Magento

I need help figuring out why my Nav Bar displays correctly in Firefox but not IE7. If I could use firebug in IE7 it would be easier to isolate what the problem is, but I can’t so hopefully someone can help me nail it.  The page can be viewed at http://www.moodandmind.com - Thanks ahead of time!

Well, I cheated to compensate by assigning a fixed height to solve the problem, so it will be impossible to see the difference now, but my nav menu won’t be able to spill onto two lines if someone has very large text.
