[bug] Game doesn't respont to input up after screen saver, monitor off.

Windos 7 64 bit.  When I walk away form the computer, the screen saver kicks in, eventually the monitor shuts off. I have it set so it doesn't go all the way to sleep. When I return and enter my password to log in again, it doesn't respond to mouse clicks any more, although it moves on the screen.  I have to alt-tab and kill the process to start playing again.  Been an issue for several beta versions, thought I would mention it before the game went live.
