I am using Window XP, with QuickTime Player & Realplayer installed. Recently, the file manager stops me from moving any of the .mov file - keep poping the message that "the file is being use by other application........" I've closed out both the players, and cleared all the recent history in their menu. I also close/exit any of thme from the start-bar, and there is no player put in the "Start-up" folder. The .mov file can be played but cannot be "move, rename or delete". All existing .mov file in harddisk, USB thumbdrive or external HD have the same problem. But when I use the same USB thumbdrive in another computer, it works alright. Other media files like .gif or .mpg have no such problem.
Any help please
