So yeah...here's the thing. About 15 minutes ago I was playing an epic 4v4 game against AI that was lasting over 3 hours...and at perhaps the last moments of the game (I was already attacking the Russians' base) I had to "alt-tab" the game and do something else (I won't say what but the person who made me alt-tab owes me plenty...). Anyways when I get back to the game, the whole thing just freezes and I basically had to force-shut my game, making that moment one of the greatest c0ckblocks of my life. After this c0ckblock, I wondered: how the hell does this alt-tab thing work? How come sometimes it crashes the game while other times it gets back to normal, and well?
