The problem that i'm having is that when i leave my pc playing a movie over night as i usually do, next day i'm unable to go from full screen to windowed with double click in the image... i always have to do ALT+F4 to close it... the problem doesnt appear during playback or if i dont leave it too long in full screen. it's just an anoying thing that never happenned in any WMP. just liked to know if it happens to everyone using vista or is it just me
