The Dink Network

I got to the blackjack tables, and played one round successfully (well, I lost, but I was able to finish playing the round), but when I tried a second round, the game stuck. I can use the arrow keys to move back and forth between "Hit Me" and "Stand", but it won't accept any other input, including the Esc key to go back to a earlier save, or correctly quit the game. If I just quit using Command-Q, then it automatically loads exactly where I was next time I start the game, leaving me frozen. I even tried uninstalling and reinstalling the program, but even that didn't work. I still come back into the middle of the blackjack game. Can someone help me get unstuck?

I'm on Mac OS X, using version 1.4.7 of the game, and 1.0.3 of the DMOD.
