Sorry to bring up an old thread, please move this post to a new thread if necessary.
I'm running 188.8.131.526 (gold version). On WINDOWS XP.
I have both "disabled repositioning of dialogs and controls" and "hide menu bar" enabled.
However, I can still right click the empty menu bar at the top, and add in new toolbars.
On a related note, it would be absolutely brilliant if the following option could be added:
"Total Lockdown - only exception double-clicking a song to Play Last."
This would make for a 100% true jukebox setup
