[SOLVED] Drop down menu not working in IE9

Hi

I've just installed my first Atahualpa theme and joined the forum and would like help with a problem I've got.

I created a custom drop down menu in Wordpress 3.3.1. and it worked fine for a while in my browser (IE9). But as I continued to tweak my new fantastic Atahualpa theme, something I did has caused the drop down menu to stop working in IE9, although it still works in Firefox. Any ideas?
