Yep - I'm already using a mouserelease handler, which is fine if you hold
the mouse down while you're doing the menu selection but doesn't catch those
situations where you click to display the menu and then move the cursor with
the mouse unclicked to make a selection. If the user moves on to some other
object without clicking the menu then it stays open.

While it's not ideal, for the moment I'm using a mouseLeave handler to send
a message to check whether the mouse is with the menu 3 seconds later - if
it isn't then I close it.
