Hi!
We're remaking the company website, and the designer wants a big background image to cover the entire site, and on top of that, he wants a sort of accordion menu. Like this:
http://anders.nomadiz.se/nomcom/

It works fine in IE6 and Safari for PC, but when you try it in Firefox, the accordion menu messes up the background (FF 2.0.0.7), and when you resize the window ever so slightly, it looks good again.

Is there anything to do about this, or do we have to rethink it?
