Menu Drop Down Problems

Since we upgraded to 3.3.2, I’ve had problems with the dropdown menus. When you roll over the main menu choice and the dropdown appears, the moment you try to mouse down to the dropdown it disappears. You have to roll over it a couple times before it sticks.

Any ideas? I have searched through every page where a “menu” item appears and cannot find anything that indicates a change which would cause this issue.
