I noticed that if I leave QuickTime open in fullscreen and then my screen is locked, I have no way to unlock it:
- Screen is completely black but for the mouse cursor.
- I can move the mouse across the screen and the attached external monitor.
- Both the external keyboard and the laptop one have no other effect than to make the system beep by each keystroke.
Is there a better way than to force power off the machine to unlock it?
