I've been playing slashem in a command window using the ascii interface for a while now.  I always had to start the game in a window then maximize the window to prevent the font from being wonky.

Now when I create a new game in a command window it plays fine, but when I maximize the window my keyboard stops responding.  I can still tab out and I can go back to windowed mode but the keys never start working again.

Has anyone else experienced this problem?
