The conversion of music files from general MIDI to QuickTime MIDI has been improved, working around a bug in the way Netscape Navigator downloads MIDI files that could cause it to fail. Better compatibility with Kaleidoscope and Appearance themes. Improved the sound of the MIDI songs and added two new songs. Fixed a bug that could cause a crash if the monitor resolution was changed while the Bulb Factory window was open. There was no version 4 of Holiday Lights for Macintosh.
Bulbs can now flash in different patterns.
A Train Set bulb has been added, and all bulbs that were previously available separately have been incorporated into the main program rather than being installed as separate files. Holiday Lights now loads in the background so you can keep using the computer while it's starting up. Newly added music files are turned on by default. The bulbs are still visible around the edge of the screen when you use the Bulb Factory, and changes are shown immediately. The basic bulbs are now built into the program, so moving Holiday Lights to another computer without copying the Bulb Files folder will work.
