Win 7 , Quadro 3800FX ...CS6...
Has anyone else seen or experienced this little weirdness.
Minimise PPRO CS6...ande do something like go to Win Explorer, PhotoShop (or whatever)..close "whatever" to discover that PPRO Program monitor is full screen on Primary Monitor. As if CTRL-Grave (ctrl-tilde) has been invoked.
Mouse to top right where Program Monitor is located ( default position usually) and the PPRo interface restores itself as ( timeline , project panel etc..)
Never seen that Behavior on my system, I use an Nvidia GT470
