The example code called StillDown which seems to be the right thing to do. 
 StillDown returns FALSE if the event queue contains a mouseUp event, 
which would handle the case you describe.  (You can also call WaitMouseUp, 
which does the same thing and removes the mouseUp from the event queue.)

Perhaps you can elaborate on why this does not work with QuicKeys; the 
code does take into account mouseUp events.

But you would have to add a call to GlobalToLocal because GetNextEvent 
returns global coordinates and GetMouse returns local coordinates.
