Scourge of War Boards

Is there a Hot-key or keyboard combination for exiting the game?

I'm asking as twice now my display driver has stopped working. Normally when this happens, Windows pops up a window that system has recovered. But it appears this doesnt happen when I'm in the game. As a result, my screen is black and I'm unable to recover without having to turn off the computer entirely.

I tried Esc then Q, but that doesn't seem to work.

Thanks

Alt, Tab, close the game from the desktop, or,

Ctrl, Alt, Del, this brings up the Task Manager, navigate and close the game with it...close Applications.

I had tried both of those but neither worked in these situations. It's happened twice today while going through the Cavalry Tutorial. I'll try the Inf Corp Tutorial and see if same thing happens. '

Thanks for suggestions though!
