I have Camino expanded but the tab for Plugin Options doesn't fit (?) and appears underneath the Admin options, thus throwing things out of alignment.

You will continue to have problems fitting large applicatons onto a small screen. Wraping is what is expected when the display will not fit.

On a 1024x768 standard resolution is should just fit (even with the extra tab for zenpage), depending on the default font size in your browser of course.

My screen is 17" @ 1024x768 MACINTOSH (sorry but better than PC view which is awful). Default setting for font.
