CKEditor maximize button with firefox on Marinelli theme doesn't work

When viewing the site with Firefox 3.6.14 and using CKeditor 3.5.2. and Marinelli 7x-3.0-beta5

Safari, Chrome have no problem in maximizing the editor window to the whole browser, however when I use firefox The buttons all scrunch up to the left side of the screen. If I change themes to Bartik 7 or Garland 7 or Seven 7.0, this will work fine.

Anyone have any ideas?

Thanks
