In Preferences->Video Settings, check 'fullscreen'.
Open a video and set to 'minimal view' and 'full screen'
close VLC.
Then open a movie and let it start to play.
Right-click anywhere on the video and select 'Quit'.
VLC will hang and show 'not responding' in the task manager. It never starts responding and I have to kill the process.
This is 100% repeatable on XP Pro.
It does NOT happen on Win7-64.
A clue to what the problem may be is that if I play the video to the end, or advance the video to the end by dragging the timeline slider, it does NOT crash if I quit VLC.
If I right click and select 'leave full screen' and stop the video, it does NOT crash if I quit VLC.
This is not new behavior, it has done this since I started using VLC at maybe version 1.1.
