ive had this quickcam attached to my computer for a while now, and i havent used it in over a few months. when i go to use it, every time i open the application it says that the "logitech quickcam express is currently in use by another application"(something along those lines im too lazy to type it word for word.) has anyone else had this problem? what did you do to fix this annoying problem? i have no idea what other application could be using the camera... please help, all help is appreciated.
