iceape (mozilla browser) and CSS of gallery website

["H.S." <hs.samix@gmail.com>]

Hello,

If I try to enlarge the fonts (CTRL+Wheel) in iceape of this website:
http://gallery.menalto.com/

the menus, or those little gray background windows, on the right hand 
jump into the middle of the page after a few magnification steps.

Is it just my iceape or is something wrong with the web page (bad CSS)?

This is on Debian Etch, fully updated.
