GetMouse, WaitMouseUp, and Button I don't think use the event manager, but
I could be wrong. I know for a fact that StillDown _does_ use the
event manager to see if a mouse up event is pending (If a mouse up event
is pending, then the mouse has been released and reclicked. Thus a
StillDown boils down to a Button & Not( EventAvail( MouseUp ))). StillDown
does not remove the mouseUp from the queue.
