Latest MPC-HC player installed. I will be watching a show (fullscreen) and for some unknown reason it minimizes to the taskbar. Click on the taskbar icon and it goes back to fullscreen. Doesn't do it all the time maybe once in every 4-5 shows. Nothing else comes up. I've checked all the settings and can't find anything amiss. This started about 2-3 months back. Anyone else run across this problem? Win7 Pro x64
