It can't be a coincidence we all got the same problem with 1.1.0 release
I'm running Windows XP Pro SP2 and after closing VLC with the "X" button, i can't play another vid until i delete the remaining process vlc.exe in the task manager (which i keep constantly opened for that reason since i installed 1.1.0)
Is it possible this problem could be linked with the vlc tray icon ?
Because i don't remember i ever had a vlc tray icon in the precedent releases
Now, with 1.1.0, i noticed a "default" ticked vlc tray icon : the icon remains in the tray icon even after closing vlc
So i went in the preferences to uncheck that preference ("no tray icon", i never did that with precedent releases) but even with the unchecked preference, vlc.exe stays in the task manager after i close it with the "x" button (please note this problem doesn't happen each time vlc is closed, so this fact complicates the problem)
I'm sure the developers will find same problem if they use vlc on XP, and other persons have noticed it too in other topics
Vlc staff will soon fix that issue, that's for sure
PS: Thx to Wraythex for suggesting the perfect Ctrl+Q workaround
