I don't know if anyone already knows about this or is already using it, but this little app is awesome. It lets you play in windowed mode but full screen, allowing alt tabbing to function much smoother. I've been using it the past few days and have not had a single issue with my games crashing or hanging by alt tabbing. http://westechsolutions.net/sites/WindowedBorderlessGaming/manual
seems that I can never alt-tab when I want to, but in the middle of combat clicking on something on my other monitor and getting my desktop is a breeze!
