Built on the X library by Mike Foster from Cross-Browser.com. My modified version (with all the built in D-Fader functions) is available here.
Tested on IE4+, NS4+, and Mozilla/Gecko/Netscape 5+ on Linux and Windoze.
FYI: Netscape 7.1 seems to have some BIG BUGS in it. Don't upgrade just yet because everything seems to work good in 7.02. Same goes for Mozilla (1.0 works fine, but 1.4 and 1.5 don't). I've filed a bug with Mozilla's Bugzilla.
