I've been froze out of at least 3 of my Mentor Lesson today, so I just sign off then log back in to resume with a new lesson. It is a small aggravation but my lessons continue, I'm still breathing, life goes on, and I can live with it.
frozen screen
Unfortunately, signing off then back in doesn't seem to clear this for me. I've even tried it on a different laptop, but it's just the same.
which game please? - nevermind, found it: http://www.chess.com/echess/game.html?id=31797624
investigating...

I am in the middle of a game (vs herghost), and the screen seems to have frozen. It shows my last move in yellow, but tells me it's my move. I can see from the FEN and popup that herghost has moved, but can't make my move.
I am using firefox on a mac. I have reloaded the page, rebooted the browser and logged off and on.
Any ideas?
