If I find people directly linking to the zipped tube files, I will have to reinstate that. If you don't see this button on the tubes pages, then you don't have a browser that is capable of viewing Java Script. You can get an updated MSIE or Netscape browser.
More information is available here .
Some, but not all, MSIE version 4's will work. I have not found any of the Netscape version 3's that will work. If it isn't working, then you may need to clear your cache file of your browser before trying to download again. I can't say how often search engines and AOL's proxy cache refreshes the copy of my page that it delivers to your browser. You will need a program, like WinZip , to unzip the files.
