With the added delay to the popup menu loop, it's much more likely that each
iteration will see several events, so pop all events from the queue each time. Of course, we still only need to check the mouse position once. Warp the mouse back to neutral even if we're trying to go past the first/last menu entry. svn-id: r20918
