I've done some searching both the forums and the web for a extension of extjs 3.x's Menu to allow menus to close on mouse out (but remain open if on a sub-menu) instead of just when the user clicks elsewhere on the page. I found a couple threads with solutions for this in 2.x, but nothing so far for 3.x. Is there anything out there currently, or can someone point me in the right direction to implement this myself?

Also, is there any type of built-in support for this behavior inbound in 4.0?
