I have notced that moving fast over the menus doesn't trigger all the
submenus opening, but never saw the menu completely locking up. That
type of bug would probably be caused by races, and the menu code is
all synchronous, so I find it a little odd.

I think the missing events might be because we use motion events to
trigger the submenus opening and the old code uses enter/exits. If I
can't reproduce the lock up, I don't think it is a serious bug, and I
really don't want to rewrite the menu code again.
