CMS Made Simple Forums

I know this should be an easy fix but on a site i'm developing right now the drop down menu appears below all of the content in internet explorer 7.  It works great in firefox and I haven't been able to find a fix for this anywhere.  If someone knows of a fix please let me know.  Thanks

Here is the site: myescapades.net

Ok, I have it working now.  I applied a z-index: 10 to all of the items in the menu stylesheet and it is now working properly.
