There is a well-known bug in Netscape Communicator AND Mozilla. I've already reported them 2 years before, but nothing happened ;-) Just look in the .js files used by the html files listed above. I've written a simple function to preload GIF-files, which works fine with IE 4.X and Netscape Communicator 4.3 and higher. The sites changes the buttons on the event "OnMouseOver" with an animated GIF and replaces it on "OnMouseOut" with another animated one (both being buffered). While all browser preload the images fine, the display looks different and Mozilla really sucks up at this step: --- Details of the tests (the GIFs are NOT looped up, only single sequence) IE 4.X > : buffers correctly, animates correctly the GIF (only once)on OnMouseOver and animates correctly the 2th one on OnMouseOut (once too!) Netscape Communicator 4.3x > : buffers correctly, animates correctly the first GIF but displays on OnMouseOut only the last sequence of the second GIF-file. Not serious, but it nerves! Mozilla 6.1 SR 1 : buffers correctly, but displays all GIFs in a loop! I'll try to make the testing with Opera too next time. --- There are style-sheets an layout positioning errors on www.adwww.de made by Mozilla too, but I'll report them in a separate bug-report. If you guys want to go with that nice beast on serious competition with Micro$oft, you should remove such primitive bugs first. I'm not a die-hard bug reporter, my really occupation is dynamic web-building. But these bugs are very old and should be solved, they really annoy us in our businness trend ;-) Thanx for making Mozilla better, hope it will become something incomparable! Lev

Yes, we've known about this for a long time. Why not go vote for it on the other bug, since this is a DUP. *** This bug has been marked as a duplicate of 17126 ***

Formally reopening and reassigning to ImageLib component; will dupe again below. This is not JavaScript Engine, and I don't know enough about this to verify the dupe -

Based on Aaron's comment above, duping against bug 17126. If anyone disagrees, please reopen the bug; thanks - *** This bug has been marked as a duplicate of 17126 ***

Argh!!! Owner and QA need to be changed; reopening again; sorry!!!

Reassigning to ImageLib component, owner, and QA -

And duping again - *** This bug has been marked as a duplicate of 17126 ***
