thank you for your answers.

Tom, I am using the default theme and brought it to the front.

As you noticed, in IE it doesnt even show the drop down menu now, and if you have a look at the site with FF, it displays fine, but when the drop down links are clicked, the following error message comes up; "firefox doesnt know how to open this address, because the protocol (c) isnt associated with any program.

I really hope we can figure this one out...
