frozen screen

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?

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.

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...

Thank you. That's fixed it.

Now I can get on with losing

Sounds like the ideal way to stay cool this summer.
