I can't move any of my pieces at all?

Whenever I start a game, it aborts. because I CANNOT move by pieces. by the way i know how pieces move, and like 2 weeks ago on my other account i could move them, and then like a few days later the problem occured, i tried mozilla firefox. the problem was fixed, but again a few days later the same problem came back. i tried making a new acc (this one) and i have the problem. I've tried clearing my cache, but it's not working! i'm on a desktop btw.

Is it broken in Firefox and in Chrome for you?

Is it broken in Live Chess only or in Tactics Trainer as well?

i have the same problem on chrome    half way into a game and cant move

me too. In Safari 7.0.1

Refresh?  Maybe too many programs running when your playing. Check what is running and you may have to close it.

i closed out my chrome browser     went to msn  and was able to move.   bottom line is they have a bug with chrome browser
