Trouble With Firefox 2.0.0.6

Hi Everyone!

I am having trouble with my menu displaying properly in Firefox.

Everything appears to work OK in Internet Explorer, but in Firefox the menus don't disappear if you move the pointer off of them and once the sections are highlighted after being moused over the highlight doesn't go away.

Here is the link to my sight. Any help would be great. Thank you!
