Update:
"Command bar won't hide" bug.
The bug is intermittent (hardest to track down).
Occurs with player.
It is reset by going from full screen to a window and back again.
Windows 7 host.
Windows XP guest.
Vista 64 bit guest.
I have not found a specific trigger for the bug. If I had Camtasia I could make a video. I can only ask the community to be on the lookout to see if it ever happens to them.
