Thanks Raj, that does help. I didn't know my site looked so horrible in Konqueror, lol. (Looks like Konqueror has a bit of trouble rendering text shadow.)
It doesn't look like you had javascript enabled in Firefox, did you? It might just be messing up.
As you probably noticed, the Opera bug for some reason adds to the total height of the page whenever the scrollbar is scrolled down further. I can't figure this one out, and it seems to only affect Opera.
