as I played the game, I added the word 'quiet' but it wouldn't allow me to submit it. The submit button just appeared to be broken without explanation. The tiles weren't locked....I just couldn't do anything. I cleared the board and tried to submit quit and quite but it just wouldn't work. I was forced to submit a lesser word (tie) in order to continue. It was just strange that the game erred out when a q was used (b/c it's in the game).
