    Add PointerMotionHintMask to fix mouse release.
    
    As suggested by Vincent Pomey:
    
        "I've found a problem with button release events being delayed of
        several seconds after playing a lot with the mouse. This is fixed by
        adding EventMask.PointerMotionHintMask to the AddEvents call."
