During the last two tournaments while running TD, I have had an issue where the keys on my keyboard were at times non-responsive while TD was running. I first noticed it when I could not pause the tournament with the space bar. Esc didn't work either. It was like there were two layers in a graphic, and TD was the back layer.
However, if moved the cursor with the mouse pad and input a left click, TD would then respond to keyboard inputs.
Any ideas what's going on?
