while no one has time to work on the real problem behind (described by  
Jonathan), I would suggest a hack solution: instead of a copy of an image  
(as suggested by someone), just turn the display off while the selection  
is moving? doesnt' solve the real issue, but avoids some  
dropouts/slugishness.
