is that various windows are non-expandable to full-size eventhough many times the window is not big enough to show easily the information it contains, such as for example the window that shows the list of startup programs or for example the window of the task manager. So preferably this is improved so that the OS automatically enables the user for example to enlarge preferably any window to full size even if it does not originally contain such an option, and/or for example the OS automatically allows the user to search for any string within such windows (including for example application windows, messages, etc. and/or for example any area that the user marks on the screen) or for example print its content or for example save it to a file and/or for example use cut &amp; paste (this is preferably done by automatically reading the text in any desired location on the screen and/or even automatically applying OCR for example if the text is in graphics). In addition, preferably the OS automatically allows the user also to print and/or save the contents of any window even if it was not designed for this, and/or copy for example text from the typically blue header of the window itself (which in the prior art cannot be accessed like this). Another problem is that for example even in normal windows, which are designed in advance to be enlarged or reduced or converted to full size, when not in full size typically the user can enlarge or reduce them only by dragging the bottom right corner. So preferably this in improved so that preferably for example also the left bottom corner and/or for example any other corner can also be used for reducing or enlarging the window. This way, preferably for example the top header line of the window is preferably still user for moving the window, but dragging one of its two corners is preferably user for enlarging or reducing the window. Another possible variation is that for example the lists of programs and/or application that are shown in the task manager are preferably improved to include also the full path from which they were loaded and preferably also a link or other info which shows for example what program or process activated each of the existing programs or processes (i.e. for example what applications launched them and when and/or for example what applications installed them and when, and preferably services or processes that are an original part of the OS are marked separately—for example with a different color, or for example displayed as a separate sub-group) and preferably also when is the first time they showed up on the task manager (for example 3 hours ago during the current Windows session, or even beyond sessions—for example a certain process entered the task manager for the first time 3 days ago, etc) and/or for example what they do (for example based on type definitions of drivers or of services or of applications or for example based on automatic analysis of their activities). Another possible variation is that the user can preferably for example request the task manager and/or for example the startup list and/or the Start menu and/or for example in programs such as Windows Defender or similar programs to sort the processes and/or applications for example according to how long ago they were installed or for example when they became first active, and/or for example the user can for example request for example the OS or for example the task manager or for example the security system to display automatically for example all the programs or services or processes that were added within a certain time frame (for example to the task manager and/or to the startup list and/or the Start menu)—for example all those that were added for example within the last few days or other desired period or for example all these that were added from a certain date until now or for example within a certain range of dates and/or times, and this display also preferably includes as described above preferably also information such as for example what application (preferably including its drive letter and path) installed them and preferably also what they do, based for example on automatic analysis of their behavior and/or for example on required definitions of types of activities for installed programs or drivers. Another possible variation is that preferably the user can search for specific programs or processes for example within the list of programs or processes for example within the task manager or for example with the Startup list or for example within the list of Add/Remove programs—preferably based on immediate results as the user types characters—for example like in the desktop search. Another possible variation is that if the user for example sees some new behavior of existing applications, such as for example the internet dialer automatically wanting to connect on its own or other programs changing their behavior the user can preferably for example right click on the application and then for example the OS or task manager or security system preferably shows the user preferably any changes in configuration who can be casing the new behavior and/or preferably who activates the program example if another application is now activating it. Another possible variation is that for example the task manager or for example the spyware scanner preferably connect to one or more preferably Online preferably secure databases which have information such as for example dates, version, file size and/or fingerprints (such as for example CRC, MD5 or other cheksums) of system files and/or at least most common software applications, so that preferably it can preferably instantly alert the user for example if an application which is currently running in the taskbar is suddenly found to be for example with a suspicious size or fingerprint even if it is not a known spyware, which can be used for example as an additional precaution in addition no normally preferably requesting authorization from to user for changes for example in executables files and especially system files, as described in other applications by the preset inventor. Another possible variation is that when the task manager displays the sorted list of processes with the percent of CPU time taken by each of them, preferably—at least if the percent of CPU time taken by System Idle or other global system category is beyond a certain threshold—preferably the Task manager automatically displays more detailed information about the relevant system process or drivers, so that for example if a specific driver suddenly starts to take up unusual system resources the user can know exactly which driver it is. Another possible variation is that for example when displaying preview windows of files for example in directories for example when the user works with the Windows explorer, preferably files that are video clips or movies are preferably automatically displayed in the preview image for example not as a still image but as a moving image, for example by starting to run the video automatically only within preview images which are currently in view. In this case preferably these videos are for example automatically stopped when the preview image grows out of view and automatically restarted when they go back into view (for example as the user scrolls through the displayed directory contents) and/or for example the are run in a loop for example only within the first 1-2 minutes (or any other duration), and/or for example they are reset and start to run from the beginning again every time the preview window was outside of the visible user&#39;s view and then returns again into the visible user&#39;s view. Another problem with Windows Vista (build 5270) is that the when the mouse hovers over items on the taskbar it takes about 2 seconds till the first preview window shows up and only then when the user moves to the next item the next preview window shows up instantly, so preferably this is improved so that even the first preview window (or windows, since as explained elsewhere in this application preferably multiple preview windows or all of them show up at the same time) shows up preferably instantly without this delay (and/or for example the user can preferably easily set this delay for example between 0 to a certain amount of seconds). Another problem is that for example in Windows Vista if the user moves the mouse too fast over taskbar items the preview window does not show at all. So preferably this is improved so that the preview windows are preferably prepared in advance and preferably almost no time is needed to display them, so that preferably they can show preferably even at the highest speed which the user can move the mouse for example over the taskbar or over the tab handles line for example in the browser (of course this problem does not exist if for example all the preview windows show up automatically at the same time for example when the mouse is anywhere over the taskbar or for example tab handles line for example in the browser). Another problem is that for example when an application contains more than one window—for example Winamp—the preview window shown near the taskbar item shows only the Winamp itself even if for example it is currently playing a Video file. So preferably this is improved so that in this case preferably the OS for example automatically identifies the most relevant or most informative Window (for example based on various heuristics—for example that a window that displays a video is more informative than a still or relatively still window), and/or for example a convention is defined which allows application that have multiple windows to define the window that should be chosen for preview, and/or for example in this case the OS can show more than one preview window over the same taskbar item—for example one above the other (and similar solutions can preferably be used for the Flip-3d and/or for the alt-tab with preview windows). Another possible variation is that for example computer games are improved so that for example the game can automatically assess the performance of the user (for example according to his/her scores and/or according to the time it takes him/her to reach a certain goal or goals) and can then for example automatically recommend to the user when it&#39;s time to move on to the next level. Another problem for example in the Chess game that ships with Vista (for example in build 5728) is that the user has first to click on a figure in order to see its possible moves (shown by marking the possible squares the figure can move to in blue), and then again click on the desired destination square, which is both cumbersome and counter-intuitive. So preferably this is improved so that preferably the possible moves of each figure are shown based on hover, and preferably the user can also drag the figure with the mouse to the desired destination instead of clicking on the destination (preferably the user can user either of these options in order to move the figure), thus giving the user a feeling more similar to the natural movement when playing chess in the real world. Another possible variation is that preferably the game has not only Undo for moves but also Redo (since sometimes the user might for example try again to see what went wrong or for example the user might press by mistake ̂Z too many times and therefore might want to go back forward again). Another problem is that for example popular Online multi-user games/simulations such as for example Second Life or similar systems suffer from the absurdity that they imitate also various limitations form real life which do not need to exist in such simulations, such as for example limited resources, so that for example the same users compete for limited amounts of money or for example limited amounts of real estate. So preferably this is improved so that in such simulations preferably there are preferably unlimited resources, such as for example unlimited amounts of money and/or for example unlimited available real estate which preferably users can obtain preferably with not much effort, which can be integrated in the virtual world for example by increasing the absolute amount of resources available for example preferably without limitations as needed to accommodate for all the users&#39; needs, and/or for example by combining a unified simulation in which multiple users interact with each other in the same virtual world or worlds together with showing alternate views of the same virtual world to different users, so that for example at least some types of actions or interactions between users continue to work for example like they do today for example in simulations like Second Life or similar virtual worlds or even for example various simulations of war games in virtual worlds, but at the same time preferably at least some types of things are shown differently to each user, so that for example multiple users can each have the illusion that for example they have a bigger house and/or for example bigger garden and/or for example more beautiful landscape and/or for example more money than other users in the same virtual world, while other user are preferably shown the illusions that they are the ones that have for example a bigger house or more beautiful landscape or more money than other players, etc., preferably while still maintaining a sufficiently coherent level of interaction between various users, so that preferably they can still have an illusion of participating for example in the same virtual world where there appear to be some interaction between them and/or competition over resources with other users, while at the same time as explained above preferably multiples user&#39;s can be shown the illusion that they have faired or succeeded better than others preferably without disturbing the ability of the system to offer the same illusion to multiple users in a way that would be contradictory in the real world but can be maintained in the virtual world simulation. This way users can still enjoy a game where there is seemingly at least some competition with others and a sense of being able to gain compared to others, while in reality the simulation is preferably able to give many more users the illusion that they are the ones who are winning, thus preferably using much better the ability to giver everyone unlimited resources and unlimited affluence in the virtual worlds compared to would can be done in real life. Another possible variation is for example to create a preferably multi-user online virtual world simulation in which for example users have or can develop magical abilities with the ability for example to do almost anything, preferably as long as they follow certain rules, such as for example not using their powers in a way that might hurt other users or animals or plants. This can be for example a simulation of a world such as described for example in Harry Potter books or similar books about magical worlds, except that preferably there are much less dark problems and limitations of free will and in fact the users are preferably encouraged to use their powers more creatively to help the world, such as for example solving poverty problems, ending wars, stopping pollution, saving the rainforests, etc. Such themes can be used of course also for example in a series of improved books or movies about such magical worlds, and/or for example in comedies or parodies about them, so that for example the same way that the Austin Powers series of movies was a parody on illogical things in James Bond movies, similarly there can be for example a book or movie or series of books and/or movies with a parody for example on absurd or illogical or unreasonable things for example in the world described in the Harry Potter books (or for example in the Lord of the Ring books), such as for example the poverty of the Weasly family just because their father is a government clerk while forgetting that since they are magicians they could have unlimited affluence nonetheless, or the fact that magic students they have to go through tedious studies in school like in the normal world, while in a real world of magic it should be possible to gain all or at least most or much of the needed knowledge magically for example by an instant magic which gives them the knowledge instead of having to go to school for years, or, as mentioned above, the fact that they apparently don&#39;t to anything to help the real world, while in reality in such a world the population with magic abilities could user their powers to create a much better world for everyone, such as for example by ending poverty, ending wars, ending pollution, saving the rainforests, magically increasing the intelligence and/or morality and/or level of spiritual understanding of other people, etc. So preferably, as explained above, in the improved books or movies or simulated virtual worlds preferably magicians or people who develop magical abilities preferably can and do at least some of the above described things. This preferably enables achieving much more of the real potential of such books and/or movies and/or simulated virtual worlds.   21. Another preferable improvement is that when the user searches for files on the computer preferably the “find files” window allows him/her to enter also more than one file name at the same time (for example separated by commas or one below the other, etc.), since if the user wants to search for more than one file this is better than having to search consecutively and it is also more efficient since this way all the requested files can be searched for during the same disk access.   22. Another possible variation is that preferably the installation disk (for example CD or DVD or for example through fast network connection) of the OS (for example in the new version of Windows) contains also one or more typical usable disk images, so that the system can be instantly installed from the most appropriate image, and then the system preferably automatically determines the actual computer&#39;s configuration and simply corrects and/or adds appropriate device drivers and/or makes other necessary adjustments, as if the system was already installed on that computer and the hardware was later changed. This can save a lot of time on the installation process, so that most of the time will be focused only on correcting the configuration.   23. Another problem is that, for example in Tablet PC&#39;s and/or similar devices and/or other devices that accept direct input by handwriting, when the user enters text in handwriting, it is problematic to use scrolling since the user would have the quite unnatural feeling that for example written text to the left of the current position of the pen is automatically slipping away to the left (or to the right, if the writing is from right to left). This means that if the user for example enters text by handwriting in a search box (for example when searching with the Internet browser in Google) and there is not enough room for the full search string, then there is a problem how to accommodate the additional text. This can be solved for example by letting the user continue his/her writing even beyond the edge of the input box, and then preferably the Operating System and/or for example the browser preferably automatically knows from the continuity of the written text (and/or from the continuity in time) that this is the continuation of the same text, and therefore interprets it correctly as if it is still in the input box even if its spills out for example to the right and/or to the bottom or up, and/or even the user for example continues immediate to enter text for example on a second line below the input box (preferably unless there is another input box there). Another possible variation is that if the user runs out of space in the input box, the System and/or the browser and/or other relevant application automatically extends the box for example to the right (or other relevant direction). This can be done for example by automatically extending the box for example to the right in a new layer that partially covers for example whatever is to the right of the input box so that the user has more space (for example this layer is indicated by a shadow effect as if it is a few millimeters above the screen), and/or for example the extended part and/or the handwriting on it are automatically made at least partially transparent so that whatever is below it can still be seen, and/or for example what is below the extended part and/or below the handwriting is made temporarily faded (for example gray), and/or for example whatever is to the right of the input box (however, preferably only at the vertical position of the input box) is also automatically shifted to the right (this means that things at the right edges of the screen can automatically scroll away and temporarily disappear at the right of the screen if needed, and/or the system uses this scrolling only if there is sufficient free room in the needed direction and uses one of the other options if there isn&#39;t sufficient room for this), and/or for example the area where the user is writing can automatically be zoomed in (however this preferably automatic zoom preferably does not effect the user&#39;s hand writing itself, so that the handwriting preferably remains at the same size and position). Another possible variation is that at least the part of the handwriting that spills out of the input box is visible only when the user hovers or positions the pen and/or cursor and/or mouse near it. Similarly, if the user for example is entering text by handwriting in some open text window (for example a word processor or notepad) and his/her handwriting exceeds the edge of the window, preferably the System automatically recognizes (for example by the continuity of the hand writing and/or of the temporal sequence) that this belongs to the same text and thus the system keeps the focus in the current application even if the user for example spills some letters on another nearby window of another application. Another possible variation that can increase the natural feeling for example when reading large files or digital books in tablet PCs (or for example in devices dedicate to reading digital books) is that the user can for example move the page (for example up or down or sideways) for example by dragging his finger or fingers on it in the desired direction (which means that preferably the screen can identify that this is the user&#39;s finger instead of the pen for example by the size of contact or for example by the electronic resistance, and can then respond accordingly), and/or the user can for example cause pages to flip over for example by touching with his finger a corner or edge of the displayed page or for example some relevant icon there. Of course various combinations of the above and other variation can also be used. Another preferable variation is to supply the user with an electronic pen which can preferably write on normal paper and preferably at the same time both writes with visible ink on the paper and transmits the writing sequence to the computer, so that preferably the user can write normally while also obtaining an automatic copy on the computer (which preferably immediately becomes characters through automatic recognition). This can be done for example by using a double tip, so that one part senses the movements and the other actually writes on the paper, or for example use some electronic eye which views the ink sequence as it is created on the paper and transmits that into the computer. This is also more convenient since the user can much more easily write this way when he/she sees normally the output on the paper as if it is normal writing. Another preferable variation for example in tablet PC&#39;s and/or for example in digital book readers and/or for example in programs such as for example Winamp or other software media players and/or for example in other gadgets for playing songs or films, preferably the software and/or the device is able to measure automatically preferably not only which songs or films or books (or other media) are more or less liked by the user, but preferably also for example which parts or sections in them are for example the best and/or which parts are less good or for example problematic. This can be very useful for helping improve for example those books or films or songs and/or for being able to write better ones the next time. This can be done for example by automatically noting if there are any sections which the user for example likes to hear or read or view again and again and/or for example the device or software asks the users explicitly which sections they most like and/or for example in digital books noting automatically for example which sections the user marks and/or adds comments to, and then preferably anonymous statistics are sent automatically for example over the internet for example the next time that the user connects to download for example additional songs or films or books. Another possible variation is that for example in such devices and/or software for playing for example songs or films preferably the player can automatically adjust the sound level not to exceed a certain desired limit and/or not to be too low below a certain limit. This can be done for example by automatically adjusting the level when the limit is reached or exceeded, and/or for example the software or gadget can preferably run ahead quickly in advance over the song or film and determine the maximums and minimums, however that would be much less efficient, and also the local adjustment is even better since preferably a separate optimization is done for each section. Another possible variation is that for example song-playing software, such as for example Winamp, can automatically update their songs list, for example by adding automatically all the relevant files that are found automatically during the updating of the local search index (for example by taking it from the results of the Google desktop search or the Microsoft desktop search), or for example by remembering the list of directories from which the playlist was generated and checking automatically these specific directories (for example every few minutes or any other convenient interval) and if additional relevant files (for example of the relevant file types) have been added then the software preferably adds them automatically to the playlist, and preferably the playlist is for example automatically sorted with an index, for example alphabetically, so when adding songs preferably the index is automatically kept updated at the relevant order. However this is preferably done on a playlist that contains one or more full directories, and the user can preferably also define additional partial playlists, which are not automatically expanded like this. Another possible variation is that for example in Winamp (or in similar programs that can work with a playlist) when the user for example uses “J” (jump) or other convention to pick a list of songs by typing a string of letters, preferably the user does not have to chose a single result but can for example mark multiple results and then for example press play or Enter or otherwise activate them, and then preferably the player marks them automatically as a sub-list within the normal play list and preferably starts playing the marked songs preferably one after the other (preferably jumping each time to the next marked song) preferably until the marked sub-list is finished (and/or for example the user can also request various combinations, such as for example playing songs from the marks sub-list interspersed with playing songs from the normal lists, with or without random order).   24. Another problem is that for example in Windows XP when the user opens for example multiple browser or word processor windows, typically they automatically become like an internal division within one window on the taskbar, so that the browser or word processor appears in the taskbar only once and the other open windows of that application are listed within it (although at least alt-tab properly jumps between the windows as if they were normally marked as multiple instances of the application on the task bar). Since this can be inconvenient or confusing for example for users who are used to all the windows of the same application appearing in the task bar, preferably the OS allows the user to activate a command which can for example automatically toggle between this mode to the mode where each window appears separately on the task bar. Another possible variation is that the user can also for example activate a command which can toggle between such grouped items (and/or separate items on the task bar) to tabs representation and/or vice versa (so that for example all the windows of the same browser become a single united window with all their tabs together, and preferably the user can for example activate this as a global command that affects for example all the open applications, or for example affects only the windows of the specific application which the user clicked upon). Another possible variation is that the user can for example group or ungroup the windows of a specific application for example by clicking on the grouped icon or on one of the icons of the application on the task bar (for example if they are not grouped) and then for example clicking the right mouse button and for example choosing from a menu, and preferably this remains the default for the specific application (for example the Opera browser) even after the user closes it and reopens it, until the user changes it again (This is better than the prior art, in which the user can choose group or ungroup only globally—i.e. either for all the applications or for none). This can be done for example by just simulating graphically the other representations (even though typically tabs are actually threads and other open windows of the same application are typically actual processes (preferably with some indication that for example the converted new tab is not really a normal tab or a converted separate window is actually a tab), and/or for example also in this case for example each tab which is converted into a separate window (or item in a group) is actually closed and a new tab automatically opened for it instead, and/or for example when the vice versa conversion is used each such tab is closed and an actual window is opened instead (for example of the same file or Internet URL, etc.). Another possible variation is that if for example a browser window becomes crowded with too many tabs the user can for example click with the mouse on a certain point on the tabs handle line and then for example choose as one of the menu options splitting the browser window into two or more separate windows so that for example all the tabs to the left of the clicked position remain in the original browser window and all the tabs to the right of the clicked position automatically move into the a new browser window, and/or for example the user can activate a command which also chooses automatically the split-up position, which can be done for example by choosing automatically the middle position or for example choosing automatically for the new window all the tabs that belong to the domain in the tabs most recently visited by the user or for example all the tabs most recently visited by the user, or other criteria. Another possible variation is that the user can for example activate a command which causes all the most recently visited tab handles to become automatically larger and/or otherwise more conspicuous and/or for example this is the default. Another possible variation is that one of the options available to the user (for example when right-clicking on the tab handles areas, for example in addition to “close all tabs” or “close all but active tabs”) is for example to close for example all the less recently accessed tabs or for example all the least accessed tabs or for example all the tabs that have already been visited, or some other criterion or criteria which automatically select only some of the tabs for closing. Another possible variation is that preferably the user can for example minimize a tab for example by clicking again on its tab handle while it is open (similarly to clicking again on an item on the taskbar) or for example by clicking for example on a minimize icon (for example in the shape of a minus sign, for example below or near the X in the tab handle or for example on the corner, for example the top right corner, of the tab itself), thus enabling the user to jump back to the last tab without having to click on ctrl-tab. Another possible variation is that the user can for example activate a command which causes all the tabs to be ordered automatically for example so that each time a tab is closed or minimized the user automatically jumps to the next tab (for example to the right or to the left) even if that is not the order of last activation. Another possible variation is that for opening new tabs and/or new windows the user can preferably tell the browser for example if to start new tabs or new windows in general for example with the user-define default home page or for example with the current page from which the new tab or window is being opened, and/or for example there are at least two separate commands for opening new tabs (or windows) wherein one type creates a copy of the current window or tab and the other uses the user defined default start page (preferably the default is creating a new tab with the default home page, since that is typically the most useful option). Another possible variation is that the user can for example define more than one default home page and can preferably also specify if each of them will be for example in a tab in the same window or for example in a new window and preferably also specify for example which of them will be the active tab (for example the user might specify that the default home page set is for example 3 open tabs, for example one a Google web search page, one a stock market page, and one a Google news search page, for example, and for example specify that the Google web search page will be the default active tab, and in the case of multiple default home pages preferably this active tab will also be the default page which is opened when the user opens a new tab, and/or for example the user can specify that separately). Preferably this can be either specified for example at the preferences menu where the user defines the home page, and/or for example the user can open the relevant tabs in the desired order and with the desired active tab and then for example press some control or for example click or some icon or for example choose some menu option which sets this as the default set of home pages. Another possible variation is that the user can for example mark this set of tabs or for example specific individual tabs for example from the currently set of open tabs to be always opened together with the last automatically saved session of tabs, so that even if some of them were closed for example in the last session, when the browser reopens preferably these tabs will be opened automatically in addition to the automatic reopening of the tabs of the last session (but preferably these tabs are not added twice, i.e., if they already exist in the last saved session). Another problem is that for example in the Opera browser the new “Quick Dial” feature which enables the user to chose from a set of default home pages (typically the portals which the user uses most often) whenever the user opens a new tab (by mouse or by Control followed by the serial number of the choice) works only after the user opens the new tab, and pressing control with a number without first opening a new tab will make the change over the currently forefront tab. So preferably this is improved so that for example a different control followed by a number (such as for example Alt followed by the number, or some other control) can automatically open the chosen default page in a new tab without having to first open a new tab—which can be much faster. Another possible variation is that the user can for example toggle between opening the chosen page number over the current tab or in a new tab for example by changing some option menu or clicking on some icon, and/or for example by default the browser automatically uses smarter heuristics so that for example by default the browser opens this in the current tab if the forefront tab is an empty tab with the Quick Dial menu, and into a new tab if the current tab is a normal active tab, since typically that would be the most reasonable behavior for a user. Preferably when the user closes all the tabs in the browser these default tabs are preferably left open, or the user is for example asked for example if he/she wants to close all the tabs or all but the default start tabs or all but the active tab or all but the default tabs and the active tab, or all but the active tab. Another problem with browsers that can automatically save the last session and reopen automatically with the tabs that were opened the last time (for example Opera, and Firefox with the Save Sessions extension) is that they behave unreliably on reopen when multiple windows are closed, so that for example if more than a few seconds pass between the closing of the multiple windows, on reopen only the last window will be restored. So preferably this is increased to a considerably longer thresholds—for example a minute or a few minutes (since if a user closed another window for example more than a minute ago and then closes the current window that it is much more likely that he/she intended the previous window to remain closed, whereas a few seconds don&#39;t mean anything since for example the user might close the current window that he/she is working on and not even notice immediately that there are additional open windows for example of the browser), and preferably the user can change this time from the default. Another possible variation is that, since indeed the user might not notice that there was another open window of the browser for example even after a longer time and only then closes it too and later reopens the browser (which prevent the automatic restore of the current window), preferably the browser (or other application) also takes into account for example how much time the user spent on each window and/or how many tabs were open in that window when it was closed, and can assume for example that it is more likely that the user will want to reopen a window that had much more tabs and/or the window on which he/she was spending most of the time in the last session. Anyway, this problem is reduced by the ability to undo also the closing of windows (which is described further below this application) and/or saving automatically also a list of previous sessions (including open tabs and/or windows), as described further below. Preferably the browser saves automatically also the history of each window separately, since the user might for example want to restore windows that were open more or less at the same time into a different state in the individual history of different windows (this doesn&#39;t take much space since the browser can simply save for example just the links, and if used recently the relevant pages will probably still be in the user&#39;s local cache. If for example multiple histories are saved and certain links repeat themselves, for example a pointer to links that are already in the browser history can be used for example instead of the full link). Another possible variation is that preferably even if the user for example tells the browser after reopening it for example to start from the home page instead of from the last session of open tabs, preferably the user can undo this and then preferably the browser automatically restores the tabs of the last session, which is preferably done by saving automatically the list of open tabs for each session and keeping these lists even if the user request by mistake or not by mistake to start a new session (preferably at least for a certain time period and/or as long as there is enough room, and preferably at least in the form of the list of url addresses, so that even if the temporary cache was erased in the meantime the browser can simply get them again from the web). Another problem is that for example in the Opera browser if the browser was unable to reach a url and is closed, when reopened the tabs with such url become blank tabs without the address. Firefox with the save sessions extension does remember the url but only if it had sufficient time to try reaching the page and displays an error message page. So preferably this is improved so that the url address is automatically saved even if the browser was closed before it displayed an error message for such urls, so that when reopened the user can try again to reach those urls. Another problem is that for example sometimes one (or more) tabs is causing a problem and when the browser reopens the save-sessions automatically restores also the problematic tab or tabs. Although for example in Firefox the save-sessions extension offers the user in such a case to ignore the saved session, preferably this is improved so that the save-session feature can also offer the user in such cases for example to automatically remove only the problematic tab or tabs so that the browser can be reopened for example with all the other tabs intact and the problematic tab does not show or for example its handle exists but when the user clicks on it for example only the url is shown with a message that it has caused the problem the last time. So preferably if the browser has crashed and/or for example continues to crash at least 1 more time on the next re-open, preferably the browser can automatically reopen the next time automatically without the tab or tabs that were responsible for the crash (for example as default and/or with request for user confirmation for disabling the problematic tab or tabs, preferably by displaying at least the url and/or title of each such problematic tab), so that preferably it reopens the next time without that tab or tabs or for example shows their url and/or title but displays for example, instead of displaying their content, a message that the tab has been disabled due to causing a crash the last time (and/or for example this message enables the user for example to try again anyway to reload the problematic tab, for example by pressing a link or button in the displayed message and/or for example by pressing the normal reload button). Preferably the above behavior is displayed for example both in case the user himself/herself reopens the browser and in case the browser is configured to reopen automatically after a crash. Preferably the browser also indicates automatically the cause of the crash and/or estimated cause, and preferably the browser knows which tab or tabs caused the crash for example by a fault protection trap for example in the browser&#39;s software which is for example activated whenever there is a problem in some thread, so that preferably the browser can document the problem and the identity of the relevant tab before closing, and/or for example each tab or thread preferably automatically keeps some log, so that the crash and the casing tab or tabs can be identified automatically when the browser examines the logs the next time. Another possible variation is that preferably for example the above described trap can be used for example in order to prevent the browser form crashing in all cases or at least in some of the cases where a tab encounters a run time error, so that preferably the browser can automatically close or disable the problematic tab or tabs and/or request user confirmation before trying to reopen it, as described above, preferably without the browser itself crashing, so that the other tabs remain open. Another possible variation is that similar methods are preferably used to prevent cases where for example a run time error in one of the open windows of the browser causes other open windows of the browser to close—so that preferably in this case there is at least one process of the browser which catches run time errors which could cause other open windows to crash, and/or for example when disabling tabs and/or warning the user on reopen preferably both the relevant tab(s) and/or relevant window(s) are indicated. Another possible variation is that automatic “sessions” are preferably similarly automatically saved preferably all the time or at short intervals for example by the OS also for open windows or squares on the taskbar (preferably by saving only the minimal required relevant information), so that preferably after a crash or even after a normal reboot the windows that were open the previous time can preferably be re-opened automatically (again, preferably without the window that caused the crash if for example a specific program caused a crash the last time, or with request for user authorization for re-opening also the problematic problem). Although Microsoft Vista enables such automatic reopening of windows after a reboot when a reboot is required when installing some program or driver, the above solution is much wider and means that this is preferably available after any boot at least as an option so that the user is preferably asked automatically at the end of each reboot if to reopen automatically the windows that were open the last time. Another possible variation is that the user can for example mark one or more squares on the taskbar (for example by opening a menu by clicking the right mouse button over the square) so that they become applications that are automatically opened on the taskbar after each boot (such as for example a cmd window, a Word window an Opera browser window, etc). Another problem is that if there are multiple tabs open (for example 10 or 20 or 30 or more, and especially if there are more) and the user closes the browser and then reopens it, it can take quite some time till all the tabs are restored and during this time the user cannot use these tabs or even a new tab productively since the multiple downloads of all the tabs are slowing everything down. So preferably this is improved so that upon reload (i.e. when reopening the browser) the browser preferably gives higher priority in download and/or in cache allocation to the tabs which the user most recently viewed before closing the browser the last time (preferably for this the browser can use for example the heuristics that the tabs at the right edge are typically the tabs most recently viewed, but more preferably the browser preferably saves automatically for each tab for example a tag with the last time the user viewed it or clicked on it or for example saves a value which represents the priority level for each tab or for example saved some ordering information between the tabs, and this is preferably saved automatically for example every few seconds, so that it can work also after a crash), and/or for example if the user after reopening the browser clicks on a certain tab handle (or for example also if he/she merely hovers over it) preferably the browser preferably immediately gives download priority to that tab, and if for example the user opens a new tab preferably that tabs gets the highest priory, so that preferably each time the tab or tabs that are at the focus of the user preferably have higher priority and preferably work preferably at the highest possible speed and the other tabs preferably continue to download at the background with lower priority and/or lower speed until the reload is complete. This is preferably done with gradual change in priority after the tab that is in the user&#39;s immediate focus, so that for example the tab in focus gets preferably higher or much higher priority than the other tabs, and for example the last viewed 3-4 tabs preferably get medium priority and so are preferably downloaded for example immediately after the tab in focus has been downloaded (preferably unless for example it is delayed because of some problem with the specific server) and the other tabs get lowest priority, so they are preferably loaded mainly after the front tabs and the few last viewed tabs have been loaded (preferably unless there is some specific problem that causes delay in the higher priority tabs). Preferably similar priorities are automatically used if the user for example presses on a key which causes automatic reloading of all the tabs. Another possible variation is that tab priority can be based for example also on hover, so that for example tabs which the user hovers over their handle preferably automatically get higher priority while the user is hovering over them, especially for example if this is associated also with the automatic preview windows. Another possible variation is that if the user for example presses by mistake the Reload-all control, preferably the user can abort this preferably instantly, for example by pressing for example Esc or some other control or clinking on some icon, and for this preferably the browser keeps a copy of the last version of each tab and does not erase it at least until the reload data of that page is complete, and so if the user cancels the reload preferably the browser preferably immediately stops the reloading and reverts to the old version of each tab, for example even for tabs for which the reload has already completed, or for example only for tabs in which the reloading has not completed yet. Similarly if for example the user tries to quickly close opens tabs when the browser is being reopened, preferably the browser gives highest priority to the action of for example clicking on the X to close a tab and so preferably closes it instantly when the user click on the X, and/or for example the user can mark a group of tabs (for example by pulling with the mouse some lever above or below them to cover their range or for example clicking with the right mouse button on one of them and then dragging some mark for example to the left or to the right to cover additional tabs) and then close them instantly for example with a single click. Another possible variation is the for example the web browser allows the user to activate track changes for reloading a web page, so that preferably when reloading the page for which track changes is activated the browser preferably displays the changes between the previous state of the page to the state after the reload (for example manual reload or for example with automatic reload based on the change or on a periodic interval), which can be very useful for example if the user reloads for example a page of world stock indexes such as for example http://in.finance.yahoo.com/intlindices and wants to see more clearly the changes between the last two states. Another possible variation is that preferably the user can also use for example a special back icon or control for going back to previous state or states of the reloaded page, which is enabled for example by the browser automatically saving also the previous states of the page being reload, for example until a certain amount of pages or for example until a certain amount of time backwards. Another possible variation is that for example during these steps backwards the user can for example also request for example from the browser to display the track changes between any two states of the pages. Another problem is that sometimes a user clicks on a link or even a sequence of links without opening them in a new tab and only then realizes that it would have been more convenient to open them in a new tab, and then if the user wants to do this the user has to go back till the original page and start reopening the links on which he/she clicked into a new tab or tabs, or remain with the current tab and search again for the original page in a new tab. So preferably this is improved so that when going back to a previous page preferably the user has also an option (for example through a menu when right-clicking with the mouse on the “Go-back” icon or for example through a separate icon) of opening the “Go-back” in a separate tab (in which case preferably a new tab is created and the history of the current tab is preferably automatically copied also to the new tab and then the new tab is automatically reverted preferably one step backwards), and/or for example the user preferably has an option of duplicating one or more tabs (for example by right-clicking with the mouse on the tab handle and choosing from a menu and/or for example by pressing some control key while in the tab), in which case preferably simply a new tab (or tabs) is created and the history of the current tab (or tabs) is preferably automatically copied to it, so that the user can then for example go pack to a previous page in either the copy or the original tab. Another possible variation is that preferably the browser also enables to open for example preferably any button into a new tab or new window, and the user can preferably choose this for example from a menu by right clicking on it with the mouse, similar to normal links, and so preferably for example this can be applied to preferably any search box with the typical “search button” by right clicking on the search button and choosing for example to open it in a new tab. Another possible variation is that after the user has for example gone back one or more steps for example within the same tab, the user can also request for example to go forward into a separate tab even when the user previously was there in the same tab. Another problem is that for example in Opera if the user enters a url address in one or more tabs and the browser is closed before the browser had time to actually access this address or addresses, on reopen these not-yet-visited tabs disappear. So preferably this is improved so that the browser automatically remembers also tabs with url addresses which have not been visited yet, and preferably these are also reopened automatically when reopening the browser and then preferably the browser trys to reach these addresses. Another possible variation is that for example a session with the current open tabs, preferably including the history of each of them, can be saved for example in a standard format that can allow easy porting between different browsers, for example by using a simple html page (or for example XML format), and if for example the browser allows marking a set of links and opening them at once or for example clicking on an icon or menu option that opens automatically all the links of a page (preferably by default into multiple tabs) then the effect of reconstructing the session can be easily achieved. Another problem for example with Firefox is that extensions are limited to the current version so when a new version of the browser comes out, extensions that have not been updated for the new version don&#39;t work. So Preferably this is improved so that for example as long as commands have not been deleted in the new version of the browser or its scripting language, preferably the browser can automatically update the extension to work on it ignore the specified version. Another possible variation is that when the browser shows the list of extensions preferably the list indicates also near each extension the url from which it was installed. Another possible variation is that whenever the user installs an extension preferably a copy of it (for example the XPI file in case of Firefox extensions) is also automatically downloaded (for example to the user&#39;s default download directory), so that for example if there are later problems the user has automatically the source of the extension available on his/her computer even if the extension is for example later removed from the url where he/she downloaded it, or for example the browser can automatically export to a file the source code of any installed extension upon request for example by extracting it from the installed extension. Another possible variation is that the browser enables the user to easily sent the list of extensions to someone else by email, for example by choosing a menu option that says for example “Send extensions”, for example in a way similar to “send page” in Netscape, except that what is sent is the list of extension (and preferably, as explained above, each entry on the list indicates also the url form which the extension was downloaded), and so the receiver can for example know exactly where to get any of the extensions that he/she wants, or for example the browser allows the receiver to automatically get any of the extensions which he/she for example marks in the received list, preferably from the indicated urls. (however the list of extensions is preferably sent in a simple html or even more preferably simple text format, in order to protect against attempt to deceive the receiver with a phony list that actually does something else, so preferably the user can see the list in plain text (for example for each extension the name of the extension and the url from which it was downloaded and preferably also a short description of what it does—preferably generated for example automatically by the sending browser for example by automatically extracting it from the original page at the time the original user installs it) and preferably when the user opens such a text file with the receiving browser preferably the receiving browser preferably automatically generates from it a list of sent extensions in which the user can mark what he/she wants and send the browser to get it (In addition preferably the browser automatically requests the user&#39;s authorization even for marked extensions if they are not from one of the already authorized sites, such as for example the Mozilla site, since the user might mark extensions without noticing the url). Another possible variation is that, like for example in the “Noscript” extension, the user can for example define a white list of domains or even specific urls in which to enable for example Javasrcipt and/or active-x or other active content, but preferably in sites which the user has not whitelisted yet preferably the user is explicitly prompted for active content, since in the “Noscript” solution in such sites the browser simply user a small mark at the bottom to indicate that Javascript has been blocked but the user might not even notice it and the user simply sees an empty or improper page. Another possible variation is that for example various extensions or plug-ins that speed up internet surfing by pre-loading links that the user has not yet clicked on (and/or for example the browser enforces this automatically) automatically disable any active content on the pre-fetched links and can enable it for example only if and when the user actually chooses to open the link. This is very important since otherwise the user can really be exposed to unnecessary risks since the pre-fetching of links would expose the user to active content or possible exploits on links which the user would not normally click on. (The risk is reduced if the pre-fetching for example only saves a cache of links without any attempt to interpret them before the user actually clicks on the link, but for safety reasons it is better even to avoid caching the code of pages that contain exploits, so another possible variation is that for example sections of the page that contain active content (for example Javascript or active-x subroutines) are automatically not saved during the re-fetch and instead the pre-fetcher preferably saves there only for example a special link or indication which is used for getting the actual missing part of or parts the page only if the user decides to actually click on the link). Another possible variation is that preferably for example the TCP/IP protocol (and/or other protocols that might exist or that might replace it in the future) are preferably improved so that for example at least the text parts in web pages are automatically compressed by the http server (for example by zip or other standard compression format)(this is less relevant for images since typically their format is already compressed more or less close to the possible optimum) preferably before sending to the browsers or other client programs that request them (actually if this becomes the standard then preferably the pages are saved on the server already in their compressed format so that the server does not have to compress them again on the fly each time they are requested, which is much more efficient, even if for example a local cache for recently compressed requested pages is used or the server), and preferably the browser (or other client program) automatically uncompresses the data automatically on the fly as it is being received. However, since browsers preferably can start displaying a page even before it is fully received, preferably the compression format a preferably modified format that enables decompressing parts of the compressed file as they arrive without having to wait for the entire file for starting the decompression. This is preferably done for example by including for example at the beginning of the file all the information needed to decompress what comes next, even in independent sub-units, or even more preferably for example by using a format which contains for example independent units of data, each with its own decompression information (for example in a way similar to base frames in streaming video), so that for example preferably the browser can decompress parts even if the beginning of the file arrives later than other packets. Preferably if for example CRC (or similar data) is used for checking integrity of the compressed data, preferably this data is kept independently for each sub-section, so that there is no need to wait for example for the end of the file to verify its integrity. In other words, the automatic pre-compression of pages preferably does not reduce the flexibility or ability of browsers to display information even before it is completely received. Since text data can typically be compresses by even 70-90%, compressing for example the html or xml parts of the page (preferably including of course the control commands for example within the ‘&lt;’ ‘&gt;’ marks), can significantly boost speed. Of course, packets can be for example instead compressed on the packet level, but that is less efficient since it would mean compressing also for example images or video data which cannot be efficiently further compressed anyway, and also wasting time on compression on the fly while it can be done more efficiently in advance based on knowledge of the text parts which can be most efficiently compressed. However, for compatibility issues for example with older browser who might not support this, preferably the http server keeps preferably for each page for example both a normal copy and compressed copy and preferably the new browsers that support this preferably tell the server through an appropriate code during identification that they support compressed text format of pages and then the server knows it can send them automatically the pre-compressed pages instead of normal pages. By using preferably the pre-compression of the saved files on the server in advance (so that they do not need to be compressed again on the fly each time they are requested), as explained above, and since usually the decompression is considerably faster than compression, and since typically bandwidth bottleneck problems are much more common than the user&#39;s CPU reaching its limit, the small extra time needed for the decompression by the user&#39;s browser and/or for example ftp client (or other client programs) can typically be much less than the transfer time saved. In addition, preferably the text or html editors on the server and/or similar client editors on the user&#39;s PC can preferably support the compressed files in a transparent way, so that for example html and/or xml files and/or other supported types are preferably automatically compressed into the special compressed format when saved and automatically decompressed when displayed for editing. Another possible variation is that, since it is very rare today that users request browsers to ignore images or use text-based browsers without images, and since in the normal http protocol the browser first requests the page and then requests its images according to the image-embedding code it finds in the page, preferably the protocol is improved so that the browser (and/or other internet applications) can preferably also give the server for example a url and request the server to send already in advance also all the related images and/or for example other embedded files and not only the page itself, thus saving on the unnecessary traffic of requesting for example each additional image separately, and preferably all of these are sent together in a single packet or at least combined into a small number of packets. Preferably by using for example an additional code for this when requesting the page, preferably backward compatibility is saved for older browsers or other applications that don&#39;t support this and continue to request pages normally. Another possible variation is the protocol is improved so that preferably the server can automatically send in advance all the information about embedded images and/or other data (preferably together with information about the size of each) at the beginning of the communication preferably before sending the page itself, so that the browser (and/or other application) can request them or decide if to request each of them or all of them in one bunch in advance even before parsing the page itself (this is preferably done by saving this data in advance on the server together with the page, for example in some automatically generated tag preferably at the beginning of the page or for example in a linked file preferably at the beginning of the page, so that the server preferably does not have to do this on the fly each time the page is requested. Preferably this tag is for example automatically generated improved html editors, and/or for example automatically added to the file for example by the http server if it is not there, for example automatically for example the first time that the server accesses the file). If this variation is used then preferably this also is preferably done by requesting the url with a special code, however if it is done for example by an automatically generated tag at the beginning of the page this is not necessary since the tag can be designed so that older applications which don&#39;t know what to do with it will simply ignore it. In addition, preferably in the above variations the page is preferably sent as a single large packet or at least as small a number of packets as possible, thus even further reducing the load on the routers (for example In Internet 2 the advantages of this will be even more automatic since the packets there can be considerably bigger anyway, and so saving unnecessary back and forth communication for fetching the embedded images and/or other files and thus enabling sending the whole page together with the embedded parts preferably in one large packet or a few large packets will be even more natural). Another possible variation is that preferably ftp clients and/or the ftp protocol are improved so that preferably the user can also use the ftp client to change the access rights to files and/or directories, for example by being able to execute the chmod command or a similar command which changes access rights through the ftp access, for example in Unix servers or Windows, or other operating systems. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. In addition, preferably the user can for example define or change which controls will do various things such as for example save a bookmark or open a new tab or open a new window, since for example in Firefox ̂D saves a bookmark and ̂T opens a new tab and ̂N opens a new window, whereas for example in Opera ̂T saves a bookmark and ̂N opens a new tab, so users who switch for example between browsers might feel uncomfortable or confused with a different set of such controls. So preferably the browser allows the user to open for example a table that shows the current control characters and what they do and the user can for example change the controls for each action and preferably can for example define even multiple controls that can do the same thing, such as for example both ̂D and ̂T for saving a bookmark. Another possible variation is that the user can for example copy a group of or the entire set of tab handles from one open browser windows and reopen it in a another window of the same browser or even of a different browser (which can be done for example if the OS and/or some other application keeps track of the open tabs or at least of their url addresses or if this multi-tabs-copy and/or paste function is available in both browsers) Another possible variation is to enable for example also tabs for example in word processing applications and/or other applications, such as for example other Office programs (these tabs can be for example threads of the same window or for example normal additional windows of the same application, except that they have an interface like tabs in a browser). Another possible variation is that for example if the tabs become too many (and thus too small), the browser (or other application) can for example automatically and/or by user request enlarge the line of tab handles for example to two or more lines instead of one (for example like the taskbar can be increased to more than one line). Another possible variation is that for example the other windows of the same group can be shown for example in another task bar, for example at the top of the screen (but preferably visible only when the user is viewing at least one of the windows of the group), and/or for example within the typically blue top of the main open window of the group and/or for example at least the user can toggle into this mode. Another possible variation is for example to improve the AERO interface for example in Windows Vista, so that for example when the user clicks on the icon of the group for example in the lower taskbar (for example Word or an Internet browser), preferably instead of a list of names in lines below each other, the group can for example automatically expand for example to preferably small images of the relevant Windows, and preferably the size of the images is preferably automatically determined by the number of windows, so that if for example there are 4 windows then each preferably occupies more or less a quarter of the screen or for example a little less, and preferably for example by clicking on any of these preview images the user preferably immediately jumps into it. AERO apparently only shows a small image of each icon on the bottom task bar when the mouse is over it, and I am not aware of treating grouped windows in the way described above. In addition, according to the AERO demo video available from Microsoft at http://channel9.msdn.com/Showpost.aspx?postid=114694 (new_kam_vedbrat_aero — 2005.wmv), published Sep. 13, 2005, apparently when the mouse is on top of an icon in the bottom task bar the image shown has the same width as the icon. So this could be of course a problem if the icon is smaller due to having too many icons on the task bar. So preferably this is improved so that, at least if the icon is below a certain minimal width, preferably the image is automatically made wider than the icon—preferably with a minimal size which is preferably defined by default by the system, and preferably this definition can also be changed by the user. Another possible variation is that if the user automatically changes the desired size of these preview windows—for example by resizing such a window, preferably the other preview windows will also become automatically of the new size defined by the user, for example until he/she resizes it again, and/or at least as long as it is above some minimum size defined by the system. For example, the user might even enlarge the preview window for example to the size of a full screen or almost full screen (of course preferably without covering the other items in the task bar—like normal windows that are at full size), and/or the system might even for example choose this as default, which means that preferably by simply moving the mouse button over an item (for example an item on the taskbar or a tab handle in the browser) the item (i.e. the relevant tab or window) preferably instantly springs into view, which enables seeing much more easily than for example a small window of a few centimeters, and then when the mouse moves over the next item, the next item for example springs into full view instead. Another possible variation is that the user can achieve the same effect for example by hovering with the mouse over the task bar or for example over the area of the tab handles in the browser and rolling the mouse wheel, and, preferably this works in a circular way, so that after reaching the most extreme tab at the right the next tab becomes the most extreme left tab, and vice versa when reaching the extreme tab at the left in when going in the other direction. This is still much faster than the prior art, where the user would have to click on each item to view its contents. Another possible variation is that for example as the user moves the mouse vertically up or down over the list of names in grouped items (wherein this list appears for example only after clicking on the group item, as is done in current XP, and/or for example even after merely putting the mouse over the group icon), preferably a preview image of the window which the mouse is currently over its name preferably appears for example sideways near the item and/or near the list. Another possible variation is that for example when the user moves the mouse over the items for example in the taskbar (or items in grouped windows, or tabs) preferably the preview image springs into view for more than one of them (for example also for the previous and the next item or for example for even more items, for example automatically according to the current size of the preview window, so that preferably the images fill the space for example sideways for example for at least one such line of images), or for all the items (so that for example hovering with the mouse over the tab handles area preferably fills preferably the entire tab area with preview windows of preferably all the tabs, so that the user can simply move the mouse over one of them and click on it). Preferably if for example preview windows of all the tabs are preferably automatically displayed for example preferably as soon as the user hovers with the mouse over the tab handles line, preferably the size of these windows is automatically reduced so that all will fit in one screen or for example if there is still no room, preferably automatic scrolling is used (for example when the user hovers near the bottom of the display) so that the user does not have to waste time moving the mouse to a lever on the side to pull it up or down, or for example when the user hovers with the mouse for example at or near the bottom of the display the view can preferably instantly switch to the remaining items, which is faster than scrolling. Preferably the user can choose the number of preview windows that will be displayed at the same time and/or how many rows of preview windows will be displayed and/or for example if he/she wishes that the preview windows of all the tabs (or windows, etc.) will all show up at the same time for example when the mouse is over the bottom task bar or for example over the browser&#39;s top tab handles bar, etc. Preferably if a tab contains for example streaming video, the streaming video continues also in the relevant preview window of the tab. Another possible variation is that for example when the user moves the mouse over these items they increase in size gradually around the current item, for example like the virtual magnifying glass features in maps, so that for example the squares on the taskbar or the squares representing the tabs (tab handles) become preferably gradually larger with more details (thus preferably containing more text in order to help the user to quickly identify it), so that the current item (the tab handle or the square in the taskbar over which the mouse is directly) is the largest, and/or the preview images similarly grow in size accordingly (preferably the change in size as the mouse moves is also gradual in order to keep the smoothness, or for example the change is in discrete jumps), or for example only one tab handle or square on the taskbar becomes bigger, preferably instantly when the mouse hovers over it. The increase in size can be for example vertical or horizontal or both, thus for example compressing automatically other tabs squares or taskbar items on the side for example or for example partially covering some of them or for example the expanded tab handle or handles or taskbar item become semi-transparent so that the tab handles or taskbar items behind it are still visible at least partially, or for example the extended tab handle or handles or taskbar items show for example in a second raw, preferably with some visual line connecting them to the original item or tab handle (and are preferably of course clickable also by themselves) or for example only a bubble or other structure with preferably only the text appears near the tab or taskbar item, but preferably instantly, and this bubble for example appears only for the current tab or taskbar item or for example also for one or more items on each side of it. If more than one preview window or bubble show up at the same time then preferably there is for example an automatic line or other visual connection which connects between the preview window or bubble to the item and/or preferably the user can also click directly on the bubble in order to enter the item, similarly to the ability to click on the preview window. Another possible variation is that for example the preview windows are for example a few centimeters in size, but for example if the user puts the mouse over the preview window itself (for example immediately or after a short time which the user can preferably change) it grows into a larger size even if the user does not click on it (again, similar to the virtual magnifying glass) and/or for example if the user leaves the mouse for more than a small time (for example 1 or 2 second or more) over a certain section of the preview window and/or moves the mouse slowly over a certain section in the preview window for example as if trying to read it, the system can for example automatically show that section in enlarged form (for example like in a magnifying glass area or for example by opening an enlarged version of that section in a larger additional preview window which is focused on that section or for example the entire preview window is further increased automatically with that section preferably remaining at the same current position of the mouse) (This automatic enlarging of the preview windows and/or of parts of them is preferably done for example by the system saving in advance each preview window in more than one size or for example saving a larger size and reducing it on a need basis or even for example using some feature in the graphic display card which can for example do the reduction or enlarging automatically, and this automatic enlarging can preferably be applied for example to any type of preview window for example in the various described variations where preview windows are used). Another possible variation is that if for example the user clicks on the preview window for example after having kept or slowly moved the mouse over a certain section of it (for example text or image), the actual page is opened with that section of text or image at the center of the screen or more preferably for example at the current mouse position, so that the mouse is preferably still found pointing at the same section when the user jumps to the actual page, and/or for example the mouse is automatically moved to the position of that section when the user jumps to actual page (however, that is less preferable since making the mouse position suddenly jump without the user actually moving the mouse can be confusing and/or annoying). Another possible variation is that the user can also for example move the preview window or windows into a certain position, so that for example the preview window or windows will show in the specific user-selected area. Another possible variation is that preferably the scroll wheel that exists in many mice between the two buttons preferably can also be tilted at least slightly to the right or to the left, which can preferably be used for scrolling sideways (for example in too wide web pages or for example spreadsheets where a horizontal scroll bar needs to be used). This is preferably accompanied by some additional freedom for this sideways movement, for example by making the wheel a little thinner than in normal mice and/or the gap around it a little wider, so that for example it can be tilted 1-3 mm to each side. The tilting itself can preferably be sensed for example by a potentiometer which is changed when wheel is tilted or for example mechanical sensors or optical sensors or induction sensors or electromagnetic sensors. However, it turns out that Microsoft already tried out mice which enabled similar titling of the wheel, but users found it inconvenient to use apparently because a large force was needed to tilt the wheel and because such a small movement of the wheel means a very low resolution of movement compared to the rotation of the mouse wheel for up-down movement. Therefore, a better variation is that preferably the mouse wheel enables a higher resolution also for sideways movement, preferably similar to the resolution of the up-own movement. This can be done for example by using a mouse wheel which is preferably sensitive to a caressing sideways movement of the finger, so that preferably the wheel itself does not tilt sideways, but preferably a caressing movement of the finger to the right or to the left of on wheel can preferably be sensed for example by galvanic resistance sensors or by any other electronic means known in the art. And since the mouse wheel typically contains sideways grooves and protrusions, when the user moves the finger over the sideways protrusions it can feel similar to as if there were many tiny sideway rings around the external ring of the mouse wheel, which are rotated sideways when the user moves the finger right or left on the mouse wheel. Another possible variation is to add for sideways movement an additional mouse wheel for example on the left edge of the mouse where the thumb typically is, so that preferably the second wheel rotates horizontally around a vertical hinge (compared to the vertical rotation of the normal mouse wheel around a horizontal hinge). Another possible variation is to add for this purpose for example such a horizontally rotating wheel for example at the front edge at the bottom of the keyboard preferably near the left edge (or for example a vertically rotating wheel which rotates to the right and to the left for example near the left Alt key), where typically the thumb of the left hand is, so that the user can use the left thumb for sideways scrolling. Another possible variation is to use various software solutions for the sideways scrolling which can work also with normal mice, so that for example when a page in too wide and a horizontal scroll bar is automatically created, preferably the user does not have to go down with the mouse to drag the horizontal scroll bar but for example preferably clicking in any position on the page for example with the mouse preferably enables the dragging right or left. However, since for example clicking with the left mouse button might also be used for example for marking text, preferably this works automatically in an intelligent fashion, so that for example if the user wants to mark text he/she has to click near the text and preferably clicking in an open area and then dragging is preferably automatically interpreted for example by the browser as an intention to scroll sideways, or for example in order to scroll sideways the user clicks on some keyboard key and preferably keeps it pressed while dragging with the mouse right or left. Another possible variation is that for example the mouse is improved to enable preferably more fingers (preferably all five fingers) to interact with it naturally—for example by adding a notch or button for each finger so that preferably all the fingers naturally rest each over its respective button, or for example the mouse is made into a concave shape like for example the bottom half of a glove. Another possible variation is that for example the title and/or url and/or for example file name is also displayed for example automatically, for example above the top edge of the preview window, preferably in normal text size that can be easily read, and/or even without the preview window and/or for example the user can toggle between various types of display (for example only text, only preview windows, or both) (Although in current XP and Windows 98 for example the url or file name is displayed in a small elongated square after some time if the mouse button is kept for some time over the item in the task bar, this is very different since it is so slow that it is quicker to simply click on the item in order to see what it is, so preferably this switched very fast for example as soon as the mouse is on the item—preferably at the same speed the preview images appear for example in the AERO interface). Although for example in Vista beta build 5270 there are titles which appear above the preview windows of the taskbar items, the title appears only after the user hovers with the mouse over the preview window for about 2 seconds, which is much less efficient than the above solution, in which both the preview window and the title or additional textual description preferably both appear instantaneously. Another possible variation is that for example when the user puts the mouse over an icon on the desktop or on the list of quick launch icons the system (preferably immediately, without the 1-2 second delay) displays additional info about it (preferably for example the file name and path) and/or the user can for example preferably easily control the length of this time threshold. Another possible variation is that when the user hovers with the mouse over an icon on the typically bottom task bar preferably the information that is preferably instantly displayed (without the 1-2 second delay), with or without preview windows and/or example at the top of the preview windows, preferably includes also the path and file name. Another possible variation is that for example whenever a message window is displayed on the screen the user can see for example the path and file name of the program or process that generated the message, for example by hovering with the mouse for example over the header of the message window or for example by right clicking on it and getting a menu, and/or for example the user can choose an options that for example makes the OS (or for example the security system or some other application) display this information automatically for example somewhere on the message window. Another possible variation is that preferably this information and/or for example preview windows are also displayed automatically for example for items that show up in the list of active programs and/or task manager that shows for example when the user presses Control-Alt-Delete. Another possible variation is that for example if the preview window is too small (for example only a few centimeters) and/or contains for example only or mainly text without images, the system can for example automatically decide to display for example only the title and/or first few lines and/or first few images in the windows, since otherwise, for example if these windows or tabs are for example Word documents or for example a list of Google search results, the user might not be able to distinguish between them if he/she is shown only a small preview window which only shows small text (in other words, preferably the system automatically analyses each window or tab, preferably already before the mouse is over it, and decides what type of preview would be most informative—for example a small image of the entire window if it is sufficiently graphic and/or if it is sufficiently different in general visually from the other or neighboring windows or tabs, and for example a few lines of text, preferably of the current position on the text, if it is for example a Word document with little or no graphics at the current page and/or for example the list of search keywords if it is a Google results page (preferably the browser uses various heuristics for finding that this is a search results page and for finding the search keywords, for example by finding that it is a search page for example according the url (for example Google, etc.) and according the typical regular repeating structure in which search results are typically displayed and/or finding the search words for example as parameters in the url and/or in the search box)(this text of the for example relevant Word lines or for example Google search keywords can be displayed for example in the preview window itself or for example above it, for example between the file name and the preview window)), and/or for example the user can define some preferences about what part or parts of the window to show in the preview. Another possible variation is that if for example there are multiple open word-processor windows and/or tabs of documents with similar names, preferably the system automatically highlights the sections that are different when displaying the file names, for example by giving these sections automatically a different color and/or showing the file names so that these different sections appear at the center. Another possible variation is that for example if some of the tabs are for example Google search results (or are for example related to the same site and/or have for example clearly something else in common—for example are Word documents or pdf files or were for example opened from each other, so that the sequence of opened tabs becomes one group, and this way for example if the user stars 3 different searches for example from 3 Google tabs, the other tabs automatically belong to the search subject from which they were opened), then for example when putting the mouse over one of these tabs (which means that the user is probably trying to find for example one of those Google search results tabs or for example Word documents or for example pdf files), preferably the system for example automatically displays for example only the preview windows of for example Google search results tabs (or windows) or for example Word tabs (or windows) or for example pdf tabs (or windows), for example next to each other in a line below the line of tab handles and/or for example automatically increases the size of the tab handles of these related tabs (for example on the same line of tabs, for example by making them simply longer and/or for example by making them protrude onwards and/or downwards for example like a 3d expanding ray of light, for example together with some shadow and/or color effects and/or animations, and/or for example in a new line of tabs below the current line). If these are for example Google search results tabs and also if for example within each such preview window what is most clearly visible is the search words as in the above variation (or for example the search words appear as text for example near the preview window, for example above it, for example between the title to the preview window), then the user can find the desired window or tab almost instantly, and then can for example preferably click on the desired preview window or on the tab handle (or taskbar square) in order to jump instantly into it (of course in any of the variations where preview windows are shown preferably clicking on the window instantly jumps into it and preferably before that preferably just hovering over it preferably further increases its size automatically, and preferably for example clicking anywhere on the active tab or window, for example between the preview windows, removes them and jumps back to the active tab or window). Another possible variation is that the user can for example manually drag or mark one or more tabs for example into a certain group, thus creating manually the groups, and/or for example even in this case preferably new tabs are by default added automatically to group of tabs from which they were opened. Another possible variation is that the user can for example type a string of letters or keywords and search automatically for example within all the open tabs of the browser (or for example in all the open windows for example of the browser and/or of another application or for example of all the open windows and the desktop) and so preferably for example all the tabs (or windows) where the searched text (and/or for example closely similar text) is found are preferably marked or and/or for example preview windows spring up for these tabs (and/or windows), for example as normal reduced size preview windows and/or preferably with the view of the area of the desired text, and then the user can preferably click on the desired preview window and preferably jump instantly into the relevant tab or window (the user can for example identify Google tabs or for example Words file tabs or for example pdf file tabs according to the first letter or symbol which is for example a typical shaped G in case of Google, which is usually visible even if the tab handles become very small). Another possible variation is that the user can for example search for text in the url (and/or in the contents of the tabs or windows), so that for example typing “Goog” or “google” will for example preferably instantly show all the preview windows of tabs (and/or windows) from Google, or for example typing microsoft will show all the tabs and/or preview windows from Microsoft, and/or if the user types for example “checkout” or “shopping cart” the preview windows of tabs or windows that currently show a shopping cart will be shown. The relevant tabs can be shown for example in an additional line of tabs below the original, and/or for example a pull-down list of only the relevant tabs is preferably instantly opened for example below the tab over which the mouse is hovering, which means that for example if there are for example 5 such tabs, the user can either click directly on one of them to jump directly into that specific tab, or (for example if they are already too small to see details and the user does not remember which of them is which) can hover with the mouse over any one of them and then immediately see a pull down list which shows for example at least one line for each of the relevant tabs of that category, and then by clicking on the line the user preferably jumps directly into the desired tab, and preferably each such line contains at the side, for example the right end, for example an X for closing that tab if the user wished to close it, and preferably the user can also for example mark with the mouse a group of tabs and then close them together at once, and/or for example the relevant tab handles on the normal tab handles line become for example preferably instantly wider and all the other (non-selected) tab handles become for example preferably thinner, so that the user can instantly pick only the relevant ones. This last option can be most relevant for example if the user searches for example in multiple google searches for example for various Altec Lansing speaker models and then for example decides that the most interesting results are about model ATP3 and then wants for example to go back and look only at the tabs that deal with this model. Another possible variation is that the user can also for example automatically close all the unselected tabs or for example automatically move them temporarily into some hidden buffer or line of tab handles which can later be retuned to (for example by going there directly or by returning to the original tab handles line or by selecting a new search within the open tabs) which don&#39;t currently clog the tab handles line, or for example this is what happens by default. Another possible variation is that for example the browser window can automatically become split for example into two windows, so that for example the current window has all the relevant tabs and all the other tabs are preferably automatically moved to the other window. Another possible variation is that the system or browser takes into account also the differentiating value of the word or words that the user typed, so that for example if the word google or microsoft appears for example in 20 out of 50 tabs but for example only in 8 of the tabs this word appears in the url or in the title of the page then preferably only the 8 most relevant tabs are shown (or for example all the 30 are shown but those in which the word is in the url or title are preferably shown for example in a more emphasized section at the top), but if for example the words “shopping cart” appear only in 3 tabs within the page itself these are shown even though it is not in the title or url. Another possible variation is that if for example there are too menu preview windows to fit on one screen, instead of adding a side bar for scrolling up or down, the browser (or other application) can for example automatically cascade the preview windows or cut each preview window so that for example only the top half or top third of the preview window is seen, and/or for example the user can for example choose the desired vertical cutting point of the preview windows (for example show the whole window, only the top half, only the top third, etc.) and/ore for example apply this even when there is sufficient room, since for example viewing only the top half of the window can actually save time since it can be less distracting and the browser preferably shows anyway the title and/or url on the top of the preview window. Another possible variation is that the user can for example mark one or more of the tabs to become more conspicuous so that he/she can instantly identify them even when there are many other tabs, so that for example clicking with the right mouse key on the tab handle enables this as one of the options, and then the marked tab handle becomes for example larger or higher or with some frame around it, or other visual mark, such as for example an arrow or other mark pointing towards it for example from above (preferably together with a readable indication of the site&#39;s name for example on a below or above the normal tab handles line), or other visual indication. Another possible variation is that if for example the browser is allowed to wrap the tab handles line into more than one line if it becomes too dense, preferably the user can define for example the maximum number of tabs allowed per line or for example the minimum width of a tab handle. Another problem is that many sites don&#39;t have a predefined icon, which makes it more difficult to distinguish between them and other tabs when the tab handles become too small, so preferably in the tabs from such domains the browser preferably automatically generates an icon for the domain to put at the left end of the tab handle. This can be done for example by using automatically the first image that appears for example on the beginning of the page if it appears in all or most of the pages from that domain (and then use it preferably for all the tabs from that domain, or for example finding the first image that does seem to repeat in most them) and for example automatically reducing that image to the appropriate size and using it as the icon at the beginning of the tab handle, or for example taking the first letter of the domain name and adding to it automatically a certain color and/or style which is preferably made different for example for each domain or category of tabs (if the domain name for example starts with “the”, the word “the” can for example be ignored, especially for example if at least one other tabs is from a domain that also starts with “the”, or for example the “T” is used). Although there is for example an extension for Firefox called HashColouredTabs which helps when the domain does not have a predefined icon, it only adds a colored square, which is much less differentiating than the above variation. Another possible variation is to use a similar mechanism also for example for items on the bottom task bar, so that for example the open windows of the same application are not grouped, but when they become too small to see details for example (for example all the windows of Word or all the windows of Firefox or all the windows of MSIE) the user can simply hover with the mouse over any one of the relevant icons on the taskbar and then see the pull up list of textual choices and/or preview windows of the relevant group and then click on the desired line or preview window). Another possible variation is that similarly for the grouped items preferably each line contains also for example an X which the user can click on to close that window (and preferably the user can for example mark with the mouse a group of the windows and then close them together at once), and preferably closing a window does not make the menu of windows disappear (which is much more convenient than the prior art in which for example in Windows XP the user has to click on the right mouse button and then chose close form a menu that opens, and in addition to that the pull-up menu disappears after each such action and the user has to click again on the group icon, which is very tedious, unless of course the user wants to close the entire group at once). Another possible variation is that for example each square on the task bar contains for example an X (or some other mark or icon), for example on the right or on the left side of it, for quick closing for the window, instead of having to right-click with the mouse, wait for the menu to appear and then choose the ‘close’ option (however, for compatibility reasons preferably this menu also continues to be supported so that the user can user either of these methods to close the window). Another problem for example in tabs is that for example in the Opera browser when the tab handles become smaller (for example already when there are around 13 tabs in the same browser window) the X at the right of the tab handles for closing the tab disappears and shows again only after the user clicks on the tab handle, which is inefficient since now the user has to click twice for closing a tab instead of only once, and also there is a problem that when the tab handles become even smaller (when there are around 30 tabs in the windows), when the X shows it fills up almost all of the space of the tab handle. (In the Firefox browser for example when the Firefox is used with the “Tab X” extension, when the tab handles become too small the X becomes partially hidden until it almost disappears altogether). So preferably this is improved so that the “X” (or other letter or icon for closing) preferably shows always, without having to click once before seeing it, and preferably the X (or other letter or icon for closing) becomes automatically smaller when the tab handles becomes smaller (however it preferably becomes only thinner and not smaller in height since reducing the height will not gain anything), preferably without parts of it becoming hidden, so that preferably it is still not more than a certain percent of the tab handle&#39;s space (such as for example 10-20% of the width of the tab handle or other reasonable limit, and/or at least until the X reaches a certain minimal size), which is no problem since users can be quite exact with the mouse movements. This is also important because for example in the Opera browser at a certain size of tab handles the X fills almost the entire area of the tab area, and so many time the user licks on the X by mistake while merely trying to click on the tab handle. Preferably a similar solution is used if for example such an “X” (or other letter or mark or icon for closing) is added for example to the squares (or similar shapes) which represent items on the taskbar (However, since the user might click on the X by mistake, preferably this is combined with the variation in which the user can for example press ̂Z or some other key in order to reopen any window if it was for example closed by mistake, as explained elsewhere is this application). Another possible variation is that for example if the user is clicking consecutively (for example at or beyond some minimum threshold speed) on the “X” for closing tabs even when not closing each time the most extreme tab on the right, preferably the browser automatically makes the X of the next tab handle jump into the same position (for example by dealing differently with the width of the tab handles to the right and to the left of the position where the user is clicking on the X and/or by changing the position of the X within the tab handle that is currently at the clicking area), so that preferably the X remains at the same position after each deletion, and then preferably for example after a second or more after the user stops closing tabs preferably the tabs handles regain the correct width. Another possible variation is that as the tab handles (or for example the squares on the taskbar) become smaller preferably the text of the tab handles (or squares on the taskbar) becomes automatically thinner (preferably without reducing the height), thus enabling the user to still see more information, however this automatic thinning is preferably limited till a certain threshold (for example text gets thinner until it becomes 70% of the original width or some other reasonable threshold, preferably changeable by the user), since becoming too thin might make it too much effort to read conveniently. Another possible variation is that similarly the original icon of the site (or the icon automatically generating by the browser, as explained elsewhere in this invention), which is typically shown at the left of the tab handle (or the icon of the application on the taskbar, at the left of the square) also become similarly automatically thinner as the tab handles (or squares of the taskbar) become smaller. Another possible variation is that preferably as more tab handles (and/or for example boxes on the task bar) are added and become more crowded preferably the borders between the tabs handles (and/or for example boxes on the task bar) preferably become automatically thinner relative to the size of the tab handles themselves and/or for example the wasted spaces on the right and on the left of the icon/text of the tab handle (or box on the task bar) preferably become automatically smaller relative to the space occupied by the icon and/or text—so as to maximize the available space for displaying the actual informative part. This means that for example when there are for example a few dozen tabs or more preferably almost all the area of the tab handle is used for displaying the icon and preferably the X for closing it is made very small for example occupying merely 10-20% or less of the tab handle space, so as not to occupy space that can be used for information, since the user can easily click also for example on an area of for example 2×2 mm, as explained also elsewhere in this application (This better use of the space by reducing the borders between the tab handles and/or using the maximum possible space within the tab handle is preferably done even when there are less tabs, but preferably the effects is brought to the maximum when there are more tabs, or for example it is brought to the maximum with any number of tabs, i.e. even when the tab handles are much bigger, for example when there are 20 tabs or less). In addition, preferably the X at least in this case does not occupy a space in a square of its own but preferably becomes for example two thin crossing lines which can preferably for example at least partially cover for example part of the right edge of the icon without hiding the area of the icon that is in the background. This is very different from the prior art, since for example in MSIE, Firefox and Opera when there are a few dozen tabs handles on the same tab handles line it becomes virtually impossible to see any information in the tab handle unless the tab lines become split into more than one line (in firefox after a certain amount of tabs an additional tabs line is automatically created and in MSIE additional tabs become available only through a pull-down menu, which is less efficient and requires extra clicking to reach the additional tabs). However, since when there are so many tab handles each handle can become much thinner than its height, this means that the icons in the tab handles are preferably also automatically made thinner instead of being truncated when the tab handle becomes thinner—in order to still display as much information as possible. Another possible variation is that if for example the width of each tab handle becomes for example less than half of its height (or some other breakpoint rules) preferably the tab handles line is automatically split into two lines—preferably for example without occupying substantially more height than the original tab line or for example occupying a line and a half or less or at least less then two lines, since if the tab handle becomes so thin the icon can be displayed also for example in just half of its height, which means that two icons can use the same space, and the tabs handles are preferably automatically distributed evenly between the available tab handle lines. Another possible variation is that if for example two or 3 tab handle lines are used instead of 1 then preferably the top menus of the browser (above and/or below the tab handles lines) are preferably automatically reduced in height (preferably in a smart way that reduces mainly unnecessary spaces and/or reduces in height for example some icons, for example like the preferable ability to reduce the ribbon for example in word 2007, as described elsewhere in this application)(and/or similarly with taskbar lines, as explained above), so that preferably the available space for displaying the web pages preferably remains more or less the same. In addition, preferably in any case when a new tab handles line is opened then preferably the tab handles are preferably automatically distributed preferably more or less evenly between the available lines, unlike for example prior art Firefox, where the previous line is still compressed and the new line is only partially utilized. Of course, various combinations of the above and other variations can also be used. Another possible variation is that for example if more than one version of the same application is open at the same time (for example Word 2003 together with Word 2007), preferably the OS for example automatically adds differentiating information to their icon at the left of their square on the taskbar (and/or for example when showing them when pressing Alt-tab), for example by adding automatically the words 2003 and 2007 respectively for example at the bottom of the icon). Another possible variation is that preferably the user can automatically convert for example any proportional fonts into fixed space fonts and/or vice versa, thus creating preferably a new additional font which preferably has the same name as the original font, preferably plus preferably an extension which preferably says if its proportional or fixed and/or if it is original or automatically converted font. This conversion is preferably done for example by automatically thinning or widening characters as needed and/or for adding or removing empty pixel columns on their sides. These additional new fonts can then preferably be used for example in the word processor and/or in other applications or for example as various OS related fonts. Another possible variation is that for example the user can request the OS to create this conversion for example automatically to all the installed fonts. Another possible variation in that the user can for example perform the conversion for example on the current fonts for example in a specific document and/or for example if the converted fonts already exist, for example instantly replace each font with the equivalent fixed font or with the equivalent proportional spacing font, and preferably this is also is one of the changes which can be previewed for example in Office 2007 before clicking and actually making the change, Another possible variation is that the “X” (or other icon) for closing windows is also added for example to the decks of Windows that show in the flip 3d and/or to the icons and/or preview windows that show when the user clicks Alt-Tab or for example to the items in the pull-down menu that can preferably show all the tabs in the browser (preferably in addition to the normal tab handles). Another possible variation is that preferably the user can define for example the smallest size that a tab handle or a square (or other shape) on the taskbar can become and/or the maximum number of squares or tab handles per line, because for example in the prior art Windows XP the OS automatically decides when to start using and additional line or lines with a scroll bar without asking the user, eventhough the user might prefer for example more smaller tabs without resorting to the scrolling between additional lines, at least until there are more tabs on the normal line (or lines) without scrolling. Another possible variation is that the user can for example use the mouse to reduce the size of the section devoted to the Start button, so that for example the Start button can become as small or as thin as the user wants, thus gaining more space for the squares on the taskbar. Another possible variation is that for example after a certain amount of squares is reached on the taskbar and/or the squares become smaller than a certain threshold, for example one or more additional lines of squares can be automatically added for example by making the square lines (for example automatically and/or as a default which the user can enable or disable) shorter in height. This is no problem since in the normal taskbar for example in Windows XP there is clearly a wasted area at the top and bottom margins of each square. In this case preferably the icons that typically show at the left of squares in the taskbar preferably become automatically shorter in height and/or for example the top and bottom margins become closer to them. (A similar variation can also be used for example with tab handle lines for example if more than one tab-handles line is needed, for example in the web browser. Another possible variation is that for example if additional taskbar lines have to be added they are for example added automatically on a need basis without resorting to scrolling between taskbar lines so that one or more lines can become invisible (and preferably the user can define the maximum number of lines that can thus be added automatically and/or if scrolling should be disabled or enabled). If for example more taskbar lines are added (or the user for example manually raises the top of the task bar) and for example the taskbar begins to cover some icons at the bottom part of the desktop then for example these icons are preferably automatically moved up if there is room or for example the entire desktop above the taskbar (for example in Windows Vista) can for example automatically become slightly compressed in height to fit the new reduced height of the desktop, preferably while keeping everything in proportions or for example just the vertical spaces between icons are automatically reduced while the icons remain at the same size, and when the taskbar becomes again shorter in height (for example because of closing open windows) then preferably this is also automatically returned to the way it was before (unless for example the user indicates that he/she wants to keep the desktop view this way even after the taskbar becomes smaller again (for example by entering some menu for this or clicking on something). Another possible variation is that for example the “&gt;&gt;” arrow at the right of the quick launch area can be on top of the dividing border that separates between this section and the central section of the taskbar, and/or similarly for example the area that enables enlarging or reducing the size of the system tray, thus increasing further the free space left for normal squares (or other shapes) on the taskbar. Another possible variation is that the user can for example define various general rules or conditions for displaying or hiding items in the system tray, for example according to certain events. Another possible variation is that preferably for example merely hovering with the mouse over the system tray can automatically cause the tray to expand, so that the user can instantly see the additional applications that are on the tray, and preferably when this happens preferably the icons that were visible in the normal minimized state of the tray preferably remain at the same positions, so that if the user for example wanted to click on one of them the expansion does not disturb him/her since he/she can still click on exactly the same spot the he/she intended before the tray automatically expanded. Another possible variation is that preferably similarly for example merely hovering with the mouse for example over the arrow at the edge of the area of the quick launch icons preferably automatically preferably instantly shows also the expanded list without having to click on the arrow and then having to wait for the rest of the list to appear. (The removal of the delay which typically occurs for example in the prior art for example in Windows XP when clicking there on the first time is preferably done for example by automatically generating the expanded list for example immediately after the boot so that when the user clicks on it no extra processing is needed for instantly displaying the list of additional icons). Another possible variation is that the user can preferably easily define for example by clicking with the right mouse button on each item on the system tray if it should be visible at all times or not—so that preferably the OS automatically adds this choice to the right-mouse menu of preferably each item in the system tray. Another possible variation is that preferably the user can preferably easily change the order or position of items on the system tray for example by dragging them with the mouse, for example in a way similar to the ability to change the position of items in the quick launch area. Similarly, there is a problem that if the user for example installs the Microsoft desktop search on Windows XP, it installs a search window which occupies a whole section in the taskbar and does not allow the user to reduce that section to less than about 5.5 centimeters, So preferably this is improved so that the user can reduce it to any size he/she wants, which is no problem since anyway automatic horizontal scrolling is used if the text is longer than the size of the search windows. (Of course, like in other places, various combinations of the above variations can also be used). Another possible variation is that preferably the square on the taskbar that represents an open DOS or cmd window preferably shows also the drive letter and the path of the open window, instead of showing for example always the letter and path “c:” as is done for example in Windows XP (and/or preferably the path is also displayed for example on the top line of the open window). Similarly, preferably the path and/or the drive letter is also preferably displayed for example in the relevant square in the taskbar for example for open word processor documents and/or other documents and/or other applications and/or for example on the top line of the open window which shows the file name, since in the prior art if the user for example opens for example in Word two similar or identical file names in two different directories, it is very difficult to know which is which. Another possible variation is that preferably the DOS or cmd window keeps more consistency with normal windows, so that for example the user can click or double click on a file name in order to run it and/or for example click on a directory name in order to go into that directory, and/or for example click on a file name with the right mouse button in order to open a menu for example like the menus that are available for example on the desktop on in the Explore window, and/or preferably the mark and/or copy and/or paste work also the same way they work in normal windows (for example by dragging the mouse with the left mouse button clicked and pressing ̂C or ̂V), without having to right-click with the mouse on the cmd window and choosing mark or paste from a menu, and similarly preferably the user can for example right click with the mouse on a file name in the CMD window also for example for deleting it or renaming it (preferably by choosing such an option in the menu that appears. (Through out the application, whenever the CMD or DOS windows are referred to, similar features can be made available also to other command-line modes, such as for example the command line shell in Linux or the new Windows Power Shell). Another possible variation is that preferably the user can also use for example marking and directly copy and paste for example also for example from the title line of web pages (which typically appears for example in Windows XP in the blue header line at the top of the tab or window). Another problem is that for example in Windows Vista if the user tries to copy files for example to a root of a drive or to delete files or various other activities within a CMD window, the OS simply refuses and says “access denied” without any further explanation. So preferably this is improved so that the UAC prompt is used in CMD windows just like other normal windows when needed, instead of just refusing. Another possible variation is that (since, as explained elsewhere in this application, preferably any or various menu options can be dragged also as an icon to the desktop), preferably the user can for example use the right-mouse menu on a cmd icon to drag the option of “Run-as Administrator” to the desktop, thus creating preferably a separate CMD icon which preferably when clicked enters the user automatically into the CMD in Administrator mode (and preferably the text of this submenu option is automatically included in the text that appears below that icon), and/or similar icons can preferably also be created for other windows or applications, so that when the user clicks on them they are automatically activated in administrator mode, thus saving the user time. Another problem is that for example in Windows XP pasting into a CMD window works much slower than for example normal paste in Windows or for example pasting into a DOS windows in Windows 98. This slowness might be useful for example in some applications which might expect the input to be slower, but this is very rare so normally this is just annoying and inefficient. So preferably this is improved so that pasting into a CMD windows is preferably done at the normal fast speed and for example if there is a specific problem with some application then preferably the user can use for example a separate command (for example other than ̂V or the normal paste command) which works in the lower paste speed (and/or preferably the user can for example set the speed itself on the low-speed command so as to be able to optimize it to the maximum that can still work OK). Another possible variation in that preferably this is accompanied for example with a sufficiently large input buffer of for example at least a few Megabytes or more so that for example the buffer can keep the patched data for applications that are slower but are able to signal when they are unable to read the input fast enough. Another possible variation is that for example when deleting a file from a DOS or CMD window it is also added automatically to the recycle bin, like when deleting a file for example through the Windows explorer, and can then preferably be undeleted for example by dragging it back from the recycle bin (for example through the Windows explorer) or for example by copying it back from there for example within the DOS or CMD window. Another problem for example in Windows XP is that for example Hebrew fonts in file names that can be seen in Hebrew for example in the Save or Open dialogue box may be displayed for example as questions marks in a cmd window. So this is preferably improved so that the fonts in the cmd windows are displayed the same way and in the explore or dialogue box. Another possible variation is that for example if the OS does not know how display some fonts it will always use at least some meaningful character set and preferably allow the user to easily change the set, but will preferably never display just question marks. Similarly, for example in Windows Vista preferably the OS enables the user also to run programs from a cmd window in elevated mode, for example by adding this as one of the options in the menu for example when right-clicking on the item with the mouse, and/or for example when double clicking or single-clinking on an item (for example with the left or the right mouse button or either of them) (for example both in cmd windows and in normal windows or on the desktop) preferably a menu appears which lets the user choose between Run normal and Run elevated. Another possible variation is that for example the user can activate programs on the desktop by clicking only once on the icon for example with the left mouse button (as is done for example with quick-launch items on the taskbar) instead of having to click twice. (In Windows Vista this is preferably combined with the above options of Run elevated, so that for example after clicking once on a desktop icon the menu which allows choosing Run normal or Run elevated shows up (preferably with normal run pre-selected, and then for example if the user clicks again on run normal or even just clicks again on the icon then preferably normal run is activated and only if the user explicitly clicks on the option of run elevated then that option is activated). Another possible variation is that for example hovering with the mouse on any item in the tab handles line opens for example a pull down list of all the open tabs (preferably for example together with the symbol or icon of the site or domain for example to the left of the text in each line), or for example the list shows all the tabs but those from the relevant category (for example from Google if the user hovers over a tab of a page from Google) show up in a top section of the list and/or more emphasized), and/or for example all the preview windows of the tabs are shown but those from the relevant category appear on the top and/or emphasized. Of course, like in the other places, various combinations of these variations can also be used. Another possible variation is that for example when the user clicks on the group icon for example with the right mouse button, one of the options (in addition to “close group”) is for example “minimize group, which minimizes all the windows of the group without minimizing other windows (which would happen if the user for example pressed the “show desktop” icon). Like with the preview windows, preferably the number of open tabs in each window is preferably indicated also in each line of the pull-up menu and/or for example in the relevant square on the task bar, for example if it is not a grouped window. Another possible variation is that for example the desktop search is modified to preferably automatically search also for example the currently open browser tabs and/or windows (currently Google desktop search and the Microsoft desktop search don&#39;t do this). In this case preferably results from open windows and/or tabs (and/or other currently open files) are preferably displayed in a separate category (since they are by definition the most recent)—for example on top of the list of results and/or for example on a separate category, and preferably these results and/or other types of results are shown together with a preview window for example next to them. The desktop search can access the browser&#39;s open tabs for example by monitoring which urls are being opened (for example though the firewall) and/or for example by becoming defined also as a browser helper or plug-in (and/or installing for example also a related browser helper or plug-in, which can for example show as a search box for example at the bottom of the browser window) and/or for example by searching the most recent cached urls in the browser&#39;s area of temporary files, and/or for example by other preferably standard communication with the browser. If the user wants to search for example only for text in the currently open tabs then this can be entered for example by typing the search string or keywords while the mouse is for example anywhere in one of the open web pages (but not in a form field), in which case preferably the browser or for example desktop search application preferably automatically identifies it as searching for text in open tabs (and/for example also other windows for example of the browser), or for example the user can type it only when the mouse hovers over or near the tab handles line or for example above it, or the user can for example type it in the special search box for example at the bottom or top of the browser window, or for example typing it anywhere on the page as explained above also automatically causes the text to jump into the relevant bottom search box (or for example if a voice recognition application is installed and running together with a microphone, the user can preferably also for example say the words, for example “google” or “shopping cart”, for example while the mouse is for example anywhere on the web page preferably outside of form fields, and then preferably the search in the open tabs is performed as explained above). If the search in the open tabs or windows is done for example as part of the desktop search and is for example displayed as a special category, preferably at the top of the search results, as explained above, then the user can for example type it in the normal search box of the desktop search. Another possible variation is that when installing the desktop search preferably it automatically indexes first the most recent files and/or directories, since most likely the user will search for more recent things, and thus the desktop search can become useful even after it has only indexed a small part of the files. Another possible variation is that for example the desktop search line contains by default the last search word or words or string which the user searched for and preferably if the user wants to change it he/she can for example move over it for example with the arrows or mouse and change or add characters and preferably if he/she starts typing something new from the start then preferably the previous search string automatically disappears. Another possible variation is that when displaying search results for example from multiple open tabs and/or windows the cursor and/or display jumps into the relevant text and then jumps again when the users jumps to the next found occurrence of the text, and when the last occurrence is found in the current tab or window then the next jump is automatically to the occurrence of the text in the next tab or window where it occurs, etc. Another possible variation is that the user can for example define the level of priority for various criteria for example for displaying the desktop search results, such as for example define how much weight to give to recency versus relevance. Another possible variation is that when the user is shown the desktop search results (for example from the Google desktop search) preferably for example he/she can drag a result to the desktop to create an icon for it. Preferably the results from the indexing of the open tabs or windows are also kept for example in the desktop database even after the tabs are closed so that if for example the user later searches for these keywords preferably the results can include also for example bookmarks or histories which contain links to the pages where these words appeared (this is better than searching for example over bookmarks to find some site which the user wants to return to, since sometimes the words that the user remembers appear not in the title or url but somewhere within the page at the URL). Another possible variation is that the user can for example tell the desktop search to index for example also the existing bookmarks and/or history lists that were already existing for example at the time the desktop search was installed, in which case preferably the desktop search can for example open all the relevant URLs (for example through the browser and/or preferably while taking advantage of the local cache of at least recently visited web pages) and index them automatically in the background. Another possible variation (for example if the user uses for example the Google desktop search) is that preferably the search application for example just sends for example to one or more of the Google databases the list of relevant urls and gets the relevant indexing preferably instantly for example from the Google databases (since these web pages are constantly indexed anyway on the web), and/or for example when the user searches for something locally or on the web the Google search application can for example search automatically also in the list of bookmarks or historically saved urls (automatic history list) if the desired keywords appear in them and then for example can display them for example in a special results category (and/or for example the desktop search and/or the browser can for example check for each search result if it already exists for example in the bookmarks and/or in the history list or lists and/or for example display those results for example with a special mark that indicates that the user already visited them). Another possible variation is that for example when the user is browsing the net and suddenly for example one or more of the tabs or windows begins for example to play a sound or video file (which can happened especially for example if the user closes and then reopens the browser automatically with the tabs of the last session, as happens for example in Opera), preferably the relevant tab and/or window is automatically marked for example with an appropriate icon or other preferably visually conspicuous mark, for example above it (and/or for example the relevant preview window is specially marked), so that the user can immediately identify the relevant tab or tabs or window or windows and for example directly jump into the relevant tab or window or for example close it if the sound is annoying (in other words the mark is preferably on or near the square of the relevant application on the taskbar and/or on or near the tab handle of the relevant tab). This is very important since otherwise it can be for example very annoying if the user has for example 20 or more open tabs for example in the browser and for example suddenly for example one of or more of them begin to play a sound file and the user has to start searching for it one by one. Another possible variation is that if a video or sound is already playing in one tab or window preferably the browser asks the user for permission when the new tab wants to start playing a sound or a video, and preferably allows the user for example in the same menu to either choose pausing the already playing sound or video or to pause the new one or for example pause both of them or for example allow both of them to play at the same time. Another possible variation is that for example if there is an annoying sound in a web page, preferably the user can tell the browser for example to avoid playing a specific sound or for example any sounds from a specific domain name or for example specific url or for example all of a certain directory or subdirectories in a url, or for example the user can request the browser to show the command or source which is responsible for example for the last sound heard in a specific tab and can then request the browser for example to never play for example in that url that specific sound again or sounds that sound similar (For example in the site http://bizportal.co.il if the user enters the site with MSIE there is often a very annoying clicking sound, so this is a very good way of telling the browser to get rid of it). Another possible variation is that for example the browser can automatically group together tabs that are related to the same url (for example all Google search results pages) for example by placing them near each other or for example by creating a group icon for the related tabs, for example in a way similar to grouped windows on the desktop task bar. All of these solutions can be applied also for example for tabs for example in the browser or for grouped windows (the use of this with tabs in a browser can be one of the most important uses since typically there can be much more open tabs within a browser than open windows on the desktop). Another possible variation is that for example when putting the mouse over the bottom taskbar or over the tab handles line on the browser, for example the mouse&#39;s scroll wheel (alone or for example in combination with some other key) can cause the tab handles (or squares if it&#39;s the desktop bottom taskbar) and/or the preview windows to automatically grow or shrink in size, preferably for example by automatically reducing or increasing the number of lines used for the tab handles or squares or and/or for the multiple preview windows. Another possible variation is that if there are for example more lines of squares on the task bar than there is room so that a vertical scroll bar is created, preferably for example by hovering with the mouse at the area of the taskbar the user can preferably use for example the mouse&#39;s scroll wheel for scrolling the lines of squares instead of having to drag the scroll bar with the mouse, and/or for example hovering with the mouse for example near the bottom border of the taskbar preferably causes automatically scrolling towards lower lines and/or for example hovering with the mouse near the upper border of the taskbar preferably causes automatic scrolling towards the upper lines of the taskbar. This is much more efficient than having to drag the scroll bar, since it enables much faster control of the scrolling of the lines of squares. Another possible variation is that the user has to click for example somewhere on the taskbar instead of merely hovering over it in order to enable this scrolling by using the mouse&#39;s scroll wheel, but that is less efficient and therefore less preferable. Another possible variation is that for example apart from for example pulling up or down the top part of the taskbar in order to determine the number of lines, preferably the user can also for example vertically condense or expand the height of the taskbar, so that for example the taskbar remains for example two lines but can become for example 70% of the normal height (or any another reasonable percent), for example by the OS automatically getting rid of the unnecessary vertical spaces, such as for example the borders between the squares and/or the distance between each icon to the top and bottom of the square or the vertical and/or horizontal distances between icons on the quick launch area (typically at the left of the taskbar) etc., and/or for example this shrinking of the height of the taskbar lines is done automatically, as explained elsewhere in this application. Another possible variation is that the for example the bottom task bar and/or or for example the browser&#39;s line of tab handles is for example one or 2 lines but when the user puts the mouse over it, it automatically expands to more lines (this way multiple lines can be used when the user intends to click on something there but they don&#39;t interfere with reading web pages when the user is not dealing with the tab handles line), however that can be problematic because it can be confusing if the user intends to click for example on a certain tab but then the automatic expansion moves the desired tab to a different position, so preferably, if such automatic expansion is used, preferably the automatic expansion is done in a smart way so that the current tab (or for example the current box on the bottom task bar) over which the mouse is held (or for example also the other nearest tabs) preferably is automatically kept at the same place even after the expansion. Another possible variation is that for example when the user puts the mouse on the tab handles line preferably the tab line automatically expands for example into a tree structure (for example instead of the original tab line or for example the original tab line remains as it is and the tree expands below it) and/or for example the preview windows are shown in a tree structure. This tree structure can be for example constructed automatically according to the order in which the user reached these tabs, so that for example the roots are tabs which started at the user&#39;s default home page and/or for example Google search pages and the branches continue according to the order of clicking on links that opened the following tabs, or for example the trees are constructed automatically for example according to domain and for example the path length in each domains, but that is less preferable since that would be less relevant to the user. Another possible variation is the user can for example choose or toggle between various options, such as for example showing the tree structures (and according to which rules) or for example showing only the preview windows of the relevant category, such as for example the preview windows of Google search results pages for example when the mouse stands on one of the Google tabs, as explained above, and/or using for example automatically grouped tabs on the tabs handles line. Another possible variation is that for example when the user searches for some web page for example in the bookmarks or history, preferably preview windows are also shown there (for example to the side of the url preferably in the visible section of the list of bookmarks). This can be done for example by the browser automatically bringing the relevant pages and reducing them to preview images for example directly from the web when the links are displayed, and/or for example from the local cache on the user&#39;s computer if available, and/or for example the preview windows are saved in advance automatically somewhere on the user&#39;s computer for example at least for the most recently visited pages, or for example for every bookmark (but that is less preferable since it is much more wasteful). Another possible variation is that the web servers are improved to automatically create in advance preview images of pages (for example each time after they are created or changed)(for example the size of 1:10 of the normal first screen of the page) and preferably submit them directly as preview images upon request (for example by adding a specific convention to the http protocol for requesting them) so that for example the preview image can be requested even without the page (for example by requesting any url with an addition of a code that indicates that only the preview image is requested, and so preferably the browser can for example request the small preview images instantly for example when saving bookmarks or when displaying them, or for example request them from an online database such as for example Alexa, which supplies on-demand pre-prepared thumbnails of a huge number of web pages), or for example the web server adds it automatically as an added data for the page. Another possible variation is that for example the tabs can automatically become grouped, so that for example all the Google search results become automatically represented for example by one Google tab and when the user puts the mouse over it and/or when he/she clicks on it, it expands for example into multiple tabs (for example on a second tab handles lines) and/or the relevant preview windows, and/or for example the grouped tabs are generated according to the above described tree roots or for example like in any of the other variations described above. Another possible variation is that the user can for example push for example with the mouse for example some of the tabs (or for example squares in the bottom task bar) sideways, so that for example the tab handles (or for example squares on the taskbar) from the mouse position up to the left end become smaller and more compressed and so the tab handles (or for example squares on the taskbar) to the right of it become bigger and more clearly visible, or vice versa. (Since dragging a tab handle with the mouse for example in Opera moves only the attached tab, thus changing the order between tab handles, preferably for compressing a group tabs there are for example vertical thin rods that go up between tab handles, so that for example the user can drag with the mouse the appropriate rod to the right or to the left, or similar arrangements). Another possible variation is that preferably the user can also mark for example one or more tabs (for example by choosing from a menu when right-clicking with the mouse) so that they become more conspicuous, so that the user can later return to them more immediately. Another possible variation is that the user can for example use a control or menu choice which closes for example all the tabs for example to the left of the current tab (or for example to the right, but to the left is much more useful since it normally means closing all the previous tabs). Another problem is how to display for example preview windows of windows that themselves contain multiple tabs, for example on the bottom task bar, such as for example the preview window of the browser itself, or for example a preview window of a grouped icon. So preferably the preview window of for example a browser window with multiple open tabs can be for example the preview window of the currently active tab, and preferably next to it (for example above it, for example between the title and the preview windows), for example an indication is given of how many tabs are open in that window, and/or for example the preview window in this can be for example some symbolic preview window for example with a number of small squares that represent the number of open tabs, or for example with automatically generated squares that represent the tabs themselves (for example extra small preview windows of the tabs within the preview window of the browser window, which at least give the feel of the general color of the tabs, or for example a copy of the actual tab handles or whatever part can be made available within the space of the preview window). Similarly, for example if textual choice lines (for example the typical pull up list) are used when clicking on a grouped icon and for example some of the individual windows contain tabs, preferably the number of tabs is indicated near each of them. For example the preview window of a grouped icon can be for example a preview window of the menu of choices that will spring up when the user clicks on it (for example in reduced size on in the normal size, and if the user clicks on one of the options there preferably he/she can enter the desired choice even without having clicked on the grouped icon). Another problem with grouped icons (for example of browser windows or for example word processor windows), is that whenever the user moves for example from the browser window to some other application and then clicks on the grouped icon to go back to the browser, the system automatically displays the choice menu of the grouped icon even though the user would most likely want to return to the same browser window that he/she was previously in, in which case the user has to search again in the list of choices to find this last window, which is unnecessary and inefficient and can be very annoying. So preferably this is improved so the user does not have to search again if he/she wants to return to the last used window of the group and/or preferably also does not have to click more than once for this. So when returning to the grouped icon the system preferably for example moves the user back to the last window of that grouped icon that was in the forefront (for example the last browser windows which the user was looking at before jumping to the other application or applications), and for example only then if the user clicks again on the grouped icon then preferably the choice menu is displayed. Another possible variation is that when the user clicks on the grouped icon the system preferably moves the user preferably instantly back to the last open window of the group in which he/she was, as above, but preferably the choice menu (for example textual, for example line below line as usual, and/or for example by preview windows, and preferably the preview windows also contain for example at their top the title and/or url or other textual information) is also shown for example for a certain short time period (for example a few seconds and/or until the user clicks for example on the window or for example on another window, however preferably the choice menu and/or preview windows don&#39;t go away if the mouse remains over any of them), and so if the user intended to go to another of the windows of the group he/she can simply click on the desired choice, otherwise he/she can continue immediately working in the last window. Another possible variation is that for example when the user puts the mouse over the grouped icon the choice menu (textual and/or for example preview windows) appears (preferably instantly—without any delay) without the user having to click on the icon, and then if the user clicks on the grouped icon preferably he/she is moved preferably instantly into the last window, and if he/she wants to go into another window he/she can click on the desired choice (for example the relevant preview window and/or relevant text choice option), and thus the user still gets to the desired window with one click and does not have to search again if he/she just meant to get back to the last window. Another possible variation is that when the user clicks on the grouped icon the choice menu (textual and/or preview windows) appears and preferably the last windows in which the user was in is already marked and/or pre-selected in the textual choice menu and/or preview windows so that the user does not have to search for it again and preferably just clicking again on the mouse button will bring the user to the last window (so in other words, quickly clicking twice on the grouped icons can bring the user back to the last window, or for example the user has to move the mouse in order to click on the marked and/or pre-selected choice if he/she wants to enter the last window, which is even less preferable, since it involves additional movement with the mouse), however this is less preferable since the user has to click twice in this variation instead of only once in the other variations. Another possible variation is that for example when the user clicks on the grouped item, the last window of the grouped item in which the user was in preferably appears automatically as the lowest option (and preferably appears pre-selected as and marked as pre-selected as described above), which means that the user has the least distance to move if he/she wants to click on that option. Another possible variation is that this pre-selected option actually appears on top of the square of the grouped item, for example by partially or fully covering it and/or it appears for example at least partially transparent so that the taskbar and the square of the grouped item still shows below it, which means that if the user clicks quickly twice on the grouped item he/she will again automatically return to the last item in which he/she was in that group. Another possible variation is that the user can for example enlarge sideways the lengths of the lines which show in the grouped item menu so that more information can be visible in them (so that preferably this becomes the new default until the user changes it again) and/or for example the OS can enlarge it automatically as needed (for example according to the longest title and/or according to the average length of the titles, etc.). Of course various combinations of the above variations can also be used. Another possible variation is that if for example the user is interacting with one application and then for example clicks directly inside an open window of another application (for example Word or a browser or other application), preferably the first click is not removed from the buffer of clicks, so that for example the user can preferably for example mark directly an area in the other application without having to click again. (In the prior art Window the user would have to click again since after transferring focus to the 2 nd  application the first click that was used for the transfer becomes lost). Another possible variation is that for example even if the user chooses not to group multiple windows of the same application into a single grouped icon on the task bar, preferably when closing one of the windows for example from its icon on the taskbar preferably one of the options displayed in the pull-down or pull-up menu is for example “close all open windows of this application” (which is preferably all the windows that would have been automatically grouped together if the automatic grouping was On). Similarly preferably one of the options in the browser is for example to request to automatically close all tabs of the same category (for example from the same domain), for example by clicking with the right mouse button on one of the tabs of that category and choosing from a menu, instead of the normal clicking for example on an X at the side of the tab handle to close just that tab (or for example to close the grouped tab if it is a handle of a group of tabs). Another possible variation is that for example in the Google News (or similar sites) preferably news items are accompanied by a preview window of the item for example in addition to the pictures that accompany some of them or for example for each item that is not accompanied by a picture, the preview window is automatically added instead. Another possible variation is that the screen resolution is preferably automatically raised preferably for example to the maximum available at the areas of the preview windows. This can be done for example by improving the hardware and/or firmware of the monitors (at least for example in LCD and/or SED and/or Plasma monitors), preferably by enabling individual areas of the screen to behave differently in a dynamic way, and/or the hardware and/or firmware of the display adapters and/or their drivers in order to enable setting different resolutions at different areas of the screen, and/or for example the OS preferably automatically chooses or enables the user to choose for example the highest available resolution (for example 1600×1200 or for example 1900×1400), and then the OS emulates the lower resolution which the user normally uses (for example 1024×768) preferably by software and/or for example through the driver, and/or for example the hardware and/or firmware of the display card does it, and so the real resolution is for example the highest but the user sees it for example only in the preview windows and/or for example when playing DVD movies and/or in other specific activities, etc. However, if the system for example enables anyway changing the resolution in a truly independent way that can leave the fonts and/or icons and/or every thing else that is relevant (for example menus, the taskbar and/or anything else in the user interface) unchanged (and alternatively allows changing them, if so desired, independently of the resolution), as described elsewhere in this application, then the user can for example work all the time with the highest resolution for everything (as long as for example the refresh rate and/or performance for example is still high enough) without having to suffer too small fonts or icons because of that). If for example there is a performance or refresh rate issue when working all the time in the highest resolution, another possible variation is that for example the entire resolution of the screen can change preferably instantly to a higher resolution for the time period that the preview windows are shown and then instantly change back to lower resolution, preferably without any noticeable jump or delay that the user can perceive, except for example the lower refresh rate for a brief period. Another possible variation is that preferably the user can activate a command which automatically jumps each time to the next window (for example in the normal task bar on in the internal group of open windows that belong to the same application or for example between open tabs in the same application—for example in the Internet browser), so that preferably each time the user moves to the next window systematically. This is much more convenient than the prior art, where the user has to press alt-tab or control-tab but each time just moves manually to a specific window instead or has to use the mouse manually each time to get to the desired window, instead of being able to systematically traverse the relevant open windows one after the other. Another possible variation is that for example when the user presses alt-tab to move between windows (and/or for example when he/she presses control-tab to move between tabs)(or other similar keys for jumping between open windows or applications or tabs) preferably items in the group of items shown (which can be for example icons and/or preview windows—in other words the preview windows are preferably displayed together next to each other (for example in a few lines and columns) at the same time instead of or in addition to the normal icons, so that for example if icons are also used then for example each preview windows has also the relevant icon, for example above it, preferably together with the title, so that the preview window (and/or icon) and the title preferably show up together as one unit, so that the user does not have to look at two separate places) can also be accessed for example by clicking with the mouse on any of them, instead of the prior art in which only the tab button can move between them and only serially. In addition, if the user for example uses both the arrows and the mouse to move between these icons or preview windows (or for example text lines, as for example when using Ctrl-Tab to move between tabs in the Opera browser), as long as the user is still in the Alt-Tab or Ctrl-tab menu, preferably the arrows pick up from the last position moved to with the mouse and preferably the mouse picks up from the last position moved to with the arrows. In addition, if there are too many icons or preview windows that show in the alt-tab to fit in one screen, preferably a bar handle is added for scrolling the group of shown items up or down. Another possible variation is that this shown group can for example be made to remain visible (and preferably also selectable from) also after the user releases for example the shift or control key (for example by clicking for a longer time, or for example by using a separate key other than control or tab or in addition to it, but more preferably for example if the user moves the mouse into the area of the shown items and/or for example uses the arrows and/or some other key after they are shown, preferably they remain shown for example until he/she clicks on one of them or for example clicks with the mouse outside the area of the shown group, or for example uses some other key to close the shown group). Another possible variation is that at least there is a command which for example allows moving only between the windows of the same group, unlike for example alt-tab, which moves also between the other open windows, and for example control-tab which moves only between tabs of the same window. On the other hand, for example when opening additional pages in the browser as additional tabs within the same window (for example in Netscape or in Opera) there is a problem that for example closing a page with Alt-F4 closes the entire browser window with all the open pages (tabs) instead of just the current page, and for example the normal Alt-Tab does not switch between the tabs. Although typically CTRL-F4 and CTRL-Tab work on the tabs instead, this is less convenient since many users might prefer the same standard controls, so that tabs don&#39;t get a different status from normal open windows, and so that the user does not have to remember for each open page that he/she is viewing if it is for example an internal tab or a normal browser window, and if he/she makes a mistake he/she might close all the open pages that he/she is working with. In addition, in the prior art, if the user has some pages open as tabs and some as another browser windows, this means that switching between the pages requires using both Alt-Tab and CTRL-Tab, which can be very confusing and inconvenient. So preferably this is improved, preferably in the browser itself and/or by the OS, so that preferably for example Alt-F4 (or any other similar accepted convention) closes only the current page (tab) and preferably for example Alt-Tab switches also between the tabs (On the other hand, since some users have gotten used to the CTRL variation, preferably both the Alt and the CTRL variations work the same for the tabs, and/or for example the user can choose what effect the CTRL and the Alt variation will have, and/or at least for example when closing a tab page by Alt-F4 the browser or the OS preferably warns the user or asks if he/she wants to close just that page or the entire browser window with all the open tabs). Another possible variation is that the OS itself automatically enables this, which can be easily done for example if the command of opening internal tabs within a window becomes an automatic service offered by the OS, so that application programmers simply call this service when allowing the creation of tabs within the application Window. Another possible variation is that if the user for example closes a browser window or tab or for example a word processing file window or for example other applications (for example with Alt-F4) he/she can still press some undo button or menu option or key which automatically reopens the last closed window or tab or file. For example, the user might close by mistake a window or tab of an important web page before he/she added a bookmark to it, and might want to instantly restore it as soon as he/she realizes the mistake. This is preferably done by the relevant applications and/or the OS creating automatically a temporary backup of the open window or file for example when the user closes it and/or for example when it is first opened, and/or for example automatically at certain intervals and/or in other events (preferably for example the links (urls) and/or the actual data is saved), and/or for example the OS preferably keeps the information about the application and window in the swap file for at least a few seconds or at least a few minutes (or another reasonable time or until there is no longer room to keep it there) so that for example if the user realizes after a few seconds that he/she closed a window by mistake, preferably the restoration from the swap file is as fast as if the window had never been closed. Another possible variation is that preferably the user can request to automatically reopen the entire set of windows and/or tabs that was opened last time when reopening the browser after previously closing it, even when it is closed normally by the user. This is better than the prior art since for example the browser Opera allows the user to return to the previous set of open tabs only if the browser was not normally closed previously. Another possible variation is that even after the user for example tells the browser (and/or for example other internet application where this feature is used) to start from the beginning or for example closes the various windows or tabs, preferably the user can for example enter some history list which preferably the browser keeps automatically, which preferably saves the previous states of multiple browser windows and/or tabs (preferably by saving only the links in this case), and thus the user can for example preferably scroll back to any desired set of tabs and/or windows that were previously open together and can preferably for example with a click of the mouse go back to that same state of multiple open windows and/or tabs (preferably the entries in this list are kept least for a certain time and/or at least until the list reaches for example some maximum size, and then the oldest entries can preferably be deleted automatically if the space is needed, however if only the links are kept then the list can be kept even without any automatic deletion, unless for example the user requests this explicitly, since very little space is needed for this). Another possible variation is that for example the browser or OS or other application preferably allows the user for example to reopen closed tabs and/or undo other changes in the tabs even after for example the browser itself is closed and reopened, preferably by saving automatically also the history of changes in the tabs for Undo, so that for example using for example ̂Z (or other convenient command) will undo closing of tabs, moving of tabs, etc., even if the whole browser window has been closed and then reopened with these tabs, and preferably redo also works here, preferably including multiple branches in the redo when needed. (Although the Opera Browser for example allows the user to press ̂Z to reopen closed tabs, this does not work for reopening closed windows or for reopening closed tabs if the browser is closed while these tabs are closed and is then reopened. In addition, in Opera if the user is in an email-message-composing tab, the ̂Z works on undoing typing or deletion within that tab instead of restoring other tabs, so this is preferably improved so that undoing the typing in the composition tab uses a different control, or for example the user has to hover with the mouse outside the typing area in the composing tab on order for the ̂Z to restore closed tabs instead of undoing typing in the composition window). Another possible variation is that the last search string or history of recent search strings (and/or multiple search strings if separate search strings can exist for example in separate tabs at the same time) is preferably also saved automatically preferably together with the tabs, so that when the window is reopened after being closed preferably the search string or strings are also preferably automatically available from at least the previous session. Another possible variation is that for example fields in which the user entered data, such as for example in forms or for example data that the user enters when composing an email message, are also automatically saved (for example every few seconds and/or after an amount of small change, for example after every N characters or words, and/or upon closing) and are preferably automatically available again when the user reopens the browser. Another problem is that for example if the user opens in the web browser multiple web pages that are pdf documents, the pdf-viewing helper application is reopened again for each tab, and so the search string is not remembered automatically between such tabs. So preferably this is improved so that the browser automatically remembers the last search string (or for example most recent search strings) also for example for pdf files (and/or other formats which are viewed with a helper application) and preferably transfers automatically for example the last search string to the pdf viewing application when opening the next pdf file in a tab. Another possible variation is that the user can for example mark for example with the mouse multiple tabs (for example by marking their top handles, for example by pressing shift and clicking on the start and end tab of the desired group) and then can for example close the entire marked group for example with a single click or key. Another possible variation is that the user can for example use a command such as “refresh-all” or “reload-all” (preferably for example by clicking on such an icon or menu item), which causes refresh for all the currently open tabs. Another possible variation is that preferably when the user saves a file under a different name, for example in the word processor, preferably the user has also an option to request to automatically keep open also another window with the original file. This can be very useful for example in case the user wants to work for example on one copy with marked changes and a second copy where the changes have been accepted. Of course the user can do this manually by first saving the file under a different name and then reopening the original file name in another window, but it is more efficient to add such an automatic option to the application so that the application can do this automatically for the user. Another problem is that for example when trying to delete a directory through a command prompt window in windows XP the OS only asks “are you sure” without even letting the user know that this is a directory. This is very dangerous since the user might this way inadvertently remove even a huge directory tree. So preferably this is improved so that instead the OS tells the user that it is a directory and preferably tells him/her also the number of subdirectories and/or the total number of files in that directory tree and/or the total size. Preferably the OS also lets the user choose as one of the options a controlled deletion so that for example the user will be automatically asked to make the same choice for each sub-directory of the chosen directory and/or for example asked to verify the deletion of each file. In addition, preferably especially when deleting directories, preferably the system automatically keeps a backup of the directory structure and/or a rollback log, so that if the user made a mistake the directory tree can preferably be instantly restored. This is very important since eventhough there are for example various programs that enable searching for deleted files and restoring them, restoring a full directory tree without automatically saving first a copy can be much more complicated and less reliable. Another possible variation in that the user can preferably request to copy with automatic individual file conformation for example one or more directories (for example from a DOS or CMD windows or for example from an explorer window), which means that preferably the user is asked to confirm if he/she wants to actually copy each file one by one (regardless of whether the file already exists in the target destination or not), and/or for example request to copy only files which were created for example be and/or after certain dates. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features.   25. Another problem for example with SED monitors is that they have a brightness of only half or less of a comparable CRT monitor, probably because in the way that they are normally built increasing the voltage further could cause an uncontrolled discharge for example sideways. Therefore this is preferably solved for example by adding borders between adjacent pixels, preferably for example by surrounding each pixel by preferably thin walls and/or other type of wave guide or wave guides that preferably go at least part of the way or even almost all the way till the front glass (and the walls can preferably for example also contain some preferably thin internal metal coating), which can be a small added cost since such monitors are typically manufactured by printing in a way similar to an inkjet. Such walls and/or other wave guides and/or other means from improving the local precision of the individual electron beams thus preferably serve as wave guides for the electron beams and, apart from preferably enabling using higher voltage and increasing the brightness, they can have the additional advantage of increasing the precision of the direction (and thus the exact position) in which the electrons hit the phosphor, and thus reduce even further the need for using a shadow mask, so that preferably only a very thin mask is used or even no mask at all, or for example elongated slots like in Trinitron monitors are used but in a way that the borders between the slots are preferably thinner than in a Trinitron monitor. This can thus further improve the brightness and/or the color rendering so that the SED can preferably give better brightness and/or better color rendering than even Trinitron monitors. Another possible variation is that for example every once in a while (for example every few centimeters), for example some of the walls or for example small spikes at the ends of some of them can preferably reach all the way to the front glass, thus increasing the stability of supporting the flat front glass eventhough there is typically a vacuum between the back part and the front glass. Another possible variation is that there are for example small holes at the back of the cells that generate the electrons in the SED monitor or at least in some of said cells, so that for example the vacuum can be created by sucking the air out of a layer at the back of the cells. Another possible variation is that preferably (for example in SED monitors or in other monitors) the monitor&#39;s control can be done for example with a preferably single moving element, for example similar to the rotate-able button on the front of Mag monitors, except that preferably instead of a rotating button there is preferably an element that can be moved freely for example in all directions with a certain frame of possible movements, thus giving the user an ability to choose anything on the screen or on a certain area of it without being limited to a circular menu like in Mag monitors. This moving element can be for example a moveable piece of plastic attached for example at the end of a needle which for example goes into the depth of the bottom front panel of the screen, which can be moved in any direction for example within a square frame border, so that for example its position can be sensed by the angle of the needle. Another possible variation is to add for example in portable computers preferably (instead of the square which is typically used as a mouse substitute) for example a small ball or other small handle which the user moves on an area for example with the same size of the typical square or even bigger. This is important because many users feel uncomfortable with having to drag their finger on the square. This ball or handle can be connected for example in a way similar to the above described moving Monitor control button—for example by attaching it to the end of a needle, or for example it is connected magnetically to a magnetic plate and preferably moves a parallel magnetic element on the inside which is sensed, or for example the movements of the external element are sensed directly for example electromagnetically or for example through induction. Another problem with Mag monitors is that in order to switch from the normal monitor&#39;s menu to the hidden menu which has more options and can change factory settings (This menu is hidden because users who are not technicians might easily screw up these settings) the user must keep the round navigation button pressed while turning the monitor off and on again, and then again turning it off in order to return to the normal menu, which is very unhealthy for the monitor. So preferably this is improved so that for example for switching to the factory settings menu preferably the user has to keep the navigation button pressed for example for 10 seconds or more (or other reasonable time limit), preferably while it is pointing for example to a specific menu option (preferably any normal option which is used normally for something else) or to one of a few specific menu options (so that it does not happen by accident), and for returning to the normal menu preferably the hidden menu has for example a normal exit option which the user can simply choose through the navigation button. Another possible variation is adding for example a hidden small switch for example on the bottom side, for example somewhere below the round navigation button, but this is less preferable because is means adding additional electronics, while the above solution is much cheaper and more efficient. Another possible variation is that preferably these OSD (On-Screen Display) Menus are transparent or can be made more or less transparent for example by an additional option within them, so that the user can more easily see what is on the actual computer display even while the OSD menu is on. Another possible variation is that preferably the various menu items in the monitor have an undo function so that preferably the user can click on an option that resets them for example individually or as a group to the previous value before the last change.   26. Another improvement in Windows Vista is that the OS automatically identifies the applications which the user most typically uses and loads part of them automatically in advance during the boot. However, this can still be inefficient since it can slow down the boot process itself. So this is preferably improved for example by combination with saving the image of a correctly booted system and using it for the next instant boot or reset. So preferably the OS adds to this image also these most commonly used applications, so that they can be loaded instantly together with the image of the OS and other start-up programs. However, since the user might not really want to activate these programs each time, preferably they are loaded into memory with a flag that causes them to be actually inactive, so that preferably they become active only after the user actually tries to open them.   27. Another improvement in Windows Vista is that the user can view virtual folders, which unite together for example “all pictures and videos” etc. However, since these are only logical and not actual folders the user for example cannot copy additional files directly into such folders, which creates a consistency problem compared to normal folders and can therefore be annoying or confusing or inconvenient. So in order to improve this preferably the system allows the user also to copy files (and/or other directories) also into such virtual folders. Preferably this is done for example by intelligent decisions which real folder to use in association with this. For example the OS can decide that the new files will be copied to the largest relevant real folder (for example the folder which currently contains the largest number of files of the relevant type, for example photos or video or music files, etc.) (which can be easily determined for example from the local desktop search database) and/or for example when the user copies files to the virtual directory the system for example automatically show the user a selection of actual directories that are recommended and the user can for example click on the desired one and then the copy will actually proceed into there. Another possible variation is that for example for each such virtual folder an actual folder is also created automatically (for example with the same name) so that preferably any subsequent files copied to the virtual folder will be simply copied to the physical folder that is associated with the virtual folder of that name, and for example when viewing the virtual folder, both the virtual contents and the actual contents of it are shown together or for example in separate categories. Another possible variation is that for example the system can preferably display, preferably instantly upon request, (for example with the help of the indexed desktop search), for example a descending list of the largest files and/or directories and/or subdirectories and/or for example mark especially those files that also have not been used for a long time and/or are rarely used, so that the user can for example most efficiently get rid of unnecessary junk on the hard disk or disks. This can preferably be done also across partitions and/or across physical disks, if there is more than one disk (although there is a program called TreeSize which does something similar, that program works only within each partition, and also Treesize only displays the sorted order of directories and subdirectories but does not sort by size the files in the directory itself). Another problem in Windows Vista is that the security feature that requests user confirmation too often causes people to start ignoring it after a while and click on “Allow” almost automatically. So preferably this is improved so that the system takes into account if the user or an application initiated the action (as explained for example in other applications which deal with computer security by the present inventor), and this is preferably applied at least to OS functions, so that if for example the user himself/herself for example clicks on a menu item which activates some system function, preferably the OS does not ask the user for confirmation (but more preferably this is not limited to OS functions, as explained in the above mentioned applications). Another problem is that in the new Vista Beta 5365 of Apr. 22, 2006 when the OS requests this permission the entire screen becomes dark except the authorization dialogue box—in order to freeze other applications until the user answers so that they cannot interfere with this. Again, a much better solution is described in the above security applications by the present inventor—so that preferably other processes don&#39;t have to be frozen until the user replies but the OS and/or Security system prevent other applications or drivers etc. from interfering in the dialogue so that they cannot for example change the message or falsify the user responses, and preferably similarly for example the OS and/or the security system (or for example other application or service which is in charge of this) preferably prevents other applications or drivers for example from displaying a misleading message for example on top of the message displayed by the OS or by the security system (thus for example changing the question or the positions of the Yes and No, etc.).   28. Another problem is that for example various programs or drivers refuse to install on various betas of Windows Vista because they don&#39;t recognize the OS version. So in order to solve this preferably the OS enables the user to specify for example what name or and/or other codes the SO will identify itself by to various applications, so that for example the user can preferably tell for example Windows Vista to identify itself (for example in general and/or for example to a specific list of applications for example as Windows XP). Another problem is that for example in windows XP the cmd window does not show anymore also the short 8-letter names of files with names longer than 8 characters, unlike Windows 98. But this is problematic if the user wants for example to open such a file for example with a DOS application that sees only 8 letters because then the user does not know the correct DOS name that the DOS application will see (typically a few letters and then a ‘-’ and then 1 or 2 letters). So preferably the user has for example a choice if to let the cmd window display also the short DOS names for file names, and/or for example if the user activates the DOS program with the long file name then preferably the system automatically converts the file name parameter to the correct short name before transferring it to the DOS program (in the prior art in such a case only the first 8 letters are transferred and then the DOS program cannot open the correct file if the name is longer than 8 characters because it does not get the correct name with the ‘-’). Another possible variation is that preferably for example when DOS or CMD windows are opened, preferably the OS for example remembers automatically not only the size of the window but also its position on the screen, so that preferably at least when there are no other already open CMD or DOS windows preferably it is opened at the same position on the screen as the last such window which was last closed, and if additional CMD or DOS windows are opened then preferably they are automatically opened at certain shift from the original position. This can be very convenient since normally a user would prefer such a window to be on a usual position convenient to him/her, but in the prior art Windows the first CMD or DOS window is always opened at the same place, while the user might always prefer to put it for example at another position, so he/she always has to drag it manually after opening it. Similar rules can be applied of course also to other part-size windows which the user might open frequently. Another possible variation is that preferably the user can enlarge CMD windows to any size desirable and preferably at least at the CMD shell (i.e. when the user interacts with the CMD window itself, as compared for example with interacting with an editor that runs in the CMD window) the line wrapping can preferably be automatically adjusted to the new width. This is better than the prior art, in which the CMD window cannot be made wider then the default and for example making it thinner creates automatically a horizontal scroll bar.   29. Preferably file sharing programs which download files from multiple other users are preferably improved so that when the same file is available from multiple sources, they preferably download from each available source sections in preferably random order (so that for example from one source the end parts are downloaded, from another source middle parts, from another source parts at the beginning, etc.). This can prevent the phenomenon that, since certain files become no longer available during the process, typically the downloading becomes progressively slower near the end of the file. Another possible variation is that preferably for example such programs and/or torrent sharing programs preferably download first the parts which lowest availability among the currently sharing users (in order to leave for last the parts which more users have) and/or for example preferably downloads that are about to finish and need a specific part get higher priority than downloads which just started and so can get any part. Another possible variation is that for example preferably any searchable files in the shared directory or directories are automatically converted into torrents, so that the file sharing program automatically ensures that for each specific file downloaded the downloading user will also upload it. Of course various combinations of the above and other various can also be used. Another possible variation is that for example when downloading a video torrent file the user can for example request to first get for example the first 5 minutes (or for example other reasonable time frame and/or for example one or more sections not necessarily at the beginning, and then preferably the torrent downloading program preferably downloads the requested section or sections preferably with highest priority and preferably automatically downloads also the relevant info for the file which is needed for playing this section or sections properly (such as for example the resolution, bit rate, etc., which can for example at the beginning and/or end of the file), so that preferably the user can for example use this to almost instantly watch a sample in order to see if indeed that is the correct file that he/she expects or for example to get almost instantly a section which he/she likes most, such as for example a specific song within a long video, etc. (In order to prevent misuse this feature is preferably limited for example up to a certain maximum absolute length, such as for example a few minutes or 10 minutes or other reasonable maximum cumulative time length, and/or for example up to a certain percent of the entire size of the file). Another problem is that for example when the user chooses to open for example a non-streaming media file (such as for example mpeg or avi or wmv) on a web page the browser first downloads the file into a temporary directory and then activates the relevant player application only after the file has completed downloading, which causes additional delays. So preferably this is improved so that the browser opens the relevant player application in advance, so that when the file finishes downloading the player is already open and ready. An even more preferable variation is that the browser or the relevant player preferably check automatically if the file can start to be played even before finishing the download and/or if necessary the browser preferably downloads in advance for example any general info which is needed for the playback even if it is for example at the end of the file, so that for example even an avi or wmv preferably starts by default to be played automatically while being downloaded (unless for example the user cancels the automatic play). Another problem is that for example if the user made a mistake in entering the desired local file name when downloading a file for example in the browser or changed his/her mind, then the file can only be renamed after the transfer is finished, or the user has to stop the transfer in the middle and delete the file and start again the download. So preferably this is improved so that the user can also change the file name while it is being downloaded without disturbing the download process (for example through the right mouse button menu). Preferably this can be done for example by the browser (or other relevant application) immediately displaying the new name but actually renaming the file automatically only when finishing the download, or, more preferably, the browser (or other relevant application) for example automatically pauses the download for a split second, renames the file, and then automatically reopens it with the new name and resumes the download (the entire switch preferably takes much less then a second), and/or for example the OS&#39;s file system is improved so that a file can be renamed even while open, without having to close and reopen it (there really should be no problem in doing this because there is no reason why the name of a file in a directory entry cannot be changed even while there are open handles that point to the file). However, actually for example currently Opera does not even allow to rename the file after the download is complete, so preferably the user of course can also rename the file after the file is complete, so that it changes both in the file system and in the list of transfers, just like when changing it while downloading, as explained above. Another possible variation is that preferably the user can also for example change in the middle of the download for example the target directory, and in order to enable this preferably the browser for example automatically copies the already downloaded part to the new directory in the background, preferably while continuing to download (for example to the end of the original file or to some temporary buffer), then preferably appends to the new copy any additional data that was downloaded while the file was being copied, and then deletes the original file and, if used, also the temporary file. However, if the other directory is in the same partition, preferably the browser uses “Move” instead of copy, and in this case preferably it works like in the rename, without copying to a new file. These methods can preferably be used also for example when downloading files for example through torrent downloading applications. Another possible variation is that for example if there is a temporary disconnection from the web for example in systems with a cable modem and the dialer then reconnects automatically for example immediately or after some time, then preferably downloads that were stopped by the disconnection, such as for example downloads in the browser or for example in torrents or other p2p applications preferably resume automatically, for example by constantly or periodically monitoring the connection (for example once every few seconds or for example once every minute or other reasonable interval) to see if the connection as been restored and automatically resuming when the browser or other relevant application senses that the connection has been restored.   30. Another preferably improvement is that when more than one OS is installed on the same computer the user can preferably easily switch the default OS to whichever option he/she wants and/or for example change the order of the options (where typically the first option becomes the default). This can be done for example by letting the user drag an option line with the mouse to a different position in the screen that asks which system to boot or for example press some key or key combination. This is very important, since in the prior art if the user for example installs Windows XP over a system of Windows 98 (so XP automatically becomes the default) and then prefers to use for example Windows 98, it can be very frustrating to have to change the choice each time when booting, and this is also important especially for example if there is a power failure and the computer reboots automatically. Although XP for example allows changing this by performing a few steps after the XP has finished booting, which most users don&#39;t even know how to do, it would be much more intuitive to let the user for example move the option lines with the mouse in the screen that asks which system to boot, as explained above. This means that preferably basic or standard mouse support is preferably activated at least partially already at this stage eventhough no particular system has been activated yet. Another possible variation is that the system automatically remembers the boot option that was last chosen and makes it automatically the default for the next boot until the user changes it. (Another possible variation is that this option also automatically becomes the first choice on the boot menu on the next boot, but that is less preferable since it might confuse the user if he/she is used to a certain order of the boot options and did not choose explicitly to change it). Another possible variation is that if the user for example chooses some option in the boot menu and then regrets it and the system for example has already started to boot according to the chosen option, (for example choosing Windows 98 in a boot menu that has both Windows XP and Windows 98) preferably the user can for example press some button which can preferably return the user preferably instantly or almost instantly to the boot menu preferably without having to reboot the computer. This can be done for example by saving automatically an image of the state of the computer when the boot menu is reached, so that preferably this state can be preferably instantly loaded again from that image for example when a return to the boot menu is requested. Another possible variation is that if there is for example more than one bootable hard disk (or for example other forms of non-volatile memory which function as hard disk replacements) (which can be reached for example by pressing F8) and this disk is not covered by the normal OS-generated boot selector, preferably the BIOS can sense this automatically and can create automatically—and/or for example the user can choose this from a menu in the BIOS—an additional pre-boot selector, which preferably shows up automatically when booting without having to press F8 and lets the user choose between the two or more bootable hard disks (or other non-volatile memory options), and preferably in this boot selector also the user can preferably for example move one or more of the options to be before the others and/or for example the BIOS remembers automatically the last choice and uses it as the defaults the next times until the user chooses again differently, and preferably after for example 5-30 seconds (which preferably the user can change through the BIOS) the last default options is automatically chosen. Another possible variation is that the user can for example through the BIOS or through the OS, preferably without needing any additional installations, for example preferably easily add this additional boot option or options to the normal boot selector that was generated by the OS, if such a boot selector already exists (for example by simply adding one or more lines to the Menu during the Boot or in the Bios or from the OS and adding the drive letter of the additional option and some name or description of the additional boot option or options), and thus preferably there is only one united boot selector instead of having to wait twice or choose twice. Another possible variation is that preferably the BIOS enables 32 bit transfer by default, preferably for each hard disk that is detected and/or is capable of supporting it. Another possible variation is that preferably when installing a new OS preferably the OS automatically adds at least the relevant drive letter to the name of each option in the boot selector according to the drive letter on which the relevant OS is installed (and/or this is done later, for example by one of the installed OSs), and preferably at least if for example more than one OS exists on the same drive letter then preferably the path is also added automatically. In addition preferably the exact version of the OS is also added automatically, so that if for example the user installs a few betas of Vista on different partitions then preferably the build number of each OS is preferably also automatically added to each option in the boot selector. This is very important since for example when installing additional betas of Vista it very difficult to get rid of previous installations without reformation the relevant partition (and also the user might for example want to keep also at least some older versions to make comparisons), so if the user installs each beta in a different partition, it is much more convenient to see also the build number of each OS in the boot selector. Similar information (such as for example type of OS and/or drive letter and/or path and/or version number) is also added preferably for example to options in live OS selectors which enable switching between OSs for example in systems that support two or more OSs running simultaneously. Another possible variation is that preferably the last OS in which the user was before the boot preferably becomes automatically the default choice in the boot selector, at least for example if the boot is done within a certain time of being active in the last session—for example within N minutes of the last shut-down, or for example without time limit. For this preferably the boot selector keeps preferably in a file the last choice, and if there is also a time limit then preferably there is at least one process of the boot selector which keeps running even after the boot and preferably keeps updating at short intervals some variable which indicates the time of the last access to the current OS (This can be done even more easily for example in systems that run multiple OS&#39;s by adding this function to the hypervisor), or for example upon the next boot the boot selector preferably automatically checks for example the date and time of the swap file (or some other constantly updated file) in each of the OSs and thus can know how long ago the OS was last active. Of course in systems that run multiple OS&#39;s the definition of which OS was running is different, so preferably is this case the boot selector preferably remembers as default for example at least which OS was the first booted OS in the last time the system was booted, and preferably the other OSs are activated automatically or by the user after the first OS finishes booting. Another possible variation is that for example the hypervisor or the boot selector can remember also which OSs were active in the last session and can preferably automatically reopen them after reboot, except for example if there was a problem in one of them, in which case preferably the hypervisor for example preferably asks the user if to allow also the problematic OS to run. Another possible variation is that upon reboot, after the hypervisor finishes booting preferably multiple OSs can boot at the same time, without having to wait for one of the OSs to complete booting before the others. Another possible variation is that for example when choosing Restart from the start menu, preferably the user can also choose for example to restart into another OS, so that the user does not have to sit near the computer while it restarts and wait for the boot selector to choose the other OS. In order to enable this preferably the OS automatically copies the same options that are available in the boot selector and preferably displays them for example as a sub-menu of the Restart menu, and when the user makes his choice this is preferably saved into some file which the boot selector checks or for example the default boot choice is temporarily changed. Another problem is that for example even when starting the installation of a new OS from an existing OS—for example when starting the installation of Vista in a new partition from Windows XP, the new OS only remembers the drive letters of the partitions on the hard disk or hard disks, but does not remembers the drive letters that were used for other storage devices, such as for example CD or DVD readers or burners or Zip drives. So preferably this is improved so that during the installation preferably the installing OS remembers also the drive letters of these devices and/or additional parameters (preferably by saving them in a file which is then read also after the subsequent boots). Another possible variation is that when installing a new OS in another partition and then installing applications in it, preferably the user can request the OS or for example a specific application to automatically import from a previous OS installation for example the relevant parameters from the user settings of the other OS, so that preferably the user simply has to give the OS or the application the drive letter of the other partition and then preferably the OS or the application automatically searches the relevant directories there (which will typically be the standard documents and settings directories) and preferably copies automatically preferably all the relevant parameters from there, and/or preferably the user can tell the application to share the same settings with those of another OS installation, so that preferably changes to the settings from either OS are automatically visible also to the other OS (This can preferably be done for example in a normal system where the user passes between OSs by rebooting or for example in systems in which more than one OS run concurrently).   31. Another problem is that for example in wireless networks (for example in homes or offices) the only method of protection against stealing data and/or illegal tapping into communications is encryption, which has already proved not reliable enough. Therefore another possible variation is that in order to improve the security of wireless networks preferably the network computers use also for example automatic triangulation of the source of transmissions (preferably by using for example all or some of the known devices in the network to compare the strength of the signal that they receive), so that for example the coordinates of the allowed space are entered into the system and/or for example only specific locations of known devices are white-listed, and so for example any intruder from an outside position cannot pretend to be an authorized user even if he succeeds in finding a vulnerability in the encryption. (Although this still does not prevent passively listening-in, preventing any other form of interaction can be very effective, since for exploiting various vulnerabilities typically at least some interaction as needed, so this together with encryption can be very effective).   32. Another problem is that for example Microsoft is now trying to market in low-income countries such as for example China and India a considerably cheaper version of Windows XP, however this version has some serious limitations that make it much less attractive to users, and one of the most severe limitations is that for example only a very small number of programs can be run at the same time. This can make the OS much less useful, so very few people will be willing to use it, even at a half price or less, and thus the main purpose (reducing piracy in those countries) can be completely defeated. Therefore, a much better solution is to let users buy the OS at such countries at such a low price preferably with few limitations or no limitations or at least no limitations that result in reduced functionality to the user, and preferably prevent loss of profit in other countries where the OS can be sold in normal prices—by limiting the use of the discounted version in the other countries. This can be done for example by at least one of the following means:
           a. Limiting these cheap versions so that at least part of the interface and/or some important applications work only in languages that are not useful to most people outside the cheap countries (for example only Indian languages or Chinese languages).   b. Displaying a warning for example whenever the OS is started that it is illegal to use this version of the OS in any either countries than the list of qualifying countries, unless for example the user has a citizenship of one of these countries and/or is resident there, etc.   c. The OS can Check for example automatically when the user connects to the internet if his/her IP address is in one of the qualified countries and, if not, require for example some certification to be filed (if it hasn&#39;t been filed yet) which proves that the user is entitled to use that version of the OS outside of those countries. Preferably in these cases the OS can automatically stop working or start working with only limited functionality after a certain time period (for example one month) if said certification has not been filed.   
           33. Another problem is that for example in Windows XP if the system is unable to read a CD then the entire system can get stuck without any explanation to the user, since the OS apparently tries again and again incessantly to read the CD. Preferably this is solved by automatically aborting any attempts to read a problematic CD preferably after a short time (such as for example 20 seconds or 30 seconds or other reasonable preferably pre-defined threshold, which preferably can also be changed by the user) and preferably indicating to the user the nature of the problem and preferably letting him/her decide what to do, and/or for example allowing the user to press some key or otherwise request immediate aborting of the attempts to read the CD (this is preferably done for example by some element below the OS which does not get stuck even if the OS gets stuck, and/or for example the OS automatically interrupts the attempts to read the device at short intervals (for example at least once a second or more) and then checks for example if any commands have been entered by the user.   34. Another possible variation is that preferably the user can tell the OS for example not to enter sleep mode until a specific application has finished running, for example by clicking on the application&#39;s window or for example on the square that represents it in the task bar and marking the relevant option in a menu (preferably this can be done for example for a specific currently running Window of the application or defined in general for that application, so that for example every time automatically the OS will not enter sleep mode if that application is running and has not finished yet). Another possible variation is that the user can for example tell programs that play media, such as for example songs, for example Winamp, to stop working automatically after a certain preset time period (for example 30 minutes or any other convenient time period) or for example after a certain number of repetitions of the current playlist (for example there are 5 songs in the playlist and the user marks that the program should go for example though 3 cycles of playing the songs before stopping automatically) or for example after a certain number of songs (for example from a selected subgroup or from the entire play-list, for example at a given order or in random order), and/or for example the user can mark individually for specific songs how many times to repeat it, which can be very useful for example if the user wants to fall asleep with music in the background but without the music continuing all night (This is preferably done by the application itself, but preferably it can also be done for example by the OS). Similarly preferably the user can tell for example programs that are downloading files or other programs for example to stop automatically after a certain time period if the user is away, or for example tell the OS or the firewall to automatically disconnect the computer from the Internet if the user is away for more than a certain time limit (for example after 1 hour or more) and/or for example to stop automatically if one or more conditions occur. Another possible variation is that for example the user can simply indicate or mark to the OS a set or range of hours in which the computer will automatically go into sleep mode (hibernate) at a certain set of hours, for example during night hours (preferably unless of course someone is working on it). Another possible variation is that for example all-in one printer-faxes, such as for example by HP, which once in a few hours automatically calibrate themselves, thus making noises, are preferably automatically configured to avoid doing that, at least for example during night hours, since it can be quite annoying if someone is woken up by these noises (This can be done for example by using a light sensor and/or according to the local time settings, and/or preferably the user can of course define the desired quiet hours). Another possible variation is that for example, when needed, the calibration is done for example only after the user clicks on the keyboard and/or for example moves the mouse (this gives it sufficient time to do the calibration before the actual printing, so that the user does not have to wait when printing, but ensures that the calibration will not occur for example when the user is asleep). Another possible variation is that preferably the calibration is done automatically immediately after printing if needed, however this could still create a problem if for example a fax is received at night. Another possible variation is that for example during night hours (as determined for example by light sensor or sensors and/or by the local time setting), preferably faxes are automatically only stored in memory (for example unless the memory becomes full) and are automatically printed for example only after a certain time in the morning and/or a time which the user can set as default and similarly preferably no ringing noise or connecting noise is emitted by the fax during those night hours, and/or for example similarly automatic answering systems and/or phones and/or cellular phones and/or smart phones can preferably make themselves automatically silent during night hours and/or during darkness time (which means that incoming phone calls are preferably automatically routed to the automatic answering system or service without making a ringing noise), as determined preferably by light sensors and/or for example by clock preferably with default hour settings which the user can preferably change, although preferably the user can of course enable or disable these features. Similarly, if the user for example travels to another country and for example his cellular phone automatically continues to receive calls, if the silence time is for example determined by light/darkness then this can continue to work properly automatically, and if for example it is determined also by clock time then preferably the cellular phone gets automatically the local time from the cell system in the new country and thus the time rules can also continue to work OK in the new time zone. Preferably the system allows the user example to enable or disable the feature of quiet operation during night time and/or define the relevant time limits. Similarly, another problem is that for example typical firewalls (such as for example Zone Alarm) are programmed to close the connection to the web automatically for example when the screen saver activates, which is usually quite useful, however sometimes the user for example might want the firewall to keep the connection open for example until one or more download operations are completed. For this preferably the user can also similarly preferably indicate for example that the firewall should not close the web and/or for example the screen saver should not be activated until the application has finished performing some operation. Another problem is that for example multifunction printers like for example HP&#39;s 6110 refuse to scan documents or send faxes if for example one of the two printing heads (the black or the color) is missing or otherwise not responding properly, eventhough this means that there is really a problem only for printing, which can be quite annoying or even dangerous for example if the user needs to send an urgent fax. So preferably this is improved (preferably by changing the firmware) so that preferably problems with printing do not disturb the printer from carrying out other functions such as for example faxing or scanning or receiving faxes into memory, so that preferably the printer keeps performing functions as long as the elements which are needed for that function are still functioning (preferably for example by keeping a separate list of necessary elements for each function). Another possible variation is that preferably even after printing a fax preferably the fax is not erased from the machine&#39;s memory (for example at least for a certain time period and/or for example as long as there is sufficient room), so that for example if there was a problem in the printing which the device did not notice (such as for example mistaken feeding of two pages with a shift between them instead of one page, so that the fax is actually split between two pages on the printing, or for example ink that ran out during the printing or for example got smeared), or for example if the user wants to print more copies of the fax without having to rescan it, which can reduce quality, preferably the user can access for example through the Fax&#39;s menu for example a list of recent faxes and reprint any of them, and/or for example similarly recently sent faxes can automatically be kept in the machine&#39;s memory at least for a certain time and/or as long as there is sufficient room, so that the user can for example review them or print a copy of them or for example resend them without having to rescan the relevant pages. Another possible variation is that preferably the user can tell at least fax machines which are also multifunction (i.e. Include a scanner and a printer) for example until further change to automatically send all incoming faxes (and/or even for example outgoing faxes) for example automatically also to the computer into a file (so that the faxes can be saved automatically also on the computer) for example in addition or instead of automatically printing incoming faxes, which can also be useful for example for avoiding printing junk or spam faxes, and in this case preferably the fax machine asks the user before printing each fax. Another possible variation is that for example whenever the user updates the firewall (for example zonealarm), which typically requires shutting down the current working version of the firewall during the installation, preferably the firewall and/or the system automatically closes any internet connections and/or for example activates some other process which temporarily for example makes sure that all Internet activities are frozen, until after the new firewall is installed and starts to work, otherwise the computer can be dangerously exposed during the installation. Another possible variation is that for example the modem can receive a command for example from the firewall or from the OS to shut itself down (which can preferably be done automatically for example when the firewall is updated or when the OS goes to standby or reboots), however if this is enabled then preferably the modem can then be automatically powered on again only if it has not been powered off manually by the user (otherwise this would create a security risk of being able to power on the modem even after the user physically powered it off). Another possible variation is that for example any installation of a new program and/or any uninstallation automatically triggers creating of at least one restore point by the system (but preferably two—one before and one after the action) and preferably the System and/or the security system (or for example another application which takes care of it) preferably automatically adds to each such automatic restore point also a description of the situation when it was done, such as for example “before uninstalling zonealarm 6.0” after uninstalling zonealarm 6.0 or “before installing opera 9” and “after installing opera 9”, or for example automatically any time the registry is about to be changed (for example by detecting automatically that the install shield has been activated or for example by hooking or monitoring the relevant system functions). Another possible variation is that the screen saver menu available for example at the windows desktop preferably enables the user also an option of for example displaying a simply preferably fully black screen (or almost fully black, with an additional preferably small preferably dim preferably slowly moving indication that the screen is still turned on) after a certain time instead of or in addition to the option of turning off the monitor (which means instant return from a seemingly turned off monitor), so that for example the user can choose for example activating the normal or first screen saver after for example 15 minutes (or any other convenient time) of no user activity and activating the fully black or almost fully black screen (and/or for example any other screen saver chosen as 2 nd  step screen saver) for example after 25 minutes (or any other convenient time) and turning off the screen for example never or after some other period). Another possible variation is that for example for every given screen saver (or at least for example some of them) the user can preferably easily change the color of the foreground and/or background and/or for example move some bar or other control or command which changes the brightness level of the screen saver for example from fully lit to very dim, which is preferably taken care of by the OS or by some other application. In addition, since sometimes the screen saver can become turned off for example by mistake or by video playing applications which temporarily deactivate it but sometimes fail to restore it, preferably in such cases the system can warn the user about it (at least for example if the screen is a CRT or SED or Plasma or other screen which can suffer from burnout), for example by indicating to the user the next time that he/she comes back after a certain period of inactivity that the screen has been fully active and/or stationary without any need for example for the last N hours and recommending the activation of one of the screen savers, and/or for example with such screens the system does not allow the user to define no screen saver and in such a case of deactivation or for example if the time the user chooses for activation is too long (for example activate only after 1 hour or more of inactivity) the system for example automatically enforces at least some minimal screen saver rules (this means that preferably the auto-detection of monitor brand and model preferably includes also an indication of the monitor type) and thus preferably automatically restores the screen saver. Another possible variation is that preferably when desired the user can for example click on an icon or button (preferably on the taskbar—for example near the start button) or press some control key (or for example chose such a menu option preferably in one click after opening a menu with the right mouse button)—which preferably activates the screen server instantly at that point as if the normal time for activating it has come. Similarly preferably when activating the screen saver preview from the more-steps menu on the desktop properties it preferably starts immediately to behave completely as if the screen saver as been normally activated, preferably with guarantees and improvements as explained above and below. Similarly, in the prior art Windows for example if external screen savers are installed and for example their files are damaged or they stop working for some other reason, then the OS does not revert automatically to the normal screen saver and no screen save works. So preferably in any case of for example no user activity of more than N minutes (for example 10 minutes or other reasonable period) and preferably for example at least if no video is currently running (preferably for example in full-screen mode or at least on most of the screen), preferably the OS automatically activates at least the last internal screen saver which was previously used by the user or for example some standard screen saver, such as for example the moving Windows Logo. Another possible variation is that if a screen saver includes parts that don&#39;t move for example for more than a certain period (for example a waterfall screen saver where only part of the scenery moves and part remains stationary) preferably the system detects this automatically and can for example generate the movement or change automatically, for example by starting to shift the entire image randomly and/or for example creating automatically various ripple effects and/or for example automatically shrinking the size of the image and moving it around a preferably black screen. Another possible variation is that for example if the system senses that the screen saver is too bright at least in general or in parts of it the system can for example automatically dim it further, for example after a longer period of inactivity has passed, thus creating for example an automatic 2 nd  stage lower activity period (and/or the user can at least within certain limits choose the time till this 2 nd  stage will be automatically activated). In addition, preferably the OS checks and makes sure that the screen saver has indeed been activated after the appropriate time, because sometimes a malfunction can cause it not to start even though it is defined as enabled, or for example some program displays on the screen a message which stops the screen saver and/or any program stops the screen saver in another way, and if for example this happens (i.e. for example the message or something else stops the screen saver wile running or prevents it from even starting) then preferably the OS (or some other application, which can be for example a separate application or for example at least part of the Screen saver itself) preferably takes over and for example re-activates the screen saver automatically after a certain time if there is no user activity (for example after a few minutes or less) or even for example immediately or temporarily suppresses the message until the user types something on the keyboard or moves the mouse, since there is no point in displaying the message anyway if there in no user around, or for example the screen saver or the OS lets the message reappear every once in a while, for example every 15 minutes for 1 minute, or other reasonable time, and/or for example the screensaver or the OS causes the message itself to start floating around for example together with the normal moving part of the screen saver or instead of it). (Of course if the message is for example some security warning then this means that preferably the suspect activity remains blocked until the user returns). For this preferably the screen saver or at least some part of it and/or for example the monitoring element is preferably installed at the kernel level and preferably at least lower than most other applications and drivers or even below the OS itself. Similarly, for example even if a blue screen appears with a fatal error and the user is away, preferably there is at least one function at a lower level of the kernel or below the OS which can activate the screen saver automatically anyway, for example after 5 minutes or the normal time which the user set for Screen saver activation. Another possible variation is that if it is indeed a fatal error, which typically requires a reboot, and the user is away, then preferably the system (or at least one function which works preferably at low levels of the kernel or even below it) preferably automatically activates a reboot, and preferably before that also creates automatically some log and/or other mark, so that upon reboot preferably when the user comes back a message can preferably be automatically displayed which informs the user about what happened and can preferably point him also to a more exact log and/or even automatic memory dump. (This preferably is combined with the features described elsewhere in this application—of automatically logging in back to the last user after the reboot, and/or preferably reopening automatically at least some of the applications that were running before the reboot. (Of course what matters is the principle, even if for example the message about a fatal error, which typically requires reboot, is displayed in a way other than for example the typical Microsoft full blue screen). However, if the problem is for example a hardware problem which could damage the computer, such as for example overheating or some other serious hardware malfunction, then preferably the system, instead of rebooting, preferably automatically turns off the computer (preferably also after first creating the automatic message and/or log that will be shown to the user after the next boot. Another possible variation is that if this is a fatal error of a type that does not require reboot (i.e. at least some services or applications can keep running safely until the user returns) then preferably the fatal error message is repressed if the user is away and the system preferably continues functioning and preferably displays the fatal error message when the user returns. Preferably similar principles can be applied for example when the system is supposed to enter for example sleep mode and/or hibernate after a certain period. However, another problem is that for example while the user is working normally for example the taskbar typically remains at the same position all the time, so the area of the taskbar or parts of it can become burned-in anyway since it remains with the same image for many hour each day. So preferably in order to prevent this the OS (or some other application) preferably for example automatically for example moves the entire display or at least the relevant area (for example the area of the taskbar or for example parts of it or for example the icons in it) for example 1-2 or up to a few pixels up, down, right and/or left automatically for example every 10 minutes or every hour (or other convenient interval), preferably without deviation for example more than 2-3 pixels from the user&#39;s current settings in each direction and preferably in each jump the jump (of preferably the entire screen) is only a step of 1 pixel in the new direction, so that the user will almost never even notice this. Another possible variation is that for example the OS automatically keeps a record of the screen areas that haven&#39;t changed for a long time and then for example when the screen saver is activated for example automatically displays at least for certain intervals the reverse image on those areas, so that for example in the area of the taskbar a color-negative of the taskbar is displayed for example at least part of the time while the screen saver is running, in order to correct for some of the effects. Another possible variation is that preferably the OS for example always makes sure that the CPU does not exceed a certain temperature threshold) (which can preferably be easily changed by the user) and preferably alerts the user if the threshold is exceeded, since for example some users don&#39;t install a temperature probe or sometimes eventhough it is installed it becomes de-activated by mistake or because of some runtime error. This is preferably done by the OS or a relevant application or driver which checks the CPU&#39;s temperature, and preferably the OS automatically ensures all the time or at least at short intervals that this is functioning properly and indeed reads the temperature from the CPU. Another possible variation is that preferably when the user asks Windows to create a restoration point, the user has a choice of indicating if he/she wants a normal restoration point or also creating a full snapshot of the main system and registry files and/or the user for example can define in general if and/or when snapshot or normal restoration point will be generated when the system automatically creates them (for example every certain periods and/or for example depending on the amount of accumulated changes) and/or for example the system automatically creates the snapshot files whenever it is about to make highly significant changes for example in the system. In addition, preferably rollback info is saved automatically in more than one place, preferably together with a copy of a sufficient reference base-point, so that the system has a much better chance of restoring it even if for example the registry becomes seriously damaged. In addition, preferably the registry entries are made independent of each other so that even if part of the registry is damaged it will not effect anything else, and preferably the system uses transaction sequences in the registry and/or for example other important system files (and/or for example for any file on the system or for example for writing in any sector on the disk) like in a normal database with automatic rollback in case the transaction has not been completed, so that if for example the system gets stuck while trying to update the registry and/or for example other important system files or the for example the FAT, etc., then when discovering this or for example even in the next boot (if the system for example crashed and had to be rebooted), preferably first of all at least some process comes into action which automatically finds out transactions that do not have the mark that they were completed and thus preferably activates automatic rollback to the previous state before the unfinished transaction or transactions begun, or for example if there is sufficient information about the intended transaction, this can be used to complete it. (And, as explained above, preferably the rollback info is saved in more than one places). Preferably this process or at least part of it is below the OS, since some aborted changes might for example make the OS unable to function properly until the rollback is done. Preferably such transactions are also used for example in order to enable also a much faster scandisk, since normally (unless the user for example requests a special scandisk) these transactions make it unnecessary to run any scandisk beyond searching for unfinished transactions. Another possible variation is that even if for example rollback or completion of incomplete transaction is not yet implemented, preferably at least the OS implements flags for the beginning and end of disk write operations (at least for example at the level of writing to a specific sector and/or if a corresponding update of the FAT in also needed then preferably the end flag is set only after the FAT has also been updated), so that preferably only if some writing operation was indeed stopped in the middle (for example due to the system getting stuck and the user having to pres Reset) then scandisk is automatically suggested during the next boot. (This is much better than the prior art since for example in Windows XP any reset causes the System to prompt the user to allow scandisk during the next boot even if the reset was not done in the middle of any disk writing operation). In addition, if for example there was still some damage beyond repair and the system needs for example to load a previous snapshot of the registry and/or other critical system files, preferably during boot (preferably already at the level of the boot options menu, where the user can typically choose for example safe mode, or immediately afterwards, or even before—for example at the boot selector stage) the user is advised of the situation and can automatically view for example a list of the most recent snapshots and/or otherwise possible restoration points (preferably including dates and/or other comments or information) and can simply choose the most preferred ones to attempt and then the system preferably restores it automatically and continues to boot (instead of the prior art where for example in windows XP if the registry is damaged the system sometimes cannot boot at and all the user might have to boot from a special CD and restore manually the snapshot files from their hidden directory—which is quite a cumbersome process to perform manually). Another possible variation is that preferably at least the registry (and preferably also other files that are needed for snapshots) are always automatically kept in at least two copies so that if for example one copy becomes unusable (for example as a result of crashing or reboot in the middle of updating the registry) there is always an immediate backup of the most up to date version (for example in a way similar to the way that there are always two copies of the FAT). Of course automatic rollback info and preferably transactions info can preferably be saved also for much larger changes including for example any changes to the disk, as explained elsewhere in this application. Another possible variation is that for example during preferably every boot (which is typically a time when the user has to stair at an almost blank screen for at least 20-30 seconds), preferably the system uses this time to display important information to the user, such as for example details about the number of safe restoration points and/or snapshots that currently exist (and preferably also their dates) and/or for example various indicators of the health of the system and/or for example the current automatic back-up policy that exists and/or for example the amount of remaining free space on the disk and/or for example the percent of disk fragmentation, etc. The rollback log means of course that for example even if the user for example deletes by mistake for example a large number of files or even all the files in a directory, for example by using a command with wild cards for example in a DOS or cmd window, preferably this is undoable preferably instantly, for example by simply rolling back this change, which means that the rollback for example can automatically restore the directory entries to their state before the deletion, and/or even restore for example files that have been overwritten in the meantime, if a full rollback log is used, as explained elsewhere in this application. This is much faster than for example various undelete programs in which the user would have to search for and undelete individual files. Another possible variation is that for example whenever the user tries to delete one or more files or at least for example when using wild cards, preferably for example the OS or the security system automatically asks for confirmation, and/or for example indicates in advance for example how many files (or for example what percent of the files in the directory) will be deleted if the command is allowed to proceed, and/or for example at least backs up automatically at least the directory entries or includes them in a rollback log before the deletion so that if the user makes a mistake he/she can preferably roll back or undo the deletion preferably instantly, preferably with a single command (such as for example even ̂Z). Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention.   35. Another possible variation is that for example if the user does not find a certain file name, the OS automatically checks for similar names and asks the user for example “did you mean . . . ”—for example in a way similar to the way that Google offers users to correct typing errors in the search keywords, and/or for example the OS shows the user the list of closest file names and/or paths available, sorted by closeness (for example in the dialogue box for opening files and/or for example in cmd or DOS windows). For improving the efficiency and the hit rate of the closest names offered preferably information about the recency and/or frequency of the user&#39;s accessing file names and/or directory names is preferably automatically kept, and preferably automatically taken into account when offering the most likely names which the user probably intended.   36. Another preferable improvement is that if there are more than one CD and/or DVD installed on the same computer they can be connected to a common audio connector for example in parallel or with some multiplexor (so that for example the same audio cable can lead from more than one drive to the sound card), or for example cables from more than one drive can lead to a common connector or multiplexor near or at the sound card. Preferably if more than one drive is playing for example a CD or a movie at the same time then either all the sounds are automatically routed to the speakers (this is no problem since normally the user would not play both drives simultaneously) or for example the correct drive can be chosen by software. This is better than the prior art where the user can typically connect only one of the drives to the sound card and thus can for example hear CDs or watch DVDs with sound only through that drive. Another possible variation is that no direct connection to the sound card is needed from any of the drives, and for example each CD or DVD that contains sound is simply played by activating the sound card directly through the software that plays the data, for example in the same way that the sound is played from an avi file on the hard disk.   37. Another preferable improvement is that preferably the user can for example define for example drives and/or directories to become shared for example only when connected by cross-linked Ethernet cable between two computers so that preferably for example they become automatically not shared when connected by normal cable to the internet. Another preferable improvement is that preferably the user can for example create a copy of the OS on another partition (for example on the same disk and/or even for example on a different physical disk in the same computer) preferably with a single automatic command, and then preferably the system with all the installed programs is automatically copied to the new partition (preferably by using automatically the registry to locate all installed applications and/or drivers and/or other relevant components) and preferably all the drive letter references in the new installation are automatically updated to refer to the new drive letter, and preferably the choice of the new partition is preferably automatically added to a boot selector. In this and/or in other variations preferably the user can also change the name of a boot option and/or add comments to it preferably also while booting, for example by right clicking on the desired line and then choosing from a menu and/or editing it (this means of course that preferably the mouse driver is loaded already at this stage) and/or for example by using various keys such as for example the arrows. This can be very useful if the user for example wants to create a backup of the installed OS on more than one partition, so that for example if the OS becomes corrupted or unstable, the user can in the meantime boot and work normally from the other partition. Preferably the user can do this also for additional partitions, and preferably the user can also use an update or synchronize command, which for example automatically updates any differences between two or more such OS-installed partitions or for example between any two drives or partitions or directories, so that for example the user can update the other partition according to additional changes made in the original partitions, and/or for example the opposite—automatically correct the original partition according to one of the backup partitions, etc. Another possible variation is that the user can also request for example automatic constant synchronization for example between two or more drives or partitions or directories (for example on the same computers and/or for example between different computers on a networks), so that preferably for example whenever the user writes to one of them through any application preferably the OS automatically copies it also to the other or others. This is preferably done for example by the OS preferably monitoring for example all disk access activities to the relevant drives or partitions or directories in real time, or for example the OS checks the relevant directories for example once in a while (for example every few minutes) to see if anything needs updating. This can be similar to using a RAID drive except that preferably it can be used very flexibly for example only for a specific partition or partitions or even for example one or a few directories, and so the disk drive that is used as constantly automatically preferably instantly updated backup can preferably still be used also for many other things. Preferably the user can also request automatic undo of such updates, for example if anything goes wrong (for this preferably the system automatically keeps a backup of at least the registry and other important system files and/or a preferably more complete rollback log). Another possible variation is that for example if the user adds hard disks with pre-existing data to a RAID configuration, preferably the RAID controller and/or for example the OS is preferably able first of all to automatically merge any data from the added disks, preferably by creating a merging of all the directories from the different disks into the unified drive or drives, preferably with user verification when needed, so that for example if the same directory name appears on two newly added disks that become part of the same logical volume, preferably the user is asked for example to rename one of the directories and/or for example the system suggests automatically to add to it for example one or more digits or letters for example at the end of the directory name. Another possible variation is that preferably the user can, preferably easily, change the delay time which the system waits in the boot selector before activating the default boot choice, so that for example the system waits only 10 seconds instead of 30 (preferably the user can change this for example from the boot menu itself (for example by clicking on the right mouse button and opening a menu) or for example from within one or more of the OS&#39;s, for example through the control panel. Another possible variation is that even the new partition itself can be automatically created by the special copy command, if needed, for example in a way similar to the way that the Partition Magic software creates new partitions, so that the user does not even need to have a new partition ready before requesting the special OS-copy command. Of course this can work for example in combination with systems like Intel&#39;s Vanderpool, so that for example the other installations can automatically be configured to run in parallel at the same time. Another problem is that for example applications that enable cloning or ghosting of a partition into another partition, such as for example DrvClonerXP, create also the same amount of reported free space, so that if the target partition is bigger than the source partition, it behaves as if the size of the new partition was reduced. So preferably by default and/or at least as one of the options, after the copying preferably the cloning utility or for example the OS can automatically correct the reported free space to reflect the correct size of the new partition, so that preferably this is done during the copying or immediately at its end, so that preferably when the copy is complete preferably the correct size is preferably immediately visible. Similarly, preferably this automatic correction of the free space can be used also as one of the possible variations for the fast distribution of OS images on multiple computers as explained elsewhere in this application—which has the advantage if exact tracks and sectors are cloned then as this can be considerably faster than copying a more abstract image, and this automatic correction enables it to be used on drives and/or partitions of different sizes. As described for example in U.S. application Ser. Nos. 10/301,575 and 10/644,841 by the present inventor, another possible variation is that multiple instances of the OS are preferably managed by Copy-on-Write. Another possible variation is the user can for example mark only one or more specific installed programs and/or drivers and/or other parts to be automatically copied to the other partition, instead of for example automatic full copy of all the installed elements into the other partition. Another possible variation is that the user can preferably automatically backup one or more installed programs to a back-up media, so that preferably automatically the relevant registry entry is copied to the backup media and preferably all the relevant components are automatically copied preferably through the relevant registry information. Another preferable variation is that preferably when activating for example a command like SFC (which checks the integrity of installed system files and/or compares them to their source on the installation CD and restores them when needed), preferably this or similar commands can be used also from another OS or another installation of the OS on another partition and/or for example from the installation CD or DVD itself. This is much better than the prior art, since in the prior art it is possible to run SFC only after booting into the OS whose files need to be checked, whereas OS might be too damaged to boot into, which is like catch  22 . Running such commands while booting from another partition should be no problem since the application that performs it preferably merely has to know on which partition and/or basic directory to run the checks, and preferably can use any information from there to know which files to look for and where. Another problem for example with functions like SFC (or for example when reinstalling windows from the CD or DVD) is that since for example in Windows users typically have to patch system files with multiple security patches every month, comparing system files for example to the installation CD or DVD becomes very problematic since many times files will be different because they were patched. So in order to solve this preferably when patches are applied preferably the OS automatically creates also a log of all the changes, preferably including a preferably encrypted reference copy of the patch and/or at least CRC information, and preferably also a cumulative list of all the system files that were patched and of course preferably a copy of the patch files themselves, so that when system files are checked for example with a function like SFC or similar functions, preferably files that were patched are preferably automatically compared to what they should be (preferably according to the automatic patch logs) instead of being compared to their original version for example on the installation CD or DVD. Similarly, if the user for example has to reinstall Windows form a CD or DVD for example over the same install directory in order to fix windows problems (for example without deleting existing installed programs or even in a clean new install), and/or for example even in a new partitions as an additional instance of the OS, preferably during the installation or upon completion preferably there is at least one OS process which runs and preferably automatically re-applies preferably all the patches according to the patch log, preferably by running again all the patches (which are preferably automatically saved for example at the same directory with together the log file, preferably at the same time that they are downloaded for the original patching), or for example during the normal patching updated install files are automatically created for example on a special directory so if the user needs to reinstall the OS preferably he/she can preferably directly reinstall the patched files from that directory instead of forest installing the basic OS and then applying the patches again. Another possible variation is that preferably for example when the OS displays the message that patches are ready for the user&#39;s computer preferably it indicates in advance for example if and how many of them are critical, for example by displaying the numbers in two or more categories and/or for example with using different colors, and preferably the message contains already the list of recent patches, or for example at least the list of critical patches, and/or preferably the list of available patches already in this massage preferably also takes into account for example the existing programs and/or patches, preferably from the preferably instantly available file, as explained elsewhere in this application. Another possible variation is if the user for example is installing a large number of patches (for example installing windows XP today on a new partition typically means that the user needs to install more than 80 cumulative patches from the Microsoft update site) or for example during a new OS installation and for example the user is away during the process and the system needs to ask the user for example various interactive questions, preferably if no reply is received within a certain time (for example a few minutes) and/or there are other indications of user inactivity, preferably the system automatically moves the activities that need user interaction or confirmation to the end and preferably proceeds with everything that it can. So that when the user comes back preferably the things that needed interaction can be completed in a short time since everything else is preferably already complete. Another possible variation is that for example if the OS gets stuck during or after the boot, preferably the system can automatically sense it for example after a short time and preferably for example automatically identify the driver or application that caused it to get stuck (and/or for example any other source of the problem, such as for example bad change in the registry or other critical files) and preferably can automatically roll-back to the state it was in before the problematic driver or application was loaded and/or before the registry change or other relevant change and preferably can automatically continue without the problematic driver or application and/or can for example automatically search for a replacement driver or application and/or automatically instruct the user what to do in order to fix the problem. This is preferably done by at least part of the OS which preferably runs below the normal OS and which preferably contains also a preferably large knowledge base about preferably almost any known problem that can occur, preferably with instructions on how to solve it. In addition, preferably the OS or part of it and/or for example this part below the OS preferably automatically tries to follow those self-repairing instructions whenever possible and preferably involves the user only if for some reason it is unable to perform whatever is necessary (for example because the installation CD is not in the drive).   38. Another problem which exists for example in windows XP is that for example if the user changes motherboards, the OS, unlike for example windows 98, is many times unable to overcome it and has to be reinstalled. So preferably this is solved by allowing at least part of the kernel and/or part of the OS, which is preferably hardware independent, to always boot properly even if there are a lot of hardware changes, so that preferably any adjustment problems can then be fixed after this initial boot, preferably automatically.   39. Another problem is that sometimes for example the OS does not allow the user to access a file for example at all or allows access only for reading because it is locked by another process (for example if Word previously crashed while working on a file and the user restarts Word and tries to access the file), but the user cannot do anything except open the file for example only for reading, since the OS does not even tell him/her what the problem is. So preferably when this happens (in such cases and/or in other cases of resource clashing) preferably the OS also lets the user know the identity of the clashing process and preferably the clashed resource and preferably any other needed info, and preferably allows the user also options such as for example terminating the clashing process or for example freezing it temporarily for example until the user releases again the problematic resource, and/or for example at least in cases of a file being locked for example because the application that used it (for example Word) crashed, preferably the OS automatically removes the lock that was created by the crashed application (for example after a few seconds or less or more or other reasonable interval or for example automatically when another application, such as for example the newly opened Word needs the file and the OS for example sees that the process which previously locked the file is already dead anyway), especially if it was already closed because of the crash, and/or preferably at least in such cases for example when the user tries to reopen the file the OS or the relevant application preferably automatically offers the user the option to kill the previous lock on it, and/or for example there is a general command which the user can activate for example which automatically removes locks from preferably all the files in which the application that locked them has crashed, or for example for specific files or applications.   40. Another preferable improvement is that when there is more than one physical hard disk on the same computer and more than one partition on at least some of these disks, preferably the OS automatically adds some mark to each drive name that indicates to which physical hard disk it belongs (for example an additional letter and/or number and/or icon which indicates the physical disk, for example in the explorer and/or in cmd mode), since otherwise the automatic letters given to the various partitions can be confusing and the user might loose track of which partition belongs to which physical disk. Another possible variation is that for example there can be more partitions than there are letters and/or for example partitions and/or drives can be identified also by names longer than 1 letter, so that for example if the user wants to name a partition for example “c2:” or “d2:” or “dnew:” for example instead of “d:” then these longer names can preferably be used in the same ways that 1-letter name partitions can be used (such as for example “copy f:\comment\test.doc dnew:\backup\”). Another possible variation is that the user can for example define multiple synonymous names for the same partition, so that for example the same partition can be accessed by more than 1 name. Another possible variation is that the user can preferably rename or change the drive letter (or longer name of multiple letters) of a drive also for example directly from the explorer for, example by clicking on it for example with the right mouse button and choosing form a menu, or for example by entering an appropriate rename command from the cmd prompt, which is much faster and more convenient than having to go to the special disk management utility for this.   41. Another preferable variation is that when using for example a system for predicting the next channel or channels that a user is most likely to jump to next for example in digital TV broadcasts (for example cable or satellite) and/or using multiple tuners to cover a large range of channels (so that for example the last 2 seconds in the predicted or covered channels are kept in at least one buffer) so that the zapping can be instant instead of typically having to wait for up to 2 seconds for the next base frame, as covered for example in U.S. application Ser. No. 10/905,038 of Dec. 13, 2005 by the present inventor, preferably additional improvements are added to solve the problems of the decryption time and of channel mixing. The channel mixing problem is that because some channels can be statistically much more bandwidth consuming than other channels (for example action movie channels, where there are significant changes between the frames, vs. for example an interviews channel, where people sit in front of the camera with typically little change from frame to frame), typically the cable or satellite providers try to optimize statistically the allocation of digital channels on each data-stream (frequency), so that for example there are 10 frequencies with 15 digital channels carried on each frequency, but consecutive channels are many times scattered between different frequencies because of statistical considerations. Therefore, since typically the most common zapping is consecutive going up or down in the channel number, preferably the solution is avoiding the scattering, so that the channels are grouped together consecutively in the frequencies, and solving the statistical bandwidth problem by changing the number of digital channels in each frequency as needed, so that for example if the first channels contain typically movie channels, which are by nature more bandwidth consuming, then preferably the first frequency contains less channels, as needed (for example only 7 channels instead of the normal 15), and other frequencies contain a smaller or bigger number of channels depending on the overall fatness or thin-ness of the channels that are grouped into them (in terms of the average bandwidth needed by them). This may be a little less efficient than optimization by scattering (since for example putting 7 fat men in one elevator can waste a little more space than putting people of different weights in the same elevator, since with the fat people there is less flexibility for example in the last gap if you avoid bringing in a thinner channel for the last gap if it is not the next consecutive channel), but keeping the consecutive order is much more efficient for the instant zapping. (Another possible variation is for example to keep the order as explained above but use flexibly for the last gap even 1 or more non-consecutive channels, but that is less preferable). The decryption time problem is that since it takes some time to decrypt each channel from the base-frame, in order to decrypt in advance the predicted and/or covered channels which the user can next zap into (preferably into the at least one buffer), the system has to either use some table which knows in advance which channels the user is allowed to view (in most systems the user typically has only a basic subscription and pays in advance for a set of additional non-basic channels), or the system checks if the user is allowed to view a given channel only after the user has already jumped into it. The problem is that if such a table is used (which means that the set-top box finds in advance which channels the user is allowed to view and puts this information into some table in memory), then such a table in memory makes it much more easy to hack into the system and for example change this table or bypass it. On the other hand, if the set-top box is designed to check if the user is allowed to view the channel only after the user has jumped to it (thus avoiding the security risk of such a table), then enabling the instant zapping means that the system might have to allow the user to view the first 2 seconds even before checking if the user is allowed to view this channel. One possible solution is to indeed allow the user to view for example the first two seconds (or other relevant time slice) before checking his/her permission to view the channel and then blocking the channel if needed. This is still OK since the user would normally not gain much by constantly zapping for example between two channels that he/she hasn&#39;t paid for and seeing each time for example only 2 seconds or less (except if someone for example connects 2 such set-top boxes with an automatic channel switching and automatic multiplexing into the same TV). However, it should take much less than 2 second to determine if the user has a right to view that channel, so even if the system checks the permissions only after the user jumps to the channel, the data stream can preferably be blocked automatically even sooner than the for example 2 seconds and/or for example a message can be displayed on the screen for a certain minimal time period (for example for a 100 milliseconds or less) and/or for example the message covers only part of the screen so that the data stream can only be partially viewed, thus avoiding any artificial delays even if the user immediately continues to zap. Of course, if a user can hack into the system to try to steal the permissions table he might also try to steal for example the pre-captured data streams of the covered and/or predicted channels, so another possible variation is that these streams for example remain encrypted (or are re-encrypted) at the set-top box itself, but since the set-top box already has the base frames for each of them and each current frame, when the user jumps to the channel the decrypted data stream can preferably be viewed instantly (assuming instant checking of the permission) or it is decrypted automatically so the user can view it until the result of the permission check is known. Another possible solution is that for example in the covered and/or predicted channels the system automatically detects for each such channel if it is allowed or not even before the user jumps into it, and preferably does not save this info anywhere else. Another possible variation is that for example the set-top box does determine in advance which channels are allowed for the user but preferably this is not saved in a normal table but preferably for example in some scattered and encrypted manner in memory, so that preferably even the location in memory of the different cells of this table preferably changes all the time. Another possible variation is that similarly the decrypted data of the covered or predicted channels is scattered in memory in a way that makes it very hard to hack into it, but the set-top box itself can preferably still extract the stream instantly or almost instantly. In case the set-top box can for example work also (in addition or instead) with streaming data from the Internet (for example IP set-top-box) of course the same principles apply, however there are some different problems, since for example there is typically no constant data sent to all subscribers automatically at the same time, which means that requesting the predicted next channel or channels while the user is viewing a given channel actually can put more load on the system (eventhough preferably identical packets going to the same general area are preferably sent with a single copy to each general area and are preferably replicated into multiple copies locally, as explained in other applications by the present inventor). In order to solve this, preferably the system can use additional heuristics for improving the efficiency, such as for example activating the pre-loading of the predicted next channel or channels for example only when the user holds the remote control in his/her hand, which is much more efficient, since for example if the user is watching a specific movie or program and does not hold the remote in his/her hand then obviously no zapping is occurring and thus the data from the next predicted channel or channels is not needed, and on the other hand if the user picks up the remote, typically it will take him/her more than 2 seconds since first touching it until actually starting to zap, so that this should be quite sufficient for the system to start getting the streams of the predicted next channel or channels only then. For this preferably the remote control has for example galvanic response sensors and/or other preferably biometric sensors so that preferably the instant the remote is touched it preferably sends automatically a command to the set-top-box to start retrieving the predicted next channel or channels (for example the full resolution data stream and/or for example initially a lower resolution stream or streams with preferably more frequent base frames). If the lower resolution stream is based for example on a few streams with different pixels and a phase shift in the temporal position of the base frame, these can be for example separate low resolution streams or for example different data sections in the same low resolution stream. If for example the user watches for example a TV station or for example some other form of multiple channel broadcast on the internet directly on his/her computer without a set-top box (for example directly though the Internet browser or some other application), similar heuristics can be applied for example to the mouse, so that for example the systems preferably starts fetching data for the predicted next channel or channels (for example the full-resolution stream and/or for example initially one or more streams of lower resolution with shorter-interval base frames) only when the user starts moving the mouse, since typically, again, if the user is not touching the mouse, no zapping is occurring, and if the user starts moving the mouse, typically it will take him/her more than 2 seconds till he/she actually clicks for example on some menu option in order to request for example the next channel or the previous channel or for example some other channel. Another possible variation (which can be used both in normal and in internet set-top boxes) for further improving the likelihood of correct guessing of the next channel is that for example the remote control can preferably also sense for example the position of the user&#39;s fingers before he/she actually presses a button—so for example by adding galvanic skin sensors and/or other touch sensors also to the buttons, for example if the remote senses that the user&#39;s finger is on or near the plus part of the main zapping button the chance is much higher that the user will next zap to the next channel and for example if the user&#39;s finger is on or near the minus part of the main zapping button then the highest chance is that the user will next zap to the previous channel and/or for example putting the finger on or near digit buttons can predict specific channels (for example in combination with that user&#39;s statistics and/or typical sequences). (Of course these methods can be used for example with streaming video and/or with streaming audio, such as for example with a digital satellite radio or for example with an application for example on the user&#39;s computer that connects for example to a large number of Internet radio stations or for example Internet TV stations, and/or for example with palm devices or cellular phones which can receive for example TV and/or radio broadcasts for example through the Internet or for example other cellular broadcasts). In addition, preferably the set-top box comes with extra memory fro time-slices buffer of buffers, so that if for example, as explained above, identical packets going to the same general area are preferably sent with a single copy to each general area and are preferably replicated into multiple copies locally, for example when requesting streaming data from the internet or for example when ordering programs or films in VOD (for example through the Internet or directly from the cable or satellite company)—preferably the extra-memory can work like in a computer, so that if for example a 100 users in the same general area request a certain program or movie at about the same time, preferably for example requests that are made within a small threshold (for example within the same 20 seconds window or any other reasonable threshold) are preferably grouped together and the data is sent to them at the same time so that these people view it at the same real time, and for example if the threshold is bigger—for example up to another 20 seconds a few minutes or more (or other reasonable threshold) preferably the first dozens of seconds or few minutes are sent separately (or also as united packets but for a smaller group) to the people that joined later and the rest preferably is sent to them together with the earlier group or groups, and so, provided that the set-to-box has enough buffer memory for the additional slice of the show, the next group of people can after a short delay of for example 10 or 20 seconds) start viewing the same show without further delaying the previous people, while still getting the data for most of the program together with the previous group or groups. Thus if for example a 100 people request the same show within the first for example 20 seconds window and then for example another 80 people in the same general area request the same show for example within the next 20 seconds, and assuming that for example it takes about 10 seconds to send the 20 seconds slice of the requested program or movie, then preferably the set-top-box&#39;s buffer starts receiving at the same time for example both the missing first 20 seconds (preferably together with the other 79 people of the 2 nd  group in this example) and at the same time also the streaming data which the previous group of 100 people is receiving in our example, and then the set-top box for example after these 10 seconds (with the aid of the buffer which keeps that for example 20 seconds slice of the program or movie on with a constant shift of 10 seconds from the first group of 100, with these example parameters. Another possible variation, in addition or instead, is to use for example a local area cache or proxy—for example in the connection box in the neighborhood that typically serves for example 2000 people in Cable TV networks. However, since this local cache typically has only limited space and might not have sufficient memory for holding whole programs or movies, especially if more example many different programs or movies are being requested on VOD at the same time, preferably the local cache can for example hold slices, which can be utilized for example by methods similar to those described above. Another possible variation is that when the user downloads for example Streaming Video from the internet (such as for example movie trailers or other types of video date) preferably instead of asking the user about the speed of his/her connection (which can be unreliable since the user can reply wrongly or for example the actual bandwidth can be for example lower than the official definition which the user has), preferably for example the site and/or the user&#39;s browser measures automatically the actual speed (for example by automatically downloading packets of various sizes and measuring automatically the speed) and so preferably the optimal resolution and/or for example frame rate is preferably automatically determined according to these measurements, and this way for example if the streaming data is available for download at various resolutions and/or frame rates preferably the best mode is automatically chosen if the user wants to view it not instantly (if the user can and prefers to download it for later viewing then of course preferably the user himself chooses the desired resolution and/or frame rate preferably from the available choices). Another possible variation is that for example, in addition to or instead of predicting in advance the channels that the user is most likely next going to zap to, the system can for example request and get from the supplier (or for example web site in case of IPTV) a special base frame which represents the current position in time, and a special set of changes that lead to the next normal base frame, or for example a complete set of base frames up to the point of the next normal base frame, however this solution has efficiency problems and might be relevant only when the Internet and the service&#39;s computers become more powerful. Another possible variation is that for example real-time automatic rating data are transmitted to users&#39; homes for example from the cable or satellite content provider together with the programs, preferably for each channel and program for which this information is available, so that for example pressing some key on the remote control preferably shows this data for example on some corner of the screen, for example near the channel Logo (which is typically on the top right or top left corner). Another possible variation is that for example automatic rating measurements can be made by simply improving for example the remote control and/or the set-top-box, so that for example the set-top box senses automatically if the TV is on of off (for example by sensing the electromagnetic radiation from the TV (since almost always the set-top box is on top of the TV or at least very close to it), and thus it can return automatic preferably anonymous data about the current channel being watched. This way for example the cable or satellite company can have real-time rating data from almost all of the subscribers instead of having to rely on a small selected group of volunteers (who typically also get paid for this) who have to use a special “people-meter” device. But since many times the rating measurers are also interested in knowing which family members are watching each show, preferably the remote control is improved to include for example automatic biometric measurements which can automatically identify the family member which last held it—without having to press a special button as is done with “people-meters”, which is a bother to the volunteers and is also unreliable in case they forget or are too lazy to activate it. This biometric detection can be done for example by optical sensors which can identify fingerprint and/or for example galvanic skein resistance detectors, however such methods are preferably used only with volunteers who agree to have the special remote control and who identify the age and sex and/or other data about each family member. Another possible variation is that for example a special camera is added to the set-top box which transmits data preferably to the set-top box&#39;s normal CPU or for example special additional CPU or DSP which can preferably automatically identify for example the age and/or sex of the people seating in front of it (preferably by using for example various heuristics, such as for example the height of the person as the age indicator and the hair style and/or cloths as the sex indicator), and preferably no data is transferred to the suppliers except anonymous data about the sex and/or age and/or number of people watching and which channel they are watching. This computerized camera is preferably used, again, only in a selected group of volunteers, but as explained above it can be much more reliable than having to rely on the volunteers to press some button every time the watch something. Another possible variation is that for example the methods of digital compression are improved so that a base frame can be efficiently sent more often and/or each given frame is less dependent on the base frame, and/or for example the base frame is simply sent more often even at the expense of some more bandwidth, and/or for example the sound is sent independently at the same time so that it can be played almost immediately (for example by using uncompressed sound or sound with more frequent base frames), and/or for example a lower resolution stream with more frequent base frames is similarly sent independently at the same time for example in parallel to the normal stream and can be used before the normal stream base frame becomes available. Another possible variation of this is that for example the data is split into several lower resolution streams which complement each other—for example each 1 of 4 (or another convenient number of) pixels is sent in a different stream and the base frames of each stream are preferably sent at a time shift compared to the other streams (for example ¼ seconds apart instead of for example 1 seconds apart between base frames in a normal data stream), so that a base frame for one of the streams arrives for example in ¼ of the time and then the data can be used already to create first an image in which only for example 1 in 4 pixels is known—i.e. an image of 4 times lower-than-normal resolution which can be shown 4 times sooner, and then for example as the base frame of the 2 nd  stream comes in the resolution jumps to half, and then for example ¾ and then full resolution after the base frame of the last stream comes in and then the image remains in full resolution by combining the for example 4 sources of pixels in each image. However, of course this variation is less preferable since it means a less clear image for example for about a second, whereas the solutions based on predicting the newly zapped-into channels and pre-storing their streams can give instantly the full-resolution data stream when the user presses the button. Another problem is that for example in HTPC systems since the user typically has to control the computer from a few meters away and only with a remote control similar to a Video or TV remote, without a keyboard or a mouse, it is much more difficult to communicate in an efficient way, so that for example if there are thousands of songs to choose from it can become very inefficient to navigate. So preferably this is improved so that first of all for example the remote control preferably enables the user to move easily for example a mouse pointer on the TV or monitor for example by rotating a ball in the remote control, and/or for example by moving the remote control itself for example like a 3d mouse for example sideways and/or up/down (which is preferably done either for example by laser mouse technology which can preferably work also on far objects with the sensor preferably for example pointing forward and/or for example both a forward sensor and a sensor that for example looks down and/or up and/or sideways or even sensors in more than 2 directions for increasing the reliability, and/or for example by pointing the remote at the screen itself and including for example a visual sensor in the remote which can communicate with the computer for example also based on what it sees in each pixel, including for example automatic verification of the position by tracking changes or even by a manipulated change in one or more pixels generated by the computer. Secondly, preferably the user interface of the htpc enables the user to tag for example each song or video clip or music or other media elements for example according to multiple criteria, such as for example name of song or movie, names of singer or bands or actors, genre, etc., and then preferably the user interface enables searches for example based on any or more of these criteria, for example by creating automatically for the chosen criteria for example a menu of letters, preferably for example in a square table or in a circle, for example in a way similar to a pie menu, so that preferably the user needs the minimum amount of movement to reach even remote letters, and preferably after choosing a letter preferably the next set of available letters to chose from (for example in order to spell a word or the beginning of a word) preferably appears, for example around the current position of the pointer or for example in a constant area. In addition, preferably the remote contains at least some useful keys from the keyboard, such as for example Home, End, PageUp, PageDown, Control, etc, which preferably enable for example for example faster jumping in various directions on the menues. Of course various combinations of the above and other variations can also be used.   42. Another preferable improvement is that computer cases are improved so that the same case can be used either in desktop position (lying in a horizontal orientation) or as normal tower (vertical orientation), thus giving the user much more flexibility in choosing the most convenient orientation without having to buy different cases. This is preferably done by making the case strong enough to support even a large screen on top of it when used in the desktop orientation, and preferably at least the area that supports the external CD and/or DVD drives, is preferably rotate-able between two positions, preferably in 90 degrees (preferably only back and forth between the two positions—to avoid excess bending of the cables), so that preferably the user can easily choose one of these two positions, at least by screwing the part when the case is open, but even more preferably the user can for example press one or more levers or buttons and then rotate the part even when the case is closed. An example of the case with the rotating element is shown in  FIG. 7 .   43. Another problem is that for example when there is a malfunction that does not enable the computer even to start up, the prior art motherboards or processors do not explain to the user what the problem is. So preferably this is improved so that preferably for example the CPU and/or the motherboard contain a set of prerecorded messages of possible errors and/or at least some minimal auxiliary processor for speech synthesis for speaking audibly error messages, for example with an on-board minimal speaker, and preferably include sensors that can detect at least a large percent of the possible problems or at least for example for the most common possible problems, so that for example if the motherboard turns itself off because the heat sink has become detached from the CPU and the CPU becomes too hot, preferably the CPU for example sends the appropriate error code to the motherboard before turning itself off and preferably the relevant element tells the user the relevant error message as explained above, or for example if there is a problem with the memory modules or for example some short circuit in any part of the board, preferably there is at least one part which can sense this and preferably speak out the error message to the user before the motherboard turns itself off and/or the motherboard itself does not turn itself off if possible, even if for example the CPU has turned itself off. Another possible variation is that for example the power supply preferably has a digital identification of its maximum power which it can communicate to the computer and preferably can report to the computer also its actual power consumption at any given time (for example by measuring the duty cycle of its PWM), and preferably the power supply or the motherboard comes with an application which the user installs once (for example from a CD) which starts automatically during or after each boot and preferably communicates with these data from the power supply and preferably runs automatically also various aggregated statistics and so can preferably show the user the maximum supported power and the actual power consumption for example with the exact consumption and/or for example an automatic aggregate of some time window which gives a better average indication, and can preferably warn the user automatically for example if the consumption is too high and a stronger power supply is needed—before the computer reaches a critical state where the power supply might run itself off automatically or burn. Another possible variation is that for example this application can preferably also report automatically the power consumption of the main components (such as for example the CPU and/or for example individual hard disks) and/or for example automatically alert the user for example about significant sudden statistical deviations for example above the normal typical maximum peaks, which is preferably done for example by adding also an appropriate sensor on each relevant bus on the mother board (for example a hall effect sensor), and/or for example the CPU and/or the hard disk preferably have an internal sensor for their own actual power consumption and can preferably report this directly to the OS and/or to the relevant application. Another possible variation is that if the user for example has to temporarily disconnect the entire set of hard disks for example for some hardware maintenance work and then reconnects them and forgets the correct order of data cables, preferably the BIOS automatically recognizes preferably each hard disk by its unique id and/or other parameters (such as for example, size, volume number, etc.) and can then for example offer the user for example in the pre-boot menu for example an option to restore the original order of the disks as if the data cables were never changed (preferably by automatically changing the definitions of the boot sequence according to the previous logical order) or for example to keep the new order, in case for example the user intended the change of data cables order.   44. Another problem is that due to standard debug features in motherboard bridges, actually any computers that are connected to the internet, for example through a modem card or through an Ethernet card or USB, can be compromised by a hardware-based attack even below the OS, so that for example the Ethernet card can tell the north bridge and/or the south bridge to report to it any data that passes from the hard disk and/or even send directly commands to the hard disk through the bridge. Such activities can therefore bypass any software-based security system. In order to prevent this preferably at least one of the following is done:
           a. Preferably the motherboard chipset is changed so that such debug features and/or for example direct communications for example between hardware cards and the hard disk are preferably enabled only if some hardware element allows it, such as for example a jumper or a switch which has to be manually enabled by the user, and preferably the default mode is the disabled state, or for example it is not available at all. In addition, preferably the configuration can be set for example to enable such a debug feature only for example for one or more specific preferably special slots and/or one or more specific devices, and/or enforce other limitations.   b. Another possible variation is that the user can for example add a card to one of the PCI slots and/or for example add another external device (such as for example a USB device, a PCI express device, and/or other type of connection device) which preferably keeps sending, preferably constantly, commands to the bridges which can preferably for example over-ride any attempt by other devices to tell the bridge to sniff on data or to communicate directly with the hard drive and/or for example the communication channels (for example the Ethernet card and/or USB devices and/or wireless devices).   c. Another possible variation is that preferably the OS and/or a software Security System is preferably able, preferably through the OS kernel or even below it (for example by running within the hypervisor in systems that support it), to take complete control of the bridge and give it instructions that override any undesired attempts by hardware elements to sniff data and/or access directly for example the hard disk and/or for example the communication channels (for example the Ethernet card and/or USB devices and/or wireless devices). This is, again, preferably done by also changing the chipset accordingly.   d. If for example some devices need to be able to exchange data with the hard disk directly, preferably at least any command sent from the device to the hard disk can preferably be monitored and filtered for example by the OS and/or by a security system installed on the OS or below the OS for example through the hypervisor that runs below the OS&#39;s in systems that support it, so that for example the data transfer itself is not slowed down, but for example the OS and/or the security system and/or the hypervisor can control preferably what files and/or directories and/or partitions and/or physical disks can be accessed directly from the device and preferably what commands can be transmitted to the hard disk. This is, again, preferably done by also changing the chipset.   
               
 
         [0098]    Another possible variation is that since for example PCI express is planned to become hot-swap enabled and so is SATA2, preferably this is improved even further so that preferably such connectors include also power, and preferably new PC boxes will have also one or more such external connectors for example for various SATA or PCI devices (and/or similar other preferably high speed connectors), for example at the rear of the box and/or at the front, so that preferably users can for example preferably instantly swap preferably even normal hard disks in a way similar to the way that USB disks on keys can be swapped today, without having to open the box, and preferably in case of a normal hard disk the disk can preferably for example be inserted into a capsule which protects it, and preferably the OS accepts for example such swapping of disks on the fly without any problems to other operations, preferably for example by pre-assigning it available drive letters (or for example drive names of more than one letter, as explained elsewhere in this application), for example similar to CD or DVD drives which have a pre-assigned letter and can accept or remove media on the fly. 
         [0099]    Of course, various combinations of the above variations can also be used. Of course the same principles can apply also to other non-volatile storage devices, as explained also in the clarification and glossary section. 
         [0100]    Other improvements can be done for example in statistical packages, such as for example SPSS, so that for example when correlations (or other types of output) are displayed (for example on the screen and/or in printed form) for a large number of variables, preferably the user can for example instruct the system to automatically mark for him/her the most significant correlations (for example according to the significance value and/or for example according to the strength of the correlation), for example by automatically encircling them and/or for example using some special icons and/or fonts and/or colors (in other words preferably for example the font itself and/or its background is in a special color) and/or other marks (preferably they are surrounded for example by a background with the color, so that they are clearly visible also on monochrome laser printers, for example with a gray square), and/or putting them for example in a different section. (For example the other marks can also be for example 3d fonts that appear to jump out of the text or other visually conspicuous marks). The criteria for which correlations are sufficiently significant can be for example some default criteria defined by the user and/or automatically by the system, such as for example only correlations above 0.2 (or other significant cutting point or points defined for example by the user and/or by the system), and/or for example only correlations where the significance is 0.005 or less (or other reasonable cutting points defined for example by the user and/or by the system), etc., or for example the cutting points automatically and/or by user definition can preferably change dynamically according to the results, so that for example they can be automatically determined according to the number of correlations (for example if there are much more correlations in the results than preferably the cutting points become more demanding), or for example the cutting point is in addition or instead based on relative percent, so that for example the top 5% best correlations (or any other desired percentage, definable for example by the user and/or automatically by the system) are automatically marked, and/or for example some combination is used, so that for example only the top x % correlations that are also beyond a certain absolute cutting point (for example of correlation values and/or of significance) are automatically marked. In addition, since some correlations can be much less meaningful than others—for example various Pearson Corr or other correlation commands can create automatically also correlations of variables with themselves, preferably these are marked differently and/or ignored, and/or taken into account differently so that they do not distort the statistics. Another possible variation is that the user can mark for example one or more sections of the correlations results (for example with the mouse) so that these automatic marking or statistics will be run only on parts of the results (since for example some of the correlations might be known by the user to be more or less meaningful than others). Preferably, apart from marking the most important and/or meaningful correlations, the system can, in addition or instead, also report various meta-statistics, such as for example what percent of the correlations are beyond certain cutpoints (for example according to the correlation value and/or the significance), and preferably this can be for example reported for example as a combination of such cut points and/or for example for each cut point or criterion separately, and the system can preferably also report for example what is the significance of these meta-results, i.e. for example what is the chance that for example in these specific results 12.7% of the correlations have significance for example below 0.01 (or any other value), preferably while taking into consideration issues such as for example the total number of correlations, the number of cases upon which they are based, and preferably automatically ignoring all the correlations of variables with themselves and preferably also for example any other correlations that the user marked as less meaningful and/or that the system can for example automatically determine as being less meaningful. (For example variables that are defined in an overlapping way, for example because they are based on computation involving other variables, will create correlations that may be interesting but should preferably not be confused with other statistics since part of their correlation is artificial, and there should be no problem for the system to automatically identify the problematic correlations for example according to the “compute” commands that were used). Preferably these statistics can of course relate also for example directly to the marked results, so that for example the system can report what number of results was marked out of what total, what percent it is, and/or what is the chance of having such a meta-results by chance, however these meta-statistics preferably show also additional values. Another possible variation is that the system can automatically and/or by user request generate also various graphs for visually displaying these meta-statistics. Although it is possible in the prior art to run for example a cluster analysis or an Addtree or Extree analysis on a set of output correlations, this is a very specific analysis that takes as its input a matrix of correlations and uses them as distance data to derive an analysis of the way these variables are clustered as a group. In contrast, the above suggested meta-statistics can be much more general and much more flexible, and thus can deal for example also with correlations that are not in the form of a matrix of correlations of N×N variables, and preferably can analyze for example the value of the correlations themselves, as explained in the above examples, whereas for example cluster analysis or Addtree or Extree take the correlations as input without analyzing the value or significance or meaningfulness of the correlations themselves. In addition, for example analysis such as Cluster analysis, Addtree or Extree are not a substitute for looking also at the correlations themselves, and the above described markings and/or meta-statistics can help the user analyze or evaluate also the correlations themselves. Another possible variation is to improve the Extree or Addtree display of the resulting tree for example by automatic coloring of different clusters and/or sub-clusters with different colors and/or sub-colors and/or for example automatically encircling the groups (preferably the system knows the clusters and sub-clusters in the resulting tree already since the tree is typically created from the bottom up, and/or they can be identified automatically according the length of the branches). This coloring can help the user grasp the results visually faster. Preferably the user can also manually change colors or change their borders for example by dragging the border, since for example the user might decide that one or more borderline items actually belong for example to the near cluster. Another possible variation is that for example in cluster analysis (which typically shows the results for example in a two-dimensional scatter plot) clusters and/or sub-clusters are preferably automatically colored by colors and/or sub-colors). Another possible variation is that the system can for example use more than one type of mark, so that for example 2 or more levels of significance (for example according to the significance value itself and/or for example according to the strength of the correlation) are marked differently, for example more conspicuously and/or with different colors. Another possible variation is that the system can for example automatically sort the results for example according to their value and/or importance and/or significance, so that for example in the case of correlations, for example the highest correlations and/or the correlations with the highest significance values and/or some combination of the above are displayed first. (Preferably the user can request for example if to display the correlations normally or in a sorted way, and if so, sorted by which criteria or combinations of criteria, and/or the user can for example also request some combination, so that for example the results are displayed according to certain structures and the sorting is for example only within the structures). Another possible variation is that for example instead of marking correlations, for example only the relevant correlations (or other results) that fit the criteria (and/or would have been marked) are printed, thus saving paper and time. However in that case of course preferably this is accompanied by meta-statistics that refer also to the non-printed results. These automatic markings and/or meta-statistics can be applied for example for each statistical procedure or command separately or for example to the entire set of procedures or commands, for example on the same Run. Another possible variation is that the system can for example automatically correct the significance scores of the correlations, for example according to the Bonferroni correction formula, so that the significances themselves are already displayed corrected, however that is less desirable, since it means that the significance can change all the time depending on the number of tests in the same run (or set of runs), thus making it confusing and not consistent when someone wants to compare various results. Another problem for example with Pearson correlations is that 1 or more extreme values away from a main cluster of values can sometimes distort the correlation. This is preferably solved for example by allowing the user to request automatically running the tests also on preferably automatic randomly divided sub-samples, and preferably the number and/or size of the sub-samples is determined by the user and/or automatically by the system (for example according to the number of cases and/or according to the variance and/or according to other parameters). Another possible variation is that this test is run automatically by default (for example unless the user explicitly requests to suppress it) and preferably the correlations (or other statistics results) can also be for example marked differently and/or displayed in a different section if they are more stable across these sub-sample tests, and/or the results of these stability or strength tests can be for example displayed each near the corresponding correlation (for example as a number indicating the stability value). Although for example SPSS has recently added to their most recent version (Ver. 12) the ability to request tests on sub-samples (a new feature called Complex Samples which uses CSPLAN to define the sampling parameters), the CSPLAN design specification is used only by specific procedures that are defined within the Complex Samples Option, whereas according to the above suggested solution automatic analysis by random sampling is preferably automatically available and automatically activated for any statistical procedure, and as explained above, the results of this analysis can preferably be used automatically for example to mark the most important results. So preferably either the sub-sampling is done randomly and automatically by the system by using preferably automatic defaults and/or automatic rules that are preferably used to decide the most desirable sampling strategies according to various parameters of the actual data, and/or for example the user can define in addition or instead more specific parameters, for example by the above CSPLAN procedure, but preferably these definitions can then be applied automatically for example to any of the normal statistical procedures that are used for that run, and this is preferably used also for marking the best results, as explained above (and/or is taken into account for example for the sorting, so that for example correlations are sorted both by their size and/or significance and by their stability and/or for example within a certain level of strength the results are internally sorted by stability). Preferably the user can choose for example if the correlations will be sorted by absolute correlation, with negative correlations mixed with positive correlations, or for example the negative correlations appear separately, and/or for example the user can request that this sorting be done for example separately automatically for each variable, so that for example the variables appear for example in alphabetic order or by order of appearance, and for each variable the correlations are automatically sorted so that preferably the largest correlations appear first. So preferably the user can for example enter a simple list of variables, and then request for example to run a correlation of all by all, and display the results for example by automatic sorting across all variables, or for example by automatic sorting only within each variable, and/or for example by some combination, so that for example there is a sorting within each variable, but the variables themselves are automatically sorted so that for example the variables that have the highest correlations in general (for example on average or have the highest peaks) appear first. The automatic rules defined by the system can for example take into account the original sample size, and for example determine the size of sub-samples by the minimum desired absolute size of the sub-sample and/or by the minimum desired size in percentages, and/or for example by the number of correlations that are tested, etc. For example the best automatic choice might simply be to create just a division of 2, but for example create this multiple times (for example 10 times or any other desired number) with a different random cut and compare the results for stability across all random attempts. Preferably there is for example one most preferred default, and if the user is not satisfied with this he can for example choose from a few other suggested defaults or sets of rules, and if the user still does not like any of them he can add his own rules in addition or instead. Of course, a list of correlation results is just an example, and similar principles can be applied for example to other types of statistical results where multiples results are presented together. This is much more convenient than the prior art, where the user typically had to print the results and mark manually the most significant ones. Another possible variation is that the user can for example request to run various procedures (such as for example FREQUENCIES or PEARSON) also on lists of variables defined by exclusion (such as for example “ALL EXCEPT AGE”). Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. Another possible variation is that preferably the user can tell the SPSS (or other statistical packages) for example how many digits to show after the dots in various statistical results, such as for example in Pearson correlations frequencies, significance level, etc., preferably either globally or for example for each specific procedure. 
         [0101]    In addition, preferably various statistical programs that allow backwards checking, such as for example the search engine of http://search.wallstreetcity.com/wsc2/prosearch.html are preferably improved to allow the user much more flexibility in defining the backwards checks. For example, the Wallstreetcity.com search engine allows the user to test various investment strategies retroactively up to one year, in order to see which performed best. However, the user is thus limited to only a very small test period, which can be very unreliable, since if for example during 2003 the market came up from a multi-year low, strategies that work best at such periods might for example work very differently in other periods. So instead of this, preferably the user is allowed to use the retroactive test on much longer periods (such as for example up to 10 years backwards), and in addition, preferably the user can for example divide it to one or more sub-periods and see the performance for example on each sub-period, and the user can preferably define for example the exact starting point and/or ending point of each period or sub-period. In addition, in the prior art search engine the user has no control on the way the tested strategy is applied retroactively—for example are the N stocks that most fit the test criteria simply bought at the beginning of the retroactive test period (for example 12 months ago) and just held for the entire period, or for example every month the stocks are replaced if there are other stocks that now fit the criteria better, etc. So this is preferably improved so that the user can define for example exactly on which times or after every what period the stocks are again updated according to the strategy (for example every week or every month or other convenient period) and/or for example the stocks can be updated automatically (for example even once a day or even any time) when there are one or more stocks that become better according to the criteria beyond a certain minimal margin of difference. For example if there are 8 stocks that were chosen according to the strategy, anytime that one or more new stocks become for example 5% or 10% more (or any other convenient margin) better than at least one of the for example 10 or 20 original stocks (according to the chosen criteria), then the appropriate stock or stocks can be automatically switched for example anytime during the retroactive test. Preferably all of these stock swappings take into account also at least minimal required commissions, so that the end result of the simulation preferably reflects correctly the performance that would have been made after having also paid the necessary commissions in order to apply the strategy (in addition, preferably the user can specify the commission level that most correctly reflects what he would have to pay in reality if he did these swappings). Another problem is that this prior art search engine allows the user to define the past performance of the stock (which is one of the possible criteria) only in terms of performance over a defined period (for example the last 3 years or the last 5 years), which thus unnecessarily limits the user. So this is preferably improved to allow the user to define in addition or instead for example criteria such as for example choose the 10 or 20 (or any other convenient number of) stocks that performed in a certain way from the last peak (and the peak itself can be for example specified specifically by the user as for example as an exact date or for example automatically found by the system). This is important, since if for example a NASDAQ stock was at its peak in April 2000, and was for example much lower in January 1999 and in January 2001, it might be much more informative to take as a criterion for choosing stocks their performance since the last sufficiently large peak, or for example since the highest peak that existed over the chosen period (where the peak is automatically found for example in the last 3 years or 5 years or any other desired period) instead of taking as the criterion automatically the performance since the beginning of the specified period. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0102]    Other improvements can be done for example with Internet browsers and/or other programs that access the Internet, so that for example preferably the browser can request from the server also just a part of an Internet page, such as for example a certain line or for example the value near certain words or areas or fields in the page, etc. This can save a lot of time and traffic, since for example programs that want to update data from various pages and/or run for example various statistics with data from a large number of pages might need just a small part of the data in each page, and thus this can be much more efficient than having to request the whole page and then look for the desired data in it. Although there exists already a format called RSS, which allows getting only a specific area from a web page, this is an XML format that requires specific definitions in advance in the desired web page in order to enable this. On the other hand, according the above improvement, specific requests can preferably referred to web servers regarding any pages, so that for example the browser (and/or for example other programs that accesses the Internet) can request from the server for example just a certain line or lines or words or words in the page, for example defined by position (such as for example lines  20 - 22 ), and/or for example defined by content (such as for example, Bring me only lines that contain a certain search string), etc. This is very important since most web pages today are much less structured than XML pages. The server can provide this information for example by simple string search on the web page, and then sending to the browser just the relevant data instead of the desired page. This can be done for example by the server itself or for example by additional software that runs preferably together with the server, preferably on the same computer or at least on the same site or location. Another important improvement is that when uploading a file—for example when submitting a form or in any other way, preferably the browser specifically warns the user about the file name that is about to be uploaded and preferably also its path and/or its size, so that the user can know exactly what is going on, instead of the prior art in which for example when submitting a form Netscape just warns the user that data is about to be submitted, since the prior art warning is activated any time the user presses the submit button in a form and thus the user does not pay any attention to it if he/she indeed is submitting a form, and so the user can be easily fooled for example by malicious web pages if the form looks OK but a file is downloaded from the user&#39;s computer for example as a hidden variable or in any other way that the user does not notice that it is included in the form (for example invisible font color and/or size, etc.). In other words, the warning is preferably more specific about such files, instead of or in addition to the normal warning about submitting any form. (Preferably the general warning about submitting forms is not needed and the browser automatically avoids submitting anything unless the user really pressed a submit button. However this preferably includes a lexical and/or grammatical and/or semantic analysis of what is written in submit buttons, for example in normal form buttons and/or in Javascript buttons, and/or for example the browser automatically indicates to the user near each button what action pressing the button will lead to, preferably at least when the mouse is near it, before the user even presses it, or even all the time, for example near the button or superimposed on it, for example by showing the button at least partially transparent, in order to reduce the chance of the user being fooled by a misleading button). Similarly, preferably the browser can warn the user automatically for example before allowing the user to open a link if it contains for example one or more suspicious invisible windows, such as for example with invisible font colors or for example with a window size of 1 pixel etc. (preferably by parsing the page in advance, preferably without actually executing any mobile code commands). Another possible improvement (which is similar to some of the variations of the solutions to the focus grabbing problem discussed elsewhere in this application) for example in browsers is that preferably when the user types text for entering for example in some field in a form, preferably the browser and/or the OS can keep it automatically in some buffer, so that if the user starts to type before the actual form field is reached—for example in pages where on loading the page the focus goes automatically to a search line even if the user does not click on it, such as for example in various search engines, for example if the user starts typing before the page completes loading, the typing is not lost but is preferably added automatically for example by the browser or by the OS to the beginning of the input line. Another preferable improvement for example in other email sending programs (such as for example Pegasus) is that when the user tries to send for example multiple emails and some of them get for example a TCP/IP error or some other kind of error when trying to connect to the mail server, preferably the email sending program automatically saves these messages separately and can preferably automatically try to resend them for example after some time or by user request (preferably only if they are non-permanent errors) or for example can automatically display them one after the other so that the user can try to correct whatever is wrong when possible, and then for example pressing some key automatically tries to resend the same message. Another preferable improvement is that for example if the user changes the language from English to Hebrew while filling a form in a browser, preferably the user can also indicate if the change is intended only for that specific browser window, or for example the change is by default automatically only for the specific site involved until the user changes it again (which means that preferably this information is saved for example in a cookie file), or for example the change is automatically only for similar types of forms, etc. Another possible variation is that the browser automatically takes into account the language of the text near each form field and automatically accepts by default the input in the appropriate language. Of course the browser does not have to positively identify the language but at least the relevant character set and then preferably use the same character set by default for the near input field or fields. Another possible variation is that preferably when the user defines in the OS the regional supported languages, preferably instead of having to search manually for a given language, preferably the user can for example type one or more letters and the system preferably automatically finds and marks the relevant languages, so that for example if the user types ‘he’ preferably the system can find preferably instantly for example all the occurrences of Hebrew. Another possible variation is that preferably the user can for example use copy or cut and paste for values filled in forms, or example by marking sections of the form or for example by pressing ̂A to mark all, and then preferably the copied values can preferably be for example pasted into another form, for example in a different web page on the same browser, or for example for the same page in a different browser, and in that case preferably when the paste is done preferably the browser tries to automatically insert each value in the corresponding field in the from to which it is being pasted (for example by detecting similarities in the names of the fields and/or their structure or position on the form), and for example in cases of uncertainty about where one of more of the values should go preferably the browser asks the user what to do. (Preferably this can be activated for example by copy &amp; paste into the new form or for example by some browser command which requests the intelligent copy into the new form). Similarly for example in fill-able pdf forms if the user has to move data for example from one version of the form to another, preferably the user can similarly for example use copy &amp; paste or some other command in order to request the smart automatic copy of data from the fields of the old form into the matching fields of the new form. Another possible variation is that for example the user can activate a command which compares for example two pdf files and can for example make changes in the old pdf file so that it becomes like the new file without damaging or changing the already filled data which it contains, which can be equivalent in the results to the alternative above-described method of copy and paste. 
         [0103]    Another improvement in Internet browsers is that preferably the user can for example mark a group of links (for example in the history list and/or in the bookmarks list of the browser, and/or for example in any web page displayed by the browser that contains links or for example other type of file that contains multiple links) (for example in a way similar to marking more than one object in a scroll list and/or by simply marking the area where the desired links are), so that after the user for example marks the desired group or groups of links, preferably pressing for example some button (such as for example an icon on the browser or for example the right mouse button and choosing from a menu for example the option opening in new tabs) causes the browser to automatically open multiple windows or tabs so that preferably each window or tab accesses automatically one of the marked links. This means of course that preferably similarly choosing for example “save as” after marking the links causes the browser to automatically save the targets of all the marked links (for example other web pages and/or files, etc.). In this case preferably they are saved by default with their original names, or for example the user can define a group name which is preferably incremented automatically to differentiate between the files in the group, and/or for example the system can automatically read the title in each of the files or web pages and use that as the name, and/or for example the user can automatically save the group of pages one after the other in the same cumulative file (in this case preferably the browser adds automatically separators between the original pages and/or the url before each page starts in the combined file. Similarly, preferably the user can also for example perform other commands on the group of marked links, such as for example automatically print the group, etc. Another possible variation is that preferably the user can for example mark multiple email addresses (for example when some email has to be sent to a number of people with cc) and then for example by using cut &amp; paste into the recipient&#39;s field when composing a new mail message, preferably the browser (or for example other email program) automatically pastes the first email as the first recipient and the other emails as the copy recipients (for example in Netscape by automatically adding them line after line, as is done in Netscape, and in Opera by automatically adding the copy recipients all together in the second line with commas inserted between them, as is done in opera). Another possible variation is that for example if the user needs to copy &amp; paste for example a number of lines for example from one document and then enter for example each line into a different field for example in a form (for example on a web page or for example in an application such as for example the Epoline application), preferably instead of going back and forth and copying each line at the time, preferably the user can also for example copy a set of lines and then for example when pasting for example activate a control which displays the coped text for example as a floating windows from which the user can for example scroll or click to chose for example each time a different line to paste. Another possible variation is that the browser preferably allows the user for example after jumping to some bookmarked page, for example to move consecutively forward or backwards for example to the next or previous bookmarked pages consecutively (for example by clicking on some arrow or icon or for example pressing some key. This can allow the user for example to go over some recently marked faster than having to click on them one after the other without having to open multiple tabs or windows of them at the same time). Another possible variation is that when the user sends a web page by email to someone preferably the browser enables him/her also to mark for example one or more sections (for example by underline or boldface or some color, for example like a virtual yellow marker) or some other visual indicator. (Preferably the sender merely has for example to normally mark for example one or more sections for example with the dragging the mouse for example with the left button pressed, and the marking of more than one section is preferably done as explained elsewhere in this application for example by pressing dome key, such as for example Control or Shift so that the previously marked section or sections remain marked when the user marks a new section). This is preferably done for example by the browser adding automatically for example the needed html control tags near the marked area and then attaching the modified page, or for example by sending only the url and adding to it a few parameters so that when the web page is displayed the displaying browser or the server at the web address know which area or areas to mark (for example by automatically adding the marked text itself or for example the beginning of it as a parameter and/or adding for example its offsets for example in number of characters or number of words for example for the beginning and end and/or length of each marked section, and this means that the http servers and/or other browser (of the receiving user) preferably respond to this new convention accordingly), or for example the browser merely for example automatically adds the text of the marked section or sections to the beginning of the email message (for example with the caption “please pay special attention to the following text”) and then adds only the url link after the marked text. Another possible variation is that preferably after the user searches for something in a web page and the browser for example automatically marks all the occurrences of the search term in the page (for example in yellow as is done for example by the Opera browser), preferably if the user moves forwards or backwards and then return to the page that was marked, preferably the marks are automatically restored by the browser, and also preferably for example if the user closes the tab and reopens it for example by ̂Z (for this preferably the browser simply needs to remember the fact that the page was marked and the search string that was used), and/or for example if the web page is part of a series of articles so that for example near each end of the page there is a link to the next part, preferably the browser automatically marks the search words also on the next page (unless the user for example changes the search string or for example cancels it for example by pressing Esc or some other control) (in this case preferably the browser automatically identifies the series of pages as multiple parts for example by the words “part” in the link and/or for example by the consecutive names of the files on the same domain, or similar heuristics. Similarly, preferably if the user for example clicks on the page with the mouse or for example marks a section, preferably this does not cause these marks to disappear, so that preferably in order to remove the marks preferably the user has to enter an explicit command intended to remove them, such as for example pressing Esc or some other control or for example clicking on some icon or some menu option. Another possible variation is that preferably if the user tries to print a page that is marked like that preferably the marked words are automatically by default also printed as marked, or for example this is at least one of the options which the user can for example choose in some configuration menu or for example in the printing dialogue. Another problem is that for example in Opera if the web page is marked for example with yellow marks as a results of searching for something, reducing or enlarging the fonts can cause the marks to run out of their correct place. So preferably this is improved so that the marks are preferably enlarged or reduced together with the fonts which they cover and their position moves together with the marked words—for example by reducing or enlarging them together which each character or word or string which they cover, or for example by re-marking them again automatically after the reduction or enlargement, so the new marking is automatically done at the new positions of the relevant words. Another possible variation is that the browser preferably saves automatically for example in some configuration file or for example in the history list and/or for example in the bookmarks list preferably also information such as for example if the user reduced or enlarged the view for example of a file or a web page and by what factor and/or for example if the user used author mode or user mode, and preferably when the user accesses again that file or web page is preferably opened by default with the last size and/or mode which the user used the last time he/he viewed that page or file on the browser. Another problem is that if the user for example watches some video and downloads it at the same time, for example in the Opera browser (for example from video.google.com or from youtube.com), at least if the video has not already finished downloading in one of the two modes, the browser downloads the video twice (at least when downloading from video.google.com). So this is preferably improved so that the browser preferably checks automatically if it is already downloading the same video (i.e. the same file name from the same url) for example in another tab or window and, in that case preferably automatically links the new download (for example for viewing or for saving) to the same temporary file that is already being downloaded (for example for viewing or for saving). However since downloading from the above two sites is typically done for example by finding the actual download link in sites such as http://keepvideo.com or http://javimoya.com/blog/youtube_en.php, the browser might have a problem in this case to identify that this is the same video file since the link for viewing appears as a different url from the link for downloading. In order to solve this preferably the browser for example is familiar with this download helper pages and can identify the viewing url that was pasted into the page for getting the download link and then compares this url with the viewing url to find if they are the same, or for example the download helper sites are improved so that the same pasted link is used also for viewing at the same time, or for example the browser is improved so that it can find automatically the download link by itself for example the same way as these download helper sites work—for example by analyzing the viewing web page and/or capturing the actual link on the fly when requesting to view the video, and then preferably the browser offers as one of the options for example viewing and saving at the same time (this can be done for example by the browser itself or for example through some plug-in which can be used both for viewing and for saving for example at the same time), and/or for example if the temporary file that is saved for viewing is encrypted preferably the browser can decrypt and save it to a normal local file as one of the available command or options (since of course the playing routine knows how to decrypt the temporary file for playing it), or for example the browser saved the file in the unencrypted version anyway even when the user is just viewing it. Another possible variation is that preferably one or more plug-ins are used in the browser which preferably can play as many formats as possible and preferably can automatically save to a local preferably unencrypted file preferably any stream of data that passes through it. Another possible variation is that when downloading video files for example with the aid of sites such as for example such as http://keepvideo.com or http//:javimoya.com/blog/youtube_en.php, preferably the site displays near the download link (preferably already in the search results page) also for example the size of the file preferably near each result (for example in Mega Bytes), since in the prior art the user can see the size only after clicking on the download link. Another possible variation is that preferably at least some of the video formats are improved so that the video can include also one or more links which can be displayed for example while playing the video and then for example the user can click on the link with the mouse and the appropriate web page opens for example in a new tab or new window in the browser. Such links can preferably be entered for example into the same text which is normally used for sub-titles or for example some visual cue is displayed for example anywhere in the picture for example for a specified duration, and preferably such links are added after the filming by editing so preferably the url itself is directly linked in the video file format to a textual url. (When downloading a video from youtube while viewing the video in another tab apparently Opera for example does indeed start the download from the middle or even completes it instantly if the video has already been sufficiently downloaded for the viewing, so at least in youtube.com Opera does indeed identify that it is the same file, but on the other hand downloading the same video while still playing it on another tab typically causes the video viewing to stop in the middle after a short while, so apparently the above rules are not completely and consistently applied). In addition, preferably the browser saves the information about the local temporary buffer used for viewing a video file also if the user for example goes back in the tab or closes the tab, so that if the user then decides for example to reopen the tab or for example go forward again in the tab or clicks again on the link for viewing the same video file, preferably the browser uses the part of the video which was already downloaded to the local buffer and thus downloads only the missing part or does not have to download anything if the buffer already contains the full video file. (In the prior art for example Opera in such cases starts to download again the video file from scratch). A similar problem is that for example when playing video files in video.google.com, if the user jumps to another section of the file which has not been downloaded yet (by moving a horizontal lever to that position), the browser (for example Opera and Firefox) starts to buffer and play starting from the new section but loses the previous section, so if the user later goes back to the previous section the browser again starts downloading it from scratch. So preferably this is improved so that the browser keeps also the previous section—preferably for example by creating in advance a temporary file with the size of the entire video and adding the current sections at the correct place (in a way similar to the way torrent files are downloaded), and thus the previous already downloaded section is not disturbed by jumping to another section, and preferably for example after the current section finishes downloading preferably the browser automatically finishes downloading also the other sections, in case the user will want to jump back to them later. Another possible variation is that for example when searching for video files for example on http://youtube.com or on http://video.google.com or similar sites, preferably the user has more advanced search parameters or options, such as for example requesting a specific upper and/or lower time-length limit (for example in minutes and/or seconds)(although video.google.com allows choosing one of three broad time length categories or any time length, the user cannot more flexibly designate the desired time length), and/or for example the user can request to view the results sorted by time lengths (for example alone or in combination with other criteria), and/or for example the user can preferably request to see the results for example based on various specifiable weights to various parameters, such as for example the total number of viewers, the rating given by users (for example to the music itself and/or for example to the video content and/or for example to the quality of the specific file in terms of video quality and/or sound quality), the total number of viewers divided by the length of time that assed since the video was downloaded, etc. This can save a lot of time especially when the user is searching for keywords for which there are many results. Preferably such parameters are saved for example in a browser cookie so that they are kept for additional searches as default until the user decides to change them again. Another possible variation is that preferably the application of such limitations is for example automatically (or as one of the choosable options) dependent on the number of results, so that for example if there are too few results (for example 20 or less) some or most of the limitations are for example automatically removed or at least made more flexible, and/or if there are too many results for example even additional automatic filters are preferably added). This is very convenient if the user for example opened multiple tabs and wants to go over them consecutively even if in the middle he/she for example clicked on another tab for some reason. Another possible variation is that preferably the video search site (such as for example youtube.com or video.google.com or legal torrent searches) preferably displays automatically near the video files also data about their quality, such as for example the resolution and/or the bit-rate and/or for example the sampling rate of the sound and/or the size of the file for example in bytes, thus enabling the users to choose more easily the desired quality without having to waste time in viewing multiple versions of the same video. This is preferably done by the server preferably when the file is uploaded to the server and preferably the server then extracts this data from the meta-data within the video file itself (since this data is typically contained in the video file itself) and then the server preferably saves this data preferably in some small text file which is preferably linked to the video file or in some preferably instant access index, so that it can be displayed instantly together with the other information about the video file without having to extract it again from the video file each time it shows up as a search result. In addition, this automatic ranking of quality is preferably automatically converted also to one or more general quality score which is preferably not only displayed near the video file but is preferably also used automatically by the site&#39;s search engine for sorting the videos in the search results, so that preferably the order the videos show up is preferably based on a combination of user scores, numbers of times viewed, and the automatic quality measures. Another possible variation is that for example also songs and/or for example video files and/or for example pictures on the user&#39;s own computer can be (for example at least in one operation mode) automatically sorted for example according to frequency of use and/or recency of use, so that the items which the user views most frequently and/or most recently preferably show for example at the top of automatically generated one or more play lists. Another possible variation is that preferably large VOD sites are improved to work on a model which enables users to download for example an unlimited number of files per month for example for a monthly subscription (or other period and/or for example charges extra if the number of downloaded files exceeds some high limit)(such as for example 30-50$ per month) and/or based on advertisement revenues, and preferably the payment to the copyright owners is in a way similar to the radio, so that preferably eventhough the users don&#39;t pay for each song they download, the payment to the copyright owners is based on the number of downloads (and/or view), however this is preferably statistically based so that for example a certain amount of money is divided each month between the copyright owners (for example 80% of the revenues from the subscriptions and/or for example also from advertising on the site), and what changes each months is the division between the copyright owners according to the download and/or viewing statistics. This is a financial model that should at least be as efficient as for example normal commercial TV or Radio, except that the users get much more benefit since they choose completely freely what to watch and when (which also means that they will eventually spend much more time on it than on viewing traditional TV or radio channels, thus increasing for example the revenues for advertisers), and also the advertising can be more relevant than in normal TV or radio, for example by requiring the users to enter at least some demographic data (such as for example age, sex, area and education, and the users won&#39;t lie because that would mean they would get less relevant advertisements) and/or by combining this with a social network and/or dating service in which users will be interested in entering voluntarily even additional data, and/or for example by the site automatically building a preferably anonymous preferences profile of the user according to his/her viewing history and/or at least automatically choosing advertisements relevant to the video the user is currently watching, if advertising is used. Another possible variation is that preferably the user can for example mark for example any section in any tab (for example by a square or other shape in a way similar to marking an area in a drawing program, and then preferably the user can define the marked area for example as always on top and can preferably drag this area to any desired position on the screen, so that for example the user can do other activities while monitoring the specific data in the marked section (which can be for example the progress of some download or for example some realtime data from the stock market, etc.). Preferably this can be done for example by the browser itself to various tabs and/or for example done by the OS even between different applications. Another possible variation is that for example the transfers tab or page (which typically lists the recent file downloads) preferably automatically shows preferably near each downloaded file in the list also the date and/or time it was downloaded and/or at least shows this information if the user clicks on the relevant line or for example even if the user just hovers with the mouse over it. Another possible variation is that for example if the user clicks for example by mistake in the transfers tab for example on the option of “remove finished transfers” and all the finished transfers are removed from display, or for example after transfers are automatically removed for example after a certain time, preferably the user can enter a command (for example by typing ̂Z or some other control or for example by choosing some menu option) that preferably automatically undoes such removal or for example shows again transfers that have been removed from view for any reason. This means that preferably the browser keeps automatically a list of recent transfers which is preferably much larger then the displayed list, for example for a certain preferably long time period (such as for example at least a year or any other reasonable period, which preferably the user can also change) or for example until a certain number of transfers is reached in the list or for example until the list reaches a certain maximum file size limit, and preferably each item in the list contains also information such as for example the date and/or time the transfer was made and/or for example also the date and/or time it was removed form display, and preferably this information is used if the user wants for example to view transfers that have already been removed normally from display or for example undo a command which removed them suddenly, as explained above. Another possible variation is that at least if the Transfers tab is the currently forefront tab, preferably for example the browser or the OS preferably always makes sure that the remaining transfer time is shown on the square of the browser in the taskbar, so that even if there are too many squares and the square becomes small, preferably the transfer time remains in the visible area and/or even the its font size is decreased if necessary so that the user can still see it (in the prior art if the transfer tabs is in the forefront fore example the Opera browser does show the remaining transfer time, but only if the square is very large—for example when there are 4 squares in each line, but it can quickly become invisible as the squares grow smaller). Another possible variation is that preferably even if the Transfers tab is not in the forefront but there is at least one download currently in progress, preferably the remaining transfer time is automatically displayed in the square of the browser on the taskbar. Another possible variation is that preferably the remaining transfer time for downloads is shown automatically for example by the browser for example regardless of which tab the user is currently in—for example by showing it in an available space for example between the tab top and the tab handles line or for example at the bottom of the tab—preferably for example within a conspicuous border—preferably in a constant position, but preferably the user can for example drag for example the box that displays the remaining transfer time for example with the mouse also to other positions and/or for example even outside of the browser, so that it will show for example anywhere above any windows—for example in a way similar to the floating bar of the Google Desktop Search (in other words this is preferably an item that is preferably automatically offered by the browser, for example at least when the user is downloading something). Another problem is that for example when viewing videos on sites such as youtube or similar sites with the browser or when viewing for example videos with normal video viewing applications such as for example PowerDVD, the user cannot change the aspect ratio or get rid of the black elongated squares at the top and/or at the bottom (in case of widescreen ratio) unless the video is viewed at full-screen mode. So preferably this is improved so that even when viewing the video in a partial window or partial viewing area, preferably the user can change the aspect ratio and/or change the size of the visible video itself compared to the black area. In this case for example the user can preferably change the aspect ratio for example by changing the size of the window (for example in case of a video-playing application) and/or the size of the video playing area (for example in case of playing the window in a limited area within the browser) for example by pulling the corner so that the width changes more than the height or vice versa or for example by choosing the desired aspect ratio from a menu which becomes available even when not in full-screen mode. Similarly, the user can preferably get rid of the black for example by clicking on an option or on a control which automatically gets rid of it (preferably by automatically increasing the image within viewable area, preferably while keeping the same aspect ratio), or for example by clicking within the visible part of the video and for example pressing ‘+’ or for example rolling the mouse&#39;s wheel the user can preferably increase its size within the viewable area. After that, if the user is for example viewing the video in a limited viewing area in the browser, and preferably then increases or reduces for example the global size of the page, preferably the browser preserves the aspect ratio and/or the getting rid of the black elongated squares, and preferably the browser also automatically remembers these parameters for example in the bookmarks or history file so that if the user later returns to view this video again preferably the browser automatically chooses as default the aspect ratio and/or black borders ratio which the user used the last time he/she viewed it. Actually Zoom player for example does allow the user to change the aspect ratio even when not in full screen mode, but not to get rid of the black elongated squares at the top and at the bottom in case of wide-screen, and when in the normal aspect ratio, which is typically 4:3, if the user is not in full screen mode then instead the two elongated black squares on the top and on the bottom there are two such vertical black squares at the right and at the left, so preferably by requesting automatic removal of the black squares or by manually increasing the visible part of the video preferably the user can easily get rid of these squares in this mode whether vertical or horizontal. Another possible variation is that for example in the non-full screen mode preferably the video-playing software for example automatically by default increases the size of the video by the correct amount so as to get rid of the back squares automatically, or for example automatically temporarily sets the aspect ratio to a ratio between 4:3 and widescreen so that the aspect ratio is partially distorted but the video fully fills the display area without losing information, or for example uses by default an intermediate or hybrid solution in which the aspect ratio is only partially changed and the video is only partially enlarged, thus making both the slight distortion of the aspect ratio and the loss of some data at the borders minimal and not noticeable and/or for example automatically making the image taller while trimming a little the top and/or the bottom of the image (preferably in an amount that is not noticeable but thus correcting the distortion in height versus width), and/or the user can preferably for example choose one or more of the above options in a menu of possible automatic corrections or default automatic corrections. In addition, preferably when the user switches from full-screen mode to other modes (for example partial window or full window but where the taskbar is visible) or vice versa, preferably the video player automatically adjusts the aspect ratio to correspond to the last ratio which the user chose, preferably together with the automatic removal of the black elongated squares on the sides or on the bottom and top (which means preferably automatically stretching or reducing the horizontal size and/or the vertical size accordingly as needed, and preferably automatically making sure that for example subtitles will not run out of the picture, for example by automatically identifying them if they are part of the image or for example in case of separate digital subtitles, such as for example in a DVD, automatically displaying them in the appropriate size and position and/or using for example a smaller or thinner font when needed). Another possible variation is that for example if the user views in full-screen mode a film that was designed for Widescreen (for example by using the pan &amp; scan feature in Power DVD with the factor of 1.85) and/or for example when titles or credits or other textual data are shown at the beginning or the end of the movie they are cut off at the right and/or left edges of the screen, preferably the video-playing software can identify this automatically (for example by text-identifying heuristics similar to those used in some OCR programs) and can for example automatically temporarily revert to wide screen mode in those sections or can for example automatically condense the image at this section so that the text is not cut-off and no black squares appear on the to and bottom (which means that images become temporarily more thin relative to their height, which is a problem for example when looking at people but is much less of a problem when most of the screen is occupied by text), but preferably the user can of course disable this feature if he/she does not like it or can preferably for example press some control for instantly aborting the automatic change or for example vice versa—press for example some control in order to instantly activate the automatic correction (Of course if the titles or credits are digital then preferably the player automatically adjusts for example the size and/or the width of their fonts if needed instead of changing the aspect ratio of the image). Another possible variation is that preferably the video playing software is able to automatically determine the correct aspect ratio for example by various heuristics, such as for example identifying human faces and/or other known objects and determining if the faces and/or other known objects seem with proper proportions or for example seem too thin or too fat. Another possible variation is that preferably the video playing software preferably remembers the aspect ratio which the user used for watching various video files (for example by saving it in some file that is linked to each video file, or more preferably in one or more united configuration file that refers to multiple video files), and preferably uses by default the aspect ratio which the user last used when viewing the file the last time, and/or for example the aspect ratio can also be remembered for example separately for full-screen mode and for non-full-screen mode. Another possible variation is that if there is for example a problem of audio-video synch in a file, then the video-playing client software on the user&#39;s computer can for example also correct this automatically, for example by using heuristics for checking lips movement and phoneme extraction from the sound track and trying to match it automatically (preferably with additional heuristic rules such as for example assuming that the sift is no more than a certain amount of milliseconds and assuming that the shift is more or less the same over the entire video, so that the correction should feat ok on more than one section where moving lips are seen), and/or for example the server on the site (such as for example youtube) can preferably automatically correct it this way this when the file is downloaded. However, in order to avoid errors and prevent unnecessary checks, preferably the server or the client program do this only if requested explicitly by the user or if the file is marked by users as having Audio-Video synch problems (preferably the site adds an icon near displayed videos that lets the users mark if there are such problems). In addition, preferably the search engine of video sharing files, such as for example youtube, is preferably improved so that preferably automatic suggestion of corrected spelling of search words and/or for example synonyms and/or for example semantic qualifiers and/or other search engine improvements described in this application are applied also there. Another possible variation is that for example when searching for things in sites such as for example youtube one of the links in the results page is for the results of the same search string for example on the web search and/or for example on the news search, so that if the user clicks on this link it opens for example in the same tab or more preferably in a separate tab also the search results of the same search string for example in the normal Goggle web search. This can be done for example for each search or for example only if there are no results or for example less that a certain number of results. Another possible variation is that preferably similar links are created automatically for example preferably from every type of Google search to preferably at least the most important or to related other types of searches, again, for example each time or only for example if there are less than N results. Another possible variation is that for example when the user selects multiple downloaded file names for example for playback for example in cases where the same file has been cut into two or more parts, preferably the player and/or for example the file system explorer automatically sort the file names properly so that for example the section that&#39;s ends with ‘10’ appears after ‘9’ and not after ‘1’, preferably by automatically identifying digits that are part of an incrementing number and interpreting them properly so that they can be automatically sorted correctly according to their numerical value. Another possible variation is that for example when viewing such divided files on the Online site itself (for example in youtube or similar sites) preferably the user can also for example mark multiple files and activate for example an option which lets him/her automatically view them consecutively without having to witch manually to the next part each time, which can preferably be done for example with the help of the site&#39;s server or for example simply by the browser (in this case preferably the browser automatically orders the parts correctly as explained above for example if they have the same name followed by a serially increasing number, and preferably starts downloading automatically into a preferably temporary buffer each time preferably at least also 1 or two or more of the next parts in advance so that the user does not have to wait for them to download later and so that the browser can preferably automatically and preferably instantly switch on time to the next part when the user is viewing the divided file. Another possible variation is that for example when displaying the search results for example sites like youtube or similar sites preferably automatically list files which have the same name with an incrementing serial number preferably automatically in the correct numerical sorted order. 
         [0104]    Another problem is that many times the user needs to reinstall some application for some reason or to install it in another computer but does not remember where the original installation file was, which can happen especially if the user for example installs various applications from bonus CD&#39;s or DVD&#39;s which come with various computer journals. So preferably this is improved so that for example in the registry or in some installation log or for example in the directory where the application is installed preferably the OS automatically keeps also information about from where it was installed (i.e. for example path and file name if it was installed from the hard disk, and various identifying details if it wad installed for example from a CD or DVD or some other removable media) and/or preferably also an automatic copy of the installation file or files themselves, at least if they are not too big. This means that for example in the case of installing from a CD or DCD preferably the OS automatically keeps for example in the installation log or directory for example information such as for example the name of the CD or DVD, the path and name of the installation files, the date of the CD or DVD, etc., and preferably if the installation file or file are up to a certain size they are preferably copied automatically also preferably to the installation directory or for example some special subdirectory in it (preferably during the installation) and if they are bigger preferably for example the user is asked if he/she wants to copy them also automatically, and for example beyond a certain even larger size preferably the user is not even asked and the installation file or files are not copied. Another problem is that for example when uninstalling programs for example in Windows in various cases an application is not completely uninstalled and then if the user tries to reinstall it or a different version of the software he/she gets an error message that one or more things such as for example dlls or files are missing, and the installation fails. This can be vary confusing and frustrating to users because such messages are misleading since nothing is really missing and in fact in such cases typically there are just some extra traces in the registry or in other directories that should have been removed by the uninstall but for some reason were not removed. So preferably the Installer and/or uninstaller or the relevant function in the OS are improved so that for example clear logs are kept of what was added or removed and preferably where it is or was, and so preferably the messages reflect correctly if something is indeed missing or if the opposite is the case, preferably with sufficient information about where exactly the problem is, and/or preferably in such cases at least when installing the new application preferably the installer for example uses for example the information in the logs to get rid of whatever remaining trace components are causing the problem and/or for example the installer for example understands for example from the log or from analysis of the conflicting parts that nothing is missing, and/or for example regardless of any misleading messages about missing components the installer is improved to install anyway whatever it needs, even if it means for example putting it in another area, preferably with appropriate links or references to it if there is for example some conflict between installed components. Another problem is that for example the in Windows XP the OS sometimes refuses to do simple things such as for example simply copying a file within a CMD window and displays a cryptic message such as “Insufficient system resources exist to complete the requested service” without any explanation about which resources are missing and/or what is causing this and/or what can be done to remove or solve the problem. So preferably this is improved so that if there is such a problem preferably the OS explains in the message exactly which resource or resources has the problem (for example running out of special system memory, etc) and preferably tells the user what can be done to resolve it preferably without having to reboot and/or preferably for example the OS preferably automatically fixes the problem for example by allocating more memory to the system and/or or example by removing or relocating any service or application which might be causing the problem and/or for example asking the user the choose from various courses of possible actions that can solve the problem. Another problem is that for example when the user&#39;s mail box becomes full many ISP&#39;s or for example universities start automatically rejecting excess email, which means that until the user cleans up the email box he/she will lose all the new email and will usually even not know which emails were lost, which means possibly losing important information or for example losing money or rights in cases where these are important messages in which the user has to act on something with a time limit, especially if it is a short-time notice or reminder (which can be even a huge loss for example in case of losing a message about an office action of a patent which has to be replied to on a close time limit). So preferably this is improved by at least one of the following methods: 1. Sending automatically preferably repeated preferably short warnings to the user that his/her email box is almost full or is already full and emails will soon be or are already being rejected (for example to his/her normal email and/or for example IM messages and/or for example SMS), 2. For example if no other real-time solutions have been provided or have been used up, automatically starting deleting the oldest email in the mailbox and/or for example email that has already been read rather then rejecting the newest email, 3. Automatically increasing at least temporarily the size limit of the user&#39;s email box while preferably sending him/her automatic warnings about this and/or starting to charge him/her some additional amount according to the amount of extra storage needed. 4. Automatically storing for example email or excess email for example on some cheaper storage solution fro which the user can later get back his/her rejected or deleted email for example for free or for some additional preferably small charge (this can be done for example automatically by the storage system of the mail server, or for example based on some automatic forwarding of excess email to the lower cost storage server). (Solutions 3 and 4 are of course the most preferable in terms of preferably avoiding any loss or risks). 5. Starting to reject for example only large emails from above a certain size and/or for example only certain file types which are for example defined by default as less important, such as for example videos. 6. Another possible variation is that the mail server for example allows the user for example to define his/her own rules for protecting against losing email messages, such as for example defining conditional Forward rules, so that for example the user can set rules such as for example that that if the mail box becomes full and/or for example in N % full, then for example in cases where the email is from a certain address or set of addresses and/or for example is for example of a certain type or types and/or for example contains some specific text or keywords for example in the subject line and/or elsewhere it should for example automatically for example be forwarded (for example in addition or instead of keeping it also in the normal mail box) for example to some other email address or set of more than one addresses), and/or for example defining rules for example for always accepting important email, such as for example being able to list a set of for example sender email addresses and/or for example keywords in the title and/or for example in the text itself so that for example if such emails arrive they should always for example be saved in the mail box preferably at any cost and/or for example also forwarded for example to one or more additional email addresses, and/or for example also an automatic Instant Message and/or for example automatic SMS and/or for example even an automatic phone call (for example to a normal phone and/or cellular phone and/or for example IP phone, such as for example Skype) should be preferably automatically generated preferably instantly when they arrive, (and/or for example when the email box becomes full or for example almost full), and/or for example such important emails are preferably automatically marked more conspicuously by the email client, such as for example by using automatically larger fonts and/or for example boldface and/or for example special color and/or for example marking around them with yellow (for example the way Opera marks searched keywords in a web page) and/or marked by any other conspicuous mark that preferably jumps immediately to the eyes, such as for example any emails from one or more patent agents or from one or more patent offices (which might for example contain reminders about office actions which urgently need to be replied to). (Being able to keep emails for example automatically in a separate folder according to various criteria exists in some client email programs and refers to folders on the same computer, but the above variation relates to being able to define such rules on the server and typically the different locations would refer to different target computers). Another possible variation is that for example if the user wants to download email messages for example from an Online web based email account such as for example Google&#39;s Gmail, preferably the user can for example mark any email messages which he/she wants do download, preferably with the ability to use for example shift or some similar key for example to click on 2 emails and thus automatically mark also all the emails in between them, and/or for example the user can preferably use search to choose for example all the emails that contain a certain word or words for example in their title or inside their text itself and/or for example emails from a certain sender and/or for example emails from a certain date or range of dates, and can preferably for example press a key or button which automatically marks all the emails that are in the search results (preferably without having to see all the results, so that for example even if there are a few hundreds or thousands of email messages which are in the search results, the user can preferably for example look at one or two pages of results and mark the entire set of results) or for example the user can use a selection tool which marks emails for example according to such criteria without even performing a search, and/or for example if the emails are numbered the user can preferably for example also request to automatically download for example one or more ranges of emails numbers, and then preferably for example with a single additional click the user can preferably start downloading all the marked or selected or requested emails to his/her local computer, for example as multiple files in one or more directories or for example as one or a number of cumulative files. Similarly, for example when using normal email client programs which connect to an online email server there is a problem that such client problems typically first download the email messages to the user&#39;s computer and only then let the user for example choose which email messages to look at. So preferably this is improved so that the client program can for example first download all the titles and then allows the user for example to use any of the above described or similar tools to select emails or ranges or groups of emails and then tell the client program for example to download all the selected emails. Another possible variation is that such client programs can also connect for example to online web-based email servers such as for example Gmail and can preferably similarly first download preferably automatically and list preferably all the titles (or for example all the titles since a certain date) and preferably enable similarly to apply such commands as described above for automatically selecting and downloading large groups of emails at once according to the user defined criteria. Another possible variation is that preferably for example the email client program or the browser enable the user also to similarly use such search criteria or selection rules (which preferably can be also for example to automatically delete emails which do not contain for example a certain set of words or code) also for example for efficient and quick mass deletion of unwanted email messages for example from the server and/or for example from the user&#39;s local computer. Another possible variation is that the user can also for example request to sort email items according to their size and/or request to display the size of each item preferably next to it (which can be very useful for example when the user simply wants to deletes some of the biggest space-occupying items), and/or for example the user can request for example to move all the items which are beyond a certain size or from a certain size to a special separate directory and/or for example mark them automatically in a preferably visible conspicuous way and/or for example request to delete automatically all items which are beyond a certain size or from a certain size, for example with or without automatic request for user verification for each item before its actual deletion. Another possible variation is that the user can for example request the email client program for example to search for a certain email or emails which the user sent before, for example according to subject and/or recipient and/or for example certain keywords, and for example create automatically a new identical email message for one or more other recipients, preferably for example in one command. Another possible variation is that for example when starting to enter a recipient&#39;s address in a new email message and for example the browser or other email client automatically complements the string based on exiting address—preferably the browser or other email client program preferably takes into account automatically also the user&#39;s most common and/or most recent choices that fit the already typed characters so as to increase the chance of predicting correctly the user&#39;s intentions, and/or preferably the browser or other email client preferably takes into account also additional parameters, such as for example the way the email is being sent—for example if the user is sending a link from a web page and the user typically tends to send a link to an open web page to just to 1 or 2 specific recipients, preferably this is also taken into account when generating the most likely automatic address completion in order to improve further the chance for correctly predicting the recipient address which the user intends to enter. Of course, like all other places in this application, various combinations of the above and other variations can also be used, and these features can be used also independently of any other features. 
         [0105]    Another problem recently discovered by security experts is that for example if the computer has an attached microphone and voice commands are enabled, for example in Windows Vista, a malicious voice file might be used in order to take over a user&#39;s computer, for example by entering command that will download and execute some file (One of the researchers was able to use this in a demonstration in a way that even the UAC in Vista did not stop it, even though the UAC would stop for example a direct command to delete files). So preferably in order to further reduce the chance of such hacking succeeding, preferably the OS learns and identifies automatically the distinctive voice characteristic of the user so that if the commands are suddenly entered in another voice preferably the OS ignores them unless for example authorized by the uses for example by a click of the mouse, and/or for example the OS takes into account automatically what is being played by the speakers and compares it to the input it receives on the microphone and thus automatically ignores input from the speakers, and/or for example the microphone contains more than one sensor so that preferably it is set to accept input only from in front of the compute, preferably by eliminating noise from the sides or back, which can thus neutralize interference from the speakers (which is therefore also good in general for improving the voice recognition of words spoken by the user and reducing noise and feedback from the speakers), and/or or example any voice commands than can lead to downloading or execution of files also require explicit authorization for example by clicking with the mouse. 
         [0106]    Another possible variation is that the user can for example perform commands that affect a group of open windows (preferably of the same application—for example browser windows, and/or for example tabs)—so that the user can for example enter a command that prints all of them or that saves all of them or that bookmarks all of them—for example by entering the global command in one of the open windows of the same application, or for example by marking multiple boxes in the task bar or in the tabs handles bar (for example by clicking with the mouse while the shift or control keys are pressed) and then entering the command, such as for example ̂S for saving all of the marked windows (and/or tabs), ̂D for bookmarking them, and ̂P for printing them. Another possible variation is that the user can for example automatically change together the size of all the open windows and/or tabs (or make for example other format changes that affect automatically all of them) of the same application, so that for example if the user activates the cascade command, which reduces automatically all the open windows of the same application, he/she can preferably also restore all of them automatically to full screen with one command. Another possible variation is that if the user for example wants to print an article and does not notice that there is a link for a printer friendly version, preferably the browser looks for this link automatically in the page and preferably can ask the user automatically (for example when the user tries to print the page) if he/she wants indeed to print the page as is or to use the printer friendly link, and if the user replies positively then preferably the browser automatically goes to the printer friendly link and preferably reactivates automatically the print command for that page. For this the browser preferably goes over the links in the page and preferably looks for the most common expressions that are usually used for such links, such as for example “print”, “print version”, “printer friendly” “printer friendly version”, etc., and/or for example finds it according the html content of the link, such as for example “javascript:window.print( )”. Another possible variation is that in this mode the user can for example choose automatic carrying out of the global command or for example to be prompted for each of the windows for example with the option to choose yes or no in each case. Similarly, for example when the user wants to print an original patent image file in the EPO and/or for example print the drawings of a patent in the USPTO, in the prior art he/she usually has to request and print each page separately, which can be quite cumbersome and lengthy. So preferably these databases are of course improved so that the user can for example press an icon which allows printing for example the entire images pages or for example a range of pages. Another possible variation is that even without improving the available options in the site itself, preferably the browser itself can allow the user to define a set of steps to be performed automatically, such as for example pressing the icon or link that leads to the next page and then printing it, so that for example after pressing for example once or twice the “next page” link and printing it, preferably the user can activate a command that tells the browser for example to repeat the last N actions for example an additional M times and/or for example until it is no longer possible (for example after reaching the last page the next page icon is no longer active). Another possible variation is that the user can for example preferably easily give the browser for example a list of parameters and then let it preferably automatically repeat the same action on each element of the list—for example give the browser a name of a file with application numbers and tell it to search them one after the other for example at the USPTO PAIR portal, and preferably also for example the user can tell the browser for example do print or for example add to a file specific fields in the results page. For this again the user preferably for example shows the browser an example of the desired action or sequence of actions and then for example activate a command that tells the browser to repeat the same last action or sequence of actions on the entire list of parameters. Another possible variation is for example a separate software application or for example browser plug-in that can similarly print preferably entire patents for example from the USPTO or for example from the European patent office web sites preferably automatically after being pointed to the start of the application of for example to any part of it, or for example even print multiple patents automatically (for example by being given a list of patent numbers as parameter or parameters), and this application or plug-in preferably works similarly by preferably automatically repeating the needed steps for each application, thus preferably automatically requesting the needed next page each time and automatically printing it. Or for example the browser learns automatically when the user repeats an action, such as for example incrementing or decrementing a certain number in the url repeatedly, so that for example after 2 or 3 or more such repetitions preferably the browser has learned it ands the user can for example press some button or control for next or previous number and then preferably the browser automatically increments or decrements the relevant number and brings the user to the next relevant url, and preferably the browser also performs in this case automatic smart look-ahead, so that for example the browser already brings into the cache one or more of the next predicted numbers which the user is most likely to continue to, so that when the user request to continue to the next number or decrement the number or for example enters the number manually preferably the browser can display the next page instantly. Another possible variation is that the user can for example also give the browser a range of that number as a parameter and then the browser can preferably for example open automatically a whole group of tabs, one for each of the urls that contain the number in the appropriate place in the url address, or for example automatically open one tab which contains in its history the range of numbers, so that the user can then use for example the normal forward or backwards arrows or icons to go back or forth in that tab on the range and the browser preferably continues to load the entire range into the cache at the same time, or for example the user can tell the browser for example to automatically save the entire range of urls for example in multiple local files (with each file name for example based on the url) or for example in one or more incremental files, and/or for example to automatically print the entire range. Similarly, if the user for example saves a series of urls or for example video files or images which end for example with an incrementing number and the user for example adds a certain prefix to the name, then preferably by default the browser automatically remembers the prefix and preferably offers to add the prefix the next time the user saves a file in the series, and/or for example this is applied automatically by the browser when the user marks multiple files and saves them in one save command. Another possible variation is that the user can tell the browser for example to repeat this run with the multiple parameters for example every day (or other convenient interval) and preferably save the relevant results each time and for example issue an automatic alert when anything has changed (for example by running automatic compare between the new results and the saved results) and then preferably for example the browser (or other application) indicates to the user the changes since the last run. Similarly preferably the report can also for example search the private PAIR and for example generate automatically the list of expected next examination reports, for example sorted by application number or name or sorted by time till examination. In addition, preferably the PAIR portal is improved to include preferably in the main status record preferably also the time for response (for example 3 month or 1 months) so that preferably the automatic generation of these records can preferably include automatically also the amount of time to respond and/or for example the final dates to respond for example with and/or without needing to pay for extension, so that the viewer of the report does not have to view manually each individual office action in order to have this information organized, and/or for example the client application or service can automatically also sort the results according to urgency of response and/or for example generate automatically also data that can be preferably directly read for example into a spreadsheet or into a scheduler. Preferably the actual date deadlines can be computed automatically for example by the USPTO server or by the service or by the client application, so that preferably when the USPO record is updated preferably only the time to respond (preferably in months) needs to be entered by the clerk or by the examiner, since the dates to respond can be computed automatically from this and from the mailing date of the office action. Another possible variation is that preferably when pressing for example a Javascript button which designates a link with the right mouse key, preferably the same options are available as when pressing for example the right mouse button over normal links, such as for example Open in a new Window instead of in the current window, or Save the link target instead of opening it, etc. (in the prior art buttons that designate links can only be opened normally by clicking on the left mouse button). Similarly, preferably the browser shows the action defined by the button at least when the user&#39;s mouse is near the button or above it (or even all the time), for example by showing the button with a semi-transparent color that lets the user to see text under it, so that the user can know in advance what to expect, and if for example pressing the button activates some Javascript function then preferably at least the function name is shown. Another possible variation is that when typing for example one or more words or part of a url address in the location window of the browser, preferably the browser does not attempt to go automatically to the “.com” address, but can for example check also, preferably simultaneously, if the address can be resolved also to other TLDs (Top Level Domains) or other domain extensions, such as for example “.net”, “.org”, “.info”, “.co.uk”, etc., and then preferably the browser opens for example a scroll Window of the existing addresses and lets the user choose the desired one. Another possible variation is that in such cases the browser can also for example check automatically in the background, for example on a search engine like Google, which of these possibilities shows up higher (i.e. for example has more links pointing to it) and then preferably sort the options by this popularity index (for example number of links pointing to it) or even for example choose automatically the most popular option, so that if for example aol.net has a higher score than aol.com then for example typing in the location window the word aol will automatically lead by default to aol.net instead of aol.com. In addition preferably if the browser for example does not find a domain with “www.” at its beginning it preferably tries automatically also without the “www.” and vice versa. Another possible variation is that preferably the browser is improved so that for example if a certain given URL (for example from a link which the user clicks on or for example if the user types it himself/herself in the location window) is not found, preferably the browser can automatically check in a search engine (for example Google) for similar urls and display for example a sorted list of closest most likely alternatives. However, this is preferably done differently for example if it was a link which the user clicked on than if the user typed it in directly, since for example when the user types the url directly there is much more chance for typing errors, so preferably various heuristics are used in this case for checking for typing errors, for example according to close characters on the keyboard and typical errors. (Although Netscape for example goes automatically to a search page if a domain name is not found, in the prior art if a url within a domain is not found then the browser displays an error message of the server in that domain, and also apparently netscape searches for the words as keywords instead of trying to check for example for mistyped very similar urls). Another possible variation is that web servers are improved so that if a page is not found the server itself for example offers such a preferably sorted list according to similar pages (preferably according to the path and file name) in the same directory and/or for example in similar directories (preferably based also for example on automatic removal of spaces if the url with the space is not found) and/or for example the browser itself tries automatically to remove spaces from the url at least if the url with the space or spaces is not found. Another possible variation is that preferably for example the Internet browser or some other application or for example some external service on the web can for example monitor automatically a list of one or more specified domains or urls preferably at short intervals (for example every few minutes or any other reasonable period) and can preferably automatically notify the user (for example by email or SMS or visual and/or auditory message on the screen) if and when the server is down or the domain or url is unreachable for any other reason. In addition, preferably the user can tell for example the OS and/or the browser and/or for example the service that the user acquired domain names from, to automatically perform all the actions necessary to renew one or more specific domains on time even if the user forgets to do it (for example the browser can automatically login to the site and perform the necessary actions for renewal, or for example the service is instructed to renew it automatically like a subscription if the user does not cancel the automatic renewal until the automatic renewal time, etc.). (This is very important since even huge companies sometimes forget to renew on time important domain names eventhough they get automatic reminders from the domain name service). Another possible variation is that for example the OS and/or the browser can automatically sense the width or size of the screen and/or the resolution and/or number of fonts available, so that for example if a table does not fit in the page and necessitates creating automatically for example a horizontal scroll bar, preferably the browser and/or the OS can for example decide automatically to reduce the font size accordingly so that the scroll bar is not needed (this is preferably done for example only if the automatic reduction is of a limited size, for example up to 20% or any other reasonable ratio, preferably so that the font does not become too small to read). Another possible variation is that the browser can similarly also decide automatically for example to reduce only the width of the fonts, so that the fonts become thinner, which can be easier and more convenient to read than a font that is also smaller in height. This can save a lot of time and increase surfing efficiency. Another possible variation is that for example both a color printer (for example inkjet) and a non-color printer (for example laser) can be connected together to the same computer and for example when printing pages the system can for example automatically decide to send for example print jobs and/or even for example parts of them—for example individual pages to either of the two printers, for example according to the amount of color in them, so that for example pages with color beyond a certain threshold can automatically be routed to the color printer. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0107]    Another preferable improvement is that preferably the user is warned automatically for example by the browser and/or by the email client if an http link (for example in a web site or in an email message) is trying to deceive him/her. For example there are email messages that pretend to come from PayPal or Ebay or various banks and tell the user that someone unauthorized has accessed his/her data and invite him/her to click on a link in order to check or update his/her data, and the visible link says for example https://www.paypal.com but the real link within the href is somewhere else, so that the user is lured onto a phony site and into revealing secret information, such as for example his/her credit card number, account number, passwords, etc. (This kind of fraud attempts has increased dramatically in the last year and is commonly called phishing, and a large number of users are indeed fooled by it into revealing their data). So in such cases preferably for example the browser or the email client (and/or other application) automatically indicates to the user preferably in a conspicuous manner (for example by flashing the real link within the href and/or displaying a warning for example that the entire page or email is suspect, for example with a recommendation not to click on the link) that the real href is different and thus the link is phony, and/or for example warns the user about this when he/she clicks on the link and gives him/her a chance to cancel before actually going to the linked site and/or for example blocks altogether access to that link and/or for example goes instead to the visible link which the user thought he/she was going to instead of the phony link inside the href. For example preferably immediately when displaying the email or web page or before displaying it the system can flash a conspicuous warning that the entire html page or email message that contains the phony link is therefore most likely a phishing attempt and therefore should be ignored (this flashing of the warning can be done for example together with displaying the page or email message or even before displaying it, so that for example unless the user explicitly requests to view it anyway it is not displayed at all). Of course, like in other places, various combinations can also be used, such as for example both warning the user about the misfit phony link and about the fakeness of the page or email message altogether, and then if the user still allows going to the link, going only to the visible link instead of the phony link, since for example the user might press by mistake or without noticing the wrong answer. (In this case if the user for example still wants to go to the phony address (for example for research or law enforcement purposes) preferably for example he/she has to manually cut and paste the phony url). Of course, in such clear cases of misleading hrefs (for example Email messages that contain clearly misleading hrefs where the visible link does not fit the real link) the email message can also for example be automatically blocked for example by spam filters (with or without notifying the user about this blocking) for example on the user&#39;s own computer or for example on a corporate firewall or ISP&#39;s firewall or mail server, thus not reaching the user at all (for example unless the user is also notified about it and for example requests explicitly to view it anyway). (Preferably normal spam filters are also improved to identify automatically for example typical patterns of mixing digits and/or other non-letter characters with letters in a way that tries to bypass word filters). However, the visible link might just say in this example for example “Paypal” without the full url, in which case it is more difficult to be sure of the attempt to mislead the user, or for example might simply say something like “click here to activate your account”, etc., so another possible variation is that preferably for example the browser or email client automatically indicates to the user also the real url that is within the href (preferably in the normal display of the page—for example next to the link or superimposed on it, preferably even when the mouse is not near it, and not just in a line at the bottom of the window when the mouse is standing on the link, as is done in the prior art, since many times the user clicks quickly without even noticing it, and preferably the browser (or other application) of course makes sure that this is clearly visible, thus preferably ignoring for example any font size and/or font color command which might hide it and/or for example making it automatically even more conspicuous than the normal text). This is important because eventhough the user might discover the deception after clicking on the link, this is still dangerous, because the link might for example point to a site that contains a hostile code that takes advantage of some vulnerability for example in the browser or in some plug-in and thus can compromise the user&#39;s computer and for example steal or destroy information or plant a Trojan horse on the user&#39;s computer (This is also why these smart phishing protection methods, and/or checking against known black lists, are preferably done BEFORE the user has a chance to click on the link, since identifying a phishing site after the user has already entered it is much more dangerous since it already exposes the user to possible exploitation of various vulnerabilities even if he/she discovers the deception after reading the web page itself and/or does not eventually enter personal data there). Indeed for example McAfee Site Advisor since March 2006 (after most of this paragraph was already filed in earlier priorities of this application) automatically marks dangerous links (based on reported sites which contain malware), but only on the results page of a few search engines. So preferably, as explained above, such warnings are preferably applied also to normal links in preferably any web pages, which means preferably any links on the page, including for example any advertisements for example on the search engine results or on normal web pages. The marking of dangerous or suspect links is preferably done for example automatically when the page is loaded. (In order to avoid delays in loading the page, preferably first the page is displayed by the browser and preferably only then the markings are added to links where needed, preferably dynamically for example through a plug-in or by the browser itself, and/or for example markings are added dynamically to dangerous or suspect links when the user moves the mouse near them). However, another problem is that links can for example deceive services like Site Advisor for example by using automatic redirection, so preferably the browser is improved so that for example it preferably warns the user and asks him/her in advance before allowing automatic redirection to occur, and/or for example warns the user if the site tries to open for example a window or a frame in a size which is too small to see (which can typically be some exploit attempt), and/or for example such a plug-in can perform these additional checks, for example when the user tries to click on the link, or for example during building the database of suspicious sites. Another possible variation is that for example the browser and/or for example the OS and/or for example the security system (and/or for example another software, such as for example the email client or the spam filter) can for example automatically conduct at least some keyword analysis and/or grammatical and/or semantic analysis of the message and identify for example a typical scam which requests the user to verify data and/or can preferably identify the name of the institute which is referred to (for example according to the wording of the message and/or according to the domain name of the purported sender, which is in those cases almost always a forged email sender address which pretends to be from the domain of the relevant institution, for example Paypal, Ebay or some bank) and can for example warn the user automatically (for example about the specific links and/or about the likely fakeness of the entire page or email message) if the name of the institution appears as a file name or directory name in the real url of the href or does not appear at all or appears for example in a section before a dot before the real domain name, and/or for example in such cases can for example automatically look up the url for example in one or more whois database and for example warn the user immediately if the domain or IP address is not registered as belonging to the purported organization and/or for example appears to have been registered only a short time ago (such as for example a few days or weeks or months or any other reasonable period). Of course, a generic security system such as for example described in PCT application WOO192981 and U.S. application Ser. Nos. 10/301,575 and 10/644,841 by the present inventor provides ample protection against any such threats, however it is still a wise policy to warn the user in advance about such attempts to mislead him/her. Also, there have been attempts for example to use unreadable characters in the url that appears in the location window (for example http://www.microsoft.com[special character].hackersdomain.com), so that for example Internet Explorer will display the url only up to that character, and thus the user might not discover the deception even after clicking on the link. Although Microsoft has fixed this specific bug, other ways to display a phony url in the location window might be discovered later. So, in addition, preferably the browser automatically makes sure that the url in the location window (and/or in the display of real url which is shown even before the user clicks on the link) is indeed displayed exactly like the actual url that it connects to, and if there are for example unprintable characters then preferably they are marked with some sign and do not effect the printing of the rest of the url, and if there is for example any attempt by Javasrcipt or for example Active-X or for example some other portable code (or for example by any other program on the user&#39;s computer), to put for example other data on top of the location Window (for example by fitting another small window and/or text and/or image that appears on top of the location Window), then this is preferably automatically prevented for example by the browser and/or the OS and/or the computer&#39;s Security System, for example by automatically monitoring and preventing other programs or portable code from putting any windows in front of the browser window unless the user explicitly transfers the focus to them, and/or for example by automatically intercepting windows and/or text and/or images that have a suspect size and/or shape and/or location or that otherwise have suspicious or unusual qualities. Another possible variation is that such sites that allow the user to make monetary transactions preferably have additional precautions that prevent the thieves from doing real damage even when they succeed in luring users to divulge their secret data. These additional precautions can be for example that for any transaction or for example for transactions above some minimum amount, or for example at least during login in those sites, the user gets an automatic message directed to his/her known address (for example email or Instant Message, with a special code) which preferably contains a unique one-time use generated code, and the user has to respond to it before he/she can go on with the login or the transaction, and/or for example the user has to login from certain known IP addresses or range of addresses or address parts and cannot login at all from other places (and/or the login must be from a certain geographical positions, for example a certain range of GPS coordinates, for example when geographic IP addresses are used), or for example the challenge email is sent only if the login is from another location and/or not from the allowed IP addresses, and/or for example the user&#39;s identity is verified by a biometric method and/or by a physical identification hardware that only the user has, and/or these same methods are used for verifying attempts to use the credit card, etc. Of course, the system preferably prevents forgery of IP addresses, for example by any of the methods described for example in my Canadian application Ser. No. 10/756,839 of Jan. 11, 2004 and U.S. provisional application 60/561,160 of Apr. 9, 2004. This way even stealing for example the users&#39; account numbers and/or passwords and/or credit card numbers, still severely limits the thieves&#39; ability to use them. Similarly, preferably irregular credit card payments (preferably even for example when a physical card is presented, for example outside the Internet) and/or for example drawing money from ATM machines, are preferably instantly reported to the owner (for example by SMS to his/her cellular phone and/or normal phone and/or internet phone and/or other type of automatic voice message or instant message and/or email) and/or back-confirmation is required, for example depending on the extent of the irregularity. For example since September 2003 some banks have started experimenting with sending automatically an SMS to clients whenever a payment is made with their credit card. However, that is a bit problematic since this way eventually one way or the other the credit card companies will transfer the cost to the clients for sending an SMS for each payment, and also this might become an annoying routine and thus users would pay less attention to such messages or decide it is too much of a hassle and thus request to cancel this service. Therefore, it is much more preferable to send such an instant message automatically only when there is an irregularity. Although the idea of sending an SMS if the transaction is of a high amount has been around since December 2003, this is too extreme on the other end, since a thief might for example make multiple transactions, all with a value smaller then the threshold. Therefore, preferably the automatic messages are generated for any type of irregularity, such as for example if the transaction is made in another city or country in which the user does not usually make transactions and/or for example in a shop in which the user has not yet made transactions (or has rarely made them) and/or for example the transaction involves an item which the user has not bought before, etc. (If the type of items bought is also taken into account then this means that preferably this information is preferably transmitted automatically for example from automatic cash registers to the credit card company&#39;s computer for example at the same time that the credit cards company&#39;s computer is contacted, so this is preferably done by transmitting for example the bar codes of the items, but this might be problematic since it requires changes in many places and also some users might be concerned about the reduced privacy if this is done). When money is taken from automatic teller machines, preferably the instant message is sent every time an unusual amount is extracted (this does not have to be an unusually large amount but can preferably be for example an amount the user has never or rarely extracted before—for example $35 if the user almost always extracts for example $20 or $50) or for example every time the money is drawn from a machine which the user has never used before (or for example rarely used)(since a normal user usually pulls money from a small set of machines and, a thief who for example duplicated or stole the card would most likely use a different machine). Another possible variation is to similarly preferably highlight (for example by underline and/or boldface and/or special color and/or for example special icons or other preferably conspicuous visual indicators) such unusual credit card transactions and/or for example ATM or check withdrawals and/or for example any unusual activity, for example in bank reports and/or credit card reports which are for example sent to the customer once in a while (for example the credit card monthly report), since otherwise the user might for example not notice this, for example if the thefts are for not big amounts and only one in a while (as explained above this is preferably done automatically based on automatic analysis of the user&#39;s usage statistics). Another possible variation is that for example the bank sends the user automatically once in a while a list of all the ATM withdrawals together with an indication of the address of the ATM machine where the money was drawn (this is preferably not available by request for example at the ATM machine since otherwise the thief could also request this report), and thus for example the user can identify immediately when an amount has been withdrawn at a place where he/she never withdraws money (In normal prior art reports that list only the amounts and dates many users might not remember if they indeed withdrew that amount on that day, especially for example if the report is sent for example after a month). Another possible variation is that preferably the credit card is based on a smart card or other thin computerized gadget which looks like a credit card in size and shape but creates the magnetic flux dynamically instead of a normal magnetic stripe, and preferably the credit card works only when another device which the user carries (for example some special key added to his/her keys bundle in his/her pocket) is sufficiently close (for example up to a few meters), preferably based for example on RFID communication between the two devices, and if for example the user wants to allow someone else to use the card, preferably the user can for example punch a secret code for example through a small keyboard on the card, and then preferably the card can also be used away from the user, for example for the next N minutes and/or for example for up to X transactions and/or up to Y amount (preferably settable by the user). Another problem is that in the prior art if for example if a user&#39;s credit card is lost or stolen, many times the user might need at least a few hours to check in various places where he/she might have forgotten the card, but in the meantime the card might be used by the thieves if it was indeed stolen, which is very dangerous, but on the other hand if the user blocks or cancels the card immediately upon finding out that it is missing, this is irreversible and the card cannot be restored even if the user finds it a few minutes later, and then the user typically has to wait a few days for the new card to arrive. So preferably this is improved so that the credit card companies preferably also offer an option to block a credit card only temporarily, which means that preferably this blocking is limited in time (such as for example up to 24 hours or a few days or other reasonable period) and if at the end of the deadline the user does not reopen the card, preferably the blocking becomes automatically permanent by default and a new card is preferably automatically ordered, and preferably reopening a blocked card requires thorough identity verification in order to prevent for example the thieves from reopening a stolen blocked card (such as for example various challenge questions and/or for example phoning back from the credit card company to the user&#39;s correct phone to make sure that indeed the real owner has issued to request to reopen a blocked credit card, and/or for example required verification by email with a security code which is sent to the user&#39;s email, so that only after the user has received the request for verification with the code he can confirm it for example by clicking on a url with the security code). Another problem is that if for example a credit card is lost or stolen typically it takes the user and even the credit card company about two days to be able to see if there were any charges after the user last used the card and until the card was blocked—because some businesses report deals with the credit card only after two days. So preferably this is improved so that preferably any credit card charges for example beyond a minimum threshold amount or for example any charges at all require preferably automatically that the teller query the credit card company for authorization and/or at least report automatically preferably instantly to the credit card company (which is preferably done by constant broadband connection between the teller and the credit card company&#39;s database), and/or for example whenever the teller is connected to the credit card company for any reason, preferably the credit card company automatically also sends the teller a list of all the blocked credit cards or for example all the recently blocked cards (for example if the teller keeps automatically previous reports on blocked cards in its own local database, so that preferably the teller automatically and immediately blocks any attempted deal with a blocked credit card even if it is a very small amount, such as for example just a few dollars. Of course various combinations of the above and other variations can also be used. 
         [0108]    Another possible variation is that when the browser enters a site (i.e. this is preferably done when the user presses the link, preferably before actually transferring any content to the user, however it can be done for example also while displaying the data to the user, however that is more dangerous, or it can be done for example while displaying the data but for example no active-x or scripting for that site is allowed until the user explicitly permits it, at least for example if the browser and/or for example the OS and/or for example the security system decides that the site is suspicious) and/or for example even before the user presses the link, for example when the mouse is near it, the browser preferably automatically checks also one or more relevant WHOIS databases and displays to the user automatically also the for example name under which that domain is registered and/or for example the country and/or other details that can easily indicate to the user if a site is phony, such as for example the length of time this domain has existed. Another possible variation is that if the system (for example the browser and/or the OS and/or the security system and/or other software) for example also checks in one or more databases for known phishing sites, preferably it also identifies suspect servers which were known to host such sites before, and/or for example also checks for example in whois records if the domain seems to be related in one or more ways to previously known phishing domains, such as for example being registered to the same people, having the same email of the technical contact or billing contact, etc. In addition, preferably there is also one or more database on the Internet which collects typical word combinations and/or other typical patterns of phishing email messages, for example from messages which have been identified by humans and/or by any of the above methods, which the browser and/or other application can preferably consult automatically for example for getting the typical patterns and/or for example the browser and/or other internet application accumulates the typical wording patterns itself automatically for example when it identifies a phishing email by any of the above methods), and thus preferably the browser or other application can for example warn the user automatically of any email that seems like a typical phishing attempt even for example by typical word combinations. Another possible variation is for example keeping a list of at least the most common organization names used in typical phishing attempts (such as for example Paypal, Ebay, Citybank, etc.), so that for example the browser (or other application) gathers this lists for example by itself (for example when it identifies a phishing email by any of the above methods) and/or gets it for example from one or more online database, and then for example warning the user automatically about urls which contain the name of the organization in suspicious places, as explained above. Another possible variation is that for example the browser (or for example other internet application) also warns the user if for example the whois record has various missing data and/or for example has suspicious fields, such as for example a phone number with a number 999-9999-9999 or some other suspicious patterns, since this can also be a clear sign of a bogus or falsified data of the domain owner). Another possible variation is that for example when a browser (or other Internet application) that was patched for some exploit (or for example a firewall that was updated to catch the exploit) for example see that a website attempted to use that exploit, preferably they immediately email the site&#39;s url preferably automatically, preferably with an appropriate automatically generated message, to the appropriate database or databases to be blacklisted, so that even systems that are still unpatched will at least be able to automatically avoid the url by checking for example in the database of suspect or blacklisted urls, and/or for example special spiders are used for finding such urns or for example this is added as an extra feature to spiders that already constantly spider the web anyway, such as for example the Google spiders. Another problem is that is Vista Microsoft added to Internet Explorer protection against misuse of domain names with international characters in phishing scams, but this protection is based on. Of course various combinations of the above and other variations can also be used. 
         [0109]    Another even much more dangerous kind of attack, typically coined “DNS poisoning” or “pharming”, is based on changing data in DNS servers and/or pointing the user to a fake DNS server (which can happen for example if the user has not changed the default password of his/her local home or office router and for example visits a malicious web site which runs a Javascript program which users cross-site scripting to access the user&#39;s router and give it a fake new address for the DNS server, which is a very dangerous and widespread problem, since according to Symantec research more than half of the users don&#39;t change the default password on their local router), so that various domain names point to malicious IP addresses instead of the real IP addresses. This is even much more dangerous, since no action is required on the part of the user, and all the users that reach the infected DNS are automatically affected by the phony IP address. In order to solve this, preferably at least one of the following is done: 1. Internet Browsers and/or other internet applications which need to access domains preferably automatically query multiple DNS servers, preferably in different locations (for example at least 3 or more), and if there is a mismatch between the IP address reported by them for the same domain then preferably the browser (or other application) preferably checks in preferably many additional DNS servers and preferably chooses the one that appears in most places, and preferably also warns immediately the user (preferably before going to the site) that there might still be a risk due to the mismatch (preferably with statistics on the percent of DNS servers pointing to each IP address), and/or the browser (or other Internet application) preferably checks in one or more domain name registrars to see for example if the IP address given to the domain is compatible with the DNS servers that are associated with the domain&#39;s records, etc. Preferably the warning about the phony IP address or addresses is preferably immediately automatically also sent for example to one or more relevant authorities and preferably also to the valid site owners (for example according to the correct IP address and/or according to the emails of the contacts in the registry records). Another possible variation, preferably in addition, is that preferably the browser (or other Internet application) preferably keeps historical data of IP addresses of domains that the user has accessed and/or or of the DNS servers and preferably whenever there is suddenly a change preferably performs, preferably immediately and automatically (preferably before letting the user access the site), various checks, such as for example any of the checks described above, for example in multiple DNS servers and/or registrars and/or warns the user about it, preferably before letting the user access the site, and preferably the browser and/or the OS and/or the security system and/or other applications and/or the user&#39;s local router preferably warn the user and request authorization in advance before allowing to change the address of the DNS server or servers. Another possible variation is that preferably the home or office routers which are sold to users are preferably changed so that they do not come with a default password but preferably have for example a pre-set automatic password which is preferably different for each router and is preferably printed on a paper which the user receives with the router, and/or preferably for example when first connecting to the router or after a short time preferably for example the router or the browser or the OS or the security system preferably automatically forces the user to change the password preferably before allowing him/her to connect to the Internet or for example generates a random password preferably based on a physical process which cannot be predicted (such as for example random electrical fluctuations in the power supply and/or for example in the temperature at the time the password is generated and/or any for example other parameters of the physical environment and/or of the user&#39;s individual computer), and preferably forces the user to write it down before allowing him/her to continue, and preferably the user can also change the random password to something more memorable to him/her but preferably for example the router or the browser or the security system or the OS preferably analyze automatically the strength of the password (for example according to its length and/or type of characters used and/or heuristics and/or list of too common passwords which should be avoided) and preferably warn the user about password that are not good enough or for example refuse to accept such passwords and force the user to enter an acceptable password, and/or this analysis is preferably also performed on automatically generated passwords so that if the password is not good enough preferably another password is preferably automatically generated instead. In addition, preferably the router comes with a physical reset switch so that if the user has lost the password he/she can preferably physically press some button on the router in order to reset it, and then preferably the reset password is again not a default password but preferably the unique password that came originally with the router, and/or returning to the reset password forces again the user to change the password for example when first connecting to the router the next time, as explained above (preferably the router can indicate to the browser or OS or other application which password was preset in it, or for example the OS or browser or security system automatically demands a new password unless such a password was already automatically created by it randomly or was already manually entered by the user). Another possible variation is that preferably there are one or more preferably highly secure authorities on the Internet which verify the IP addresses of allowed DNS servers, and preferably the browser and/or other internet application and/or for example the Security system or the OS preferably automatically verify with this authority or authorities for example whenever the address of the DNS server changes or is entered for the first time if that is a valid authorized DNS server. Another possible variation, preferably in addition, is that preferably the DNS servers themselves preferably perform automatically similar checks to those described above, such as for example keeping historical data and checking with multiple sources immediately when there is a change, and/or checking with multiple sources whenever new data arrives, and/or for example verifying with the authority or authorities that other DNS servers they communicate with are indeed authorized DNS servers, etc. Another possible variation is using for example long encryption keys (for example PKI) preferably for any communication between DNS servers. Another possible variation is that preferably the DNS automatically identifies for example “birthday attacks” (statistical bombardment with guessed session Ids in order to find the correct session Id) or other statistical based attacks (preferably by keeping track of multiple communication attempts with false session Ids purportedly coming from the same server) and then preferably automatically ignores any packets from the spoofed other DNS and preferably automatically switches for example to other DNSs at least for a certain time. Another possible variation is that the browser (or other Internet application) and/or DNS server automatically checks back any IP address (for example whenever giving it in a reply or for example when it changes) also in preferably multiple reversed databases which find the domain name from an IP address. Another possible variation is that preferably the browser (or other Internet application) and/or NDS servers also check for example how long the IP address has been associated with the domain for example according to registrar records and for example if it has been associated for a short time below a certain threshold preferably performs various checks (such as for example any of the checks described above) and/or warns the user. Another possible variation is that (preferably together with keeping historical data) for example when an IP address changes, the browser (or other Internet application) and/or DNS server checks in one or more reversed Databases (which give the domain name from the IP address) if the original IP address now indeed point to a different domain, and if it is still pointing to the original domain then preferably this is immediately perceived as indication of possible DNS poisoning and preferably appropriate action is immediately taken, as described above. A similar problem is that various attack vectors can be used for disrupting the DNS pinning of browsers and/or of proxies, thus enabling for example displaying under a certain domain name a page which does not belong to the visible domain name or allowing an outside hacker to access through the user&#39;s own browser for example pages which are accessible only in the user&#39;s local Intranet. This can similarly be solved by any of the above described methods or similar method, and/or for example by the browser and/or the proxy saving a history of changes of the binding between domain names and IP addresses, and for example blocking automatically and/or issuing a warning for example when a domain which had an IP outside the user&#39;s local Intranet suddenly gets an IP inside the Intranet or vice versa (for example by keeping a DB of all the IP addresses within the local intranet). In addition preferably for example plug-ins and/or mobile code within the browser are preferably better segregated so that they cannot transfer among themselves data which comes from different domains names and/or IP addresses without the user&#39;s permission. Of course various combinations of the above and other variations can also be used. 
         [0110]    Another preferable variation is that when the OS and/or various applications support 3D objects, preferably the objects can be resized or moved in various directions in a way similar to the current processing of 2d objects, so that for example by clicking on the appropriate corner the object can be easily resized in that direction, and in this case preferably size parameters are automatically updated and preferably displayed, for example in CAD (Computer Aided Design) programs. Preferably a large taxonomy of object prototypes is available to choose from, such as for example planets, plants, trees, flowers, animals, people, vehicles, etc., and preferably these objects or prototype objects can be dragged into position and then preferably can be for example changed on the spot for example by fast scrolling over a preferably large number of objects of that prototype or sub-prototype, etc., so that preferably the object changes immediately in view, preferably while the mouse drags for example a scroll bar next to it. Another possible variation is that this scrolling can be done for example also for modular elements of the objects, such as for example leaves, branches, flowers in the plants category, car elements in the vehicles category, etc. Another possible variation is that various elements can be for example reshaped dynamically, for example in a way similar to the Goo program, except that preferably when pulling for example on a part (for example a nose in a face), preferably only that part is reshaped without affecting the parts next to it. Another problem is that for example in services such as the Google 3D Earth, which allows uses to access over the internet interactive maps which typically combine satellite images with street maps (either with the browser or with a special client program which the user downloads), when the resolution is close enough to see buildings, although the user may rotate the images in any 3D direction, since the photographs are really only 2D, many distortions can occur, so that for example the direction of viewing can be not compatible with the shown side of the buildings and/or the whole scene can become flat. Preferably this is solved by at least one of the following: a. Improving the program so that the 2D images are preferably processed in advance to create extrapolated 3D representations according to relevant visual cues, and/or for example by making the photographs in advance with two or more lenses or 2 or more cameras. b. Adding, for example at least in popular public places, multiple photographs from multiple angles, preferably from helicopters and/or balloons, which are preferably automatically combined into the processed 3D representations and/or at least become automatically integrated when the rotation and/or angle is appropriate. Another preferable improvement is adding, preferably at least in popular public places, one or more local streaming video cameras which broadcast preferably real time streaming data, so that preferably when the location and/or angle is appropriate the real time streaming data is automatically integrated. Another possible variation is that for example such cameras preferably can automatically detect and preferably for example broadcast an automatic warning when they sense that they have been for example covered with a lid or otherwise sabotaged (for example by a proximity sensor that can detect the distance to the light-blocking object and/or for example by detecting unexpected darkness for example compared to an internal clock which identifies the time of day). Preferably similar methods can be used for example in various security cameras to detect and preferably warn automatically when they are blocked or sabotaged. Preferably the displayed normal images contain special marks which indicate to user “hotspots” where addition 3D images are available and/or more details are available and/or live streaming data is available, and preferably the user can also ask the program to automatically take him/her to such spots for example automatically, for example each time the user enters a command to jump to the next nearest hotspot and/or for example clicks on one of the marked hotspots. Another problem is that when the user for example wanders sideways, typically it takes time for the application to fetch the more detailed images for the new area which the user moved to each time, thus creating an annoying wait for the data. So preferably this is improved so that the program automatically guesses for example from the pattern and/or direction and/or speed of the user&#39;s movement where he/she is most likely to continue next and so preferably the details for next area or areas are downloaded in advance before the user goes there, thus preferably reducing significantly the waiting experience. Preferably this is applied also for example in the cases when for example the user can move a virtual magnifying glass, used by the competing Microsoft application (‘Virtual Earth’), since there also the waiting experience needs to be reduced by the above advanced predictions of the next movements. Another problem is that when the user zooms in on an area, many times the exact point which the user was interested in can move out of the frame unless the user is careful to move it again to the center each time before continuing with the next zoom. So preferably this is improved so that for example if the user clicks on the point he/she is interested in and then continues with the zoom, preferably the spot that was clicked upon is preferably automatically moved by the application to the center so that is remains in focus, for example unless the user deliberately moves the area or for example clicks on a different spot. Similarly, preferably the system can automatically predict for example the zooming sequence of the user, so that for example if a user is apparently trying to zoom into the marked spot, preferably the system tries in advance to get each time the additional details at least one step before the user requests it. Similarly, preferably for example the pill such as by Given Imaging, which can photograph the human digestive system internally, is preferably improved so that it contains at least one more miniature video camera or other sensor also on the other side of the pill, and preferably each such camera can cover at least around 180 degrees, so that preferably both can cover almost all directions at the same time. This is much more efficient than the normal Given Imaging pill, since in the normal elongated pill the camera is only on one side, which means that at each given moment only the section randomly pointed to by the camera can be photographed. Another problem is that many times when filling various forms or questionnaires, the user might have to check or uncheck multiple checkboxes, as shown for example in  FIG. 6 . So preferably the browser is improved so that the user can for example darken with the mouse a group of checkboxes (for example by clicking the right button and dragging the mouse over the area while it is clicked) and then with one command for example mark or unmark the entire group, and/or for example dragging the mouse over a group of checkboxes with the left button pressed immediately marks each box on the way and dragging it with the other button pressed unmarks each checkbox on the way, or for example vice versa, etc., and/or for example pressing the Shift key (or some other key) and marking or unmarking 2 checkboxes preferably also marks or unmarks for example all the checkboxes in between. Another possible variation is that the user can for example also unmark a radio button (for example by clicking on it again or for example using another mouse key) since in the prior art once a radio button is marked it can not be unmarked except by marking another radio button which belongs to the same set. Another possible variation is that for example when a computer becomes compromised by a Trojan and becomes for example a spam-relay station, preferably there are special sites or for example routers which identify the attacking computers and can preferably send the users who&#39;s compromised computers have participated in the attack (for example by identifying identical or sufficiently similar multiple messages from these multiple origins) for example automatic warning messages, for example directly to their IP address or to their email (However, using the email is much more preferable since on many such computers there is no normal way of sending messages to this IP address which the user will see). Preferably this can be accomplished automatically, even if the Trojan for example uses forged email addresses and/or forged IP addresses, for example by any of the methods described in the present inventor&#39;s U.S. application Ser. No. 10/756,839 of Jan. 11, 2004 and Provisional application 60/561,160 of Apr. 9, 2004. For translating the user&#39;s real IP into his/her email, preferably the system works in cooperation with the immediate ISP of the inflicted computer and/or for example there are on the internet databases which automatically link email addresses or other identity indictors with the current IP of the user, which are preferably automatically updated each time the user connects or disconnects from the Internet, as described for example in U.S. application Ser. Nos. 10/756,839 and 10/905,664 by the present inventor, and preferably these databases preferably automatically allow also efficient searching according to the IP, for example by creating automatically in real time also indexes according to the IP addresses. Another possible variation is to identify for example when the user&#39;s normal Internet Browser accesses web pages from the real IP address of the inflicted IP and then for example various routers on the way or relay stations or special sites can Send the warning to the user for example when the browser tries to access a normal web page. Another possible variation is that for example the IP addresses of inflicted computers are automatically updated in one or more special URLs in real time and for example the OS and/or the browser automatically checks regularly in one of these official sources and sees if the IP address fits the real current IP address of the current user&#39;s computer and then warns the user. However, in these variation, preferably IP addresses are removed automatically when there is an indication for example automatically from the ISP that a different computer or phone number is now using that IP address, for example by the nearest ISP node automatically identifying the user&#39;s phone number, for example when a normal model or ADSL modem is used and/or some other hardware fingerprint of the computer, since otherwise the wrong user will be warned. However, this is preferably needed only if the user has an insufficiently protected firewall or for example if the user inadvertently gave the Trojan horse permission to access the web. For example the generic security system such as for example described in PCT application WO1092981 and U.S. application Ser. Nos. 10/301,575 and 10/644,841 by the present inventor describes among other things firewalls that even prevent Trojan horses from bypassing the firewall (for example by installing a driver that accesses directly the communications card or its driver), while normal firewalls can become completely ineffective when this happens. That patent also covers improved firewalls that protect for example additional communication devices in addition to or apart from the network card or modem. Another possible variation is that for example even when the user supposedly allowed such a device to be accessed, preferably the user is given also a real time indication that the device is working. For example, if the user inadvertently allows a Trojan horse or spyware to activate silently the webcam, which then can for example start to photograph and/or record what happens in the room, preferably the security system and/or the OS and/or some other software and/or for example the webcam itself will for example continuously flash some light and/or otherwise indicate to the user clearly that the webcam is for example currently filming and/or recording what is happening in the room. Preferably similar warnings are preferably generated for example if some device has been connected to the USB and data is continuously being downloaded to it or for example some wireless device is continuously broadcasting data, even if the user apparently allowed it when the firewall asked him/her. Another possible variation is that for example when the user is asked to authorize Macro commands to run for example in Word, preferably he/she also has a choice of for example allowing only macros which do not access files beyond the present document, or for example the user allows the macro to run but is automatically warned and asked for authorization whenever the Macro tries to access external files (This interception and warning can be done for example by the word processor and/or by the computer&#39;s security system and/or for example by the OS). Another possible variation is that when the word processor opens a file that contains Macros and asks the user if to enable them or not preferably for example the menu that asks this includes also for example an option of viewing the Macros before deciding. 
         [0111]    In addition, preferably when searching for example for MIDI files on the Internet preferably the search engines are improved to enable for example automatically choosing the best MIDI files, for example by displaying first the most popular files. For example, in the current prior art the MIDI search engine http://www.musicrobot.com/ (which is perhaps the best MIDI search engine) Enables users to find MIDI files according to song names and shows first a list of all the song names that contain the search string, so that if for example the user searches for the song “yesterday once more” but uses as search string the words “yesterday once”, the results are displayed for example as shown in  FIG. 4  below. As can be seen, the results are ordered not by the most popular entry (i.e. the file name that appears on most sites) but by being closest to the search string. In this prior art search engine, if the user then chooses to click for example on the most popular file (entry 4), he/she then gets a second division—according to the file length of the files with the same name (in increasing order), so that for example the list of results shows that a file named yesterdayoncemore.mid (with the length of 8,430 bytes) is available from 4 URLs (for which the user is given the links), a file with the same name and length of 24,601 bytes is available from 7 URLs (for which the user is given the links), etc. However, in reality, the file that appears in most URLs is usually the best MIDI version of the desired song, so this means that the user has to manually look for the file size that is available from the largest number of links, and sometimes there are a large number of results (especially for more popular songs) so this is cumbersome. So in order to improve this, preferably in the first stage, after choosing the set of results that are sufficiently close to the search string, preferably the search engine automatically sorts the song names by the most popular in descending order (and/or for example the similarity to the search string is also taken into account, however if the original set was chosen properly this should not be necessary since at least most of the results in the set should be relevant, and the most popular names will probably include the song that the user is actually looking for). Secondly, after choosing the desired file name, preferably the 2 nd  stage is also sorted by the number of links available for each file size (instead of the sorting by the file size in the prior art engine), and so the user can preferably typically with just 2 clicks of the mouse reach immediately the desired MIDI file that has the best chance of being a good version of the desired song. Preferably similar principles are used also for example when searching for recorded songs on the internet—for example in legal shops which sell online songs (for example in mp3 format), so that for example the user can use a meta-search over a number of such stores and can preferably use the same stages described above like in the midi file search. (This is another improvement in Internet search technology as defined for example in the present inventor&#39;s Canadian patent applications 2,443,036 of Sep. 14, 2003 and 2,444,774 of Sep. 29, 2003). Such a search or meta-search engine can for example work on a server on the Internet and/or can for example be at least partially implemented on the user&#39;s computer, for example as part of the OS (so that for example at least some of the processing of the results is done on the user&#39;s computer). Of course, MIDI files are just an example and similar principles can be used also for other types of searches, such as for example in Shopping metasearch engines, so that for example if the user is looking for example for a combined Fax-Scanner-Printer, the system preferably helps him/her choose the specific manufacturer and model for example by sorting the models by descending order of popularity. Another preferable improvement for example in such shopping metasearch is that preferably the metasearch engine can show not only a current price range but also for example a table or graph of previous prices (for example during the last few months or weeks) for example for changes in the price range and/or for example for any specific shop which has the item, which later shows up in the detailed results (so that not only the current price for that item in that shop is shown but also a graph of recent price history for that item in that shop). Another possible variation is to take into account for example also some ranking factor of the sources, so that for example Online stores that are much bigger or more important can be given higher weight. Another possible variation is that for example in shopping meta-search preferably the meta-search engine automatically deduces the user&#39;s country according to his/her IP (and/or for example asks the user about the country where he/she wants the goods shipped to) and preferably by default (or at least if the user requests it) preferably the engine automatically marks near each shop alternative if it has shipments to the user&#39;s country and/or for example puts such shops in a separate group, preferably at the beginning (and/or for example can exclude shops that don&#39;t ship to the user&#39;s county if the user requests that, but that is less preferably since the user might prefer to know all the prices in comparison even in shops that don&#39;t ship directly to his/her country). Similarly, preferably the user can for example request to sort the results for example according to countries and/or cities and/or states and/or other areas and/or for example show only shops which are in certain countries and/or cities and/or areas, and/or for example the shopping metasearch engine can automatically indicate in the list of results near each shop the city and/or state and/or area and/or country in which it is located, instead of the prior art where the user has to click on the shop to find out more about it, such as its location. This can be very useful for example if the user wants to pick up the item or items himself/herself in a certain city or area. Another improvement is such meta search features is that for example when displaying automatically generated news the user can preferably define the desired time span to cover (for example only the last N hours or N days, etc.), and/or for example the user can mark certain news items or clusters or sub-clusters as no longer interesting. This is very important since otherwise for example automatically generated news items such as for example in the Sci/Tech section in the Google News, can remain almost the same for many hours or even a few days, and thus the user misses other items (of course, as explained in the above applications, preferably the user can continue to browse for additional automatically generated news clusters, preferably until the clusters become too small, but still this can save unnecessary distractions by skipping clusters which the user has already seen and is not interested to continue seeing new items about them). Another possible variation is that the user is notified automatically (for example by email or instant message or SMS, etc.) when a sufficient number of new clusters has become available and/or when a sufficient number of new items has become available in existing clusters which the user has not requested to remove, etc. Another possible variation is that for example when sorting automatically generated news clusters the number of items in each cluster is normalized by the time factor, since clusters that have existed for a longer time (for example a few days) would normally have more items than a newer cluster (which has exited for example for 1 hour), even if the new cluster is more important, etc. Another possible variation is that preferably the user can also, preferably easily, review also historically the automatically generated items that were on the automatic newspaper (for example in the Science/Tech section or any other section) for example a few hours ago, a few days ago, a few weeks ago, or more. Preferably the user can specify for example the time in hours and/or days to jump back (or for example once the jump size has been defined each next jump is automatically of the same size), or the user specifies for example a specific date and/or time which he/she wishes to view, and/or for example the user can press some link which automatically takes him/her back at each step for example automatically for a variable time period—determined for example automatically according the amount of change (for example the amount of change in clusters and/or within them). For this preferably the MetaNews service preferably automatically keeps a history of the links for example with certain time jumps (such as for example every hour, or any other reasonable time gap) and/or for example every time a sufficient number of items have changed within clusters and/or clusters have changed, etc. Another possible variation is that, for example when displaying the automatically generated newspaper or the results of a new search, the results can preferably be displayed also for example by a combined sort that combines for example relevance or importance with time, so that for example the clusters and/or sub-clusters and/or items are sorted by a score which is based on a formula that is affected both by time and by relevance and/or importance. Another possible variation is that for example when searching for certain keywords in the meta news, preferably if there are insufficient results (for example less than 20 or any other reasonable limit, which can preferably also be changed by the user) preferably the search engine automatically increases the time frame (for example from 1 month to a few months or other reasonable period, which can preferably also be changed by the user). Another possible variation is that for example in normal web searches and/or for example in searching the dictionary and/or the thesaurus for example in the word processor the user can search for example for synonyms of words with a specific pattern or length, or for the word itself when partial data exists (which can be very useful for example for solving cross-word-puzzles), so that for example the user can use for example question marks (or any other convenient designation) to designate unknown characters. So for example if the user is looking for a Greek island which is 6 letters long and starts with “ba”, he/she can for example search for ‘ba???? Greek island’, or for example if the user searches for example for a synonym of the word satisfaction with 11 letters he/she can for example type ‘synonym(satisfaction) ???????????’ or for example ‘synonym(satisfaction,11)’, and/or for example some other convenient notation. Another possible variation is that the user can for example use wild cards in domain names, for example in the location window of the browser or in the search engine&#39;s search line, so that for example the user can type in the search line ‘http://coca* annual sales’ in order to get results only from world-wide sites that belong to coca-cola, or for example ‘population growth statistics http://*.gov’ to get results only from official government sites, etc. (Although Google for example allows to limit results to a specific domain in the advanced search or by adding the word ‘site:’ in the normal search, this is limited to a complete url, whereas the above solution is better since it enables pattern matching also for example on parts of domain names). Similarly, if the user for example includes domain names in the search words even without the “http://”, such as for example ‘uspto.gov’ then preferably results that are on pages on that domain name are preferably given higher ranking and so preferably appear at the top of the results, and/or for example the user can add some control character before the domain name to indicate that he/she only wants results from that domain name (for example ‘˜uspto.gov’ or ‘̂uspto.gov’ or ‘&amp;uspto.gov’ or other special character). Similarly, another problem is that for example when the user adds a file extension as one of the search words, such as for example “.pdf” (especially if the user includes the brackets), the user typically means that he/she wants only results that are pdf files, but Google does not return only results that are a pdf file at the top, and the user needs to use the advanced search in order to request something like that. So preferably this is improved so that when the users adds for example a file extension after a dot within brackets as one of the search words the search engine preferably assumes that the users intends to request only results with this extension (for example in the web search and/or in the local desktop search), or for example the search engine asks the user for example “did you mean only results that are a pdf file” (preferably with a link for clicking on the page of such results), or for example shows results of only pdf files for example with a question such as for example “did you mean also web pages that contain the word ‘.pdf’”, preferably at the top of the results with a link to the page of such results. Another problem is that for example in the local desktop search for example in the Google Desktop Search many times the results behave differently if the user searches in the search box that responds immediately to letters which the user types compared to when the user requests local desktop search within the browser and types for example more than one word in the browser&#39;s search box and then presses “Enter”—even when the final search string is the same in both search boxes. So preferably this is improved so that after the user finishes typing the same text in the instant search box that responds to each letter the final results are the same as when the user types the same search string in the search box of the browser version of the local desktop search—preferably by applying the same rules. 
         [0112]    Another possible variation is that the user can for example use various pattern marks when looking for general information, so that the user can for example type in the search engine (On the Internet and/or for example on the local desktop search), “distance from [1] earth to [1] moon is % N % Kilometers”, which means that for example up to 1 word (or any other desired number of words) can be between the words “from” and “earth” and between the words “to” and “moon” and a number is expected before the word kilometers, etc. (Of course this is just an example and many other notations can be used for the number of allowed words in between, including for example adding multiple times some character that stands for a wildcard for each word, but that would be less efficient). Preferably similar search patterns, for example with a numeral of the words in between or for example with a NEAR operator (for example by typing ‘[near]’ or for example by ticking a box near the search string or elsewhere on the search dialogue box or for example on one of the configuration menus that automatically enables also “near” searches), and/or for example suggesting automatically also synonyms, are preferably enabled also for example in the word processor (for example by the user requesting it, and/or offered automatically—for example by the Word processor checking in advance how many results there are altogether for the normal search and for the “near” search, so that at least if the normal search gives too few results for example the “near” search is automatically offered), since the user might for example want to find some subject and only remembers that certain words should be close to each other, and then preferably the word processor moves the user to the relevant area each time and preferably automatically marks all the relevant words that were found in it and preferably also the synonyms of these words for example if synonyms were also requested or offered automatically (This is very important since many times, especially in a large file, the user might want to search a specific topic but does not remember the exact words he/she used). Another possible variation is that for example in the search results of the Internet search engine (such as for example Google) and/or for example in the word processor document search preferably the search engine or for example the word processor preferably for example automatically offers also for example results with a number in words instead of digits or vice versa, so that for example if the user searches for “2 lines” he/she will preferably be offered preferably automatically for example also results with “two lines” or vice versa (for example “3 principles” when searching for “three principles”)(for example with automatic integration of both types of results or for example with “did you mean . . . ”). Another possible variation for example in the web search or in the word processor search is that the user can specify for example that the two (or more) words have to be in the same sentence or for example in the same paragraph. Another possible variation is that for example if the user searches for two or more words next to each other and no results or few results are found (for example in the web search or in the word processor search), preferably the search engine or for example the word processor can automatically offer to the user to perform a “near” search, and/or display already how many results will be shown in that case (in this case preferably the maximum distance between words is set automatically for example according to some default or defaults which the user can preferably also change), or for example the search engine or the word processor automatically can suggest, preferably according to the actual number of results available, in one or more incremental steps for example at once or one after the other, increasing word distances, while preferably showing the number of expected results in each case (The number of expected results is preferably shown for example by performing the actual additional search automatically in advance, or for example by heuristics based for example on various statistics), and/or for example at least if there are no or too few results (and/or as a clickable option in the search even regardless of the number of results, or even this is simply the default), the search engine or word processor preferably offers also to remove for example one or more words out of the quotation marks (preferably based on finding each time the variation or variations that will give the largest number of results preferably with minimal change from the original search request and/or preferably automatically shows also the results from “NEAR” searches (or moves the user directly to them as explained above) and preferably the search results are automatically sorted at least partially according to the distance between the words (and preferably results with the same order of words as appear in the search string get higher scores than words in another order). Another possible variation is that the user can preferably for example use a search option in the word processor which can find automatically for example areas where the search word or words appear in the highest concentration (for example absolutely and/or relative to the size of the section, which can be for example a page or paragraph or sentence), and then preferably the word processor preferably brings the user for example first of all to the area with the highest concentration (and the word processor preferably also marks the area and/or its borders automatically and preferably also all the occurrences of the search words in that area), and preferably when the user repeats the search he/she is brought for example to the next best area, or for example all areas with a concentration beyond a certain threshold are considered a correct result and the user is brought to them in sequential order each time he/she repeats the search (when searching with a single document within the word processor or for example similarly within a web page or a PDF file or similar or other format, this is the most natural and convenient option, especially if it is a large document, or similarly or example when searching over emails, for example in one or more log files or for example in a directory of email, for example on the user&#39;s local computer or on the web, such as for example gmail or other services). So for example if by default the “near” search or topic search is enabled for example in the word processor or for example within the tab displaying a web page (or for example if the user chooses to enable it, or for example if it was not enabled by default but due to too few results the word processor for example offers the user to enable it from now on for a specific search or for all the searches), then for example if the user searches for the words ‘mouse wheel’ then preferably each time the user makes this search or for example presses Control-Page Down to repeat the search, preferably the word processor will jump to the next acceptable result, which preferably includes for example places where the following words appear: ‘wheel of the mouse’, ‘mouse&#39;s scroll wheel’, etc., and/or even any sentence or paragraph or part of it where the search words and/or even synonyms of them (if synonym search is also enabled) appear for example in any order but close enough to each other (for example within the same sentence or up to N word distance from each between each two relevant words or for example within N words in total for the entire group of relevant words or for example within the same paragraph or within the same group of up to N lines, and for example all the relevant search words or their synonyms have to be there or for example it is sufficient even if for example only most of them appear in a section), and preferably the user can also mark for example in a search options window which of these rules to use and/or for example change the default N&#39;s, and, as explained above, preferably each time the word jumps to the next result preferably it marks all the words considered relevant to belong in the result, like in a normal search, except that they may be apart from each other, and as explained above preferably this is available also in other applications or for other applications or documents types, such as for example pdf documents or other formats. Similarly, preferably the synonym search includes also automatically for example various syntactic transformations for example in terms of male-female, plural-single, present-future, etc., so that for example “goes” preferably returns also “going” or vice versa. Another possible variation is that for example when the user searches for a combination of words in the word processor preferably the word processor can also for example automatically regard for example “-” like a space or vice versa, at least in case no results are found, but preferably as additional suggestions even when the results are found. Preferably the search for near words is of course not limited to the order of words given by the user. Another possible variation is the for example the browser enables at least some of the above improved search features also for example within a current web page, for example in the current tab or in all of the tabs, as explained elsewhere in this application, or for example pdf readers or xps readers or other document readers also enable this. This can be for example a general search for text within the entire open tabs, or for example searching just the urls and/or the titles (preferably both the text on the title field and any visible headlines within the body of the html pages), so that for example when the user clicks on Control-Tab, preferably typing any letters in that modes lead to instant search on text for example in the urls of preferably all the open tabs and/or on their titled and visible headlines, and then preferably all the relevant tab handles of tabs that fit the search preferably become automatically marked and/or are for example shown in a reduced list of only the relevant tabs. Another possible variation is that if a user clicks for example on a link in the results of a search engine, preferably the browser automatically identifies this (for example by using a list of the main search engine url&#39;s and/or analysis of the fact that the user submits a search string and gets a pattern of results), and then preferably (for example at least as an option which the user can for example enable or disable) the browser can for example automatically mark the words that the user searched for in the web page when displaying it (for example in a way similar to the way that pages in the Google cache show it, except that the browser can preferably do it also to normal web pages), and/or this can preferably be done also for example if the user sends the link to the web page by email to someone else, so that the search words can preferably be automatically included as a parameter (for example at the end of the url, preferably after a character which is not used in web servers for denoting where parameters begin, or for example within or after a special tag within the url), so that this is preferably only interpreted by the web browser of the receiving user, and/or for example the servers are changed to automatically mark the search words when displaying the page, for example by including the search word in one or more parameters for example after the normal url. Similarly, preferably when receiving for example news alerts for example from Google, preferably the browser for example by default or at least as one of the options, preferably identifies the string in the message that lists the search words and preferably uses this automatically to mark the occurrences of these words in the alert message itself and/or when the user clicks on the link or links that were included in the news alert. Another possible variation is that when automatically marking the search words this way preferably the browser also enters them into the default search string preferably with an ‘or’ function, as explained elsewhere in this application, so that for example by pressing ̂G the user can automatically jump each time to the next marked word, or for example there is another control especially for jumping each time to the next marked word, so that the previous default search string can remain the same without being unnecessarily affected by this. Another possible variation is that for example the Desktop Search can be activated also on a specific document or can for example automatically react to currently open windows of documents which the user is currently editing and conduct for example the “near” search on them, but that is less preferable since it can work much better as an integral function of the word processor. Another problem is that for example if the user searches for example in Word 2000 or even Word 2007 for a string of text which exists in the document but contains within itself one or more sections of deleted text which is still visible due to track changes, the word processor does not find it, even though it would be found if ‘accept tracked changes’ was applied. So preferably this is improved so that the word processor finds the searched text also in these cases, and preferably this is done without damaging the ability do find also the text if the user does include in the search also the deleted part or parts which are till visible, so that preferably when searching for the search string which the user types the word processor preferably treats the deleted text both as exiting and as not existing and finds the search string if it exists in any of these cases—both if the user included and didn&#39;t include the marked deleted text in the requested searched string, i.e. the found text is preferably considered to comply with the user&#39;s search request if it matches the user&#39;s search string either when ignoring the deleted text or when not ignoring it. (Although Altavista for example allows using the NEAR qualifier, it is more preferable to allow the user to limit the exact number of in-between words allowed). (Although for example Google already allows the user to achieve a similar effect by including a range of numbers, for example 2.40, in the search line, preferably the user can also enter a general number indicator without having to waste time thinking of an appropriate range). Another possible variation is that the user can add for example a tag that causes the results to be sorted according to this number (or numbers, if more than one number pattern is specified) (so for example the search string can be: DVD “Koi Mil Gaya” $ % N %&lt;lowest&gt; cart) (or for example indicate this by any other way), so that for example all the sites that contain the desired keywords and the number are automatically sorted in the search results by this number in descending or ascending order, as determined by the user, or for example the sorting is only among sites which are sufficiently highly ranking according to other criteria (preferably this is also determined by the user, but sorting on the entire set of appropriate results is more preferable since it can give better answers). This is somewhat similar to using shopping metasearch, except that this gives the user much more flexibility in using such sorting for almost anything, so it can cover much more possibilities than normal shopping metasearch. Another possible variation is that the user can for example tell the search engine to search for words that belong to the same item instead of just appearing together on the same page, so that for example when the users types ‘&lt;group&gt; all in one color laser printer fax scanner’ (or with any other suitable code or notation) the search engine preferably returns only pages where these words appear near a single item (for example identified by being in the same paragraph or by smart heuristics that identify items or for example simply by being within the same sentence or for example group of 1-4 sentences, etc.). In a way this is similar to the use of the ‘NEAR’ code word, except that it applies to a group of words and preferably smarter heuristics are used as explained above and not just distance in words. Another possible variation is that instead of using ‘or’ and brackets the user can for example use ‘/’ to designate ‘or’ for a single word, which is much faster and more intuitive, so that the user can for example type at the end of the above query Kilometers/miles. This can work even better for example if synonyms are also automatically activated or offered (for example in the form ‘did you mean “Morning after pill”?’ if the user searched for “day after pill”, or by automatically including also the results with at least the close synonyms), as explained for example in other applications by the present inventor. Preferably the search engine can know synonyms for example at least from various thesauruses and preferably also through automatic learning, for example based on various patterns and/or statistics (such as for example similar patterns or word combinations that appear in pages that are close on the recursive clustering analysis, wherein the clustering is based for example on keyword analysis and/or at least partial semantic analysis and/or incoming and/or outgoing links analysis. For example there are 1940 pages with the words “day after pill” and 128,000 pages with the words “morning after pill” and even 1150 pages which contain both phrases, so even without the 1150 pages the search engine can preferably understand that these two phrases are used very similarly on pages which are close on the recursive clustering and therefore are probably synonym phrases, eventhough “day” and “morning” are not normally defined as synonyms) and/or semantic understanding of pages where relevant definitions or connections are used (for example at least in some of the 1150 pages where both phrases are used it is clearly indicated that these two phrases designate the same thing). (For example when searching for various devices or components in electronics even professional users many times have trouble finding the desired items because they are referred to by different names or different terms in different places, so preferably the search engine can for example automatically deduce the connection between the different names while spidering the web, for example based on various patterns or statistics or for example by semantically understanding references or definitions that directly link two or more names at some of the pages, etc.). This means that the search engine preferably also for example checks and preferably offers for example alternatives such as for example replacing the word ‘a’ with ‘the’ or vice versa for example when the user searches for exact strings for example within quotation marks (for example offering the combination), and of course the preferably automatically included results with synonyms (and/or for example the one or more links with preferably the expected number of results shown in advance for example in brackets) can also be for example different spellings of the same word (including for example corrections of typing errors) or other alternatives. In addition, preferably when including automatically or example such synonyms or different spellings or corrected spellings in the search results, preferably this is accompanied by an automatic message for example at the top of the search results page, which can say for example something like “we assume that you meant &lt;word or words&gt; . . . since otherwise you would have only &lt;N&gt; results” or for example “Did you really mean &lt;word or words&gt;, which would give you only &lt;N&gt; results, or similar explanations (preferably of course with the synonym or different spelling word or words included in the message, and preferably with the estimated or original number of results before the automatic improvement, and preferably including a link which the user can click in order to see the original results that would have been displayed without the automatic integration of results with the automatically revised keywords. This is very important, since at least sometimes the user might want to search for something very specific even if it is an uncommon spelling or even wrong spelling and/or even if there are only few or even very few results (and even though, as explained also elsewhere in this application, the user can preferably also change the relevant defaults or rules for example through a menu, this direct link preferably enables him/her to change this instantly for specific searches). Another possible variation is that preferably the user can for example mark one or more words (for example by a control character before it) in a way that indicates to the search engine that the word should occur exactly as entered without any changes or replacements. (And as explained elsewhere in this application, including the synonyms or different spellings automatically in the results or for example as clickable links can preferably be done automatically by default, which preferably the user can change, and/or for example can be decided in specific cases automatically for example according to the absolute and/or relative number of results and/or difference and/or ratio between the number of results according to the original search string and the number of results with the automatically improved search string, and/or for example according to more specific considerations which preferably the user can also change, such as for example activating automatic integration of the additional results only if at least one of the search words does not exist for example in the dictionary and/of for example if there are no results for it and/or for example only for common typing errors, and/or for example automatic integration by default for typing errors and by default asking for clicking on the link in other types of synonyms, etc.). In addition, when revised keyword are automatically integrated and/or for example when the user clicks on a “did you mean . . . ” link (for example if clicking on the links shows also the results with the original keywords), preferably in the new results there is preferably an indication preferably near each results which keywords are included in the result, and/or at least if the extract does not show all of the search words and/or revised words that exist in the result, and/or for example at the top of the results page there are preferably statistics about how many times each original and/or revised word appears and/or for example at least about how many results there are with the original search phrase (i.e. the set of search words) and/or how many with the revised phrase, preferably of course in addition to the total number of integrated results. Another possible variation is that for example the search engine preferably includes automatic dictionary lookup and/or automatic analysis of results (such as for example checking automatically the relevant text for example in the top results pages, so that for example if the same supposed error appears in similar or identical expressions in multiple pages it is probably not a typing error at least of some of these web pages but an intended word) in order to decide of a word that produces few results is indeed a typing error or does exist in this form in an intentional way, and preferably the search engine also indicates the result of this analysis for example at the top of the results page, and/or takes this into account for deciding which strategy to use in offering additional or corrected keywords, as explained above. For example when typing ‘Baetles’ for example in the Google web search it turns out that there are around 660 pages where this word indeed appears, but it is easy to see even from the first results that there was indeed some Beatles tribute band which called itself Beatles, as can be seen for example from the expression ‘Atom and the Baetles’ which appears in more than one of the top results, even though probably in at least some of these results the word appears only because of a typing error in at least one place in the page by the page&#39;s author. Another problem is that for example when searching for a word which the user is not sure about its spelling, Google just suggests a corrected spelling only once and only with one suggested variation, so that for example if the user is not sure how to spell ‘Didgeridoo’ and enters for example ‘didjaridu’ then Google says that there are only 16 results and asks ‘Did you mean: didjeradu’, so naturally the user assumes that this is indeed the correct spelling, but clicking on this link gets this time still only 80 results, with no indication that there is still a better spelling that will give much more results. If the user then realizes that this still does not make sense since there should be much more results and tries for example to type ‘didjeridu’ then Google suddenly reveals that there are 657,000 results, so of course the user will normally assume that this is indeed the correct spelling. But luckily the second link reads ‘The Didjeridu (Didgeridoo)’, so the user might be curious to find how many results would show if he/she types ‘Didgeridoo’, and then Hocus Pocus—suddenly there are 2,990,000 results and the user can finally know that most likely he/she has reached the correct spelling (but the user might be less lucky, since if that second link had not revealed the alternative spelling the user might not find it). Similarly, for example if the user types in Google for example ‘monika Lewinsky’ Google says that there are 60,500’ results and gives the user no indication that typing ‘monica lewinksy’ will bring 2,560,000 results. This should be automatically solved by automatically offering synonyms as explained above, since by the links structure and/or the context within relevant pages the search engine would automatically find for example that Didgeridoo is a synonym of Didjeridu and find that it has much more results and offer that automatically, and by preferably offering immediately preferably more than one suggestion (which can be for example different possible spellings and/or synonyms) preferably at the same time with the number of results indicated preferably near each of them in advance, the user would be able to choose immediately the best alternative. Another possible variation is that the search engine preferably also has a knowledge base about the possible or typical permutations and/or typical errors of various word parts (for example based on vowels or phonemes), and thus can preferably automatically generate the possible alternatives and then check how many results will show for each one and preferably offer immediately for example the 2 or 3 (or other convenient number) of alternative spellings which will offer the largest number of results. The example of ‘monica lewinsky’ is further compounded by the fact that Google does not show separately how many of the results are really based on “and” and how many on “or”, as explained elsewhere in this application, so displaying this information separately (as explained elsewhere in this application can at least give the user a better indication how many results there are really for the specific spelling)(however, offering correctly preferably more than one synonym as explained above is more important). Similarly, for example in variations where the search engine reports automatically in advance the number or approximate number of results if the user chooses various alternative searches (for example as described elsewhere in this application), if “or” results are also taken into account then preferably the information about how many results are expected is preferably based on reporting also the number of pure “and” results (i.e. results in which all the search words appear) together with one or more separate numbers about results that contain also “or” (but more preferably the comparison is based only on “and” results). Another possible variation is that the search engine preferably lists automatically in the statistics of the number of results at the top of the search results also for example how many occurrences of each word in the search string exist—preferably separately for each word of the search string. Another possible variation is that preferably at least if there are sufficient results with “and” of all the search words (for example a hundred or a few hundred or more) then automatically no results that contain “or” are included at all. Another possible variation is to create for example a separate search engine that for example specializes in searching within various forums—which preferably builds its index based also on internal search within the relevant forums, thus being able to find posts in those sites even when they can&#39;t be reached through normal spidering of the pages in these sites. Another possible variation is that preferably in forums where the user can edit his/her message after posting it (such as for example http://shellrevealed.com/forums./), preferably the message automatically gets some visual indication that it has been amended and/or for example the date and time of the last amendment are preferably automatically shown together with the date of first entering the message, so that users can notice that it has been updated, and/or for example it is automatically moved in position, and/or for example (if it is a reply within a grouped thread) preferably the date and time of the amendment affects the position of the thread like when an additional message is added to it. Another possible variation is that for example in various forums or newsgroups or for example news articles in which there are comments preferably the user can view individual items based on hover, so that merely hovering with the mouse over an item preferably automatically expands the item without having to click on it (which can be done for example by Javascript or similar means), and for example when the user moves the mouse over another item the previous item closes automatically or for example remains open also, or for example the user can hover with the mouse over a certain area if the user wants to close it, and/or for example the user can change the default between automatic closing to remaining open unless for example the user explicitly clicks to close it or hovers over an area that closes it. Another possible variation is that the user can for example mark one or more of the search words as necessary (for example by adding a “!” at the end of each of them or by using quotation marks around each of them, for example if they don&#39;t have to be in a particular order, or any other convention), in which case preferably the search engine does not show results in which one of these words is missing (or for example unless there is a synonym, for example if the search includes or example automatically also synonyms). 
         [0113]    Another possible variation is that for example when requesting News alerts, instead of being able to request only by specific keywords (as it is for example in prior art Google News), preferably the user can for example mark a cluster or a specific sub-cluster, so that he/she is notified automatically on any new items that belong to that cluster (as explained above), or for example the user can use semantic qualifiers or for example mark words in brackets, so that for example he/she will be notified also about items that contain synonyms of these words, etc. Another possible variation is that meta-news sites such as for example Google News are expanded so that the meta-search engine can also search for example for keywords in news broadcasts (for example by obtaining sub-titles digitally from these news sources, which is the most preferred method, or for example by automatic OCR of sub-titles or for example by automatic speech analysis). Another possible variation is for example a search engine or meta-search engine that conducts searches also for example in online TV program guides and/or radio program guides for TV or radio broadcast (for example in cable TV, satellite or broadcasts over the Internet) so that the user can for example request to receive automatic notifications when certain keywords appear in the name and/or description of current broadcasting guides or reviews or time tables, so that for example the user can enter for example the words “black hole” and can then be notified automatically for example whenever a new broadcast is scheduled which contains these words for example in the title or in the description of the show or broadcast (which can be for example a movie, a TV series episode, a documentary, etc.). Preferably the search engine works for example by using a technology similar to the Google News, so that for example the engine scans automatically periodically (for example every hour or other reasonable interval) a list of pre-collected urls of web pages of the main cable TV, satellite TV, IP TV stations and/or other relevant content providers, and notifies the user according the requested keywords (this list can be created for example automatically and/or manually and/or semi-automatically by the search engine operators). For filtering broadcasts that were already broadcast preferably the search engine links directly to pages that list only broadcast times that have not finished already and/or for example uses also some time and date filter, and/or for example the search engine enables also searching for past broadcasts, but preferably in this case as a separate category. Preferably the user can request for example to be notified about the desired keywords for example from all the scanned sources without limitations, or for example only broadcasts in a certain country or countries and/or for example only in a certain language or languages and/or for example only from a specific list of providers, so that for example the search engine can show the user a list of all the covered content providers (preferably with additional details on them) and the user can for example select all or unselect all or select or unselect groups of providers or individual providers. This search engine can be implemented for example from a web site similar to the Google News preferably with email and/or for example SMS notifications, or for example from a Tivo or similar device which can preferably connect automatically to the Internet, or for example by a local application on the user&#39;s PC which performs the search or meta-search Online. Another possible variation is that for example the search engine or for example a web site that offers services or for example an application that is for example sold as such to end users can preferably also offer users or subscribers for example automatic notifications about when a certain url changes, and preferably the url can point for example to a normal web page or to a specific search result from internal search on some web page, such as for example the pair record of US patent applications or for example other important databases (for example data from the public PAIR or even for example from the private PAIR, in which case preferably the relevant application is also able to authenticate like a web browser or for example through using also an automatically opened window or tab of the web browser). This can also include special services, such as for example allowing the user to add a list of parameters (for example allowing a large office of patent attorneys to load a large list of all the patent applications it wants automatically monitored) so that preferably the service automatically monitors all of them and for example automatically sends to subscribers for example every morning (or other desired time or interval) the most current update of the relevant urls and/or for example only specific areas within the relevant web page and/or for example the report can be set to include only changes from the previous report or from some base report (for example by automatically activating a file comparison with a previous record or records). (Apart from email, this notification can also be sent for example in addition or instead for example by instant messages and/or SMS). This can also work great for example in combination with the feature described elsewhere in this application—of improving web servers and/or browsers so that the browser (and/or for example other programs that accesses the Internet) can request from the server for example just a certain line or lines or words or words in the page, for example defined by position (such as for example lines  20 - 22 ), and/or for example defined by content (such as for example, Bring me only lines that contain a certain search string). Of course this search and notification service can be done as a service for example by any web site, even though it is more natural to be offered for example by a search engine such as for example Google, and of course such a service can also be offered for example by the USPTO itself. (Similarly for example this can be preferably used for example by the USPTO to notify automatically for example the relevant examiner whenever a user sends an update to an office action, such as for example amended claims). Preferably subscribers to such a service pay for example a monthly subscription fee (or other reasonable interval), such as for example $50 a month, or any other reasonable amount and/or for example the amount is calculated based at least partially also on the number of applications tracked. Similar services can be offered also in other countries were similar records of application and/or patents can be accessed through the Internet). Another possible application of this is for example a warning service to website owners, so that for example whenever one or more pages in the site changes the owner preferably receives immediately for example an email or Instant Message or SMS or automated phone call about it (for example through VoIP or through a normal phone service), thus warning the owner preferably as soon as the site becomes compromised (since the owner knows if he/she changed the site or not)(preferably this is based on comparing the source code of the page to the source code previous version, which is preferably saved automatically by the service, since there might be changes which don&#39;t show up in the displayed page, and preferably especially for potentially dangerous changes the server preferably automatically generates an even more explicit and conspicuous warning, such as for example if links are added to outside urls and/or for example if links are created in which the visible link is misleading compared to the real link within the href and/or for example if invisible text or windows are suddenly added and/or for example if new executable code is added, and especially for example if it involvs trying to download files to the user). This way preferably web owners can be alerted preferably instantly if and when hackers compromise their web site and try to add hostile exploits to it. Preferably the owner can mark which pages to cover and/or for example which pages to ignore, so that for example pages which do have to change all the time will not be covered, and/or for example the user can request automatic virus or other malware scan on one or more pages that do have to change, so that even on such pages he/she is warned for example when a known exploit is detected or when certain types of changes suddenly appear, such as for example new executable code, redirection to other sites, creation of new windows, especially if they are too small to see, etc. Another possible variation is that the user can preferably be automatically notified for example whenever the search results on certain keywords fit one or more criteria (for example in the Google Web search or for example in a site like video.google.com or for example youtube.com), so that for example the user can request to be notified for example whenever there are at least N results or for example at least N new results compared to his/her last search (Where N can be preferably any number specified by the user, which means for example 1 or more) for a certain search string or for example whenever there are new results for the requested string, and/or for example (in case of for example video files, i.e. for example songs in youtube) whenever for example there are new results which have been viewed at least N times (for example absolutely and/or as some formula divided by time) and/or for example which have received at least a certain score for example from viewers and/or additional or for example automatic criteria), and/or for example the user can preferably request to be notified automatically for example if a certain stock reaches a certain price or for example goes up or down more than a certain threshold (for example in percentages or in absolute numbers) and/or for example if certain changes take place in one or more stock indexes or if some other set of once or more conditions has been fulfilled. This means that in order to notify the user that the criterion or criteria have been fulfilled preferably the search engine of the site for example automatically repeats the search for example once every few seconds or minutes or hours or for example once a day (or other reasonable interval which preferably depends on the amount of urgency needed, so that for example for stock updates preferably the interval is much shorter than for example for letting the user know that a new file is available) and/or this is done for example by the site which offers the service, if the service is for example offered by another site and not by the site that contains the search engine itself. Preferably the notification is for example by email or Instant Messages or for example through SMS or by for example by the browser itself (for example if the user is active and the computer) and preferably accompanied by an auditory cue, such as for example a synthesized voice message and/or for example opening automatically the relevant web page in the browser if the user is sitting next to the computer. Similarly, the user is preferably notified automatically for example by any of the above means for example generated by the library computer for example when one or more books are about to become overdue or are overdue or are ordered by someone and can no longer be extended—especially for example in systems where books are automatically renewed until they are ordered by someone, since in such systems many users can get used to not having to extend their books and then they don&#39;t notice when one or more books become ordered. In addition, preferably the displayed scores for example in sites like youtube are preferably shown with a larger range of values instead of the 5 stars, such as for example a visual bar with a color with changing length and/or changing color that can have preferably much more than 5 or 10 values and/or displaying for example also the exact average score on a scale of for example 1-100 and/or also other statistical parameters, such as for example the a graph Gausian curve of the responses. Another possible variation is that preferably the user rating system for example in sites such as for example youtube is improved for example into at least two separate scores so that the users can for example preferably indicate independently for example how much they like a certain video for its content (for example a video clip, which means how good the song is and/or how beautiful or interesting the video) and independently how much they like the quality of this particular file (for example in terms of sound quality and/or video quality), and preferably there is also for example a separate icon to indicate for example if the video has some A/V (Audio-Video) synch problem—which happens with some flv files. As explained elsewhere in this application, another possible variation is that preferably one or more technical quality parameters are preferably automatically calculated, for example by the server, and are preferably automatically displayed as additional scores and/or incorporated into one or more total scores, such as for example video resolution, sound sampling rate, frame rate, white noise level, etc. In addition, preferably the videos in such sites have automatic noise level protection and/or automatic volume adjustment (which can be done for example automatically by the server in advance when the files are uploaded there and/or for example done by the browser and/or by the server on the fly when playing the video). For this preferably the file and/or the relevant web page preferably contains also some parameters about its noise level such as for example the average, maximum and minimum and/or additional statistical data (which are preferably measured automatically by the server when the file is uploaded), since sometimes there are very large differences in sound levels between various videos and so the user can suddenly be exposed to a large noise when a new video is played which has much louder sound level than the last video which the user heard. Another possible variation is that preferably there is on screen constantly (preferably on or near the taskbar) a volume control which can be moved instantly (for example in case of emergency), for example in the shape of some lever or element which is preferably visible all the time and can be for example dragged or otherwise moved (instead of having to wait for some volume control window to open and then moving a lever). Another possible variation is that preferably the search engine or some other service can automatically alert the user (for example through SMS, email or Instant Message) if a certain site (or one of a list of sites provided in advance by the subscriber) becomes offline (for this preferably the service checks for example once every few minutes (or other defined interval) if the relevant urls respond properly, and preferably of course this is done with local caches or proxies disabled in order to avoid getting a response from the proxy while the site is really offline. Another possible variation is that for example in the ordinary web search and/or for example in the meta-news search the user can for example use some code or mark in a menu in order to request for example only results from a certain country or countries and/or for example only results in which the page contains at least one or a few words in a specific language or languages, and then preferably the search engine accomplishes this for example by showing only search results in which the domain name ending is of the desired country or of one of the desired countries and/or for example the owners of the domain for example according to Whois records have an email with a domain ending from the desired country or countries and/or for example the DNS records point to a server which is located in the desired county or countries and/or for example the url contains at least some text in the language of the desired country. Another problem with search engines such as for example Google is that since the engine typically automatically tries first “and” relations and then also “or”, many time the user tries to further narrow the search by adding words, but instead the number of result actually increases because the search engine also adds more “or” results, which can be confusing to the user. So preferably this is improved so that if “or” results are also included, instead of giving only the number of total results preferably the search engine gives also the number of results with only “And”, preferably showing these two statistics next to each other, and/or for example gives separately the number of results with only “And” and the number of additional results with “Or”, and/or for example shows a numbers of statistics—for example the number of results with only “And”, number of results with 1 “Or”, number of results with 2 “Or”s, etc., and/or for example a clear border is preferably drawn between the area of results that have fulfilled the full set of “And” and the area of results where at least one “And” was regarded as “Or”, and/or for example preferably near each item in the results the search engine preferably displays also the number of “And” terms that were fulfilled in that link and/or the full list of search words which were found there (for example by displaying them near each result or for example by including as many lines of text from the result url as needed to show all the relevant search words that were found, instead of automatically limiting this to 2 lines, as Google currently does with web search results, which can be used also of course independently of the above variations). (The above variations can be done of course with many types of searches, such as for example Web search, News search, newsgroup search, etc.). Another possible variation is that preferably the number of lines shown for each extract in the results page can be preferably automatically expanded if the user shows interest in it, preferably based on hovering the mouse over the extract without having to click on it (for example by using Javascript to determine the position of the mouse and to execute the automatic expansion). Similarly for example in other types of web sites where sections of text can be expanded, such as for example the description of video clips in youtube or for example descriptions of security alerts and their patches for example in the Microsoft web site, preferably similarly the user can expand the sections for example by hovering with the mouse over the expandable section or for example over a link or icon that offers expansion without having to click on it. Another possible variation is that preferably when showing the extracts that contain preferably each search word in the list of results, and preferably using sufficient lines as needed so that preferably each search word is shown at least once, as explained above, the search words are preferably marked more conspicuously than with boldface (which is the way these words are displayed in the prior art for example in the Google search results)—such as for example by automatically surrounding these words with a yellow marker (as would happen for example if the user searches for one of the words with the opera browser within the tab that displays the search results) or other preferably visually conspicuous mark, which is much more conspicuous and jumps much more quickly into the user&#39;s eyes (preferably by default), and/or preferably the user can for example define the type of automatic marking and/or the color which will be used for automatically marking the search words in the extracts that are shown in the list of search results, for example by enabling the user to indicate this to the search engine so that the search engine itself does the better marking, or for example by indicating this to the web browser, which can preferably (for example by default or after the user sets this default) preferably automatically identify listings of search results and the search words in them and can preferably automatically mark them for example in yellow marker or in other more conspicuous ways when displaying the search results page. Preferably in case this is done by the browser, preferably the browser can identify that the page contains search results and the search words for example by recognizing various typical patterns of display in such pages (such as for example the typical list structure and/or typical html tags) and/or for example by recognizing the urls of at least the main search engines, such as example Google and/or other most common search engines, so that for example when displaying the page of search results preferably the browser automatically identifies that these are search results and automatically finds the search words (which are typically in bold face and typically are listed also at the top of the search results page and/or similarly identifying the search words in the extracts) and preferably automatically marks them for example in addition or instead for example also in yellow and/or in other means, preferably including for example colors or frames, which preferably make them more conspicuous than mere boldface. Another possible variation is that preferably if the user for example marked one or two or more search words with quotation marks then preferably at least the words within quotation marks are always shown in the extract. Another possible variation is that the user can for example mark important search words (for example by adding a ‘!’ to them or by other convention), so that preferably this mark tells the search engine to always show these words in the extracts or for example even to show all the appearances of the important word or words, for example until some maximum limit, and/or for example to show such words with more context around them, such as for example with more words before or after them or for example with the full sentence. Another problem is that for example Google many times shows in the extract of each result in the results page a fraction or section of a sentence with a search word (or for example 2 words for example if they were in brackets) separated by ‘ . . . ’ and followed similarly by another fraction, so many times it is hard for the user to determine if the 2 fractions appear close enough together and actually belong to the same topic or are for example from unrelated sections of the page or document, and also Google only shows at most two fractions. So preferably this is improved so that for example preferably when showing the extract, and especially for example if synonym and/or “NEAR” search is for example enabled (preferably by default), but preferably even without it, preferably the search engine tries to show in the extract preferably near each search result the section or sections of text that have the highest concentration of search words or their synonyms (preferably even if not all of the search words are included in the section), and preferably tries to show whole sentences or even the whole paragraphs (for example at least if it is not more than a certain number of characters or words or sentences long, so that preferably at least if the distance between the fractions, for example as measured by the number of words in between is not too long, preferably fragmentation to fractions is avoided) since such sections have a higher chance of hitting the topic which the user is searching for, so that such extracts have a higher chance of being sufficient for the user to determine if such results are relevant enough and/or learning enough from the extract even without going to the actual result page. In addition preferably the search engine shows also more than 2 fractions at least when needed and/or more lines, as explained also above. Another possible variation is that for example at least if the parts of the extract with different words are from different sections of the document (for example separated by one or more other sentences) or if they are in for example even closer but still not shown consecutively (i.e. in other words preferably at least in the cases where the words are displayed in different fractions in the extract), preferably the search engine indicates in the extract how close they actually are, for example by indicating the number of words in between or for example the number of sentences in between or for example other statistics, for example by a number in brackets and/or for example by other visual marks and/or color (so that for example if the words are not shown consecutively in the extract but are for example in the same paragraph or in the same sentence, then for example the search engine can for example mark the same or a similar color on 2 or more such fractions so that for example the search engine preferably represents the amount of closeness between the fractions or for example between the words for example by the amount of similarity of color, so that for example two fractions in the extract which are for example only 1-2 sentences apart in the page or for example other threshold that is considered close are preferably shown for example in the same color or for example in two close shades of the same color—for example blue or for example close shades of some other color, and/or for example if there is a third section which is a little further away it might be marked with a more different color—for example in green or for example in blue with some shade of green, and/or for example sections that are from more far places can be marked for example in even more different or for example even contrasting colors, and preferably the marking is by light colors which preferably do not reduce readability, and/or for example only the search words themselves are marked for example according to such coloring rules and not the entire fraction), and/or for example the search engine preferably displays some clustering score near the extract which preferably takes into account at least some of the above information (so that this clustering score is preferably higher the closer the searched words appear together and/or tend to be clustered together, preferably for example by taking into account for example how many other words or for example sentences are between them for example in the chosen extract or for example on average when they appear for example in the web page, and/or for example taking into account if they appear in the same sentence in the extract and/or for example tend to appear in the same sentence in general in the page), since this information can be very important for the user for determining the relevance of the result. This is better than the prior art because for example Google many times shows in the extract a fraction of a sentence with a search word (or for example 2 words for example if they were in brackets) separated by ‘ . . . ’ and followed similarly by another fraction, so many times it is hard for the user to determine of the search words even appear in the same sentence or in the same context. Anyway, this is internal clustering of search words is preferably automatically taken into account by the search engine when sorting the results, so that preferably documents where more search words appear together for example in the same sentence or for example in the same paragraph and/or or for example with less words between them are preferably given a higher score and preferably appear higher in the results preferably even if for example there are other documents where the search words appear for example more times but are less clustered together (and/or for example even if both pages have a similar number of incoming links), and preferably the closer the clustering for example in the same sentence or with a smaller number of words in between the search words—the higher the score and positioning that the search engine gives to the result. (The above variations mean of course that preferably while spidering web pages or other relevant pages and/or while building the index preferably the search engine keeps the relevant information about the order of words and/or the division into sentences in the document so that word distances can be computed, but this in no problem since in order to be able to show the extracts at all such information needs to be kept anyway). Another possible variation is that preferably if for example Hebrew extracts are shown (and/or for example other reverse direction languages), then preferably if the text appears reversed then preferably the search engine preferably reverses it back automatically (for example by identifying automatically for example from the relevant tags in the page if the for example Hebrew is visual or logical and/or for example by applying an automatic dictionary for example on some or more of the words in the page or in the extract to see if they are reversed or proper words). Of course these variations can be used not only in normal web page search but also in other types of searches such as for example news search or other searches, and/or for example similarly for example when Google sends News alerts, so that preferably for example the clustering score is preferably included for example in each item in the news alert, and/or for example news alerts which contain items which have a higher clustering score (i.e. have a higher chance of being on topic) are for example automatically marked in a more conspicuous way and/or for example the score is automatically included in the subject. Preferably when showing in the extract such sections with high concentration of the search words or their synonyms or for example when showing more than two lines of extracts, preferably the search engine also tries to show full sentences or at least a sufficient number of words preferably both before and after each search word in order to enable better understanding of the context. Another possible variation is that for example the search engine preferably gathers automatically for example from automatic logs of search strings which users use, statistics about common word combinations and/or for example uses some dictionary or lexical or grammatical database for this, so that if for example a user enters words such as for example “episode guide” for example together with additional words even without the quotation marks, preferably the search engine gives automatically higher importance to such more common word combinations when appearing directly next to each other since it is more likely that the user intended them to appear together, so that for example if the search string is for example ‘heroes tv episode guide’ then preferably web pages with the words ‘episode guide’, which preferably contain also for example the word ‘tv’ and the word ‘heroes’ (preferably also close by or in the same sentence or same paragraph), for example preferably get a higher score than pages where for example the expression ‘heroes tv’ appears but there is no direct sequence ‘episode guide’, i.e. in other words the search engine preferably tries to regard it at least partially as if the user used quotation marks around the words which are likely intended to appear together, and so preferably tries to display such results in higher places. Preferably if as many lines of extract as needed are used instead of automatically only 2, preferably there can still be also a maximum limit per result, which preferably the user can change, however normally in most searched there should be no problem since typically most of the time users do not search for more than a few words, so preferably the extract is automatically cut by the maximum limit only in rare cases. Another possible variation is that when displaying the search results preferably words that appear only in the pointers to the page (typically in the hrefs that point to its url from other web pages) are preferably indicated as such also already in the list of results (preferably for example by a special category or tag or mark or icon near the normal extract and/or for example by showing also an extract from the pointing link, and if there is more than one such link then preferably the search engine chooses for example the link from the most authoritative place and/or for example from the page with the highest page rank and/or for example the most typical text, if for example some of the links to this result use similar wording). Another problem is that for example Google ignores various characters or words even though sometimes the user specifically wants to search for them—so that for example if the user searches for example on the Google web search for example for “ring −1” (even with the quotation marks), the search engine ignores the ‘-’ since there are various situation that indeed the user wouldn&#39;t mind for example if it is a hyphen or a space, even though if the user intended to search for the number −1 this can be vary annoying. So preferably this is improved so that for example at least if it appears to be a number with minus attached to it (characterized for example by one or more digits with a minus sign attached before it and for example at least one space before the minus and after the digits, preferably the search engine assumes automatically that this is intended to be a negative number, and/or for example at least if this is within quotation marks the search engines preferably gives higher value to the minus sign, and/or for example the user can use for example a special mark or choose for example a default option which makes such characters be regarded for example as necessary to appear next to the following and/or previous word in the results, and/or for example in cases of uncertainly the search engine preferably tries automatically to put in higher places results where the special character or characters exist (for example the minus sign in this example). Another possible variation is that for example at least if synonym search is automatically activated, preferably if the user types for example “ring minus 1” the search engine preferably automatically shows also for example results with “ring −1” and/or vice versa (for example showing also results with “ring minus 1” if the user types “ring −1”). Similarly there is a problem for example in Word 2000 and even in Word 2007 that if for example the words ‘ring −1’ reach the end of the line, the word processor sometimes breaks the line between the minus and the digits, which means that apparently the word processor does not differentiate between a hyphen (which makes sense to break the line at) and a minus sign. So preferably this is improved so that the word processor preferably automatically identifies numbers and preferably assumes for example that at least a number with a minus sign attached to it and for example at least one space before it, is intended to be a number with a negative value and not a number after a hyphen, and so preferably in such cases the word processor preferably automatically adds the line break before the minus sign. Another possible variation is that the user can for example mark a specific character to be for example at the end of a line or at the beginning of the next line if it is for example within N characters before or after the end of line, or for example the user can mark a set of characters and for example click on some control to indicate that no line breaks should occur for example within the marked section. Another problem is that for example in Word or in web browsers such as for example MSIE, Opera and Firefox the user can only search for a certain string of words but not for one word or another within the same search. So preferably this is improved that preferably the user can also use “or” in searches for example in the word processor or when searching inside a web page in the browser, for example by using the word OR in capital letters in the search string or for example by using some other control, such as for example ‘/’. Another problem is that for example in Word (even in Word 2007) the user cannot search for controls such as for example ̂Z or ̂T or ̂D or ̂z or ̂t or ̂d, since the word processor ignores this on the search. So preferably this is improved so that the word processor does not ignore such sequences and preferably regards the ‘̂’ like any normal character for the search and/or replace and the user can preferably enter such combinations directly for example in the Search or Search and Replace box. Another problem is that for example if the user opens a pdf file in a browser such as for example Opera, the tab which contains the pdf file does not allow the browser to respond to controls such as for example ̂z (undo closing of a tab) or ̂t (open new tab) or ̂d (save book mark), which are some of the most important controls in the browser. So preferably this is improved so that the browser preferably checks for such keyboard strikes before transferring them to the pdf application or to other helper applications, and preferably takes over at least for example these 3 controls preferably by default and/or at least for example asks the user if to act on them or transfer them to the pdf reading application or other helper application at least for the first time, and afterwards preferably the user can also change this back for example through an options menu in the browser. Another problem is that for example when searching in a number of steps instead of in one step, for example when using “refine search results” for example in Google, the results are many times different from the results if the user makes the search in a single step, so the user at least sometimes needs to use multiple steps, but then the user is limited for example by the fact that the maximum number of results is 1000, so if the user for example starts with the 1000 results and then has to narrow it done, the final number might be much smaller, and also using multiple steps can be tedious. So preferably this is improved so that the user can define for example a set of instructions, for example like a macro (which can preferably even include for example ‘if . . . then’ statements about results), or for example an improved search language which incorporates for example more than one step for example by entering in advance for example multiple search line strings which the search engine then uses in sequence, or for example using a single search strings which incorporate within itself more than one step, for example by using a separator that manes for example that the following search words are to be used on the results of the search of the previous search words, and/or preferably when using multiple search steps the limitation of number of results is preferably applied to the final set of results instead of the number of results in the initial step. Another possible variation is that when the search engine displays results for example in the normal web search or for example in the News search or in other type of searches, preferably it can indicate preferably near each result also for example also the size of the text, so that for example in case of a result which is for example a pdf file or a word document or similar format the size is preferably indicated for example by the number of pages, and for example in cases of results which are normal html pages preferably the size is indicated for example by the number of words or for example by the number of lines or for example by the number of pages which the web page would occupy on paper if printed (for example based on the search engine automatically calculating this parameter for example through simulated virtual printing for example while spidering the web page), so that preferably the user can have a general perception of the size of the text in each link before clicking on a specific link in the search results page. Of course like other features in this invention, the above features can be used independently of any other features of this invention. Another problem is that for example when the user searches for a string of two or more words together (typically designated by using quotation marks, Google apparently disregards the full stop at the end of sentences, eventhough if the two words are each on the other side of the full stop at the end of a sentence they are almost never the combination that the user had in mind. So preferably this is improved so that when the user searches for a combination of words which have to be next to each other and in the given order, preferably cases where there is a full stop between them are preferably ignored or for example automatically ranked lower then cases where they appear together without a full stop between them. Another problem is that for example Google and MSN search ignore completely upper case, so that for example searching for “word”, “Word” or “WORD” returns the same results, which is a s waste of important information, since many times the user&#39;s choice of upper case can give important additional information about what he/she actually has in mind. So preferably this is improved so that this information is taken into account and thus pages which contain the word in the correct case preferably appear higher in the results. So for example if the user types “Word” instead of “word” then preferably sites that deal for example with MS Word preferably appear higher in the results than sites which simply have the word “word” in various places, and for example if the user types “LED”, results which deal with LED Lights appear before results that deal for example with Led Zeppelin. Another possible variation is that when the search engine for example displays advertisements in addition to search results, based on the keywords which the user used, preferably the choice of appropriate advertisements takes into account not just the keywords themselves but also semantic and/or context related information. This can be done for example by taking into account the order of the keywords which the user used on the search and looking for example for qualifiers, such as for example “all”, “not”, “most”, etc. However such words are rarely used in keyword searches so this would be useful only sometimes. A better variation is to determine the semantic meaning and/or the context based on the search results which the user clicks on (which is especially useful if the results themselves are automatically displayed in the form of recursive clustering), so that for example the advertisements are updated accordingly when the user requests the next page of results or repeats the search with similar keywords. Of course displaying the results in the form of recursive clustering has the further advantage that much more than 20 or 30 results can be displayed for each search, since the recursive clustering can be easily applied for example to the top 100-1000 results (or other reasonable number), since as explained by other application by the present inventor (for example U.S. application Ser. No. 10/939,454) the recursive sub-clustering is preferably sorted recursively by the page ranking algorithm which is used for example in the prior art Google for displaying linearly a small number of results (or similar ranking algorithm), so the user can very quickly tune in for example to the top N results in the sub-cluster that most interests him/her. Since the number of individual results in each cluster and/or sub-cluster is preferably shown next to its heading or next to the exemplary specific results (which is preferably for example the top-ranking web page of that sub-cluster) preferably at any point in the recursive structure the user can preferably either request to view at once all of the results for example at that level of the tree (which will in that case preferably be displayed for example linearly, preferably sorted by the normal ranking algorithm), or for example click or even just hover with the mouse on a sub-cluster, which preferably brings the user to the next place in the tree, preferably with the same options again. Another possible variation is that the advertisements can be dynamically updated also on the same results page which the user already has, so that for example while the user opens new windows for some of the links and explores them, the original page is already updated based on the links which the user clicked on, for example by automatically setting automatic refresh to every 30 seconds (or any other convenient time). Another possible variation is that preferably the search engine can automatically identify the user&#39;s country or area (for example based on his/her IP address) and/or the browser preferably can tell the search engine for example at least the sex and/or age of the user (preferably the user for example is requested to enter these when installing the browser and the age is then preferably automatically updated as the time passes), and this way preferably the search engine can for example offer different advertisement based on these parameters and/or for example automatic ratings of sites can include breaking down by these parameters. Another possible variation is that for example the page rank (or other search engine ranking) of each result in the search pages is preferably automatically displayed for example as a numerical absolute value or for example as a percentage, preferably for example next to the url or title. Another possible variation is that in order to save bandwidth for example the html protocol is changed so that it is possible to define for example “refresh on a need basis”, which means that the refresh command is initiated automatically by the site when there is any change in the preferably dynamic page (so that the browser can get a refresh even if it didn&#39;t ask for it), or for example the browser asks for refresh more often (for example every 20 seconds or even less), but if nothing has changed then the browser gets just for example a code that tells it to keep the current page or window as is. The first of these two variations is more preferable since it saves also the waste of bandwidth by unnecessary refresh requests by the browsers. In addition, when the refresh is sent, preferably it can be a smart refresh, which tells the browser preferably only what to change on the page instead of having to send the entire page again. Another possible variation is to implement this “refresh on need” for example by active X and/or Java and/or Javascript and/or some plug-in or other dynamic code that is updated only when there is a need for it. Another possible variation is for example to keep the page or part of it open like a streaming audio or video so that the browser always waits for new input but preferably knows how to use the new input for updating the page without having to get the whole page again and preferably doesn&#39;t have to do anything until the new input arrives. Another possible variation is to create for example a search engine or meta search engine which searches over a database or databases of for example DVD sub-titles and/or for example TV broadcasts subtitles and/or subtitles of other types of movies and/or media, so that for example the user may be able to locate any DVDs and/or broadcasts and/or movies for example according to text in the sub-titles. This could be a great complement for example to the Google Print project which allows to search over text of printed books. Another possible variation is that for example when the DVD is accessible (or for example the relevant video file is on the hard disk or other instantly available storage media) the user can preferably for example jump directly into a desired scene by searching for the relevant keywords for example in the subtitles and for example clicking the desired result. Another possible variation is that preferably the audio and/or the subtitles are preferably displayed also at higher speeds than for example ×2 or ×3 (preferably at any speed, and preferably with automatic pitch correction, like PowerDVD does for example until at the speed of ×1.5 and ×2), since for example in PowerDVD the Audio is played only up to a speed of ×2 and the subtitles are displayed only at a speed of up to ×3. Another problem is that for example if the user watches a video at increased speed (for example ×1.5 or ×2), for example Power DVD automatically reverts back to normal speed for example when it moves to the next file (if more than one file are loaded to play in sequence) or when the user jumps to another chapter. So preferably this is improved so that by default or at least as one of the options the speed of the player remains as set by the user, at least for example until the user closes the program and reopens it, unless the user of course decides to changes the speed. Another problem is that for example in video playing applications such as for example Zoomplayer the user can jump forwards or backwards a few seconds for example by pressing the ‘&gt;’ or ‘&lt;’ key respectively, but then the user cannot see at all what happened during the time that was skipped. So preferably this is improved so that when the user jumps for example forwards or backwards for example a few seconds (or other period) in such applications, preferably instead of skipping completely the period in-between, during the jump preferably the player application automatically fast-forwards or fast-rewinds by a certain factor during the jump (such as for example ×2, ×3, ×4, ×8 or other reasonable ratio, which can preferably also be changed from the default by the user), so that preferably the user can still see at least partially during the jump also at least part of the missing sequence, and preferably the sound and sub-titles are also displayed during the jump, preferably together with automatic pitch correction like in power DVD. Another possible variation is that instead of just being able to set a single speed for DVD (or other video file) playback (for example ×1, ×1.5, ×2, ×3, ×4, etc.) the user can preferably tell the DVD player or other media player for example to use a separate speed for example for normal section and a different speed for example for sections which contain talking and/or subtitles, because if the user for example wants to watch the DVD or other video file at higher-than-normal speed, usually sections without subtitles can be watched faster than sections with subtitles (for practical purposes preferably the talking sections are simply identified according to the sections with subtitles). Another possible variation is that the user can even tell the playback program for example to automatically adjust the speed (at least for example in the sections without talking or subtitles) for example according to the amount of action or change, so that for example if almost nothing happens then the playback can automatically move faster and if for example fast action begins then the playback can automatically slow down again for example up to normal speed of ×1. This can be easily done because the mpeg encoding itself automatically indicates the amount of change between each two frames. Another possible variation is that preferably, at least as one of the options which the user can choose, the media player can automatically detect in advance sections where speech is too fast or faster then usual and for example automatically slow down the playback in these sections for example even below the normal playback speed, which can be very useful for example if there are no subtitles and the viewer is not a native speaker of the spoken language. The fast-speech detection can be done for example by detecting speech sections according to heuristics of checking the shapes and patterns of the sound wave (and/or for example by looking at the sections where there are subtitles, if there are subtitles) and then detecting for example the density of the fluctuation at the section of the speech. Another possible variation is that preferably programs that play for example songs and/or video can preferably remember automatically for example the sound level and/or the speed and/or bass level and/or treble level which the user used to play back each file (and/or for example remember the Audio-Video shift which the user used—in case of video files where the user needed to correct the shift—which happens for example with some .flv files—for example Mplayer lets the user easily fix the shift by pressing ‘−’ or ‘+’ at the right keypad, but does not remember it even when restarting the playing of the same song immediately afterwards) and preferably use these as the default speed and/or volume for the next playback of the same song or video (preferably by saving automatically for each file the code for these 2 and/or additional settings). Preferably the volume settings are relative to each other between the songs, so that for example if the user lowers or increases for example the general volume control this does not change it. Another possible variation is that the music player or video player can automatically measure the level of the bass and/or treble for each file or song or movie and can preferably automatically boost them as needed and/or later remember these values accordingly for the file. For identifying the needed levels the system preferably analyses the average sound level for example on the bass range and on the treble range and/or in general, for example for the entire file or movie or song for example for the next few coming minutes (or other reasonable time window) after the current position and preferably corrects the bass and/or the treble and/or the general volume level to reach a higher level if it is for example below a certain minimal pre-defined or user-defined threshold. More preferably the look ahead is for the entire song or movie in order to get the global averages, otherwise it might distort the internal relations. Another possible variation is that since for example the relationship between the midrange and the treble is not linear, so that at lower volumes the treble sounds weaker compared to the midrange than, preferably this is automatically compensated for by the player application, so that preferably at lower volumes the treble is automatically increased to compensate for this non-linearity. Another possible variation is to similarly compensate automatically for example for the non-linearity of the basses. Preferably the user can turn on or off these automatic compensations and preferably changing the treble or bass volume directly has a general effect independently of this. Another possible variation is that for example the codecs and/or the encoding program are improved so that the encoders that create for example the MP3 files or Mpeg2 or Mpeg4 files or other formats preferably calculate these values automatically during the encoding (for example by sections and/or globally) and preferably add them as parameters to the encoded files so that the player applications can read those values directly without having to look ahead. Another possible variation is that for example when playing MIDI files the system can for example use the MIDI file in combination with a related lyrics file to synthesize singing of the words in tune with the music. This is preferably done by a combination of standard speech synthesis algorithms together with various heuristics about good singing, such as for example adding vibrations (waves) to the voice when singing high notes, especially for example long high notes. In addition, preferably this is done in combination with a dictionary or semantic trees which include information about the emotional significance of at least the most common emotional words in songs, so that preferably various emotions can be added to the sound accordingly. Another problem with DVD subtitles for example in PowerDVD is that when the user changes for example from pan &amp; scan of 1.85:1 to 2.35:1 in many DVDs the subtitles exceed the bottom of the screen, and thus the user can read only part of them and so if he/she wants to be able to read them the user might be stuck with the lower pan &amp; scan and thus might have for example to watch the whole DVD with black stripes at the bottom and top). So this is preferably improved so that the user can for example move a control which changes the position of the subtitles and/or their size and/or for example the application automatically recomputes the position of the subtitles while taking into account the new pan &amp; scan mode so that the subtitles remain in their correct poison and/or can automatically also reduce their size or for example make them thinner if they also exceed the right or left borders of the screen, and/or for example the application simply uses a separate function to put the subtitles at the same size and position on the screen each time independently regardless of the pan &amp; scan value. The above variations have also an additional advantage since computing the position and/or size of the subtitles independently of the video displays size can help improve the translation into actual fonts, whereas letting the subtitles grow together with the video display as is done in the prior art PowerDVD causes the subtitles to become granular for example with zig-zags on the diagonal lines. Another possible variation is that preferably the user can for example increase the image of the video within the window that plays it (thus removing for example the black stripe at the bottom and/or top of the video is widescreen)—even for example if it is a partial window—i.e. not open in full-screen. Another problem is that for example PowerDVD automatically deactivates the screen saver, but does not restore it even if the video is paused or the user is away, so the user has to actually close the program in order to restore the screen saver. So preferably this is improved so that if for example PowerDVD or some other Video-playing application disables the screen saver then preferably it is automatically restored (for example by the application itself or by the OS or by some guardian application) at least whenever the video is frozen or stopped, even if the application is still running. Another problem is that for example when switching between full-screen mode to normal window mode for example in Power DVD, the position of the image of the player itself on the screen remains the same, but usually the user needs it in a different position in each of these modes, since the border of the video image changes. So preferably this is improved so that the media player preferably remembers automatically separately the position chosen by the user in full screen mode and the position chosen by the user in normal window mode, and/or for example when switching from full screen mode to the normal window mode or vice versa the media player can preferably automatically move to the appropriate similar logical position in the new mode, so that preferably its position is automatically corrected to remain similar for example relative to the new bottom border of the playing video. Another possible variation is that for example the monitor and/or for example the keyboard contain also proximity sensors which can detect for example if the user is nearby or not (for example by detecting movement visually and/or for example by volume detectors like in a car and/or detecting for example body heat and/or for example intelligent automatic recognition of human figures visually), and thus preferably the screen saver can be for example reactivated even when the Video is moving if the user is away (however if such an option is included then preferably it can be also preferably easily activated by the user, since for example the user might want the video to run constantly on display for example in a shop). Another possible variation is that for example in when applications that can play video are used which don&#39;t automatically deactivated the screen saver, preferably for example the OS itself deactivates it temporarily for example at least while the video is in fact running in front view and/or the user is present according to proximity sensing, for example as described above. Another possible variation is that when the Screen saver is temporarily deactivated for example for any reason at least there is preferably some visual indication of it, for example by some icon or text at or near the taskbar, so that the user can notice it. Another possible variation is that preferably when choosing a screen saver preferably even merely hovering with the mouse over an option automatically shows a preview of the screen saver at least in the small sample window (or even for example over the rest of the screen, preferably except the menu where the user chooses screen savers). Another possible variation is that preferably the user can request for example automatic volume normalization for example during recording and/or during playback of audio and/or video files, in which case preferably the system reads ahead in advance and for example automatically reduces any sounds that exceed the threshold and/or for example preferably each media file (for example audio files and/or video files) preferably contains at least the max sound level value and/or additional statistics about the sound level (such as for example also min value, standard deviation, mean, mode, etc), preferably at the beginning of the file. Another possible variation is that preferably for example the media player or OS or other application preferably enables the user to extract sections for example from DVD files and/or mpeg 4 and/or divx or other compressed video or audio formats without having to extract and then recompress them, preferably by letting the user mark one or more sections (for example by viewing them and marking for example the start and end points or the start point and length in time) and the preferably selecting automatically each time the nearest base frames, preferably a little before the beginning of the section and a little after the end of the section, and preferably the system or application then copies the desired section or sections as is and preferably merely adds any wrapper information that might be needed for the new file (preferably if various parameters are needed from the original file or files they are preferably read from the wrapper information of that file or files). Another possible variation is that the user can instruct the program for example to locate automatically the beginning and ends of movies or songs or other sections and extract them automatically to individual files (for example by using various heuristics such as for example identifying song labels at the beginning and end of a song like for example in VH1 or MTV, identifying silence periods or drastic change in sound, identifying fade in and fade out, and/or identifying automatically for example places where the user activated or stopped the recording, if the file is for example a recording from TV, or finding automatically digital marks of programs or songs if they exist). Another possible variation is that the user can instruct for example an application that records for example from TV or Cable TV or satellite to automatically save recorded data in advance in separate files, for example according to one or more of the above criteria. On the other hand, in this case the system might for example create also splits which the user does not want (for example if the user pauses a recording during a commercial and then continues), so preferably the user can also concatenate separate sections together for example by marking them or entering their names or numbers and requesting to concatenate them into a single file, and this is preferably similarly done without decoding and encoding again—preferably by concatenating directly with the appropriate base frames. Another possible variation is that for example the control or remote control or the relevant user interface of a VCR that records for example digitally in mpeg or divx or other compressed format or for example a TV capture and compression card connected to the PC—enables the user for example to start recording with at least two separate controls—one for recording in a new file and one for recording as a continuation of the last file. In addition preferably even after starting a recording (for example if the user made a mistake or changes his/her mind later) the user can for example, preferably even while the recording is going on, for example click or press an option which requests the system to split the newly started recording from the previous file or add it to it, in which case preferably the device for example makes the split or concatenation on the fly and continues to record, or for example marks the request and makes the final division or concatenation for example the next time the user stops the recording. If there is any problem with some formats that makes it difficult to split or concatenate for example sequences that start and end with a base frame and then adding the appropriate file wrapper, then preferably these formats are improved to enable this, since there should be no problem to do this in formats that used base frames after each set of frames that are represented by changes. Another possible variation is that for example when recording song video clips for example from VH1 or MTV or similar channels the system can for example automatically use OCR to recognize the name of the song when it appears in the label at the beginning and/or end of the video clip and thus can save it automatically for example in a file of that name. Similarly, the user can preferably for example activate a command for example in the CMD window which can concatenate for example doc files or pdf files or other special format files, so that for example the user can enter for example a wild-card command, such as for example concat off*.pdf uni.pdf (or similar format or command), which means for example to take all the pdf files that have a name that fits the pattern and concatenate them one after the other into the united file (named uni.pdf in this example), and preferably the concatenation also inserts automatically for example some separator between each two files, such as for example a preferably conspicuous horizontal border, preferably together with the file name of each file. This can be much more efficient than the prior art if the user wants for example to search for something in a large group of pdf files (for example office actions), especially for example if they are graphic scanned images, since the alternative in the prior art is to open for example all of the files into multiple windows For example with Acrobat reader). Another possible variation is that for example the user can for example mark all the desired for example pdf files for example in the open file dialogue box of the for example pdf reader and then for example they can be opened automatically into multiple tabs in the pdf reader. Another possible variation is that the OS preferably provides the user with a command for example in DOS or CMD windows (which can be called for example dfree or something similar) which preferably automatically lists the amount of free space on each of the drives and preferably shows this for example in a table or in a file which is automatically displayed. Another possible variation is that for example if the user enters a cached page for example in Google and sees that the keyword combination that he/she searched for appeared only in a linking page, preferably the link to that linking page is given automatically by the search engine so that the user can jump to that page and see the relevant href. Another possible variation is that this link links directly to the relevant href, which can be done for example by jumping to the appropriate place in a cached copy of that linking page. Another possible variation is that preferably for example the href command is improved and/or for example additional commands are available so that so that when linking to any web page for example the link can contain a reference for example to a certain string and/or for example to a certain line number in the page and the when the user clicks on such a link preferably the browser can jump directly to the desired position in the page even if there is no relevant anchor in advance in the relevant web page, which can be done for example by the browser finding the correct position when fetching the page data, and/or for example the http servers are improved for example to indicate the position automatically according to the requested parameter or parameters (for example according to requested line number, search string, or other indicators), for example by dynamically adding a location mark or anchor when sending the page. Another possible variation is that the user can for example tell the browser to pretend to be some other browser not only in general but also for example for specific sites or domains, so that for example only in certain sites or domains the browser (such a for example Opera or Firefox) will for example pretend to be MSIE (or for example MSIE of q specific version) when inquired by the site. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0114]    Another possible variation is that preferably normal users or professional musicians are given automated tools for automatic generation of music that preferably has a good chance of becoming huge hits, for example as an application that comes with the OS or as a separate program or set of programs. Preferably this is done by using a preferably large database of preferably for example midi files of songs (or similar format), which preferably contains also various preferably objective data about the success of these song, such as for example the place the songs reached on various pop charts and/or for example how long it took the song to reach the top or close to it and/or how long it stayed there and/or how long it took the song to get off the charts afterwards and/or for example how often it is still played today on normal music channels such as for example popular radio stations or one or more MTV channels and/or for example in how many cultures it is popular (for example the greatest Beatles hits have very high scores both in terms of how many people like them, how long after they were created they are still heard and/or liked and/or popular, and in how many different cultures they are popular and/or considered great hits) and/or for example how popular the song is on highly popular sites that contain video clips such as for example Youtube (for example in terms of number of viewings, preferably with taking the time since it was uploaded into account) and/or its rating for example in youtube (but preferably an improved rating, as explained elsewhere in this application, which preferably does not confound liking of the music itself for example with liking of the video for example in terms of visual effects or with technical quality issues of the specific file, preferably by using a separate rating for each of these elements or for example with the sound quality of the specific uploaded file), so that preferably the database contains a large number of hits and also preferably sufficient control songs which are preferably average or below average. The application preferably takes into account preferably basic parameters, preferably mainly of the melody, which can affect people at preferably basic psychological levels, such as for example basic elements that create repeatedly tension and relaxation, and preferably creates automatic comparison analysis of the main differences between the hits and the average or lower songs (preferably beyond any idiosyncratic style differences), such as for example the tendency of the melody to have a more wave-like shape in the hit songs, the extent to which there is more a tendency to use a significantly longer note after each few short notes even in smaller units in the hit songs, the tendency to use long or very long notes at the peaks of higher pitch notes in the hit songs (which creates a tension between the tension of the high note on the one hand and the length of the note which on the other hand creates relaxation due to habituation), the use of frequent changes in tonality to create shorter cycles of tension and more immediate relaxation in the hits, etc. Preferably the application can use this either for suggesting improvements automatically when the user tries to compose a melody or for automatic generation of at least the kernel of a good song—i.e. at least a really good short melody sequence which any musician can afterwards expand to create a full melody. In addition, preferably the application takes into account research in which users are asked for example in major hits to mark or otherwise indicate the main section or sections of the melody which they most like, since many times there are hit songs where actually only a small part of the melody is extremely good but that part is sufficient in order to make people love the song even if other parts of the melody are much less outstanding. Preferably the application contains such additional data in its database or databases and/or for example asks users to mark such sections in the hits which they most like and preferably the applications shares such data from multiple users of the application in order to update for example one or more central databases on the Internet which these applications can preferably automatically access to increase their knowledge base, so that preferably the above analyses and comparisons are preferably centered mainly on the best parts of the hit songs instead of using the entire melody. Preferably this marking is done for example by letting the user view a graph of the midi file of the song preferably during playback as can be displayed for example in the Harping program (available from http://www.harpingmidi.com/download.html), and then preferably allowing the user for example to mark the relevant section with the mouse or for example to press some key or keys or lever for example on the keyboard or with the mouse during the playback of the section or sections with the user most likes in the song, preferably with an ability to mark preferably more than two levels of liking (such as for example on a scale of 1-10 or 1-100), preferably on a preferably continuous scale—for example in a way similar to the way a perception meter is used in election campaigns focus groups, and/or this can be used for example while normally playing for example a popular version of the song as performed by the singer or singers (such as for example various ABBA hits or Beatles Hits), for example with mp3 files or for example video files, such as for example are available in youtube, with this feature for example run by the browser or by the music playing software or by some other application on the user&#39;s computer or on the web server, or for example by using an actual perception meter (for example with a physically movable dial or lever) which is preferably for example connected to the user&#39;s computer for example through one of the external ports or for example through wireless on infra red, or for example is used in focus groups for example like in election campaigns but for testing reactions of groups of people while music is being played to them, and/or for example the user&#39;s responses (for example while hearing the preferably visually displayed MIDI files or for example the mp3 or video files) are preferably measured automatically by various bio sensors, such as for example heart bit sensor, respiration sensors, brainwave sensors, etc., in a way that can preferably generate automatically for example a graph of responses which can be views or run statistically for example against the harping-like graph of the MIDI File (which shows the notes as preferably rectangles or other elongated shapes so that their length in space represents their temporal length and the spacing between them represents their temporal distance). In addition, preferably the application also takes into account for example an analysis of the types of transformations that basic structures go through in hit songs, such as for example the transformations that the basic triplet of notes for example goes through in the song “Yesterday” of the Beatles or for example the transformations that the basic group of 5-6 notes goes through for example in “California dreaming” by the Mamas and Papas (i.e. preferably the application automatically identifies the basic unit, such as for example 2 or 3 or 4-5 notes, for example by their typical patterns and/or the spaces between their occurrences) and preferably by analyzing such transformations in preferably multiple hits (or preferably mainly on the best sections of them as indicated by users), preferably the application is able to generate automatically for example rules for best types of transformations and/or rules for all allowable transformations that do not detract from the likeability of the melody or increase it and/or a classification of the typical types of transformations common in the greatest hits, so that preferably the application is also able for example to generate hit melodies systematically for example by taking for example a basic triplet for example from “Yesterday” or for example the basic 5-6 notes for example from “California dreaming” and preferably automatically exploring systematically additional or other transformations which will be for example as good as the original “Yesterday” or “California dreaming” but the resulting melody or melody section will be sufficiently different so that it cannot be accused of copying the original song, and/or for example vice versa—using the same or similar transformations of for example “Yesterday” or California dreaming” but on a different set or configuration of for example basic few base notes, so that the resulting melody can easily become a huge hit but is sufficiently different from the original because the basic preferably initial set of for example 3-5 notes is sufficiently different. In addition, preferably the application also generates systematically basic units and/or transformations which can be tested individually to check user reactions to it, for example by any of the means described above or below. Another possible variation is to use similar principles for example for trying to automatically find and recommend for the user songs which have similar patterns as songs which the user indicated that he likes, preferably based on the above described types of automatic analyses and preferably based on asking the user to mark or otherwise indicate the section or sections that he/she most likes in the song, which is a considerable improvement for example over the model of Dan Gang for recommending to users similar existing songs that they are likely to like. Preferably the users mark their most liked section or sections of the song over midi files (and/or the midis are for example automatically generated from normal recording of songs) and preferably the main melody track is automatically extracted so that the user and/or the automatic analysis can concentrate on it, and preferably the application displays and plays the song or sections of it preferably while showing the notes as preferably rectangles or other elongated shapes so that their length in space represents their temporal length (which is much more intuitive and does not require knowing to read conventional musical notes), for example like the display in the Harping program. Preferably when generating automatic tunes or when using the program to automatically improve a tune which the user tries to write, preferably apart from for example making changes by playing on the keyboard or other input device, preferably the user can also make changes for example by moving notes (for example single notes, or for example one or more groups of marked notes, or for example moving a point in a curve in the graph for example up or down and/or sideways a way that preferably all the notes for example in the immediate curve are preferably moved automatically together to crate a different shape of the curve, for example like the effect of dragging part of a face in the Goo program) with the mouse up or down or sideways or for example pulling the corner or edge of the note or notes with the mouse in order to make the note longer or shorter, so that the user can also try for example to make additional modifications or to experiment with the tune by playing with the visible graph (which is preferably Harping-like, as explained above), thus changing the tune based for example on the intuitive visual grasp of it, and preferably after every change or after a set of changes the application preferably automatically plays the sound of the relevant section so that the user can instantly hear the effects of the changes and/or the application can preferably at least as one of the options automatically improve the tonality of the notes after the user has moved them, for example in a way that automatically creates better circles of tension and more immediate relaxation, for example based on the last note in each group of notes. Another possible variation is that for example in programs like Harping or similar programs the user can for example click on any note and then the application automatically indicates to which track the note belongs, for example by marking or flashing the relevant track in the mixer window. 
         [0115]    In addition, preferably dating sites are for example improved so that for example instead of paying or with preferably lower or much lower fees (compared to normal dating sites), users are preferably exposed to advertisements which are preferably tailored automatically for example to their background and/or interests, so that for example the age, education, sex, location, fields of interest and/or any other relevant information which the users fill anyway on the web site can be used for distributing automatically advertisements much more effectively to the appropriate people. For maximum effectiveness preferably these advertisements show at the place users of the dating site typically spend most of the time—the pages that display results of potential dates and/or for example pages that display data and/or photos of specific members which the user looks up. Preferably the advertisements are textual and short, in a way similar to the Google adwords, and/or for example they are accompanied by a small image which is preferably the same size of typical photos of the potential dates, so that for example the ad preferably looks visually similar to normal results. These advertisements can be for example generated by the dating site through direct deals with advertiser or for example though a deal with a big search engine such as for example Google, in a way similar to adsense, except that for example the dating site and/or the search engine are able to use for example the background data and/or interests of the users or the better relevance advertising. Another possible variation is that since the dating site preferably works together with an external Instant Messaging client or installs such a client (with the user&#39;s permission) for example as a standalone program on the user&#39;s computer or for example as a browser plug-in, so that the user is considered to be online whenever the user in surfing the Internet regardless of whether he/she has a currently open window or tab at the dating site (as explained in other applications about dating by the present inventor), preferably this can be used also for example in combination with search engines for example like Google, so that for example by joining the dating site for free or at the reduced fees the users agree that at least some information such as for example background information and/or interests are preferably conveyed automatically for example to the search engine when these users search it, so that for example the Google advertisements become automatically more oriented to the user&#39;s background and real interests, and so preferably the dating sites gets revenues for example also from the search engine for enabling it to improve the efficiency and relevance of the advertisements to the benefit of both the users and the advertisers. (Preferably this is done for example by passing automatically and preferably anonymously the relevant data to the search engine when the user is performing the actual search, preferably for example through a browser cookie). Of course, if the dating site is for example run by the search engine itself, this can be done even more easily with automatic seamless integration. In addition, this arrangement preferably enables the advertisers to pay less per advertisement since it is more directed and thus the same advertising space can be divided more efficiently between various advertisers. Another possible variation is that this or similar data is also used automatically with rating plug-ins such as for example Alexa or similar application, so that the automatic ratings of web sites are preferably automatically broken down according to for example sex, age, education, location, etc. Another problem for example with the Google adwords is that there have been many cases where a company bought words which violated a trademark of another company, thus misdirecting traffic of people who were actually looking for the other company. So preferably this is improved so that for example the Search engine creates a copy of the list of trademarks and their owners for example from the USPTO and so preferably the search engine can automatically find cases where a third party tries to buy a word which is a trademark that belongs to some other company and in these cases for example an automatic alert is sent to a moderator which then checks it and/or an automatic warning is for example sent to the trademark owner. Another possible variation is that for example trademark owners can register in a service which automatically searches for example once in a while (for example every hour or every day or other convenient interval) for example in Google for their trademarks and notifies them automatically for example if some paid (or even unpaid) misleading results are shown for their trademark. Another possible variation is that preferably the search engine can identify click fraud automatically for example by keeping automatically track of the IP addresses of the clicking computers or users, so that for example not only repeated clicks from the same IP can be identified, but also for example patterns across multiple computers, so that if for example the click fraud is conducted by compromising multiple computers and using them as zombies or robots, preferably the search engine can also identify repeated patterns, for example if the same set of computers are involved again and again in clicking on apparently different ads (of course these patters preferably take into account also the amount of time between clicks, since for example a too small time gap can easily indicate computer-generated clicking instead of a real human clicking). Another possible variation is that preferably the dating site uses for example mail boxes in order to manage for the users all the dating related messages in a convenient way, and preferably the messages are also automatically forwarded to the user&#39;s real email but preferably for example only part of the message is copied directly to the real email and in order to read the full message preferably the user has to click on a link which brings him/her to the mailbox in the dating site (which helps bring people back to the site and helps for example managing the longs and/or statistics). Another possible variation is that for example when sending a message to another user or when receiving a message from another user, preferably the copy of the outgoing message and/or the incoming message at the user&#39;s mailbox has preferably an icon or other indication next to each message which preferably automatically indicates for example if the other person has already read the message (in case of an outgoing message), and preferably a copy of the indication if the other user is currently online is indicated there also (apart from being preferably indicated also near the other person in the search results and in his/her profile, as explained in the above applications, but this way the user can also see it directly near incoming or outgoing massages that relate to the other users. Another possible variation is that the dating site preferably shows at least two types of indications about whether other users are currently online or not—one for being online in general on the Internet (which means that an IM connection can be established with that user), and one for being currently engaged in activity in the site itself, which means that the other user can now for example be reading messages in the site, etc. In addition if the site enables users also to upload for example video files and/or voice files, preferably the site indicates clearly near each user if the user has uploaded such files and/or how many and/or shows directly their icons (for example with a preview image in case of video), since for example in MySpace the user has to click on the video icon and only then a new page opens and tells him/her if there even exists a video files for that profile, which is very inefficient since most user don&#39;t upload videos about themselves so people learn to stop even checking and thus miss the cases where there is a video. In addition, when the user writes messages for example though the web browser with the site&#39;s mail box system, preferably an error correction service is automatically performed on the message, preferably by using an error checking application on the dating site. Another possible variation is that preferably in order to enable users to gets instant results on the one hand and also create a valuable database and service on the other hand, preferably the sire is based on gradually encouraging new users to add more details, so that for example at the beginning the users can search profiles even without registering at all, afterwards in order to view additional data about other user profiles and/or contact them the new users has at least to register some basic data about himself/herself, and afterwards, preferably for example according to the system automatically monitoring the user&#39; progress, preferably especially when it is clear for example that the user is getting too many results in his/her searches (for example a few hundred or thousands and starts going manually over long lists or results and/or profiles), preferably the system encourages the user to fill a longer and/or full questionnaire and preferably get reciprocal scores in the next searches, thus creating much more efficient utilization of the database. In addition if a user for example does not respond to a message sent to him/her by another user or for example to an instant message sent by another user for example after more than a certain time, preferably the system automatically encourages that user to at least mark the reason from a set of given categories and/or for example enables him/her to give the reason in open free text, so that the sender can preferably understand why he/she did not received the reply (for example: Don&#39;t like the other user&#39;s photo, too much age difference, etc.), and this way preferably people can help each other also understand how to correct various problems which stand in their way. Another possible variation is that in order to solve the problem of perceptual gaps between the way each user perceives his/her date and the self-description of the date, preferably the dating questionnaire is improved to take this into account. Preferably this is done for example by checking a preferably large sample or samples of couples who met through the dating service and/or also couples who met outside the service and who agree to fill both the dating questionnaire and a satisfaction-from-the-mate questionnaire, in order to find preferably reliable questions and/or areas in which the gap between the self-perception and other-perception is the smallest (and/or the largest) and/or questions and/or areas in which the correlation with the satisfaction is especially good even despite the gap (or especially bad). This way in the improved questionnaire and/or improved matching procedure preferably for example questions (or areas) in which the perceptual gap is smaller and/or questions (or areas) in which the correlation with satisfaction from the mate is big anyway can preferably be given preferably automatically larger weight in the matching process, and/or for example questions (or areas) in which the perceptual gap is bigger and/or the correlation with mate satisfaction is smaller can preferably be automatically given smaller weight, so that preferably the importances that the user gives are automatically modified to take this into account, and/or for example some questions are preferably removed altogether from the questionnaire, for example if the perceptual gaps about them and/or the correlation with satisfaction are especially problematic). The reliability of the questions found is preferably tested by cross-verification between different samples or between sub-divisions of the sample or samples. The perceptual gap in each question can be for example computed according to the distance between the self-description and the perceived other in that question (i.e. for example by the absolute value of deleting the representative value of the self-description from the description of the perceived other, wherein the representative value can be for example the single value in case of a single value, or the center of gravity in case of marking more than one value in the scale for that question, or vice versa, and of course this is preferably done only for questions in which there is a linear scale) or by checking the correlation between the self description and the perceived other for that question (for example Pearson correlation, again preferably only for questions in which there is a linear scale). Another possible variation is for example to automatically increase for example in general the weight of questions in the area of attitudes and/or in the area of general background, since in these two areas there is in general a smaller perceptual gap and a better correlation with satisfaction from the mate. Similarly, in order to solve the similar perceptual problem in computer-assisted vocational choice (in vocational choice the gap is between the way the user perceives a vocation and the way the vocation is characterized for example by vocational experts or by other people who work in that vocation, and the biggest perceptual gap is between the perceptions of the user and the perceptions of the experts, since they are typically not closely familiar with most of the vocations), preferably instead of using vocational experts to characterize the vocations, preferably each vocation in the database is characterized by people who work in that vocation (preferably by using a sufficient number of such people for each vocation and preferably also a sufficient number of people for each sub-type within that vocation). In addition, preferably the vocational choice questionnaire and/or the matching procedure is similarly improved also like the above described improved method for dating—preferably by using a preferably large sample of people who describe and characterize their vocation and indicate their level of satisfaction from their vocation and/or from their job, and, again, preferably locating the questions which reliably have smaller perceptual gaps (and/or larger) between the characterization by the user and the characterization by the experts and/or the characterization by the other people who work in the vocation (as determined, like in the variation for dating described above, for example according to the distance between the centers of gravity of the scale in each question, or by the correlation), and/or questions which have a high (and/or low) correlation with the satisfaction from their vocation and/or from their job even despite the gap, and similarly preferably automatically increasing or reducing the weight of the relevant questions accordingly and/or for example removing some of the questions altogether accordingly, like described above for the improved matching procedure for dating. (Like in other places in this application, the word “each”, such as for example “each question” or for example “each level” or other word combinations that contain the word “each”, of course it does not mean necessarily all the items but simply individual items in general—both in the specification and in the claims). Another problem is that for example when applications are granted in the USPTO their publication date on the granted patent record in the USPTO web site shows only the date of grant, so if the user wants to find out if the application was published before the date of grant he/she has to go also to the Pre Grant Production Database and search for it again, and on the other hand if the user finds an application in the Pre Grant database there is no indication if it was already granted and the user has to perform a separate search again on the granted database to see if it was already granted. So preferably this is improved so that preferably in the record of granted patents there is also a separate indication (preferably at the top of the page—for example near the date of granting) which shows also the date of first publication (at least when they are not identical, but preferably also if they are identical, so that the user can see this explicitly), preferably near the date of grant, and preferably with a link to the Pre Grant publication, and similarly preferably in the database of Pre Grant publications preferably for patents that were granted there is preferably an indication (preferably at the top of the page) that it was already granted and preferably also a link to the granted publication. Similarly preferably within the page of the Pre Grant publication there is preferably also an indication if the application has expired without being granted and/or if it is still pending and/or preferably also if a CIP or CIPs or (for example continuation) were filed before it expired, preferably with a link to the relevant CIP or CIPs or other continuing applications, and preferably similar information is preferably available also for pages of published granted applications. Such information is preferably displayed at the top of The Pre Grant and/or Grant publication, so that the user can preferably see it instantly, instead of the prior art of having to search both in the Pre grant database and in the Granted database and having to search for continuity data in the relevant PAIR records. Another problem is that for example in countries where it is possible to file patent applications electronically (and/or for example by fax) the patent office web sites publish only the filing dates but not the filing times of applications eventhough the filing time can be determined exactly, so if for example two people file a similar application for example electronically in different countries and these applications are later published, at least the normal viewer cannot tell which of the two applications was actually filed earlier even if the time is known internally at the patent office, and also there are apparently no explicit rules that take into account the actual time of filing, at least in cases of contest or of earlier publication, where the timing can be critical to determine priority rights. So preferably this is improved so that patent offices publish also the time of filing at least when the filing was electronic and/or for example also if it was by fax, but preferably also when filing by paper, for example by improving the stamp to include also an automatic time stamp (for example by an electronic clock stamp), and for example in the USPTO where the filing date is considered to be the date of submitting to the post office if it is sent by express mail then preferably the time of the post office stamp is used for this in such cases. In addition, preferably the patent rules are improved to take into account the time factor at least in various cases of contest, so that for example if someone files an application for example at 23:00 UK time for example in the UK and someone else files a similar application for example in the USA for example at 20:00 US local time on the same date (which would mean for example that his/her local time of filing would be earlier than the UK filing but in fact in real time he/she filed it two hour later)—preferably the rules define specifically which application would be considered the earlier one for priority purposes, for example according to the relative local time of filing or according to the real (absolute) time of filing, which is more preferable since it is more fair that the application considered to be earlier will be the one that was indeed filed earlier in absolute time (in the example the UK application), or for example as long as it was filed on the same date both patents would be considered to have the same priority and thus for example must share revenues for the invention. Preferably such improved rules are included also in addition or instead in an international agreement, such as for example a revision to the Paris convention or for example to the PCT convention or other international treaties. Another possible variation is to extend this rule even beyond dates, so that preferably for example the rules of the local patent office and/or the relevant international treaty or treaties are preferably improved so that for example if it can be established that someone filed the for example UK application earlier in absolute time than the for example US application even if he/she got a later filing date (for example if the UK application was filed a few minutes after midnight), then preferably it will be considered as having been filed earlier then the other application even if the other application got an earlier date due to the time zone difference. In cases where the filing time is known for example in one of the countries but not in the other, preferably other relevant evidence or considerations are also taken into account, so that for example if one of the applications was filed in for example India and for example there is no exact time stamp then preferably the application is for example considered to have been filed between the morning to 15:00 pm, since patent can be filed in India only until 15:00. Similarly, such improved rules are preferably applied to cases of publication, so that for example if someone files an application for example in the UK for example at 1:00 after midnight on a certain date and then something gets published on the US for example 1 hour later, which is still one day earlier in the US local time, then preferably such publication cannot be considered prior art to the application since in absolute time the application was filed before the publication, and/or preferably similarly vice versa the rules preferably determine that the absolute time of publication is also relevant the other way around, so that for example if something gets published for example in a UK online newspaper for example at 1:00 after midnight in the UK and then for example someone files for example a provisional application of it in the US and gets a filing date of a day before the for example UK publication, then preferably this is still considered as having been filed after the publication, since otherwise that person could then file later for example an application for example in the US and/or in the UK, claiming priority of a patent that is considered to have been filed a day before the for example UK publication, while it was in fact filed after the publication. Another possible variation is that preferably when requesting priority documents preferably the issuing patent office can issue it in completely electronic preferably digitally signed form so that it can be sent instantly for example over the Internet preferably with sender verification, as explained also in other applications by the present inventor, preferably directly to the receiving patent office (preferably with automatic copy also the to user who requested it), and/or for example the digital signature with a preferably incrementing number and time and date stamp and preferably one or more CRC or similar digital fingerprints sufficient to ensure the authenticity because it can be verified against the relevant patent office server, and/or for example upon request preferably the priority document is created automatically for example in some special directory with a preferably automatically generated access string and/or for example with a password which is needed in order to access it, so that preferably the receiving office patent office can know that it is genuine simply by the fact that it appears on the patent office web site, while at the same time preferably no one without the access string and/or the password can access it. Another problem is that for example when the user requests real estate records from the government (for example Nesach Tabu in Israel) through the Internet, the relevant government office does not provide this as a certified and official copy, and for an official copy the user still has to order this on paper in the primitive traditional way. So preferably this is improved so that the relevant online government web site preferably can produce automatically a certified copy preferably with a preferably incrementing number and time and date seal and preferably digital fingerprints as explained above, so that preferably this alone is sufficient to verify the authenticity of the copy, and preferably both in this case and in the example of certified copies from patent offices, preferably the receiver can verify the authenticity for example by entering the relevant parameters on a server of the issuing office, so that the server preferably upon entering these parameters preferably confirms the digital fingerprints and/or displays a copy of the issued certified document online. A related problem is the fact that for example when buying an apartment in Israel the buying party cannot register instantly as the time of signing the deal a warning notice at the real estate registrar, so a crook might for example sell the same apartment multiple times on the same day, especially for example if it is done in the afternoon hours when the real estate registrar&#39;s office is closed. So preferably this is improved so that the relevant government site preferably allows users to register warnings online instantly at least temporarily, for example by filling in the correct identifying details and submitting for example a scanned copy of the relevant contract, however for security reasons preferably such a warning is preferably valid only for a limited time, so that for example within N days (for example 3-7 days or other reasonable time period) for example the registering user has to submit for example a notarized copy or at least the usual type of required paper documentation to the relevant government office in order to make the warning remain, otherwise for example the warning preferably automatically expires after this grace period. Another possible variation is that for example the court system computers are automatically connected to the registrar&#39;s site so that for example whenever there is a law suit involving a real estate property preferably automatic notifications are sent to the registrar and an automatic indication is preferably added about it in the registrar&#39;s record of that property so that when a user looks at the record he/she can preferably see immediately that there is a relevant pending lawsuit (and/or for example even closed lawsuits are listed), preferably with the reference to the exact lawsuit. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0116]    Another possible variation is that preferably the search engine can also use preferably various heuristics for determining the information value of the search results, which can be used for example for improving the ranking of web pages according to their information value and/or for example indicating near each link its information value (for example as a single score and/or as a list of scores and/or sub-scores). The information value scores can be defined for example according to authoritativeness (for example a scientific journal article versus a blog page), truthfulness, objectivity, expertice, reliability, accuracy, etc. Preferably the search engine can determine for example if a web page is probably more scientific (for example has higher information value according to one or more of the above criteria of information value) for example according to for example diagnosing automatically whether it contains references and/or how many references and/or how scientific are the sources that are included there, and/or for example by lexical and/or semantic analysis of the details about the author if such details exist, such as for example if he/she has a PhD. title and/or has a background relevant to the field that the article deals with (for example the writer has a degree in nutrition in an article about the dangers of eating Soy products), and/or for example link structure (incoming and/or outgoing) that indicate that the page (and/or the site in general, i.e. for example the entire domain or for example subdirectories in it) has links to and/or from other pages (and/or sites or for example subdirectories in them) which are considered more scientific (or of higher information value) by the system (for example in terms of percent of scientific incoming and/or outgoing links and/or in terms of absolute scientific incoming and/or outgoing links), and/or for example if the site is for example on a university or for example in a government institute (for example according to the top level domain—for example “.edu”, “.ac.&lt;country code&gt;”, “.gov”, etc.). (However, a university site can contain for example also student pages, and government sites can carry for example tendentious or biased information sometimes, so preferably the search engine takes into account for example also how high the page is in the subdirectory structure of the domain—for example student pages will typically be in a lower directory, many times for example with a name that contains a ‘˜’ on the path, and for example if a page in a government site appears to deal with a scientific subject preferably the search engine can assume that there is less chance for bias than if the subject is political for example). This can be done for example preferably in a way similar to the way that Google uses recursively the number of incoming and outgoing links to determine the authoritativeness of pages and/or sites (where authoritativeness is actually defined by popularity), except that in this case preferably the recursion uses as criteria also for example various indications about the scientific value (or information value) of the pages and/or sites and/or sub-areas in the sites, etc. Determining the initial indications can be for example according to various heuristics based on the content of the pages (for example as in the above examples), and/or for example additional indicators, such as for example starting out with known scientifically accredited sources, etc. (However, these indicators are preferably reassessed automatically again for each page and/or domain and/or directory tree or sub-tree, in order to avoid degradation of the information value score or scores as the recursion continues). Preferably the taking into account of the information value can be for example applied automatically as an improvement of the results ranking algorithm and/or for example the user can indicate that he/she prefers to take this into account, for example by marking default preferences (which are preferably saved for the next time he/she uses the search engine, for example in cookies) and/or for example by adding some special keyword or mark to the search string, and/or for example the search engine has a few search windows, so that one or more are defined in advance for searches for more official and/or authoritative and/or scientific information, etc., and/or for example the search engine can preferably decide automatically how much weight to give to the information value of the results according to the search string itself, so that for example if the user enters a search string such as ‘blond huge boobs’ then he/she is probably not looking for scientific articles in this search. However, since it is obviously difficult to know if the user is for example searching for articles about cars or sites that sell cars (for example with a search string like ‘best price performance cars’), the above described solutions of using semantic qualifiers, such as for example ‘best price performance cars (shops that sell)’ when looking for shops and for example ‘best price performance cars (articles/reviews)’ is more preferable, and preferably the search engine can use any of the above methods for responding to such a query (such as for example synonyms, semantic trees and/or taxonomies, semantic tags, etc.). Of course for example in the variations where the user chooses in advance more official and/or authoritative and/or scientific information, etc. (for example by adding an indication or choosing the appropriate search window, as described above), preferably the search engine can for example automatically ignore sources or results (for example pages and/or sites in general, i.e. for example the entire domain or for example subdirectories in it) which have an information value below a certain threshold, or for example mark or indicate the threshold (for example by a clear borderline or in a separate window), so that for example results below the threshold are displayed in a separate section or window. Preferably this procedure is done both for normal web pages and for internal search databases (the deep web), which is hundreds of times larger than the normal web. In this case it is even easier to reuse the indicators to avoid degradation, since internal search databases typically have a consistent nature and typically have clear indicators about their scientific or information value, such as for example what organizations stand behind the database, what type of sources are included in it, etc. Preferably the search engine can also automatically include in the search results also replies from various internal search databases, preferably by analyzing automatically the search keywords and/or semantic qualifiers, so that for example a semantic qualifier such as “(articles/reviews)” preferably prompts the search engine to try to bring some results also for example from relevant internal databases. Another possible variation is that for example when searching for academic results and/or for example in normal web searches, the user can for example request the search engine to show only results from articles (and/or for example normal web pages which were last updated) for example from a certain date onward or for example before a certain date or for example within one or more range of dates. However, some pages include for example an automatic visitors counter and so the counter is automatically updated even if the page does not change for years, so preferably the search engine uses its historical data to estimate if the amount of change and/or the type of change justifies regarding the page as recently updated (for example addition of new paragraphs or significant changes in existing paragraphs, as compared to merely updating a few numbers). (Another possible variation is that for example the web server sends also data about the last time the page was updated in the local directory, but that is much less preferable since page owners can easily write a program that will update the file&#39;s date regularly even if there is no real change). Another possible variation is that the search engine can for example use the historical data to answer for example queries such as when is the first time that a certain combination of words appeared together in the same web page (preferably the user can for example ask this directly or for example requests the results to be sorted by date). Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0117]    Another preferable variation is that for example the system includes a firewall which allows giving specific applications differently rights for downloading and/or uploading information for example to or from the Internet (and/or for example through all available communication channels or through specific communication channels, such as for example network cards, USB, wireless, modem, etc), in contrast to prior art firewalls which only allow users for example to let applications access the Internet, but the user has no knowledge or control for example if an application that has been allowed to access the Internet is uploading or downloading information, etc. This is very important since for example the user might want to allow a program such as Winamp to access the internet for example in order to play streaming data but does not want Winamp to be able for example to upload information, or for example the user might want Word or for example some other word processor to be able to access web pages but does not want the word processor to be able to upload document files (for example even if they are in its own directory and/or even if it is the current file which the user is working on), so that for example if an application is actually a Trojan horse that tries to steal data or for example the application is compromised for example by some buffer overflow, it will not be allowed to steal data and send it out. This can be done for example by automatically showing the user the statistics of sending/receiving information near each application that has been allowed to access the Internet (for example in some table, preferably in the same normal table of authorizations) and/or for example defining a maximum ratio between upstream and downstream for each application (which is then preferably enforced automatically for example by automatically blocking excess uploading and/or warning the user and/or asking for his/her authorization) and/or for example defining a maximum absolute amount of information that can be sent out per time (which can be for example enforced similarly). However, such definitions are limited in effectiveness, since a sophisticated hostile application can for example slowly steal important data over time even within the limitation and/or for example various applications might cease to function properly because of these limitation. For example, enforcing such separation between uploading and downloading is not easy since even programs that download data typically have to also send some information in order to establish the communication, however allowing for example automatically a reasonable required ratio between the two directions can solve this problem and this can be quite effective for detecting theft of data, since if a program for example is allowed to upload only for example ¼ or 1/10 or less of what it downloads then trying to steal for example a large file will also require the application to download even more data and the user can easily see for example that the application had no reason for downloading it (and this is only if the Trojan knows for example about the limitation and tries to cheat its way out of it by downloading extra data, otherwise it will simply be blocked because it would try to send much more data than it receives). Another possible variation is for example monitoring the data in the incoming and/or outgoing packets, but even this can be limited in value since for example a hostile application might encrypt the data and/or for example disguise one protocol within a seemingly different protocol, etc. Another possible variation is that for example programs that the user wants to allow only to download data but not upload data are automatically prevented from any real access to the web and for example the OS and/or the firewall and/or the security system intercept any attempt that these application make to contact the web and send the requests instead, and so for example only valid normal protocol requests for example for accessing web pages and/or for downloading data, etc., which are recognized by the firewall or other intermediate agent are allowed to go through (this means of course that the firewall or other agent preferably has in this case to monitor the entire incoming and outgoing protocol of that application in order to be able to understand fully what is going on and interfere when needed). Another possible variation is that for example the firewall and/or security system can display also for example upon user request for example a sorted list or table of the programs that are currently downloading the biggest amount of data and preferably separately the list of programs that are currently uploading the biggest amount of information and preferably also the file names and/or directories (preferably by monitoring the files which these applications read or write and/or the packets that they are transmitting and/or receiving. Preferably the firewall or other agent for example can also notice other suspect behaviors, such as for example requesting a web page with an unreasonably large parameters line for example after a “?” in a url (for example ‘http://abc.com/test?asdo+32892323+8238023803+wqwqdpq? ideeww . . . ’), since such addresses can also be used for example for connecting to a hacker&#39;s site (phoning ‘home’) and stealing the data in disguise of the url&#39;s parameters, or for example frequent repeated similar connections for example with shorter parameter lines that keep changing (in case the data theft is in smaller stages, etc.). Similarly, for example the TCP/IP protocol itself might be changed so that for example sockets can be opened for both sending and receiving data or only for sending or only for receiving. In addition, preferably the firewall (and/or for example the Security system and/or the OS or other software) for example can also indicate to the user automatically when some application (for example that has been allowed to access the web) is trying to download a file (so that for example the user can be alerted if such activity is happening without his/her requesting it—preferably together with indication of the full path and the file name that is being downloaded), or for example the user is warned for example only if an apparently executable file is being downloaded. Preferably the firewall (or other agent) can determine if it is an executable for example not only by its extension but also by automatic inspection of its contents, since a hostile application might for example use a seemingly innocent extension and then for example rename it, etc. This can be very useful for example in cases of various browser exploits which cause the browser to download hostile executable code without the knowledge of the user. Another possible variation is that the user is for example warned automatically (preferably with request for authorization) for example every time a program modifies and/or erases and/or creates an executable file on the disk (This is something that should normally happen only if the user compiles a program or if he/she downloads an executable file) and/or for example whenever an executable is installed. Another preferable improvement is that for example the firewall allows the user to change the permissions of multiple applications at the same time for example in the firewall&#39;s table, for example by marking entire columns or other areas and then changing automatically for example all the permissions in the marked areas, such as for example to allow/deny or ask, etc. Another possible variation, which can help the user notice for example inadvertently given permissions, is that for example whenever a program that has been given the rights to act as a server becomes active or activates the server preferably for example the firewall notifies the user that the server is now running and accepting connections from the internet and/or for example very time the user is shown the browser&#39;s table of permissions the active servers are preferably marked preferably very conspicuously. Another problem with personal firewalls, such as for example Zone Alarm, is that there is usually a large number of dll&#39;s and/or other components which are used by applications that are allowed to access the web, and some hostile application (for example a virus or Trojan horse) can easily change one or more of these components and thus actually for example create a huge hole in the firewall. For example Zone alarm does not notice any such changes and simply asks the user to allow only components which he/she trusts, but of course it is unreasonable to expect the user to now which components to trust or not. So preferably at least one of the following things are done to protect against such tempering: 1. One possible variation is that Preferably the firewall and/or security system can automatically check for example in some Internet database or databases (preferably only in specific certified sites) the correct CRC (or other fingerprint or fingerprints) of the various known components and thus determine automatically if some component is suspiciously with a wrong fingerprint (this is especially useful for example fore components that were on the computer before the firewall was installed). Preferably the database checking includes also a lookup for example in some preferably encrypted database or databases of the OS, in order to check that relevant OS components have not changed, and/or this check is also conducted for example on the Internet database or databases. 2. Another possible variation is that preferably when such a component is changed the firewall and/or security system warns the user about it and preferably is also able to tell the user which application changed it and when, for example by automatically monitoring all the components that are used by the programs that have been allowed access to the web and warning the user for example when they are changed and/or for example the next time the relevant application that uses the changed component tries to access the web, and then preferably the user has again to decide if to allow the application which uses the changed component or components to access the web. However, it is much more preferable that the firewall and/or security system actually intercepts the change at the moment that an application is trying to make it and asks the user if to allow it before the component is allowed to be changed, and, since the firewall preferably tells the user which program is trying to change the component, the user has a much better chance of being able to distinguish between a legitimate change (for example because he is installing a new application) and a change attempted for example by a virus or Trojan horse. Another possible variation is that for example the firewall and/or the security system can be set to require user permission for example the first time a program (and/or for example dll or driver) tries to access each file type (for example “.exe” files, “.doc” files, “.vob” files), and preferably for each file type the user can for example decide if to allow the program read rights and/or write rights in such files (and/or for example execution rights separately, and/or for example creation rights and modification rights separately, and this can be done for example in addition to or instead of requesting permission according to directories). However, in this case preferably the system automatically differentiates between access to shared OS directories and files (which preferably by default are handled automatically by copy-on-write of files or sub-file parts, as described for example in U.S. application Ser. Nos. 10/301,575, 10/644,841 and 10/968,022 by the present inventor), and attempts to access other directories or files which were added by the user or by other programs. In this case preferably the user can view for example in the table of authorizations which applications (and/or for example drivers or for example dlls) were allowed such rights (for example in addition to showing internet access rights). Another possible variation is that the user can for example also view for example a table which shows for example according to file type and/or for example according to directory and/or for example according to other resources (for example according to various peripheral devices) which programs and/or drivers and/or environments and/or guest OSs are currently allowed access it and/or with what type of access). Another possible variation is that the security system can for example enforce segregation of the computer into two or more virtual machines or virtual environments for example based on the user marking one or more specific directories or for example one or more specific partitions (or other areas) as protected, but preferably the user does not have to jump between the machines, so that the protected directories and/or partitions are actually preferably enforced by a virtual machine with copy-on-write (preferably on a level even lower than complete files), but access to the protected areas for example in order to copy a file into there is preferably based on determining if the user or the application initiated the access, as explained in the above applications, or for example the user has to enter a special mode in order to move or copy files within the environments. So in this variation preferably if the user for example clicks on Word on the desktop and then for example opens a file in the protected area or areas (or if the user for example clicks on the word document directly if the document is in the protected area or areas), preferably this automatically activates instead a separate copy of Word which is associated with the protected area (preferably based on copy-on-write), since otherwise it could be very dangerous since for example a Trojan in the unprotected area might compromise Word in the unprotected area and then if the user opened the protected file with that copy of word anything could happen. (This problem does not exist if automatic segregation with an unlimited number of virtual environments is used, as explained for example in the above applications, since in that case Word is also protected automatically from Trojans). So if for example a Trojan horse compromises for example Word, if the Trojan is executed outside of the protected areas it is preferably able to affect only the Word of that environment (preferably by enforcing copy on write), and if the user wants to make changes for example in the version of Word that is used in the protected area or areas, he/she has to run for example the program that updates Word from one of the protected areas (preferably the user can define of course for example if the protected areas will have a shared virtual environment or each an environment of its own). This is better than the solutions where the user has to jump between two or more virtual machines since this way there is much less change from the normal user experience, and also there is less chance that the user will make errors and for example think by mistake that he/she is in the a protected environment while he/she is not or vice versa. Another possible variation is that for example the user jumps between the environments but for example copying files between them is based at least partially on at whether the user initiated the command, so that the copying between the environments becomes easier for the user. Similarly, for example in Microsoft&#39;s Virtual PC or similar applications preferably the user can for example directly copy files into the virtual disk of the virtual OS (but preferably only when activated from outside, so that preferably no program from the virtual Os can access files outside the virtual OS), so that for example the user can preferably for example drag and drop files for example from the normal explorer for example onto a representation of the virtual hard disk for example within the virtual C console or for example over the desktop or some other point in the virtual OS, and/or for example Virtual PC can add for example to the normal explorer of the host OS for example one or more drives which represent the one or more disks of the virtual OS, and/or for example the user can for example copy directly files from a DOS or CMD window onto one or more drives of the virtual OS for example by using one or more letters assigned to them or for example by adding one or more characters for example before the drive letter name which indicate that this is for example a drive in one or more virtual OSs and then preferably for example the Virtual PC program or the OS interpret this as a command for example for the Virtual PC application to copy the file into the desired virtual disk. This is much more efficient than the current way in which the user can typically transfer files form the host OS to the virtual OS only through diskettes or through burning CDs. Preferably the user can similarly also copy back files from the virtual OS into the real OS, for example by any of the above methods, for example by dragging in the other direction or by reversing the source and target for example in the CMD copy command. Another possible variation is that for example when creating the virtual OS the user can tell for example the Virtual PC or similar application which files and/or directories and/or even for example entire partitions or drives to copy into the virtual disk. Of course preferably both when creating the virtual disk and when copying files or directories into it afterwards preferably this is based on Copy-on-Write, as explained elsewhere in this application and in previous applications of the present inventor, so that until a change is made preferably only a logical link to the original file or directory is created. Preferably there are at least two types of virtual copy or virtual sharing available based on copy on write, so that for example the virtual OS can see the copied files or directories as existing in the external location (typically useful for example for large directories or large files or complete directories or for example entire partitions which the user wants to virtually share with the virtual OS) or for example see them as if they were copied to one or more virtual disks or partitions or directories within the virtual OS (typically useful if the user wants to virtually copy to the virtual OS for example only some of the files in the directory or for example wants to feel more clearly and/or differently that this is only the virtual copy when working in the virtual OS). If for example only the changed part of a file is copied during the copy on write, preferably the virtual OS continues see for example an integrated view of the file in which for example local changes that were made in the virtual environment are super imposed on the view of the latest version of the real file which can continue to be updated, so that for example if the file is an address book for example with names and phones and/or addresses and for example the user adds one or more addresses in the virtual copy and for example later adds other addresses in the real file, then preferably the view in the virtual file automatically shows both the local additions or changes and the for example additions and changes that were later made in the real file. Preferably the user can choose for example when virtually sharing a file with a virtual OS if the shared file for example will continue to appear to the virtual environment in its continually updated form or only in the state it was at the time of the first copy on write, and if the second option is chosen (which is preferably the default for example for system files) then preferably either the file is copied completely to the virtual OS or more preferably there is kept at least one real copy of the file before any changes. For example in a system with multiple OSs with a hypervisor and hardware support such as for example vanderpool, if at least one same OS is shared with one or more virtual environments of the same OS then preferably there is a basic state of the OS which is considered the starting point and for example changes to system files in each virtual OS are preferably based on copy on write relative to that state, and so if there is for example at least one instance of that OS which is considered to be the real OS or superior to the virtual OSs of that same OS, then preferably changes in its own system files are based on cumulative changes in another copy of the original state (which is more wasteful of space but adds another level of backup), or for example they are also based on copy on write of the original state. If the user for example shares one or more directories or partitions also for writing between multiple OSs in a system for example with vanderpool and a hypervisor, so that preferably all the sharing OSs see the same changes in those directories or partitions when one of them for example changes one or more of the files in them (i.e. these are for example directories or partitions to which the multiple OSs have real access), then preferably at least in one mode there is a different indication for example near the file or directory or partition, for example when the user is working on such partitions or directories or files from the sharing OSs, if this is real sharing or virtual sharing or if this is sharing also for writing or only for reading, so that preferably the user has a clear indication if changes that he/she makes will affect the real file or only a virtual copy of it, and/or for example at least if the user is about to change files which are considered to be highly important (for example as defined or determined by the user and/or by the OS, for example as explained also in previous application by the present inventor) then preferably for example the host OS or for example the hypervisor can for example issue a warning if the user is about to change a real copy of it. Another problem for example with Microsoft&#39;s Virtual PC 2007 is that if the user installs the virtual machine additions for example on a virtual Windows 98se in order to enable pointer integration (so that the mouse can move smoothly between the host OS and the virtual OS&#39;s windows—like with any normal window on the guest host), at least in the Hebrew enabled version of Windows 98se this creates a problem of fonts disappearing for example from the Windows Start menu and from the login prompt during booting, and also according to the instructions of the Virtual PC software various programs in the virtual OS are not compatible with this, and on the other if the user does not install it then the user has to click first inside the window of the virtual OS in order to start a virtual mouse pointer (typically the normal mouse arrow) within the Window of the Virtual OS, and for going back with the mouse outside of the virtual OS window the user has to click on the Right Alt key, and in addition the position of the mouse&#39;s pointer typically jumps when switching between the two states in a way that is counter-intuitive and annoying, and also in this case the mouse pointer moves considerably slower within the virtual OS&#39;s window. So preferably this is improved so that if the user installs the pointer integration at least fonts in the OS menu are not affected by this, and there is no reason why this should be affected since preferably the point integration works by simply capturing the physical mouse below the virtual OS and letting the virtual OS interact with a virtual mouse controlled for example by the host OS (or by the hypervisor if this is implemented for example with the vanderpool technology), or for example by a thin layer that simply transforms the mouse coordinates to the range needed to fit within the borders of the virtual OS (for example constantly or at least at the instant of transferring the control of the mouse to the virtual OS), and if the user does not install the point integration then preferably the guest host at least monitors for example the mouse movements in the virtual OS and so for example if the user continues to drag the mouse at one of the borders of the window of the virtual OS preferably the host OS can preferably immediately sense this and thus let the user exit with the mouse to the host OS even without having to click on a special key (such as for example the right Alt key) for that, and preferably this way the host OS can also show the mouse pointer automatically in the correct next position instead of jumping into a different position. Similarly in systems where for example there are multiple OS&#39;s for example based on the vanderpool technology, especially for example in they have an equal status, preferably when switching between OS&#39;s the mouse&#39;s cursor preferably stays at exactly the same position, just like switching between normal windows, preferably at least for example by the hypervisor making sure that when transferring control to another OS the mouse cursor initial mouse coordinates are so that it will remain in the same absolute position on the monitor. If the OSs for example all use full screen mode, preferably the coordinates remain correct even without this intervention while switching, however if they use different resolutions then preferably this intervention is still done. However, if there are multiple OSs which do not have the same resolution then preferably the monitor remains with the highest resolution and creates the lower resolution in the OS or OSs with the lower resolution by emulating the lower resolution (preferably for example by automatic scaling preferably with a DSP in the display card, and preferably both if the OS is in full screen mode and if it is in partial size mode like a partial size window), so that preferably there is no blacking out of the OS for changing resolution and/or refresh rate while switching between such OSs, as explained also elsewhere in this application. Another possible variation is that for example when looking at the authorizations table of the firewall preferably the user is shown also for example which programs have been given temporary access rights to the communication channels (i.e. preferably the user is shown both an indication what permissions were given to each program and if they are temporary or not, for example by a visual indication near each application or for example by using a separate table or area for temporary permissions), and preferably also for example how long ago the temporary or non-temporary permission was given, and/or how much data that program has already sent out and/or for example received, as explained above, etc. This is different from the prior art, in which for example the very popular ZoneAlarm firewall shows near each program an ‘X’ if it is not allowed to access the Internet, a ‘V’ if it is allowed, and a ‘?’ if it needs to ask permission (i.e. the user has not asked to remember his last reply), so if the user gives a program a temporary permission, the authorization table still shows a ‘?’ near that program and the user cannot know if the program has or doesn&#39;t have temporary access rights at present. This is dangerous since the user might inadvertently answer a prompt from the firewall without paying attention and thus give a program for example temporary access right without intention, but when looking at the authorizations table the user has no indication of this. Another possible variation is that the user can preferably for example press some control key or for example click on some icon or menu option in the firewall which can preferably for example automatically for example preferably instantly block all the temporary permissions as if all of them were denied and for example leave them blocked and/or for example preferably also reset all the temporary permissions so that the next time such a program tries to access the network the user is asked again. In addition, preferably the firewall can show in these statistics also for example a table of IP addresses and/or for example urls for example with the aggregate amount of data sent to each of them for example by a specific application for example over a certain time period, and preferably unlike for example the Comodo firewall (in which once a connection is closed it disappears from the table, or if the applications is closed all of its connections disappear and the user might not even notice for example that it sent out a large amount of data), preferably when connections are opened and then closed (for example from the web browser or other application) preferably a closed connection does not disappear but can still be viewed at least for example by clicking on some icon or menu option, and preferably the user can also view for example currently open and/or closed connections for example sorted by the amount of data uploaded or download (preferably separately for download and upload). However, preferably the firewall or the security system preferably warns the user automatically when unusual behavior occurs such as for example sending out unusual amounts of data, as explained also by previous application by the present inventor. Another problem is that for example when a firewall such as for example Comodo warns for example that a certain application (such as for example MSIE) for example tries to use Explorer through OLE automation or though other means for example in order to communicate to the Internet for example though some other application (such as for example the Opera browser), if the user does not allow it then the firewall blocks the entire other application that has been accessing the Internet (for example the Opera browser in this example) from accessing the Internet, i.e. for example all of its currently active tabs become blocked and the user for example has to close the browser and reopen it. So preferably this is improved so at least as one of the options and/or for example by default, if the user does not allow it than preferably the firewall specifically blocks only the specific tab or connection related to this activity when possible and/or blocks only the ability of the offending application to connect to the browser or use it in such a way and does not block the entire browser. Another possible variation is that the firewall for example includes also a preferably instant undo and/or redo function, which can preferably also show the user for example all the recent permissions or changes he/she has made in the firewall (since preferably the security system and/or firewall keeps automatically a log of all the questions that the Security System and/or firewall asked the user and his replies, as explained in other applications by the present inventor) (for example by answering a question that the firewall posed or for example by clicking on the table of authorizations) and the user can for example instantly undo the last action or actions for example by changing the reply and acting accordingly. Preferably the user can either simply recall the last question and answer it differently (in which case preferably the firewall preferably immediately suspends again for example the Internet access or the relevant process or application until the user answers again the question), or for example enter the log which shows his/her recent answers and then choose for example the last answer and change it (this is preferably done for example by pressing some instant-access control key or for example by clicking on a preferably top-level menu option which enables this preferably instantly, so that the user can for example un-allow something preferably within seconds or less for example as soon as he/she realizes that he/she for example allowed something by mistake). (Of course this preferably includes additional actions which the user can allow or not allow and not just accessing the Internet, as explained in other applications by the present inventor, and this can be used similarly also for example with the UAC of Vista). Another possible variation is the preferably for example the OS and/or the dialer and/or the security system and/or firewall (and/or any other program) preferably keeps also a history of previous Internet connection sessions (for example unlimited or for example for a certain time limit or till certain list size and/or for example until the user explicitly deletes some earlier history), which can include for example start time and end time of the connection, duration, how much data was sent out, how much data was received, and/or for example how the sent-out and/or received data was divided between the various programs, so that for example for each session or time period requested the user can be shown for example a sorted table of the programs that sent most data out and a preferably separate sorted table of the programs that downloaded the most data, preferably with the name and path of each program and the amount of data downloaded or uploaded (and preferably also for example the list of files associated with these downloads or uploads, preferably according to which program uploaded or downloaded them). 
         [0118]    Another possible variation is that better precautions are taken against buffer overflows, for example as follows: Although Microsoft has added the prevention of data execution, both by software and/or by hardware to the recent XP service pack 2 in the 2 nd  half of 2004, however the problem still remains that even with this improvement, according to http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2mempr.mspx, typically attempts to execute code from the data area may still cause the process to terminate and/or even cause the system to fail with Bugcheck. This indicates also a deeper problem, which is that even just data crashing can be dangerous, such as for example in case of changing the return address, or for example if various data that may include for example information about file names or disk segments or web addresses or user permissions is crashed, etc. Therefore, in addition to the above, preferably the security is improved so that even data crashing becomes automatically impossible or at least much more difficult to do. This can be done for example by improving the compilers to perform much better automatic checks and preferably automatically add (for example preferably for every type of reading data for example from a user interface or from a file) additional code that automatically cuts off any data that exceeds the size of the input buffer, for example in a way similar to the way that Pascal compilers automatically add code that cuts the data that can be read into a string when it reaches the size of the string, except that this is preferably done for example also in C compilers and preferably for every possible type of data input an not just strings. Another possible variation is that the security system and/or the OS can for example analyze executable files that have already been compiled or for example were written in assembler and preferably identify automatically problem areas where for example buffer overflow may occur and preferably automatically add code that can prevent it and/or at least for example issue an automatic warning about such vulnerabilities, and/or for example at least the data stack is better protected by any of the above methods and/or for example by automatically keeping return addresses at a separate place from the data (and if in some cases executable code is also kept in the stack then preferably these executable codes are also preferably automatically kept in a separate place from the data). Of course keeping the return addresses at a separate place from the data for example in stacks can be most easily done for example by changing the compiler to work this way, but preferably this can be done also for example by a program that goes automatically over executable code and can preferably identify for example the commands that add the return address to the stack and can preferably automatically change the code so that this is kept and handled separately. Another possible variation is that for example the OS or the security program preferably automatically creates for example a fingerprint of any executable code loaded in memory for example when the user runs any file from the disk and preferably marks all such code as authorized to run and can preferably intercept and request user authorization automatically for example whenever the code changes or whenever for example new executable code appears which had not been normally loaded when the user runs a file or for example which had never been run before on the computer. Another possible variation is that preferably such fingerprinting and/or marking of executable code is preferably also at least partially hardware based for example by adding at least some of these features in the processor itself and/or adding for example the ability to create automatically interrupts related to this, so that this can work much more efficiently. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0119]    Another preferable improvement is that the user can have for example two or more Operating systems running at the same time (for example Windows Me and windows XP or XP and Longhorn), so that the user can for example jump between them preferably instantly or almost instantly, for example by pressing some key or key combination or clicking on some icon, instead of having to shut down Windows and reboot. This is preferably done for example by keeping a mirror image of the loaded and running OS (for example like in sleep mode, which means that while the user is in one OS the other OS is dormant or simply the user can switch between the OS&#39;s after entering sleep mode), or for example by having preferably separate swap files so that both Operating systems can be actually running at the same time—which means that preferably one or more additional OS elements are operating below the two (or more) Operating Systems and are in charge of the resource sharing between them. As explained above, this is preferably done together with copy-on write so that only the changes between various instances of the same OS are saved, and of course it can be done more efficiently with a processor that is especially designed to support it, such as Intel&#39;s Vanderpool, but using such special element or elements bellow the running Operating Systems can work also with a normal processor. (However when Copy-on-Write is used, for example for complete files or for parts of them, preferably at least once in a while preferably more complete copies are also preferably automatically kept, for example like a base-frame in Video, in order to prevent the danger of corruption due to a even single error on the way). Vanderpool uses an additional more privileged ring below ring 0 for the control system below the OSs, however this was described for example in U.S. application Ser. Nos. 10/301,575 and 10/644,841 by the present inventor a long time before Intel started to talk about this (first priority was on April 2 and Apr. 8, 2002). In addition, as explained in those applications, there can be a special more privileged area or areas within ring 0 or for example below ring 0. In other words, there can be even one or more additional higher privileged areas or rings or sub-rings with even higher privileges, for example in addition to ring −1. For example (instead of one control system, for example in ring −1, which for example can take care of both running for example 2 or more OSs or virtual machines which the user can switch between and the security for each OS or virtual machine and/or also the security within each OS or virtual machine, such as for example enforcing automatic segregation between programs within that OS), there can be for example a separate control system for each OS (which for example runs below the OS, for example in ring −1, and for example takes care of the security within that OS, such as for example enforcing automatic segregation between programs within that OS, and/or for example takes care of any other desired control system below that OS), and for example an even more privileged control system, for example in ring −2, which for example takes care of the context switching and/or security between the OSs. However, since typically the user might want to enable at least some file and/or directory sharing between the various OSs, it is more preferable that the same control system and/or security system indeed handles both the security between the OSs or virtual machines and within them, since otherwise a security system which runs below the OS but is not aware of the context switching between OSs might for example become confused or even for example might misbehave for example by assuming that some change (made for example by another OS) was created by hardware malfunction or unknown type of attack and for example might restore it automatically (for example if it guards changes in some files or directories with redundancy), or for example another OS might for example damage a special file system run by the security system of a separate OS or for example confuse the user for example by showing him special files and/or directories which are used by the security system of the other OS but for example are not normally visible to the user. Another possible variation is that there is for example a system of privilege rings also on additional devices other than the CPU, such as for example the hard disk (in which case it is preferably implemented for example by a ring structure on the processor of the hard disk&#39;s controller) or for example on disk-on-key devices (such as for example those that connect to USB ports) or other devices, so that preferably for example the hard disk enforces through hardware support for example that only processes running at ring 0 can in the computer&#39;s CPU can for example write to the FAT area or for example can access other highly strategic areas on the disk, or for example only processes running at ring −1 can for example have special access rights to the disk. Preferably this is accompanied also by hardware enforcement along the communications channel between the disk or other device and the CPU, so that for example the chipset allows for example certain commands to be transferred for example only when the CPU runs for example in ring 0 or for example in ring −1. Another possible variation is that for example various protocols are defined for better cooperation between the OS s and/or their security systems so that for example there are standard mechanisms for letting each guest OS and/or its security system know that it is being used in a multi-OS environment and/or for example which directories and/or resources can be accessed by other OSs and in what type of access. Another possible variation is that the security systems ask the user before making such automatic restores and so the user can easily know for example which changes he/she made from another OS and wants to keep. Another possible variation is that in this mode for example certain functions are automatically disabled or are available to only one OS (for example by choice of the user and/or by automatic choices), for example when there are problems of allowing two or more separate processes to access the same hardware at the same time. Although there are for example systems that allow the user to run a window of another OS by emulation, this is much more efficient. Another possible variation is that for example if the graphics card can support two or more monitors at the same time and the user connects two or more monitors, preferably the user can for example tell the control system which is in charge of switching between the OSs, preferably as one of the available options, for example to run on each monitor a separate OS at the same time. Another problem is that in Windows for example if there are two monitors connected or one monitor connected only to the 2 nd  monitor socket of the display card and the user for example installs a new OS or a new display driver while using the monitor that is connected to the second socket, on the first reboot the system forgets this and tries to start working only with the first socket (eventhough the 1 st  socket might be for example not connected or connected to a monitor that is turned off), and then the user has to connect the monitor to that socket in order to fix this. So preferably this is improved so that the new driver or OS remembers which was the active monitor before and thus preferably keeps using the same monitor after rebooting unless the user changes it himself/herself afterwards. Another possible variation is that preferably the OS and/or the display card can preferably sense automatically preferably on all of the display connectors preferably if a monitor is connected and turned on (since otherwise it does not get any response from a monitor on that connector), and so if for example there is a turned-on monitor connected only to the second socket then preferably the OS and/or the display card know this and preferably switch automatically to the connected and working monitor. (Another possible variation is that the display card can for example sense also if a monitor is connected to a socket but not turned on (for example by sensing a change in electrical or magnetic inductance or by other means), but that is less important). Another problem for example when installing windows Vista is that for example when the OS enters the stage of “Completing installation” a long time can pass without any indication of what is really happening and the user does not know for example if there is any problem. So preferably the installation sequence is improved (for example in this and/or in other stages that take more than a certain time), so that preferably the Os displays much more information about what is going on, preferably based at least on general categories of actions, and/or for example based on the time that has passed, so that for example at least once every minute (or other reasonable interval the) OS preferably automatically gives more details about its current actions. Another possible variation is that for example when there are multiple OS&#39;s running which are for example switched-between by a hypervisor for example in ring −1 or lower, if one of the OS&#39;s needs to reboot, preferably for example the hypervisor can keep for the OS&#39;s a buffer or buffers of various states of various hardware devices, so that preferably it can simulate for the rebooting OS a situation with the appropriate values that would be returned from these devices if they had really been reset by a boot but preferably without having to actually reboot, so that preferably the others OS&#39;s can keep running undisturbed at the same time (for example by monitoring and saving these parameters during the real boot and then repeating those conditions in the virtual reboot). Another possible variation is that for example if new devices are added for example without rebooting, for example by connecting the to the USB, and/or for example new device drivers are added which need to be recognized by already running applications, preferably the relevant OS can for example identify automatically only the affected running applications and then preferably for example save their current state and then close and reload them automatically without rebooting and without affecting other running applications. In addition, since Microsoft are adding for example in Vista a restart manager, which can also prevent at least some reboots when they are not really necessary, preferably if an installing program tells the user that he/she needs to reboot, preferably the OS itself can for example interfere when the reboot is not really needed and for example display to the user a message to ignore the reboot suggested by the installing software since it is not really necessary, or for example the OS can automatically cause the message that tells the user to reboot for example to become invisible. This can be done for example by preferably monitoring automatically what the installing program changed (and then preferably doing what is needed in order to enable the change without the need for reboot, when possible) and monitoring the messages that the installing program tries to display to the user and intercepting the message if appropriate). Another possible variation is that for example in such multi-OS environments when the user activates hibernate or standby or even shutdown from one of the OS&#39;s, preferably the hypervisor simulates this only for the relevant OS, and for example real standby or hibernate or full restart or real shutdown has to be activated from the level of the hypervisor. Another possible variation is that preferably in systems that run multiple-OS&#39;s, preferably unless for example some resetting has to be done to some hardware element, preferably for example the hypervisor preferably ensures that only the relevant OS&#39; actually reboot while the other OS&#39;s keep running, and for example if a real reboot is required for hardware reasons then preferably the hypervisor interferes and asks the user&#39;s permission. Another possible variation is that in systems where multiple OSs run concurrently with a hypervisor, preferably the user can for example instruct the hypervisor to have a special link with one (or more) of the OSs, so that this OS becomes a master OS and for example can provide various services for the hypervisor, thus enabling the hypervisor to carry on various additional activities which would normally be performed by an OS (of course this can be easier if more than one ring exists below ring 0, as explained elsewhere in this application and in the previous referred applications), since then for example the master OS can run in ring −1 and the hypervisor can run for example one ring below it). Another problem for example in windows Vista is that if some application is not compatible with the AERO graphics then the entire user interface is converted to normal (“classic”) user interface, which means no preview windows and less animation and no glass effects—until that application stops running. So preferably this is improved so that even if some application&#39;s graphics is incompatible with the Vista graphics, preferably its output is automatically translated or converted preferably on the fly to an output which can be displayed through the AREO vista graphics and thus can be combined with the input of other programs which work with the AERO graphics. There should be no problem to do this since anyway preferably all the screen display preferably goes through an intermediary layer which converts it to vector graphics in order to enable the resolution independent user interface, as explained elsewhere in this application. Another possible variation is that in this case at least when the problematic application is minimized to a mere square on the taskbar and/or when it is paused then preferably the graphics is automatically switched back to the enhanced mode (AERO in case of Vista), and/or at least, even when the application is running in partial window or full window, at least the taskbar preferably remains with the same color as in the enhanced more and/or at least the animation effects of growing or shrinking windows and/or the Flip 3d are preferably still working, even if somewhat slower. Another problem in Windows Vista is that when showing the size of the disks for example in “My computer” (Renamed in Vista to “Computer”), the OS shows each partition or disk as horizontal bars of the same lengths, and within each such bar the empty part is marked in a different color than the full part, thus giving a visual image of how much free space remains on each disk, so if various disks or partitions have significantly different sizes this can be very confusing since for example a 30% free space on a 80 GB partition is much larger than a 50% free space on a 30 GB partition. So preferably this is improved so that the bars are at different sizes according to the actual size of the disk or partition, preferably in proportions that correspond to the actual size at a preferably constant ratio, so that the visual representation preferably gives the correct relationships. Another problem for example in Windows Vista (at least in the betas and in RC1 &amp; RC2) is that the OS supports automatically reading CDs that were saved with Direct CD (for example DirectCD version 5.31 or 5.34), but if the user tries to write on them, the OS seems to write on them but actually screws them up. In addition, Vista does not allow the user to install DirectCD. So preferably this is improved so that the OS natively supports direct drive access to CDs or DVDs (preferably at least in the main 3 existing formats—DirectCD, InCD, and DLA) and preferably the OS also identifies the version in each of these formats and if there are differences in the internal version preferably can write in a way that is compatible with it, and if for example the OS does not support correctly writing to one or more of these formats or one or more version within such a format, then preferably the OS returns an error message that writing to this CD or DCD is not supported, but does not write in a way that can damage the format. Another problem for example when burning CDs or DVDs for example with Nero on Windows XP is that if one or more of the files which are supposed to be burned is erased by mistake before it was burned (for example if the user copied files into some temporary directory for burning and then erases them too soon), Nero issues a warning message, but only as a log at the end, and actually burns the file as an empty file containing zeros. So preferably this is improved so that if such an error happens preferably the burning software temporarily halts the burning process and informs the user about the problem and preferably gives the user a chance to copy again the missing file or files before proceeding. Another possible variation is that when using for example a program, like NCD (Norton CD), preferably the user can also activate a fast-update command which scans and updates only the directory structure of the current directory and its subdirectories instead of running over the entire partition. Another possible variation is that for example until the Vanderpool and/or the similar AMD Pacifica or other similar technologies become available, preferably the user can for example switch between two or more operating systems by jumping between hibernate states instead of having to boot from scratch. For this preferably the system allows the user after entering hibernate for example to press some control which shows a menu of the available current bootable OS options, and preferably shows also if any of them can be entered through resume from hibernate or a real boot is needed (because the user did not leave that OS on hibernate the last time he/she exited from it), and then preferably clicking on the desired choice lets the user resume from hibernate in the chosen OS if such a state currently exits. Another possible variation (for example especially if there is for example sufficient free RAM or for example flash memory) is that the user can switch even faster to the other OS for example by clicking on some control or menu item while still working in the current OS and thus entering the menu, and in this case if the user clicks on restore from hibernate on the Other OS then preferably the resume from hibernate in the newly entered OS can occur even before the current OS image is saved for hibernate or during the same time (and this can be even faster if the hibernate image of the newly entered OS is for example still available at least partially also in RAM. (However, in order to enable this at least some process preferably runs below both OS&#39;s and takes care of finishing the saving of the image of the OS which the user just left while the user in entering the new chosen OSS. Another problem is that for example (according to a channel 9 video by Microsoft from Oct. 6, 2006), in Vista after standby mode or after hibernate the OS does not rely on external memory sticks because it is not sure if it was replaced during the standby or hibernate mode. So preferably this is improved so that the preferably the hardware itself (for example some firmware and minimal processor for example in the connector) preferably keeps running and preferably for example updates in a log if the memory stick is removed. Another possible variation is that preferably the OS or the hardware for example automatically assign for example to one or more special cells in the memory stick—preferably each time when the memory stick is being inserted into the connector—a certain value which can be for example a large random number, and preferably for example if the OS is awake then a copy of this value is also entered for example into some local buffer, and so preferably after waking from hibernate or from standby preferably the OS or the firmware automatically check if the two values still match, and if they do then the OS can know that the chance that the memory stick was replaced during standby or hibernate is very small, and/or for example the firmware in the connector automatically increments some counter each time the stick is inserts, and so when the OS is awake it after standby or hibernate it can check if the counter has changed. Another possible variation is to add to the computer various sensors that can automatically monitor the condition of the user, for example by various biometrics, such as for example sensing the user&#39;s heartbeat and/or respiration (for example by a special remote microphone), skin temperature (for example through sensors in the keyboard and/or mouse) etc., so that for example if the system senses a serious problem preferably the OS or a special application can for example warn the user and/or for example call directly one or more emergency numbers and request assistance for the user, for example through synthesized speech or SMS or for example use Instant Messaging. Another possible variation is that this sensing is not limited to when the user is sitting near the computer, so that for example there are various additional sensors for example in the room or in the house or for example some sensors which are worn by the user (for example if the user is at known risk) and preferably connect automatically to the computer for example by UWB or Bluetooth or other short range wireless connection. Similar systems can be very useful for example with various special sensors for example in trains or in cars, since for example if the train&#39;s driver has a heart attack and does not press the breaks before collapsing it can cause a dangerous accident. So preferably the driver&#39;s cabinet contains various biometric sensors which can work for example as described above, and/or for example additional sensors such as for example sensors in the seat or on various elements which the driver is supposed to interact with, and preferably the train&#39;s computer has also sensors (such as for example radar and/or ultrasound and/or video cameras) which can sense for example if the train is moving too fast toward a too near obstacle and then for example can preferably apply the brakes automatically and/or sound a warning. Although there are for example some trains which contain a ‘dead man switch’ which means that for example every 30-60 seconds the system indicates a sound and/or light and the driver has to press some switch to show that he/she is still alive and if he fails to press it a stronger warning is indicated and if he still fails to press it the train automatically stops, an automatic sensing system as described above is better since it can be much more convenient to the driver and it can preferably sense problems immediately without having to wait for the next activation. Another possible variation is that the system includes for example also one or more video cameras that constantly monitor the driver&#39;s cart and for example the computer&#39;s system can automatically analyze for example un-normal positions of the driver and/or for example the image is broadcast automatically for example every few seconds to various ground stations. Similar sensors can be used for example in cars, so that for example if the computerized system senses that something is wrong with the driver (for example the driver has fallen asleep or is not feeling well, which in the case of a car can also be based for example on sensing erratic behavior of controlling the car—for example erratic movements which seem to ignore the track) it can for example try to alert the driver by sound and/or for example jolting or rocking the driver&#39;s seat, and/or for example can apply an automatic system which can preferably sense the contours of the road and/or the white lines and/or the position on the road and/or the surrounding vehicles and/or other objects and can preferably automatically slow down and move the car sideways and come to a safe automatic stop on the margins of the road and/or for example issue an automatic call to emergency services. In addition, for example in cars that have various sensors against collisions (for example radar, visual, ultrasound, etc.), preferably the car has also sensors between the front and back wheels, so that the car can also preferably instantly warn the driver and/or automatically take over for example in case an object, for example a kid, gets between the two sets of wheels. Another possible variation is that for example the car&#39;s sensors of impending collisions can be left active at least partially (preferably with low energy consumption) even for example when the car is parking (for example by activating some radar and/or other signals and/or sensors for example every second or other convenient interval at least for short range), so that if the car senses for example an impending collision preferably it can for example automatically broadcast a warning for example by automatically sounding the horn and/or for example by automatically flashing lights (and/or for example automatic wireless communication). Another possible variation is that is such cases the car can also automatically activate for example one or more video and/or still cameras and thus can for example keep photos for example if another car hits the parking car, so that the hitting car can preferably later be identified with proof. 
         [0120]    Another possible variation is to add for example preferably automatic preferably smart temperature and/or light permeability control to cars, for example while they are parking and/or while people are in the car, preferably by computerized control. Preferably for example during parking preferably the car&#39;s computer system (and/or for example an additional preferably computerized system, which can for example be installed as an add-on in existing cars) preferably uses automatic heat and/or light sensors to decide what to do and preferably uses low energy methods and/or for example operates when the user is about to enter the car and/or also when people are in the car. This can be done for example in at least one of the following variations:
       1. Preferably the car uses smart windows which can be automatically adjusted for example for heat permeability and/or light permeability for example mechanically and/or electronically (for example by their own nature and/or by command). The idea of using smart windows also in cars is not new, but what is missing is automatic smart control. Preferably electronically controlled smart windows are used, such as for example the already existing Suspended Particle Device (SPD) windows, which are comprised of two panes of glass sandwiched around a special film containing a liquid suspension, as described for example in http://64.233.183.104/custom?g=cache:IB0A6tTIBUUJ: www.sun-sentinel.com/technology/chi-windows,0,2,384687.story+%22Scientists+see+improved+windows %22&amp;hl=en&amp;ie=UTF-8. In the liquid suspension are microscopic light-absorbing particles that are randomly scattered to block the passage of light for making the window dark. When an electric charge is applied the particles line up in tight rows, allowing light to pass through for making the window transparent. SPDs also allow a range of transparency, permitting for darker or lighter window tints depending on the amount of voltage applied. Research Frontiers Inc., (RFI) of Woodbury, N.Y., holds over 360 patents relative to SPD technology and is actively licensing the technology to film and glass manufacturers worldwide. Unlike other smart window technologies it&#39;s durable, cheap and relatively easy to make and apply, and it is expected to cost around $15 to $30 per square foot, compared for example to $80 to $150 per square foot for electrochromics or LCD windows. This is also much better than LCD windows, since LCD windows typically enable only a dark and a bright state without in-between states. SPD windows are capable of going from completely dark to clear almost instantaneously. In darkened mode, the glass appears a very dark blue (Chicago Bears blue) with lighter tint levels having a slightly blue cast. However, a 100-square-foot window uses about the same amount of electricity as a 60-watt light bulb, which means that preferably the car is able to apply smart energy considerations as explained below. Another possible variation is to use for example the smart windows described in http://www.nature.com/news/2004/040809/pf/040809-2_pf.html, published online on Aug. 10, 2004. According to this article, a team of researchers has created a window coating that reflects the Sun&#39;s heat without filtering out visible light. At lower temperatures the new coating allows through both visible and infrared rays, just like normal glass, but once it heats up above 29° C., its atomic structure changes and it begins to reflect heat. It was invented by chemist Troy Manning together with Ivan Parkin at University College London and is made from vanadium dioxide mixed with 1.9% tungsten metal, and apparently they have been able to change the mixture to reach also lowers threshold temperatures, even a slow as 5° C., which means that various glasses can be prepared according to the desired threshold. However, such a window is problematic for computerized control since it does not respond automatically to computerized control, so preferably such a windows is used in combination with a window than can change on command, such as for example the SPD windows, so that for example the glass contains for example both the coating needed for the Automatic changing by temperature, and an inner layer of the material needed for SPD. Another problem is that since car windows are usually specific for each car model, thus creating problems for mass production, and since the solution is preferably made available also for existing car owners, preferably the vanadium dioxide mixture (and/or for example other mixtures with similar properties) can also be marketed for example as a spray or other means which the user can use to coat exiting windows and/or for example similar spray or other coating means which can be sold to car manufacturers for easy addition to their production lines. Similarly, the SPD windows could have an even bigger problem in creating two layers for car windows, since that might mean having to create for example two layers of half-thickness for each type of window glass for each model in order to add the SPD layer in between. Therefore a better solution is that preferably for example instead of two glass layers only one layer of glass is used, and preferably the SPD layer is coated for example on the inside or outside of the glass (but more preferably inside), and preferably an additional transparent coating is added over the SPD, preferably to insulate and protect it. This additional layer can be for example based on some transparent nylon or plastic, which is also preferably electrically insulating, since electricity needs to be run through the SPD layer. The means for adding these two layers (the SPD layer and the additional cover layer) can also be sold for example to car manufacturers for preferably easy integration with their production lines, for example in the form of a spray, and/or for example sold also to existing users, preferably as a kit, preferably with some means for ensuring that the layers have been coated in a sufficiently thick and regular way, and/or sold at least to garages or other professional services which can preferably easily add these coatings to existing car windows. Another possible variation is that for example the vanadium dioxide mixture layer (and/or for example other mixtures with similar properties) is preferably also covered with an additional transparent protection layer for example to protect it from peeling off or being scratched. An article in Israeli news paper Maariv from Aug. 25, 2005 suggests using in cars windows that change light by changing polarization but does not show any enabling way to do it. This would be problematic since car windows are rectangular and the short article in Maariv does not refer to this problem or show how to do it in practice. So preferably if such a solution is used, preferably it is done by adding for example between two layers of glass (in which preferably only one of them is preferably polarized) a third preferably circle shaped polarized layer which can preferably be rotated preferably by electronic command between the two external layers, thus preventing the user from being physically disturbed by the rotation. However, this means that only part of the window can be darkened this way. Another possible variation is for example to use more than one such circle in the inner layer, so that better covering is available (for example 2-10 or any other convenient number), and/or using for example more than one layer, so that there are preferably much less holes between the circles, for example by partial overlap between circles and/or for example enabling partial overlap between the circles within the same inner space, so that for example two or more preferably thin inner circles can be rotating partially on top of each other. This material can be for example based on preferably thin plastic compared to the car&#39;s glass, such as for example the material from which polarized add-ons for sun glasses are made (for example 1 mm or less in thickness). The control of the rotation of these circles can be for example based on small electric engines. (Of course a circular shape is just an example and other shapes can also be used, such as for example elliptical shapes or for example multi-rib shapes). However this solution seems more crude and probably less efficient than for example SPD glass or similar solutions. Another possible variation is to use for example one or more inner layers which can be for example moved up or down independently of the Window itself (but preferably not higher than the window), so that for example 1-4 or more inner layers coated with different combinations of vanadium dioxide can be preferably automatically moved up or down, each suited for a different threshold. Similarly another possible variation is that for example an inner layer with the SPD material can be for example automatically lowered up or down so that for example for keeping the windows clear during parking (for example in the winter), the car preferably simply lowers them, thus reducing any energy requirements to 0. On the other hand, for example in the summer the car might for example most of the time decide on maximum darkness, which means simply automatically turning off the energy to the SPD layer during parking. However, if for example the car decides on an intermediate state, preferably it can be made for example by either pulling the SPD layer partially in or out of position, and/or activating the SPD control for a certain intermediate level of dimming. Another possible variation is to simply use for example a light opaque layer of cheap material or materials (for example thin layer of plastic) which the car can automatically move up or down during parking, so that for example during parking if the car and/or the user decides on heat reduction, this layer is preferably automatically moved up. In this case this layer can be for example on the inner side of the windows without being between two glasses, since it would be normally used only when parking, thus not disturbing the passengers or driver when they are in the car. Another possible variation is that such a layer might be moved also from other directions but moving a thin layer automatically up and down for example from the same inner space in the door when the window is, is of course much easier and requires little change in car design. Of course, for example while parking, the car might decide automatically to what height to pull this layer up or down, thus for example reaching any range of desired heat penetration in-between states. Another possible variation, for example if 2 or more glass layers are already used, is to use for example a combination with a low-e type of glass such as for example the type described in http://www.energydepot.com/aglc/library/newpages/effwindo.asp, which can reflect for example between 70%-75% of the heat that would normally go to the outdoors, back in, during winter. However, in the Summer, according to that article, “low-E glass reflects about 25% more heat back outside than a single-paned window and 11% more than a standard double-paned window. The U-value for a double-paned window with Low-E glass starts at about 0.4. If a Low-E film is suspended between the glass panes then U-values approach 0.333 and even more of the harmful ultraviolet rays are blocked. A newer type of Low-E glass, often referred to as ‘southern’ Low-E glass, is designed to be most effective during the summer, by reflecting much of the sun&#39;s heat away from the inside of the home. Very often Low-E glass is combined with gas filling for U-values as low as 0.15”.   2. In some types of smart windows energy is required to keep the window dark and in some energy is needed to keep the window open to light, however since either way the car might need to choose levels different from the lowest energy state, preferably the computerized system also senses automatically the power level of the car&#39;s battery and preferably if the remaining energy goes down beyond a certain level then preferably the system can automatically for example reduce the operation of the automatic heat control and/or for example stop it and/or for example automatically start the engine preferably for a short time to charge the battery. Of course this could create dangerous air pollution if done in a closed space, but since the car preferably uses automatic sensors there is usually no problem since the car would normally have no reason to activate these means anyway in a closed space, such as for example in a garage on in an underground parking place, unless for example pre-heating is used automatically. Preferably the car senses automatically according to the temperature and/or light level and/or other measurements what is most desirable. For example in a cold winter day preferably the car automatically brightens the car windows while parking, preferably till the desired temperature is reached, and for example on a hot summer day preferably the car automatically darkens the windows while parking. (However, for example on a snow day darkening the windows might for example be an advantage because darker windows become hotter in the Sun and thus can for example better melt for example ice or snow that might otherwise accumulate on the window, however on the other hand if the snow has already accumulated then melting a the snow will create more ice). Or for example on a mildly cold day if the car is in a shaded parking place then preferably the car might automatically brighten the windows or for example leave or change them into an intermediate state and/or for example if the car is in the Sun then automatically the windows are made darker. Although for example a heat sensor within the car might be sufficient for example for deciding if to make the windows brighter or lighter, using for example also a light sensor can be important and can improve the decision making of the car, and also it can help for example for determining if the car is in a closed underground place or closed garage indoors, which means that for example the car must know automatically not to activate the engine for recharging the battery, since that could create dangerous air pollution. However, with a light sensor alone there is a problem of determining for example if a darkness is due to being in a closed place or due to night time, so the car preferably uses also a real-time digital clock which takes into account also the time in the day. In addition, preferably the car uses more than one temperature sensor, since for example the temperature inside the car might be considerably higher than the outside temperature, so preferably the car has at least one sensor in the car and at least one outside, in order to be able to make also smarter predictions based on outside temperature and not only depending on the internal temperature sensing. Another possible variation is that for example the car automatically adjusts the light permeability of the windows and/or the heat permeability of the windows when people are in the car, for example according to the operation of the air conditioner, so that for example if the air conditioner is set to cool, the car preferably automatically also reduces the heat permeability and/or light permeability of the windows and if it is set to heat then preferably vice versa (However when people are in the car of course preferably the light permeability is not reduced below a level that would cause visibility problems). Preferably the windows are capable of changing in more than one dimension, so that for example the heat and light permeabilities can preferably be controlled at least somewhat independently, so that for example the car can change the windows independently for visibility and for heat considerations.   3. Preferably the car can automatically activate for example the fan when the heat exceeds a certain temperature, so that preferably fresh air is automatically circulated through the car and the warm air gets thrown out of the car. Typically a car fan without activating the air conditioner can for example consume approximately 40 watts, which is much less then if for example the air conditioner is activated, and could run for example for 12 hours or more before draining the car&#39;s battery. However this is of course much less efficient unless combined with much smarter methods, which preferably enable the activation of this only when the user is about to return to the car or for example this is automatically stopped if the battery goes below a certain level, as explained above, and/or the car&#39;s engine can be for example automatically started preferably for a short time for recharging the battery and then stopped automatically, as explained above. These solutions are preferably applied also for example to SPD windows or other solutions that consume energy unless they are is the state that requires no energy, since if the glasses of the car windows for example altogether have a size of about 3.15 square meters (which is about 33 square feet), about 20 watts of electricity is required for example for keeping them clear. However, as explained above being able for example to also automatically move the SPD layer in or out of position for example while parking is better. Another possible variation is that for example at least one additional fan, preferably with at least one additional tunnel that can allow air in or out of the car, can be used, in order to improve the circulation of the air. This additional fan can be for example on the back side of the car, so that for example preferably both fans can work at the same time, preferably one for pushing fresh air into the car and one for pulling air out of the car.   4. When the user leaves the car preferably he/she can set a timer which tells the car approximately when he/she is about to return. This can be for example by rotating a mechanical timer button or for example pressing or rotating a button which controls a digital display, and/or for example the car can ask the user automatically, for example by voice communication when he leaves the car when approximately he/she is about to return, etc., and then for example he she can set the timer manually and/or for example also by voice command, which the car preferably acknowledges to make sure it got it correctly.   5. Another possible variation is that the user can for example use a remote car control which can preferably send a message to the car for example from a distance of preferably up to a few hundred meters or more (or any other convenient distance) to automatically prepare the car for entry, for example by reaching a pre-defined temperature (which can mean for example heating in the winter and cooling in the summer, etc.). This can be done for example by a radio signal from the remote control and/or for example by cell phone communication, etc.   6. Another possible variation is to use similar methods for example for automatically dimming the light when the sun is disturbing the driver, so that for example light sensors preferably automatically make the appropriate window or part of it darker if the car senses that the sun is blinding the user directly, and/or for example doing this automatically also for passenger windows. Another possible variation is that for better efficiency preferably this is combined also with sensing for example the position of the driver and/or the passenger and/or for example being able to darken or brighten one or more smaller specific areas in the window (For example by using SPD windows or LCD windows with smaller controllable areas that can change independently), so that for example the car can automatically darken for example only a smaller square near the point where the sun is seen and for example leave the rest of the window brighter.   7. In addition, preferably if the car can for example sense, for example by motion detectors and/or weight detectors and/or other detectors that for example a child or animal has been left in a closed parked car, it can for example start making sound and/or visual warnings and/or for example can automatically activate cooling controls for example more vigorously, such as for example also the air conditioner itself at least once in a while when needed and/or for example automatically opening one or more window at least partially, etc., and/or for example sending an automatic cellular phone message to the driver, etc. However, preferably the car can of course differentiate between a situation in which for example a child or animal was left by mistake in the car and a situation in which users are normally sitting within the parked car—for example by assuming that if the key is still in the ignition keyhole then the users are in control of the car, and, as implied above, manual override is preferably possible at all the states. So preferably if for example the key is in the ignition keyhole and there are people in the car while the gear is in parking then preferably nothing is done and/or for example only automatic heat permeability controls are used without automatically making the windows darker (and/or for example the user can allow the car to that also automatically for example even when there are people in the car together with the key). For example when the car is in parking without people inside then preferably both automatic heat permeability and/or automatic windows darkening is used if needed (for example according to the actual temperature and/or light conditions and/or time of day), preferably by default, preferably unless for example the users for example change some switch which overrides partially or in whole such automatic controls for example in general or for times of parking.       
 
         [0128]    Of course, various combinations of the above solutions can also be used. Another possible variation is that for example when the gear control lever is in Parking state the car can preferably automatically activate also the handbrakes (for example every time or for example only if the car is for example in a steep slope, which can be sensed for example by an automatic horizontal balance sensor) and preferably when the gear control is removed out of parking state preferably the car can automatically also release the handbrakes. However, if for example the car is on a steep slope, automatically releasing the handbrakes at the wrong time might be dangerous, so preferably in such cases it is released automatically for example only after the gear is for example in Drive or in Reverse and the driver presses the gas lever, and/or for example at least in some cases a warning is automatically issued to the driver to release it instead of automatically releasing it. And of course if such automatic activation and/or release of the handbrakes is possible, preferably the deriver can also cancel this automatic mode, for example by changing some switch. 
         [0129]    Another problem which cars is that for example the upper part of the engine is oiled automatically only when the user starts the engine, which is too late and causes the engine to be gradually damaged each time for about 1-2 second when the engine is being started, since it takes about 2 second for the oiling to reach the engine. Fiat solved this by activating the oiling when the user starts turning the key, however this still is not reliable since many times the user turns the key too fast and thus still starts the ignition before sufficient oil reaches the engine (in addition they added a mechanism for taking care of the excess oil while the engine is still not running). Therefore a better solution is to preferably use earlier sensing, such for example start oiling when the driver opens the door and enters or for example when he/she sits in his/her seat (for example by weight sensors and/or electromagnetic sensors and/or movement sensors) or for example when his/her hand moves toward the ignition keyhole (for example by infrared short range sensor, or any other relevant sensor). This is more preferable than sensing for example sitting, since it might take sometimes even a few minutes or more, or he/she might even for example prefer to remain parking for some time. On the other hand, after the driver inserts the key he/she usually starts the engine almost immediately, however he/she might for example just rotate the key partially for the electricity and stay parked for a while. So most preferably the sensor is based on the driver nearing his hand to the key (preferably for example by infrared sensor as explained above), since that is the most reliable predictor, since the driver won&#39;t normally hold his/her hand there unless he/she indeed wants to start the engine. Another possible variation is that preferably the system can also automatically stop the oiling—for example if the sensor is activated but more than a certain time passes and the engine has not been started yet (for example 30 or 60 seconds or any other convenient time). However, preferably this deactivation is not used if the user&#39;s hand itself is sensed near the ignition keyhole, since when there the chance is very large that the user will start the engine any second. Another possible variation is for example when an RFID immobilizer is installed, or with any other RFID for example on the key and/or keyholder and/or remote control, sensing automatically when the user&#39;s key is close enough to the ignition keyhole, however, as explained above that is less reliable than sensing the user&#39;s hand at that position. However redesigning the engine for enabling the circulation of the extra oil even when the engine is not yet running might be expensive. Therefore another possible variation is for example to add one or more preferably small oil containers preferably above the engine, which are preferably automatically full all the time or at least when parking, and when the user starts the engine preferably the top container or containers are automatically opened preferably instantly and pour their oil on the engine until the oil from the normal pump reaches the engine. Another problem is the inefficiency and waste of gas and air pollution when the car stops or moves very slowly for example in red lights or in traffic jams. This has been solved in hybrid cars (in which the car has an additional electric engine with special batteries for it) or mild hybrid cars (which use the alternator and the normal car battery for a short electrical push when the car begins to move after a stop) by automatically switching to electric engine when the car stops or moves below a certain speed. So in these cases preferably the system oils the engine automatically a short time before switching to the combustion engine. Another possible variation is that instead of or in addition to hybrid or mild hybrid solutions, preferably when the car stops and/or when it starts moving sufficiently slowly preferably the engine can automatically go down to a very low speed in which very low energy is used and preferably exhaust levels are very low, but preferably this speed is sufficient to enable the car to preferably instantly or almost instantly go back to normal speed when needed. Another possible variation is that preferably the car (preferably with the aid of its computer) can measure automatically for example the level of brakes fluid and/or the wear-out condition of the breaks. Preferably the car can sense if the brakes have worn out for example by measuring automatically for example the amount of pressure that needs to be exerted when braking, preferably while taking into account also the speed and preferably also for example the inclination of the road (for example up or down, for example by using a level measure). Preferably the car can sense for example if brake fluid is missing before the user needs to press the brakes, for example by adding a spring which keeps the clippers away from the brake&#39;s disc, so that preferably a small amount of pressure can be applied automatically to the brakes fluid for example all the time or once in a while, and so the pressure needed for example for creating a small displacement in the spring can be measured, or for example even without the spring a small displacement of the clippers can be created automatically for example without actually letting the clippers touch the discs, and thus the pressure needed for that displacement can be measured, or for example by an mechanical or optical sensor which can measure the thickness of the disc or of the clippers. Another preferably improvement is that for example in cars that work on hydrogen preferably the water vapor from the exhaust can be used for additional energy boost preferably through steam—in a way that is more efficient than adding steam to a normal car. Preferably this is done by mixing the exhaust water vapor with water preferably by streaming it back into a container with the water, and thus converting the high temperature lower pressure vapor into a lower temperature higher pressure steam, which can preferably be used for example for rotating a turbine, thus giving additional boost to the car. This is much more efficient than using a heat exchange for creating steam for example in cars that don&#39;t run on Oxygen. Another possible variation is that preferably cars are improved so that when the user changes the gear (preferably for example both in cars with manual gear and cars with automatic gear) preferably the car speaks automatically and tells the user the current position (such as for example ‘parking’, ‘Reverse’, ‘Neural’, ‘Drive’, ‘1’, ‘2’), so that the user can be sure of the position without having to look at the gear. Preferably this is done for example by playing back pre-recorded sound samples or by synthesized speech, which is for example added to the gear&#39;s computer or to some other computer which is informed by the gear about its current position. Another possible variation is that similarly for example refrigerators are preferably improved so that for example if their door remains open or not well closed for example for more than 30 seconds or more or 1 minute or more (or any other convenient time period), preferably the refrigerator automatically calls the user&#39;s attention preferably by auditory warning, such as for example beeping or playing for example a pre-recorded word or words (preferably by using a small processor and/or a sound chip which is preferably connected to the sensor that checks if the door is closed (typically a button that is pressed when the door is closed). Another possible variation is that preferably in electric cars the car can be quickly recharged in service stations (the equivalent of gas stations in normal cars) preferably by designing the batteries in a modular fashion so that preferably one or more of the batteries can be preferably instantly removed and replaced with charged batteries, and preferably the batteries in the car are configured so that they can automatically recharge each other or spread the power among them, so that for example if 12 batteries were replaces and 6 not then the 12 charged batteries can automatically share their charge with the other batteries that have not been replaced. The replaces batteries are then preferably recharged automatically at the service station, and preferably the service is based on some monthly subscription and/or some other identification of the customers, so that for example the user is extra-charged if his/her batteries are faulty, and/or for example the service includes also an extra charge for insuring the batteries. Another possible variation is that, since not everyone has a private garage when he/she can set-up an outlet for recharging an electric car, preferably for example the municipal authorities are responsible for creating preferably near street light poles and/or near power line poles also electric car recharging outlets, so that preferably the same electric wiring that already exists for the power line poles or the street light poles can be used also for the car recharging outlet preferably without having to add wires, and preferably the users pay for this by a credit card or smart card which is preferably read automatically by the outlet. 
         [0130]    Another problem is creating smarter preferably computerized vehicles which can preferably use virtual tracks and thus can for example replace LRT (Light Rail Transit). There is for example a new smart 2-part or 3-part articulated bus called Phileas, which is now in experimental stage in Netherlands, which can follow a virtual track marked by a magnet every 4 meters, which identifies the magnets by sensors, and each set of wheels is steer-able, so that each part of the articulated bus can more easily maneuver into the desired position. This can save a lot on infrastructure, however since there are at most 3 parts per bus, in terms of cost per passenger, in high demand routes this can still be operationally more expensive than running a light train (after the rail already exists). The Phileas is intended to be a hybrid bus, thus saving on gas and pollution. Another smart computerized solution is the Civis bus, which is guided by a camera at the front of the vehicle, which follows special stripes at the center of the traffic lane, and this detection device works up to a distance of 30 meters. The driver can take over the control at any moment. The Civis (which is 18.5 m long) will operate in Clermont-Ferrand and Rouen in France, and in Las Vegas, USA. However, the Civis uses a lot of fuel due to its considerable weight (17 tons), and another disadvantage is that the guidance is less reliable if the detection is based on fewer than three guidance stripes. In Netherlands the authorities decided that the visual tracking system is not sufficiently reliable, due to rain, autumn leaves, snow, and the low angle of the sun, and that is why they decided to use instead the Phileas. Both of these buses are examples of BRT (Bus Rapid Transit) systems. A better solution would be preferably to enable more parts for the articulated bus and/or additional coaches, and/or preferably enable an even cheaper virtual rail, which will still be preferably reliable enough, and/or preferably enable greater flexibility in deviating from the track. This is preferably done by preferably giving each coach and/or articulated part the ability to preferably automatically follow and imitate the same steering movements of the driver in the first part. This can be done for example by computerized control and communications, so that preferably each coach and/or articulated part preferably knows, preferably exactly, the distance (preferably for example in terms of number of wheel rotations) between it and the previous part and/or between it and the first part, and preferably all the steering actions of the driver of the first part are preferably automatically transmitted also to the other parts (for example by digital communication), so that preferably each articulated part and/or coach can preferably automatically repeat the same steering actions at the same position in the road (for example by doing exactly the same as the driver after the correct number of wheel rotations has occurred). This can enable easily using more than 2-3 parts, such as for example even 4-10 or even more articulated parts or coaches. However, such a method alone would have the disadvantage that various deviations might accumulate after a while if there is no self-correcting direct feedback. Therefore, preferably this system is preferably combined with automatic ability to sense the correct position relative to the virtual track and/or automatically correct the accumulated deviation, preferably compared to the first part (i.e., preferably the deviation is corrected to be the same as the deviation of the 1 st  part from the virtual track, since the driver would normally know best the desired deviation, even though another possible variation is for example to correct the deviation compared for example to general guidelines regardless of the deviation of the first part, but that is less preferable since the driver might have for example deviated on purpose for various reasons, such as for example a temporary problem on the track). This is preferably done for example by visual sensors that can automatically sense the marked trail (for example by video cameras). This has the advantage that it is cheaper than the Phileas method (since the track has to be marked anyway also for humans to know the track of the virtual railway, and thus no additional magnets or other indications are needed), and secondly, this is now much more reliable and less vulnerable to problems even when the marks are for example temporarily partially covered for example by leaves or by snow, since the parts can follow the first part&#39;s driver&#39;s steering movements automatically and thus the visual tracking can be used for example to correct errors for example once in a while and can be much more robust for example in cases where the marks temporarily cannot be seen. Another advantage is that this way for example there can be more than one such bus line so that for example each line has a different route but for example at least some sections are shared by more than one line. This would be very difficult in a system that is based only on following a marked rail without being also automatically able to imitate the driver&#39;s steering, since the other parts would not know which of the routes to follow for example after the vehicle exits the section of the route which is shared by more than one line. Another possible variation is to use for example a different color (and/or other different visual indication or indications, such as for example different line widths and/or patterns and/or other visual means and/or other means) for each line so that preferably the sensors of each vehicle can preferably also be instructed to follow the correct marking. This is better than using for example the Phileas magnets every 4 meters, since these magnets would make it more difficult to mark different routes (unless for example each such magnets can also have a special pattern or fingerprint and for example more magnets are used at least in shared sections, which is preferably done anyway, for example also in order to prevent the system from becoming confused for example if other magnets or magnetic fields or electromagnetic fields are in the area). Preferably there are multiple sensors on each part and preferably the part&#39;s computer preferably takes into account the average deviation from the marked track so that if for example the track is temporarily not visible then preferably it keeps for example following just the steering actions preferably until it becomes visible again, and also it can preferably for example understand for example that according to the steering moves performed it couldn&#39;t have moved for example more than a certain distance from the track, for example in case part of the mark is covered and for example the sensor for example perceives by mistake another mark, for example on the other side of the road, and/or for example it can see that according to the current angle between it and the first part and/or the previous parts and/or the new angle that would be created by moving to that mark this cannot be the correct mark. Such a system is also much more flexible than a light train because if for example there is a problem in the installation pipes below the road (which is the reason why so much money is spent on moving the pipes sideways before putting the tracks so that they are not under the tracks), and/or for example in case of temporary road blocks, under-road piping repairs, or other problems, preferably the driver can for example easily deviate for example 1 or even more meters from the normal route. Preferably the system also transmits automatically to the other parts the current deviation between the first part to the virtual track, and thus preferably automatically preferably each part can adjust its deviation to the deviation that was broadcast by the first part, preferably when reaching the same position in which that deviation was relevant. Another possible variation is that the driver can even deviate completely from the marked track when desired (for example if there is a suspect object that needs diverting traffic away), and then preferably the driver can for example send the other parts (for example by pressing a button or moving a lever) an automatic command to temporarily ignore the marked virtual track altogether and just follow the steering movements of the first part and/or at least temporarily use other means for correcting accumulated deviations. Of course various combination of the above and other variations can also be used. 
         [0131]    Another possible variation is that for example in straight sections the driver can for example issue a command to the other parts to align themselves automatically so that they become preferably exactly straight after the first part and/or for example each part after the previous part, and/or for example the parts can decide do this automatically for example when the first part transmits that the steering position of the driver&#39;s wheels for example are exactly balanced, thus indicating a straight line. For the creating the actual alignment preferably the parts can for example use visual means such as for example video cameras and/or other sensors in order to measure for example the difference in the distances between each part to the previous part on the right side compared to the left side, and/or for example the hinge or hinges between each two parts can automatically measure and report the angle in which it is currently in. For making the actual correction preferably the parts use of course the ability to steer preferably each wheel or each pair of wheels independently. This is another way of getting rid of the accumulated deviations. This way the need for marking the virtual track or depending on it can be even further reduced. Another possible variation is that for example even without a visually marked track the first part can for example broadcast to the other parts at least once in a while (for example every 30 seconds or for example a few minutes or any other convenient interval, or for example when the first part senses conspicuous elements in the contour which can be used as good reference points) various automatic measurements of its position relative to the road or to the surroundings or to said conspicuous elements, for example by radar and/or the visual imagery and/or other sensors, and thus for example the computerized system on each part can for example compare the data it received from the first part with its own measurements when it reaches the same spot and thus automatically calculate the amount of the current deviation. Like in the adjustment according to the marked virtual track, in this case also preferably the system automatically takes into account for example the reasonable possible deviation for example according to the recent steering maneuvers performed and/or according to the current angles, so that preferably it will not make a correction for example if the projected correction means significant deviation from the current angle and/or position. Of course various combination of the above and other variations can also be used. 
         [0132]    Of course, if for example 1 or 2 electrical wires are used on top of the route for supplying electrical power to the smart bus, then preferably this can be used is addition to or instead of the visual tracking, and this means that preferably each part has at least one or more arms which connect to the top electrical wire or wires, and preferably these arms are flexible and extendable, for example by being able to change their angle and/or preferably automatically become shorter or longer as needed (for example like a foldable antenna, for example of the type that uses movable tubes within each other or for example like multiple connected X&#39;s which can become shorter or longer by changing the angle of each X), so that preferably they can work OK for example even if the part deviates for example even 1 or a few meters (or less or more) from the normal route, and preferably each such arm also automatically senses the distance between the part and the electrical wire. Another possible variation is to add for example to each part also automatic impending collision detectors (for example visual and/or by radar and/or laser and/or any other known means) for example sideways and/or also forwards and/or backwards, so that preferably, for example even when the part automatically adjusts its position, it preferably automatically avoids moving in a way that would cause it to collide into something. Preferably such sensors are also added for example between the wheels, so that preferably they can detect also for example if a child or an animal runs or is about to run between the wheels and can preferably automatically take evasive actions, such as for example maneuvering sideways to avoid the collision and/or for example causing automatic braking or at least slowing, etc. However, the visual sensing and automatic correction in combination which the automatic imitation of the steering actions of the driver is just an example, and this can be used for example also in combination with any other sensing methods, such as for example in combination with the Phileas, since the automatic imitation automatically makes it more reliable to use the feedback sensing, since preferably the sensing is needed just for correcting deviations at least once in a while, and preferably in all of these variations preferably the deviation of the first part from the route is preferably automatically sensed by the first part and preferably automatically conveyed by communication also to the other parts. Another possible variation is that for example in systems like the Phileas, even without steering motions imitation, preferably the first part can automatically for example instruct the other parts to repeat the same deviation of the 1 st  part, so that for example if the driver deviates for example even 1 or more meters from the normal tracks for example due to some problem, preferably the other parts can automatically try to reach the same deviation (for example at least in one of the possible operation modes), preferably at the same spot, preferably for example also by counting wheel turns. So for example at stations with special elevated platforms preferably the driver can for example instruct the other parts to alight themselves automatically with the exact markings (and/or for example there is a special signal at such stations with issues that command automatically to the parts, for example by wireless and/or special magnetic patterns and/or for example special optical marks), and for example during travel or in normal stations without elevated platforms preferably the parts are automatically in the mode that imitates the deviations of the first part (with or without imitating the steering movements of the driver of the first part). (Actually even for example in stations with elevated platforms the driver will typically move the first part as close as possible, so the other parts can do the same anyway, so preferably the other parts can be for example in imitation mode all the time). However even for example in a system like Phileas, adding for example also the ability to imitate steering motions means very little addition in costs (since it is mainly some additional communication and some additional computer control), and has the advantage of for example enabling the bus much more easily for example to temporarily deviate entirely from the marked route and/or for example enables much better control when for example more than one line share a common section, as explained above. 
         [0133]    Of course various combination of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0134]    Similarly, preferably the car alarm is improved so that if the car is being stolen, preferably the alarm system automatically broadcasts a distress signal (preferably secretly), preferably through a hidden cellular device, and preferably indicates the position of the car for example according to GPS and/or for example according to the nearest cell positions in the cellular system. Another possible variation is that for example the car&#39;s system can automatically broadcast for example to parents if their son or daughter drive carelessly (for example too fast, or with too sharp turns and/or other indicators of dangerous driving which can preferably be automatically measured by the car itself). Although there are systems today where other drivers are asked to report this to the parents, it is much more preferable that the car&#39;s computerized system can report it directly by itself, preferably through the same cellular system that can be used also by the automatic alarm for example if the car is being stolen. In airplanes for example a similar system can preferably also sense for example if the plane has been hijacked, for example by sensing that the biometrics of the pilot indicate a different pilot (for example by automatic fingerprint readers in at least some of the controls which the pilot has to touch and/or for example automatic iris readers in the pilot&#39;s helmet) and/or sensing that unauthorized persons are in the cockpit (for example by sensing one or more people standing or sitting in a suspicious position for example for more than a limited period) and then for example the system can automatically send a wireless warning to various ground stations (and preferably also for example automatically open one or more microphones and/or video cameras which automatically broadcast what is going on in the cockpit and/or for example the microphones and/or video cameras normally broadcast the situation automatically every once in a while to one or more ground stations even when no special event is detected) and/or for example to security persons on the plane itself and/or for example the system can ask the pilot (preferably by a hidden method of for example displaying some digits which have a special meaning or for example flushing them, etc.) for identifying himself with a special code which only the legitimate pilot would know, and so for example if a hijacker is sitting in the seat instead of the pilot he would not know the correct response or even that he was asked to respond and if the pilot is still in the seat and the hijacker is standing next to him the hijacker preferably would not be able to see the signal (for example by using viewing angles which only the sitting pilot can see) or would not understand it and then the pilot can for example ignore it or enter a special code instead of his/her normal code that indicates that the plane has been hijacked and/or can convey other messages) and/or for example one or more controls in the cockpit can be used by the pilot to indicate various problems (which can preferably automatically activate for example automatic wireless warnings), for example by moving a lever into a special position which has no real mechanical function but is used in that position to activate automatic warnings, etc. In addition, in cockpits preferably the computerized system preferably has also means for automatically disabling hijackers, such as for example shooting tranquilizer arrows or needles (or for example electric shocker needles) at anyone who is standing at a certain height and/or who is standing next to the pilot for more than a certain time limit and/or who is standing at an unauthorized position (for example automatically or for example upon a hidden command from the pilot or for example upon hidden wireless command by ground control, preferably with high encryption that makes sure that only authorized commands will go through) and/or for example at the person in the pilot&#39;s seat (for example if the system has determined that the pilot is not legitimate) (and/or for example automatically electrically shocking the illegitimate person and the pilot&#39;s seat) and/or for example releasing a preferably odorless gas, preferably together with automatically activating an automatic pilot and/or for example activating a special mode which takes navigation commands from the secure wireless channel. In addition, preferably the cockpit is protected by a system of at least two preferably fortified preferably closed automatic doors, so that any person entering or leaving must first pass one door, then close it and then pass the other door. This is better than the prior art since in the prior art cockpits are either not protected by a fortified door or are protected by only a single fortified door, which is still not safe enough because a hijacker can for example run in when the door opens for the pilot to go to the toilet for example. If the passage near the cockpit is too small for adding normally the second fortified door then preferably one of the doors can be for example based on a rotating part-circle, or for example the two doors are connected with a foldable sleeve (for example like an accordion) which is pulled out only when someone has to pass through the two-door system. 
         [0135]    Another possible improvement is for example improving the software in cellular phone networks and/or in the cellular phone itself so that for example the phone can preferably indicate to the user differently for example in cases of bad reception if the bad reception is on the side of the user or on the side of the other person with whom he/she is trying to talk. This is better than the prior art, in which the phone indicates when there is bad reception but does not indicate if it is caused by the side of the user or by the side of the other person. This information can be for example supplied to the phone by the cellular network and/or the phone itself can deduce it automatically for example from the quality of its connection with the cell in comparison to the quality of the connection with the other phone. Another possible variation is that for example the cellular phone can automatically indicate to the user the current level of radiation it is using, for example by some visual indication and/or for example by some auditory indication, especially for example if the radiation becomes higher than a certain limit. Preferably the user himself/herself can manually set the threshold. Another possible variation is that for example when there is a bad reception and the user for example prefers to talk later when the reception improves, preferably the user can tell the phone for example to indicate to him/her automatically when the reception improves (which can be done for example by a special ring). In this case, preferably the indication can be for example different according to the source of the bad reception, so if the source was the user&#39;s own phone then preferably the phone simply indicates when the connection with the cell becomes better, and if it was the other phone then preferably the cellular system automatically informs the user&#39;s phone when the reception is better, preferably according to the information it receives from the cells near the other phone. Another possible variation is that for example VoIP phones or preferably dual phones which can make and receive both normal phone call and VoIP phone calls as explained also in other applications by the present inventor, preferably contain within themselves also for example a cable model or for example ADSL modem or other means of connecting directly to the Internet, so that it can be connected directly. 
         [0136]    Another possible variation is to create for example a smart computerized (wheeled) shopping cart for supermarkets, or for example a hand held gadget, for example for DVD libraries or book libraries in which for example items that can be bought or loaned preferably each has an RFID which can respond to queries from the gadget or from the shopping card, and so for example the user can type or speak the name of a desired item and the cart or gadget preferably shows for example on some small screen the list of items that fit the query, and if the user clicks on one of them preferably the cart or gadget can for example show its position according to its own database (which is preferably updated for example preferably at least daily for example by communication with the store&#39;s main computer) and/or can for example locate items, at least when they are not in the expected place, for example by sending RFID queries to them and using preferably more than one sensor in order to triangulate their position. 
         [0137]    Another possible variation is to create for example preferably computerized smarter water disposal systems in homes, so that for example if the user wants to user “grey water” (i.e. for example water from the shower) for example to water the garden, preferably the water goes through one or more sensors which can preferably (for example by visual and/or spectroscopic analysis and/or other preferably cheap and preferably instant on-the-fly means) find out for example if the water contains soap or is sufficiently clear, and thus can for example automatically toggle a valve which dispenses the water for example either to the sewer system or to the garden. This can be very useful since for example when people take a shower it is undesirable that the soap reach the garden (which might even create the danger of polluting deep underground water reserves), but for example perhaps in 90% or more of the shower time the soap has already been washed away so the water is relatively clear, and thus this clear water can preferably be safely identified and used this way. Preferably this system lets the water pass through a temporary buffer in order to create some delay for deciding about the clarity of the water, however this may be unnecessary since for example decision according to visual analysis can be more or less instantaneous. Of course this can also be used for example in combination with one or more filters. Another possible variation is to use for example a smart computerized toilet water stream controller which for example uses a still and/or video camera (such as for example a preferably cheap preferably wide-angle view web-cam) to view the toilet seat&#39;s internal walls and for example automatically directs the stream mainly towards the dirty area or areas (for example by controlling a rotate-able faucet head which sprays the water (another possible variation is for example, in addition or instead, to add for example a rotate-able manual control, for example to the button that activates the toilet washing stream, so that the button is for example at the end of a rotate-able handle and the user can for example rotate the handle to control the main direction of the stream. However, it is much more convenient to have it computer-controlled since this may enable better cleaning even for example with a smaller amount of water, thus saving also ecologically. 
         [0138]    Another possible variation is to create for example a smarter refrigerator which for example uses a computerized system and/or smart sensor or sensors which can for example warn the user automatically, preferably by auditory and/or visual cues, if it has been left open for example for more than a minute (or other reasonable time period, preferable changeable by the user) or for example is not closed well (for example by sensing a gap of more than a minimal threshold distance between the door and the side which the door has to attach to when closed (this sensor or sensors can be for example optical and/or mechanical and/or electromagnetic and/or for example based on induction. Another possible variation is that the refrigerator can also for example inform the user about this for example through a smart home network, for example directly to his/her computer, or for example send the user an automatic phone call or SMS, for example if the user is out of the house. Similar warnings can be attached also to other devices, such as for example detecting gas leakage if the user forgot the gas open. This is preferably done by gas flow detectors for example in the home gas supply (preferable for each of the turnable gas faucets, preferably together with heat and/or light detectors which can detect for example if a fire is burning on the open gas faucet or not and/or for example smell detectors which can detect the smell of gas. 
         [0139]    Another problem is that for example in laptops typically the hard disk is significantly slower than in non-mobile computers, in order to save power and extend the number of hours until the batteries run out of power, which causes many programs to load considerably more slowly and to work slower when saving or reading files. However this creates the absurd situation that even though the laptop might be used most of the time on a desk, connected to the wall electricity outlet, the disk still works at the low speed all the time. So this is preferably solved by using a variable-speed hard disk which can automatically work significantly faster when the laptop is connected to the network electricity. So preferably the computer and/or the OS and/or the disk itself can automatically increase or decrease the speed of the hard disk according to sensing if the computer is currently connected to the network electricity or is currently running on the batteries. In addition, preferably the user can also for example press some button or request the OS to increase temporarily the disk&#39;s speed to the fast mode even when not connected to the external electricity (for example if the user needs something done fast, and then preferably the disk for example automatically reverts back to the slow speed for example after 5 or 10 minutes or any other convenient time, and/or for example according to the amount of power left and/or the current processes running, such as for example until one or more specific tasks finish). Similarly, preferably when the portable computer is connected to the wall preferably the hardware and/or the OS can also for example automatically increase the speed of the CPU so that it consumes more power and works faster (and/or the user can for example request it explicitly for example at least for a short time even when the portable is not connected to the electrical outlet) and/or for example automatically (and/or by temporary user request) increase the brightness of the screen, and/or for example increase the speed and/or power consumption of other elements. In case the user requests the increase in disk speed and/or the other increases in power consumption explicitly while the computer is working on batteries, preferably the system resorts automatically to normal power consumption for example after a specific task is completed and/or for example after a certain time period (which can be for example set automatically or by the user). However, there is a problem that if the disk&#39;s engine is optimized to work efficiently when the power is on, it might work considerably inefficiently when running on the batteries, and if it optimized to run at high efficiency when running on the batteries it will not run efficiently when running for example in double speed when connected to the wall, thus increasing even further the heat dispersion problem in the laptop. In order to solve this, preferably the disk has at least two sets of engines or at least two sets of coils, which are used for example at different combinations in order to work efficiently in the low speed or in the fast speed (or other speeds if more than two speeds are available). In addition, preferably the disk&#39;s DSP automatically starts working for example at higher MHz when the wall power is sensed and/or for example more than one DSP can be used in order to speed up the processing. Another possible variation is using for example a disk with more heads on the same arm (which is typically moved in rotational movement part of a circle from the side, in a way similar to a phonograph&#39;s needle, typically by a voice coil), so that for example less movement is sufficient to cover the entire range. Although this means also having to move more mass, the arm is typically much more massive then its tip with the head, so adding one or more additional heads that point for example sideways, as shown in  FIG. 5   a  below, will not change much. Another possible variation is adding also for example additional heads, so that for example there are more heads at the length of the arm, however that could create a linearity problem. Other possible improvements that should enable faster disks with very little energy increase or even a reduction in energy consumption are shown in  FIG. 5   b - c . Another possible variation is to use for example instead of moving heads some elongated multi-head structure which does not have to move at all, so that preferably the point of reading is chosen electronically, for example by varying the position of some crossing point electronically. (Such a solution of course could make also normal hard disks work considerably faster). Another possible variation is to use even more than two speeds or modes. Another possible variation is that for example the user can choose in advance when buying the laptop if he/she prefers to get the laptop with a faster speed hard disk (for example a double-speed hard disk that will cause the battery power to run out for example after 2 hours), or a slow speed typical laptop hard disk which is for example twice slower but allows the battery with average usage to last for example for 3 hours). The heat dissipation problem with the faster disk is preferably solved for example by activating automatically for example an additional fan when the disk works at the higher speed, and/or adding for example additional heat conductors between the internals of the laptop to its outer shell. Of course, various combinations of the above and other variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0140]    Another problem is that in computer cases that have a dust filter, the user has no indication when the filter becomes clogged, except when the situation reaches the point that for example the CPU reaches a temperature that activates an alarm for example by the temperature monitor. So preferably this is improved so that for example a sensor (or sensors) on or near the filter can automatically sense how covered with dust the filter already is (for example by measuring electrical resistance and/or for example air flow and/or for example measuring the level of light that comes from a light source on the other side of the filet, and/or other parameters), and then can preferably automatically warn the user (for example by activating an application which displays for example a visual and/or auditory warning) when the filter is too clogged and needs cleaning—before the CPU becomes too hot. Another possible variation is that for example when the sensor indicates a certain level of blockage of the filter (and/or even for example on a regular basis even without the sensor) the system can preferably automatically clean the filter, for example by moving one or more brushes or arms or other moving elements (which can also be for example charged with static electricity) for example sideways and/or up and down and/or in other directions over the side on which the dust collects and for example pushing the dust for example to a cavity in the sides and/or in the bottom which can collect the dust so that it does not obstruct the air flow. In this case preferably there is an additional sensor (or sensors) which notifies the user when this additional cavity (or cavities) become too full and need to be emptied. Similarly, preferably there is such a brush and/or sensor also for example also coupled to the CPU&#39;s heat sink, since for example even good cooler solutions such as for example Arctic cooler still have the problem that various dirt particles tend to get struck between the fan and the hit sink and so divert part of the airflow away and can cause even a 10 degree Celsius increase in the CPU temperature. In this case preferably the brush or other cleaning moving element is preferably for example on a horizontal hinge that runs for example between fan and the heat sink so that for example normally the brush is rotated for example to the extreme right or left so that it does not obstruct the path of the air between the fan and the heat sink, but for example when rotated it can preferably move in its path preferably over most or all of the area of the air entrance to the hit sink and preferably has for example hairs that protrude into the cavities of the hit sink and can thus clean them for example by rotating on the hinge, and so this brush or other moving elements is for example preferably activated automatically for example based on the sensor and/or for example regularly—for example a few minutes a day or at other intervals and/or for example preferably during idle times preferably when the CPU utilization is minimal so that the brush itself preferably does not increase the heat while moving. Similar solutions can be used also for other devices that have air filters, such as for example clothes driers. Another possible variation is to use for example near or at the dust filter, for example in computers or in clothes driers, a centrifuge (for example like in the vacuum cleaners by James Dyson) so that the dust is automatically thrown to the sides and this dues not obstruct the passage of air even when it accumulates. 
         [0141]    Another issue that has to do with the reliability issue is the fact that when people use Windows for example from an Internet Café, many times they forget to close down open connections and/or at least they leave behind traces such as for example various cookie files, temporary files, history logs, etc. There have already been cases that users who subsequently used the same computer misused this for example to send a false suicide note or to send a false kidnapping message, etc. Although some web based email sites, such as for example Hotmail and Yahoo, allow the user to mark when he/she is using a public computer, this relies on the user marking it and is anyway just a limited solution. Therefore, preferably the OS itself, preferably during installation, enables the administrator to specify that this is a public-use computer, and preferably this setting can be changed only for example with the original installation disk and/or with a password. Preferably when defined as a public computer, the OS itself indicates this in outgoing electronic communications such as for example emails, for example by adding this info at the socket layer, and preferably any session-related traces are automatically removed by the system for example after a short time of inactivity and/or if the user does not re-enter a password chosen by the original person that started the session, or for example such traces are not saved at all. Another possible variation is that in addition, for example the OS allows the user to send additional email messages from the same session only if he know the password entered or chosen by the user when he/she started the session, etc.

       [0149]    All these drawings are just exemplary drawings. They should not be interpreted as literal positioning, shapes, angles, or sizes of the various elements. Throughout the patent whenever variations or various solutions or improvements are mentioned, it is also possible to use various combinations of these variations or of elements in them, and when combinations are used, it is also possible to use at least some elements in them separately or in other combinations. These variations are preferably in different embodiments. In other words: certain features of the invention, which are described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination. The above rules of course also mean for example that throughout the specification, including the claims, the words “all” or “each”, such as for example “each question” or for example “each level” or other word combinations that contain the word “each”, do not mean necessarily all the items but can mean simply individual items in general or some of them, i.e. it can be for example a general rule, but not necessarily without exceptions. Eventhough the preferred embodiments use mainly the terminology of Microsoft Windows, which is the most common and familiar operating system, the current invention can be used also in other operating systems, such as for example Linux, Macintosh, or other operating systems, even if they use different terminologies or different implementations of various features. “OS” as used throughout the patent, including the claims, means Operating System. FAT is short for File Allocation Table. However, as used throughout the patent, including the claims, FAT can mean also any other central data structure related to file allocation or management. “Scandisk” is the typical software used in Microsoft Windows to scan the disk. On normal runs it is used mainly to find inconsistencies between actual file sizes and the sizes reported in the FAT, but it can be used also for example for thorough scan to check for bad sectors, etc. As used throughout the patent, including the claims, “Scandisk” means either Scandisk, or any other similar software for checking the Integrity of the files or directory structures. “Image”, as used throughout the patent, including the claims, means a non-volatile memory Image of the OS state and preferably also loaded programs, loaded drivers, memory status, status of peripheral devices, and/or any other data that is needed for creating a sufficient snapshot of the computer&#39;s condition, so that the computer can be instantly restored to that state and operate properly by restoring or using the data from said Image. Throughout the patent, including the claims, whenever “disk” or “disks” is mentioned, it can be either a hard disk or hard disks, or any other type of fast access not-volatile memory, such as for example MRAM (Magnetic RAM), 3d Nano-memory chips, etc., and whenever heads are mentioned, it can be either read/write heads of disks, or any access mechanism for areas in other types of non-volatile memory, including when such access means do not require actual physical movement by a mechanical element. “Preview images” or “Preview windows” refer to small images of actual windows which are used to help the user choose the correct window for example from the task bar or from a group of tab handles (this can show for example simply a reduced image of the window and/or for example certain more important features of it which can help differentiate between it and the other windows or tabs, and may include for example even streaming data or movement, such as for example a reduced image of a playing video). Throughout the application, including the claims, whenever is says for example that the OS and/or for example the security system can do something, it can be done of course also for example by some other application and/or driver. Group icon refers to the square button on the typically bottom taskbar which represents a group of open windows of the same application (or otherwise defined category). Throughout the specification and the claims when it says that for example the OS or the security system does something it can be of course also some other application or service that offers the described functionality, as explained also in other places in the application. Similarly for example when it says for example that the browser preferably does something, this can be for example also a plug-in for the browser which does it. “Desktop search” or “indexed desktop search” or “instant desktop search”, unless stated otherwise, refers to the typically instant indexed desktop search, such a for example Google desktop search, or for example the Microsoft instant desktop search, or for example the similar functionality offered inherently in Windows Vista. 
       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0150]    All of descriptions in this and other sections are intended to be illustrative examples and not limiting. 
         [0151]    Referring to  FIG. 1 , I show a flow chart of a preferable way the Instant Reset and Instant boot are implemented. When a boot sequence starts ( 1 ), preferably the system checks if there is an Image that can be used for instant boot ( 2 ), and, if so, performs instant boot by loading the Image into memory ( 4 ), otherwise it performs normal boot ( 3 ) and preferably saves the OS Image upon finishing the boot. The OS Image preferably contains also all needed info about loaded drivers and/or other loaded software and preferably also for example about the state of peripheral devices, and/or any other data that is needed for creating a sufficient snapshot of the computer&#39;s condition, so that the computer can be instantly restored to that state and operate properly by restoring or using the data from said Image. 
         [0152]    Regarding the state of the peripheral devices and resetting them, it can be handled for example in at least one of the following ways:
       1. Preferably peripheral devices can be preferably instantly reset to their original status as it would exist after a normal boot, preferably for example by improving the standard protocol of drivers so that preferably each driver and device has a function for instant reset. Another possible variation is that preferably each device driver can preferably instantly query the device to see if it is in a proper state or needs to be reset.   2. Preferably the system constantly updates some area in non-volatile memory or for example some buffer or stack with the current state of the devices, so that it can be preferably instantly determined if any of the devices was involved for example in a crash or needs reset.   3. Preferably at least one or more of the devices can be kept in its current state if the user so desires instead of resetting, so that for example if the user was in the middle of an Internet connection, the user can for example remain connected without having to reset the modem or Ethernet card and reconnect. Preferably during or after the reset the system asks the user if he wants various devices to remain in their previous states or for example it is defined as default before any reset is needed and the user can change it, and during the reset the system decides what do to with such devices according to the last given instructions. As in clause  2  above, preferably this is done by automatically saving the current state of the devices in a buffer or stack.   4. If any tests or resets are still needed in one or more devices which cannot be done instantly, preferably the system can automatically decide which devices are not critical and can therefore be dealt with in the background after the user can already start working, in a way similar to postponing the disks scan, so that for example if it takes some time to check a CD device, preferably this is done after the user can already start working, since the user typically will not need to access the CD immediately. This option can be preferably used also in normal boots or instant boots or when restoring from hibernate.   5. Preferably when a Reset or an instant boot is performed, the image is first reloaded into memory including all the drivers as if they have already checked and/or reset the relevant devices, and THEN the drivers are instructed to activate the instant actual reset on the actual devices, so that the state of the device conforms to the state that the driver is supposed to represent.   6. Preferably the data on the status of any peripheral devices that can be saved in the image includes also any plug and play data for such devices and/or for any other card or relevant elements in the computer, so that preferably no plug and play automatic tests are normally needed during booting. Preferably at least during any boot or reset that is not based on turning off and turning on again the computer (cold boot) there is no need for any plug and play check for example at least of installed cards since the devices and cards that are coupled to the mainboard do not change, so preferably the system can automatically identify if it is being reset or rebooted without a cold boot, and if so, it preferably simply uses automatically the plug-and-play solution or configuration that was used last time as saved in the image. However the user might for example remove the keyboard or the mouse or a printer cable even without turning off the computer, so preferably the system checks if such devices have changed. Another possible variation is that even if a cold-boot is done, preferably the system can check instantly if the configuration of devices and/or cards and/or other relevant elements has changed or is the same as the last image, and thus avoid for example any unnecessary plug-and-play checks and instantly choose the configuration used last time, preferably as saved in the image, if the configuration has not changed.       
 
         [0159]    The Image is preferably saved on the disk or other non-volatile memory with at least some preferably fast compression that allows faster transfer of the data to and from the disk. The system then preferably allows the user to start working immediately ( 6 ), and preferably immediately afterwards checks if there is a problem that requires Scandisk ( 7 ). If there is such a problem, then preferably Scandisk is performed at the background without interrupting the user&#39;s work ( 8 ), preferably with hardware support that enables it to finish even much faster, as explained in the reference to  FIG. 3 . Preferably the system allows a “Reset” function, which means that whenever the system gets stuck ( 9 ), preferably the user is able to press some special button or some key or keys on the keyboard in a way that causes the computer&#39;s memory to instantly Reset from the saved Image, without a need to go through a boot sequence at all ( 10 ). The special button or key is preferably sensed either by hardware or by some process which preferably runs below the Operating system and thus is not affected even when the system becomes stuck. After activating the Reset ( 10 ), preferably the system again checks if there is a problem that requires Scandisk ( 7 ), and, if so, preferably performs it again in the background as explained above ( 8 ). In addition, during normal operation, preferably any cut &amp; paste buffers are automatically saved also on the disk or other non-volatile memory, so that they can be immediately available on the next boot or after the next Reset. Similarly, preferably any currently edited files or windows are preferably automatically saved on the disk or other non-volatile memory preferably after sufficient minimal changes have accumulated (such as for example after at least 10 new characters have been added or changed) or every short while (for example every 30 seconds), so that they can be immediately available on the next boot or after the next Reset. Although something like this exists for example in Word, it is not available in many other programs, so preferably this is ensured by the OS itself. Preferably the System allows also “undo” in case the “Reset” button or command was pressed by accident, for example by saving an additional Image of the OS and of open windows/applications before restoring the boot Image. Of course, preferably any of the above principles or variations can be used also during recovery from hibernate and/or during any boot or instant boot, such as for example the instant boot described by IBM, since in these processes too reducing any waste of time on dealing with the peripheral devices and/or any waste of time for scandisk, can allow the user to be able to start working much sooner. However, there is of course a difference between instant boot or reset and restoring from hibernate, since in the instant boot or reset the drivers have to typically be reset to the initial state after boot, whereas when restoring from hibernate they have to typically be restored to their exact state at the time of requesting the hibernate. Another possible variation is that for example when restoring from hibernate or from Reset, the system can also automatically for example continue printing from the point it stopped, for example by saving the relevant information about the process of printing and preferably being able to query the printer exactly where it stopped for example in terms of characters and/or in terms of printed pages. Another possible variation is that the user can define or save for example the normal task bar itself or parts of it, so that for example upon any boot by default some Dos window will be open at a certain directory or for example Word will be open with a certain file, until changed by the user and/or for example the internet connection will be automatically activated and some browser windows will automatically open at certain sites. Another possible variation is that the user can for example define group-icons, which means that a single icon can connect a number of icons so that when the user clicks on the group icon a number of applications will open automatically, with or without restoring also for example their exact arrangement on the desktop. This way for example if some users are used to work with Word on the left side of the screen and some excel table on the right side, then clicking on the group icon or saving this as boot default will automatically open the two or more applications in the correct configuration. Another possible variation is that preferably the last sleep mode that was used is by default not erased and the user is offered for example upon normal reboot as one of the options the possibility to return as if from the last sleep mode, except that some programs that were running then will not be restored (since if it is a normal reboot then these processed have already been closed). For this preferably the OS can for example automatically add to the last sleep mode data for example upon normal shutting down and/or when specific processes have ended, the information that these processes are no longer relevant. Of course, various combinations of the above and other variations can also be used. 
         [0160]    Referring to  FIG. 2 , I show a preferable variation where for example any changes at all that happen for example on the hard disk or other non-volatile preferably fast-access memory ( 20 ) (and possibly even on other connected writeable media, such as for example CD or DVD or other backup media) at any time are completely undo-able at least for a certain time period (or as long as there is sufficient room to save the info needed for the undo), in a way similar for example to the undo feature in a single Word document. If this is implemented also for example for other connected media, the rollback areas for them can be for example on those media and/or for example on a separate rollback area or areas or on part of the normal rollback area within the disk (or other fast non-volatile memory). This is preferably accomplished by keeping one or more rollback logs, preferably backed up by appropriate hardware on the disk. The rollback can be enabled for example by creating a backup of each changed file or directory in another area at least for a certain time period or until for example the backup buffer becomes full and older backups have to be deleted automatically. Another possible variation, which saves much more space, is for example to keep a rollback log of all changes for example of directories, files, FAT areas, and/or any other data (such as for example even any low-level changes in disk tracks), so that any changes that were made on the storage media can be rolled back by simply tracing back the log of changes (this way only the changes have to be saved). Preferably this log or rollback buffer or buffers are encrypted and are highly guarded and/or are kept also in more than one place, in order to reduce the chance of its destruction by mistake or by some malicious software. This way even if the user has made a horrible mistake and the entire system has been compromised, even the worst damage can preferably still be automatically undone. Preferably the Operating System or a special Security System constantly guards itself and its files and preferably also these logs from any unauthorized changes. Another possible variation is that even commands such as for example format or re-partition or even low-level format are not able to destroy the rollback areas, so that for example at least a certain percent of the disk or other non-volatile memory is always reserved for the rollback info. Preferably the rollback logs or buffers or at least the most recent changes in them are always backed up in at least two or more separate places and/or also protected by additional encryption and/or redundancy data, so that damages can be fixed. Another possible variation is that the rollback feature is supported also by hardware, for example by a special area in the CPU or on the hard disk interface card, so that it is always available for example from a special ROM even if for example the system has been booted from another device, such as for example a diskette or CD or network drive. If it is an inherent part of the hard disk, this has the additional advantage that preferably at least part of the overhead of keeping the rollback files is run by special hardware for example on the hard disk&#39;s interface card, so that it does not burden the system or slow down disk operations. This can be done for example by keeping one or more additional read/write heads ( 22   b ) constantly near a special area of the disk ( 22 ) that is used for the rollback logs, so that accessing it for every disk change causes no additional access or seek activity of the normal read/write heads. Such an implementation can be also more secure since access to the rollback area can be limited for example on a hardware level, so that for example only an explicit command by the user entered directly by the user to the operating system through a direct command can restore changes from the rollback, so no malicious program can for example activate the command. Preferably when the user requests to restore things from the rollback, the following part of the rollback buffer is still kept, so that the user can for example also redo the “undo” by simply moving again forward on the rollback log, thus reinserting the cancelled changes. Preferably new changes to the rollback from that point on are kept on a separate part or buffer or branch, so that making additional changes from that point on will not overwrite the original “forward” part of the rollback, otherwise even changing one character after the undo can destroy the possibility of undoing the undo and returning to the original situation before the undo. (This is unlike for example the undo feature in Word, where undoing something and then adding new changes destroys the ability to go back to the situation before the undo). Preferably when going again forwards the user is shown the various branches that exist and can choose the appropriate one. Another possible variation is to apply this taking into account of branching also for example when the user moves backwards and forwards for example with web browsers, so that for example if the user chooses a different link after going back to a previous page and then for example goes back again, preferably the browser automatically displays the different paths available if the user moves forward again (for example in the form of branching chart). Another possible variation is to add such features also for example to word processing programs, such as for example Word, so that there too the user can choose which Redo he wants if there are a number of possible branches to choose from. Another possible variation is to add to word processing programs such as for example Word also an option that if the user for example types something by mistake while “overwrite” is pressed when he/she actually intended to use normal insert mode (which can happen quite often) preferably the overwritten part is always saved automatically for example in some buffer and preferably the user can press some button (or for example a combination of two buttons) which instantly restores the lost text as if the mode had been “insert” instead of “overwrite” (this can be called for example “retroactively changing mode”), instead of having to use cut or copy to save the new part, than use undo, and then use paste again. Another possible variation is that the user can for example chose some menu options or type some control which locks the Insert mode and thus prevents the user from moving by mistake into the overlay mode (which happens many times if the user for example wants to press the Del button but instead presses by mistake the Ins button), since most users almost never need to use the Overwrite (OVR) mode. Preferably the Undo in word processors such as for example Word is also improved so that even deleting the entire contents of the file and saving it is undoable. This is very important since in the prior art for example if the user by mistake presses “A a” (which stands for “mark all the text”) instead of “̂s” (save) and then presses backspace to delete one or more characters and then for example presses “̂s” again, the entire contents of the file can be erased and then saved like this, and then the undo does not work, so the entire file can become lost. Another possible variation is that for example when using cut &amp; paste if the user for example presses by mistake again “̂C” (copy) instead of ̂v (paste) (for example over the section that was supposed to be written over)(which happens many times since these are adjacent keys on the keyboard), the new copied text normally overwrites the previous one in the copy buffer. So preferably the user can press some undo key (for example ̂Z or some other control—specific for this) which brings back the previous copy buffer. This can be easily implemented for example by saving the copy buffers automatically in some stack. Another possible variation is that the user can for example automatically mark text or all the text within frames in the drawings (for example by a special control key, like ̂A, except that in the prior art ̂A effects only normal text outside the drawings) and/or for example the normal ̂A is improved to mark also the text within the frames in the drawings and then make for example global changes on these texts, such as for example absolute or relative enlarging or reduction, changing of font or color, etc. Similarly preferably the normal search within the documents is preferably improved to take into account automatically also for example the text in the frames within the drawings.m, 
         [0161]    Since the area assigned for keeping the rollback logs is necessarily limited, preferably the rollback file or files use one or more circular buffers, so when it is full the oldest changes logged are deleted by overwriting them with the new data, and pointers to the logical beginning and end of each circular buffer are updated accordingly. If the rollback is hardware based, another possible variation is that since it can preferably work even below the operating system level, the rollback is based for example on low-level hard disk data, such as for example simply recording all changes in disk tracks or sectors, etc., so that it is independent of any file formats used by the operating system. However, this can be problematic since hard disks today typically have for example auto-moving of bad tracks to a hidden pool of “spare” tracks, so this is preferably taken into consideration. Another possible variation is that the lower level hardware is also aware of upper formats. The variations of using special hardware for example in the hard disk itself are more preferable since this is safer and faster, and can be also immune to changes done while the computer was booted from another source, unless for example a malicious software booted from another source makes on purpose so many changes that the rollback logs become overwritten. In order to prevent this, one possible variation is that for example if the hard disk senses that the boot was not made from it, it will block all further changes for example after the log file becomes too full (for example counting the cumulative amount of changes since the boot), and request the user to boot from the hard disk. Another possible variation is for example some combination between the OS and the hardware support, so that for example there are two types of low-level write commands, one with rollback enabled (for example called RWrite, for Rollback enabled Write, or for example called SafeWrite) and one without, so that for example the operating system decides to use the safe (rollback enabled) write automatically for example when allowing changes in highly strategic directories and/or files, such as for example system files, “.doc” files and program source files. Another possible variation is that for example the Operating System or the computer&#39;s security system decide when to use the rollback enabled write and when the normal write, and for example takes care that normal files or directories are changed with the safe write, but for example swap files and other temporary files are changed with the normal write, in order to avoid burdening the rollback buffer with unimportant changes. This is less safe than the variation where every change is logged on the rollback files but has the advantage that the rollback buffer is reserved for more important changes, so they can be kept for a longer time than if also less important changes are kept on the logs. Preferably the user can preferably easily view or change the rules for which files or for example types of files or directories or for example types of directories should be kept in the rollback, such as for example saving especially rollback logs for example for doc files and/or program source files and/or for example ignoring large video files. Another possible variation is that for example if too little space is left on the hard disk or hard disks of for example in the specific area devoted for rollback logs, preferably the system automatically offers to the user to remove for example rollbacks logs of for example large video file if they were kept or for example less important and/or large and/or unimportant files. Another possible variation is that for example normal programs can also choose to use it depending on the importance of the files. However, a malicious program might for example try to create on purpose so many changes as to fill the rollback circular buffer and make it lose more real changes. Therefore, such behavior is preferably intercepted by the Operating System or a special Security system as a highly suspicious behavior (for example by identifying programs which keep rewriting the same files again and again apparently for no reason, or other suspicious or unusual behaviors). Therefore, preferably for example only the security system and/or the operating system can have access to the saving or restoring from the rollback buffer. However, if every change in the disk is automatically saved in the rollback buffer, then still a malicious program might create endless changes on purpose, so preferably it is intercepted preferably after a short time as highly suspicious behavior. Another possible variation is that for example each program or each installation directory has by default only up to a certain percent of the rollback areas allocate to it, so that it cannot take up too much of the rollback resources unless given explicit permission by the user (in this case preferably each has its own rollback circular buffer). However, a hardware based general rollback feature also can have a serious drawback that changes for example in one important file can only be undone by undoing changes in the entire disk, so for example to fix a damage that was caused to that file two months ago the user would have to undo changes of two months in the entire disk, restore the file, and then restore back the last two months on the entire disks—a very dangerous activity if anything goes wrong during the process for some reason. Therefore, a more preferable variation is that the hardware supported rollback or undo can be used also for each file separately or directory, for example by saving a separate rollback buffer or entry for each file, or for example each log entry contains also the name and full path of the relevant file (passed to it for example as a parameter during the write operation), so that the user can choose for example if to use an “undo” on the entire disk or only on a specific file or directory or group of files or group of directories or for example a specific partition. Preferably this path info changes only when the changes start referring to a separate file, so as long as the changes are in one file, no overhead of repeating the path is needed. Another possible variation is that for example the Security system and/or the operating system use the rollback log automatically for backing up any changes in highly strategic directories and/or files without hardware support. Of course, similar principles can be used also in other types of non-volatile memory that exist or will exist in the future, so that for example if some MRAM (Magnetic RAM) or 3D memory chips are used, preferably the rollback area or areas have independent access control for fast access without slowing down the normal access the actual data areas. These rollback features can be used also independently of any other features of this invention. Of course, various combinations of the above and other variations can also be used. 
         [0162]    Referring to  FIG. 3 , I show an illustration of a preferable example of using a separate area or areas ( 32 ) with separate read-write heads ( 32   b ) on the disk (or other non-volatile memory)( 30 ) for running one or more hardware supported FAT (File Allocation Table) areas. Preferably, during or after a fast-boot or a Reset that uses the memory Image (and/or even during or after a normal boot), if the FAT of the disks needs to be checked, preferably it is done in the background, after the user can already start working, since waiting for scandisk to finish can take several minutes and can be very aggravating to most users. Preferably the Scandisk (disk canning software) or similar software is backed up by special Hard-disk hardware, in a way similar to the hardware that supports automatic disk rollback, described in the reference to  FIG. 2 . Preferably this is done by using hard-disks wherein a special area or areas ( 32 ) is dedicated for FAT information, and preferably independent head or heads ( 32   b ) are used for read and write in those areas. Another problem with scandisk is that for example in Windows 98 scanning the drive where the OS is installed (typically drive C:) can take a long time, since many background operations can cause the scan to restart. So preferably even if there are problematic background changes at the time of the scan, preferably the system automatically keeps track of its recent scanning activity and thus preferably can jump back and forth temporarily if needed but does not need to restart the scan after such changes. This has the further advantage that also with normal disk activity any reading or writing of files can become faster even if they are fragmented, since less movements of the heads are needed to access the FAT area each time some jump is needed. Since each disk can have more than one partition, preferably the FAT areas of all partitions are kept in the same special area or areas ( 32 ). Preferably these areas are also guarded better in terms of security, so that for example any write-access to them is monitored more closely. Of course, various combinations of the above and other variations can also be used, such as for example various combinations of features of  FIG. 2  with features  FIG. 3 , so that for example both separate FAT area or areas with special access and other separate Rollback area or areas with special access are used, or for example the same special area or areas are used for both the rollback and the FAT. Another possible variation is that the disks or other non-volatile memory contain also one or more processors that can themselves conduct the comparison between the files and the FAT, so that it can be done in the background even with little or no consuming of CPU resources from the computer itself. Of course, similar principles can be used also in other types of non-volatile memory that exist or will exist in the future, so that for example if some MRAM (Magnetic RAM) or 3D memory chips are used, preferably the FAT area or areas have independent access such as for example independent communication channel and/or processor for fast access without slowing down the normal access the actual data areas. Similar principles can be used for example to speed up writing and/or reading for example on CDs, DVDs, and writeable or rewriteable CDs or DVDs (for example by using two or more separate laser beams—one or more for the normal data and one or more for a FAT or similar area), since jumping back and forth between the FAT area and the normal data areas is one of the things that most slow down such devices for example when copying a large number of files to them. Of course, these features can be used also independently of any other features of this invention. Of course, various combinations of the above and other variations can also be used. 
         [0163]    Referring to  FIGS. 5   a - c  I show illustrations of a few preferable configurations that can considerably increase the speed of the hard disk and/or reduce its power consumption.  FIG. 5  a shows a hard disk ( 50 ) with one of the rotating plates ( 53   a ) and its central hub ( 53   b ). As can be seen, the arm ( 55 ) that contains the read-write head ( 51 ) rotates part of a circle (along the dotted arc) in order to reach any desired track in the disk. Typically there are multiple such plates, and the arms go also between them, so that typically each arm can read/write the relevant sides of both the plate that is above it and the plate that is below it. (Typically all the arms move together between the plates, thus reading and writing the same tracks on multiple plates at the same time, however making for example one or more of these arms independent from the group can supply for example the desired independent heads for the independent rollback area and/or independent FAT area that were discussed above). By adding for example a preferably small fork with an additional head ( 52 ) the arm now only needs to move half of the way in order to reach any desired track, so that for example head  52  can take care of all the inner tracks and for example head  51  can take care of all the outer tracks. Since the arm itself is much more massive than the heads, this addition should not cause a significant addition to the total mass of the arm. An additional improvement in this variation is that preferably both heads can now read and write at the same time, thus doubling also the speed of data transfer. Of course, this is just an example and for example more than one additional head can be added in a similar way to each arm, so that for example there are a number of such forks (for example all at one side, or more preferably at both sides of the arm, to keep the balance, so that head  51  becomes in the middle. (Like head  51 , the added head  52  is preferably actually two heads, one for reading the appropriate side of the plate that is below it and one for reading the appropriate side of the plate that is above it, and as explained above this is preferably repeated for all the plates).  FIG. 5   b  shows a similar solution, except that the arm ( 55 ) is now stationary, preferably reaching the middle track, and preferably at its tip ( 54 ) is connected an additional preferably thin rotating plate ( 57 ) which contains preferably multiple read-write heads ( 56 ). This plate is preferably rotated by a flat step engine or voice coil, and its mass is now preferably much smaller and also the amount of rotation needed is much smaller (for example only ⅙ or the original arc, if there are now for example 6, preferably double sided, read/write heads). And like in  FIG. 5   a , preferably each head covers only its own range of tracks and all heads can preferably work simultaneously, so that preferably when the data is written it is also spread between the tracks accordingly, thus increasing the read/write transfer rate by a factor of 6, in this example. (Of course 6 heads is just an example and any other convenient number can also be used). The smaller mass of plate  57  and the much smaller range of rotation that is needed can thus also reduce considerably the power consumption and thus can be especially fit for example also for hard disks in laptops (mobile computers). However, using such a round small plate has a problem that the movement of the heads in relation to the disk is not linear, so that for example the heads that are near the innermost track and near the outermost track move much less than the middle heads, thus creating a large difference in the thickness of the corresponding tracks. Therefore, instead of a round small plate preferably the heads are on a special shape that corrects for this non-linear movement—for example some concave hyperbolic shape or cycloid shape or other mathematically appropriate shape (this can be done for example by changing the shape of the plate and/or by changing the positions of the heads instead of being all on the edges). On the other hand there is no such problem if the additional forks are added in the configuration of  FIG. 50   a —if all the tips with the head are on the same dotted arc (Although in this case also the linearity is not complete, the distortions are much smaller due to the remote axis of rotation of the arm, and therefore they are not important, since each head keeps using the same path for writing and for reading). The configuration of  FIG. 5   c  is very similar to that of  FIG. 5   b , except that the hub ( 54 ) of plate  57  is now outside the area of the disk&#39;s rotating plates ( 53   b ), thus allowing more room for the mechanics of the engine that rotates plate  57  and reducing the non-linearity problem, however the shape of plate  57  is preferably also corrected for linearity in this case like in plate of  FIG. 5   b . Both in the configurations of  FIG. 5   b  and of  FIG. 5   c  the heads can be for example just on one side of the plate (like in  FIG. 5   b ) or on both sides (like in  FIG. 5   c ), however if both sides are used then preferably the heads on the right are shifted in position compared to the heads on the left, so that altogether each head covers a different range of tracks. This has the advantage that more resolution in dividing the tracks between the heads can be achieved without putting the heads too close to each other. Another advantage of the configurations of  FIGS. 50   a - c  that since each head has its own range of tracks, another possible variation is that preferably the heads that deal with more external tracks use higher frequency and thus can write more data per each track in the external tracks, thus preferably creating more even data density across the disk, unlike the current disks, in which the amount of data on the outer tracks is the same per track as in the inner tracks, thus wasting a lot of space. This can thus in addition increase the available space on the disk on average for example by a factor of 2 or more. In this case preferably each head writes according to the highest density that can be used in the most inner track within its sub-range of tracks, however another possible variation is that each head can also increase its frequency when moving into the more external tracks within its range. Of course these configurations are preferably used for all the layers of the disk, so that preferably multiple such side plates replace the normal arms. Another possible variation is that, for example in the configurations of  FIGS. 5   b  and/or  5   c , instead of jumping into a certain position each time, plate  57  for example constantly rotates (thus removing the need for fast acceleration and stopping for each jump), and the rotations of plate  57  and of the disk&#39;s plates ( 53   b ) are specially correlated. In this case also, the shape of the plates is preferably specially designed to correct for various linearity problems and/or to create special more desired patterns of intersection with the disk&#39;s rotating plates. However this solution is much more problematic and requires unusual read/write patterns. Another possible variation is for example independent arms for each sub-range of tracks, or for example multiple independent arms (so that for example there are 2-3 hinges of arms sets instead of 1). This can for example also further increase the efficiency of access order optimizations, such as for example NCQ &amp; TCQ). Of course these are just examples and other configurations with similar principles can also be used. Of course, various combinations of the above variations can also be used. Of course, like other features of this invention, these features can be used also independently of any other features of this invention. 
         [0164]      FIGS. 4 &amp; 6  have been mentioned briefly in the patent summary and are just used for illustrating certain points in the prior art. 
         [0165]    Referring to  FIG. 7  I show an illustration of an improved computer case ( 70 ) in which at least the area that supports the external CD and/or DVD drives ( 71 ) is preferably rotate-able between two positions, so that the same case can be used either as a desktop case or as a tower case, thus giving the user much more flexibility in choosing the most convenient orientation without having to buy different cases. This is preferably done by making the case strong enough to support even large screen on top of it when used in the desktop orientation, and preferably at least the area that supports the external CD and/or DVD drives ( 71 ), is preferably rotate-able between two positions, preferably in 90 degrees (preferably only back and forth between the two position—to avoid excess bending of the cables), so that preferably the user can easily choose one of these two positions, at least by screwing the part when the case is open, but even more preferably the user can for example press one or more levers or buttons and then can preferably rotate the part even when the case is closed. Another possible variation is that for example the frame that holds the 3.5 devices ( 72 ) is also similarly rotate-able, although that is less important since for example zip drives, hard disks and normal diskette devices can work ok both in the horizontal and in the vertical position. Preferably the rotating frame can be for example pulled a little out to the front and then rotated when slightly outside of the case—so that the corners of the frame can rotate freely (preferably the inner part of the frame has a part with round edges), or for example the rotating frame has its corners always a little in front of the case, so that it can be rotated even without having to pull it out forwards. 
         [0166]    While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications, expansions and other applications of the invention may be made which are included within the scope of the present invention, as would be obvious to those skilled in the art.
