Auto-DJ mode does not engage and remains in Show mode

This bug relates to Build 20070927

Auto-DJ mode does not engage on selection from the dropdown menu. It initiates a track from AutoMedia to the playlist, but the GUI remains in Show mode. On completion of the track, it is removed from playlist, but Auto-DJ mode cannot be engaged again, while Show Mode remains greyed out.
