Forum accessibility issue with Firefox

[lopri]

I use "Lucida Grande" as a default font for my brousers, and in Firefox, everytime I visit AT forums some links and boxes are out of shape. This doesn't happen in IE. It's also weird because Lucida Grande is a system default font for OS X and I haven't seen this error in Safari.

Any fix?

Actually it does happen in IE too. (just checked again) As soon as I change the font to something else, everything looks as they should.
