Drop Down Menu issues in Firefox 1.5

My drop down menus won’t work with Firefox 1.5 or Opera, and I can’t seem to figure out why. Here’s the URL:

The menus work fine in IE and FF 1.0.7, but not in FF 1.5 or Opera. The problem is positioning. The JS loads fine in both FF 1.5 and Opera, but the drop down menus are being positioned off the screen(I can tell because if I mess with the margin settings in the css, I can get the bottoms of the drop down menus to appear at the top of the screen). The problem must be in the Dom-build.js file, becuase both FF and Opera 8+ will load this file. I tried to just put an offset in that file, but it will move all drop down menus and submenus by that amount, and the dropdown menus are lining up with each other at the bottom, leaving a gap on the shorter menu. like this:

-subject- -subject- -subject-
-menu-
——- -menu-
——- -menu- ——-

The worst of it is, this menu systems works in FF 1.5, if you check it here:

But I can’t get it to work for me, and I have been going over it for days. So if anyone can think of why it would work in FF 1.0.7 but not FF 1.5, it would be greatly appreciated.

Thanks
