First a note that this problem has 'eveloved' from here (it now looks more like a general CSS problem, than just a Firefox PR1 & the validation script issue. So this forum now seams more suitable)

Somehow the css I have on my form pages has stoped the buttons at the bottom working in all browsers except IE. If I disable the css in Firefox (using the Web Developer plugin) the buttons work fine. I have tried removing the "formbutton" class from the buttons (it makes them all a uniform size) with no change, I also removed the class form the css, which also did nothing.

Anyone had this problem before, and have any tips on how to sort it out?
