CSS friendly menus working in IE 8, Firefox but not IE 7

Apr 1, 2009 at 8:11 PM
I have a site up where the css friendly drop down menus are hiding behind other content. The z-index is set on every div I can find and it still does occurs but just in IE 7.

How is one to debug this behavior. I have used firebug to go through the generated code and the css but I dont see anything that should cause this.   www . compsciservices . com
is the website with spaces added.

Can anyone point me in the right direction.
