Seeing as you do not see an issue and I rarely use snapshots I will hold 
off for a little while longer before delving into this much more.  By 
the way it did not matter if the 3D acceleration was on or off.  I tried 
it both ways before the guest and media manager was corrupted so much I 
had to restore from backup.
