showing key squares


I guess your problem is new. Many people complained that the key squares were not showing in V3.
Yours is the first complaint I've seen asking to not show the key squares. That must mean that they attempted to fix the problem. Waiting until you've already made a bad guess seems like a good idea to me.
I guess you can't please everybody.
Your reaction seems a little strong.
/ How many wrong guesses do you think there should be before they show you a hint?
