Having some issues with my site in IE7. If you check out the link below in IE7 you will notice there are some funky things going on with the main global navigation. I need to get this corrected as quickly as possible. Anyone have any suggestions on how I can fix this but not wreck it for all the other browsers that it already works fine in.
