When I start MP in fullscreen mode and in MyVideos use X to toggle back to the UI I don't have the preview window in the lower left corner. Toggling back to the movie works. When pressing B to stop the movie the GUI freezes. You can still hear the cursor move, but you don't see it.

To reproduce:
* Start MP in fullscreen mode VMR9 enabled
* Goto MyVideos
* Start a movie
* Toggle to UI with X --> there is no preview window
* Stop the movie with B --> GUI will stop beeing painted
