QT player and controller

[Kurt Kaufman]

I am using a player object to play externally-referenced videoclips.  I 
have the buffer turned off, "receive focus" turned on, and "show 
controller" turned on.  In the RunRev editing environment, the 
controller responds to mouseclicks, etc. for volume adjustment, pause, 
on so on.  However, in the standalone, the controller does not repsond 
to mouse button activity.  Why would this be?
thanks, Kurt
