I am not too familiar with vbulletin's code, but when drop downs on my joomla site do that it is the "position: relative; somewhere in the css that is causing this.

This happens a lot in IE for some reason because both are "position: relative; ....

You can also simply add a new <div> around the existing menu and defined the new <div> in CSS with a high z-index , something like this:

CSS:
#iefix {
position:relative;
z-index:1000;
}

--------------- Added [DATE]1348806028[/DATE] at [TIME]1348806028[/TIME] ---------------

You might only have to drop the position:relative; from what ever is overlapping the menu's dropdown.
