I just got into the casino for the first time today. I bought coins and started a game of Calico Jack, but I can't figure out how to play. Actually the game might have froze up. The music continues but there isn't anything to click on and the [ESC] key doesn't work. I have to alt+tab to close the game.

Dealer was dealt a 1 and I had 18. But I couldn't do anything.

I attached a screenshot. Not sure what's supposed to happen here. Can't do anything. Happens on both tables.

Looks like the game froze. Did you try verifying the game files ? I had a crash after updating to 1.11 because a file was missing.
P.S. The topic is misleading. If you suspect a bug, then state it in the topic. This one suggests you simply don't know how to play Black Jack
