This is a known bug of VLC but there has not yet been found a fix, afaik it is not limited to a specific skin but occurs every so often with every skin.
any trac # or log available to start with ? which platform (Win or Linux) ?
I did some tests with latest 1.0-bugfix on WinXP. I found two different situations where vlc hangs :
#1: if using "Frame Next" ('E' hotkey) a lot, vlc ends up hanging with both qt4 and skins. This can be easily reproduced.
#2: sometimes, with skins, vlc does hang when quitting while a video is being played back. It did happen, but I could not find a way to easily reproduce it. Any logs or a bug description could be useful.
