Alt-tabbing makes the game crash - I think it has been reported quite a few time already. There is basically no handling for switching processes. What not everyone knows, is what happens with a unattended Elemental game that has been alt-tabbed. Today, after couple of hours, my debug.err grow to a size of 2GB!! Of course it was constantly reporting "DebugMessage: ValidateDevice::Reset". Thus, remember: never leave your computer unattended with Elemental on.
