Plain green is the best
also please try to upload an image, i really don't get what bug exactly you mean.
btw. i know there are some little glitches on DB with mozilla. but tere were just the two methods:
a: make it IE konform
b: make it Mozillaconform and produce glitches on IE
and as the majority uses IE i won't change the descision.
If you can tell me a different code which works on both browsers, feel free to do so, i didn't find one when i worked on that problems last time
