page code would be helpfull for investigation..
P.S. just my guess check please that you have no nested forms.
Thanks for the hint.
The issue does not have anything to do with nested forms, but it seems related to the Sitemesh decorator that is being used. If I disabled it, everything works.
So I guess something is getting included that breaks under IE and Firefox in Linux.
I'll need to research it better.
