Some times when stopping a TV Recorded Show, the last frame remains on screen and MP never gets back control to image on screen, I can only see infos on VFD so I go to home and reduce MP into tray area. the only thing I can do is click the icon on tray and select "Exit"...If I resume it from tray the windows desktop image remains on screen like the last TV Recording Show, I have to close it and Exit then restart MP...this happens only sometimes...seems that MP loses control of the main graphical surface...anyone else is experiencing these problems? I have NVidia 83.??? drivers...is it better to upgrade to latest driver?
