Firefox layout problem in Atahualpa – need help

Hello,

I’ve added some custom elements to the Atahualpa theme, and have not been able to fix a positioning problem in Firefox. There seems to be a problem with the “logoarea” table, which stretches too wide and throws off the entire layout (I think). The layout seems to be working fine in other browsers (I haven’t yet tested them all though).

Any help would be greatly appreciated, thanks!!!
