Submenu help

I need some help here. I’m working on a Flash site for a client and have a menu that shows a submenu on mouseover.

I want the submenu to disappear when the mouse moves out of it. Right now you have to click it away, which is one step too much for the visitor.

I’ve got a sample of the menu here:

Hope anyone can point me in the right direction. Thanks!
