I set up a dropdown menu on one of the menu items called "resources" but when I click on another menu item like "about" or "sponsors" in IE, it pops up quickly and then disappears. Unfortunately it is not a feature. :-). This popping up does not seem to occur in Firefox or Chrome. This issue also occurred in WP 3.3.

Any suggestions for tools on how one might track this down would be helpful.
I am relatively newbie, so any help is appreciated.
