Serious bug

I'll be playing a 10 min. live chess game on an excellent connection, when all of a sudden I get a "You're connection has been interrupted." pop-up. I'm not doing anything else on my computer, so there's nothing to interrupt the connection. When it goes away, my opponent's move goes through. After this, every time, I cannot enter a move--legal, valid moves. I dragged one of my opponent's pieces and set it down (it does actually set down (*clink*) and then goes back real fast), and all of a sudden I could move.

This has happened several times now, so I decided to quit until you guys figured this out. I lost to a much lower rated player, because the process of "make some random move for my opponent, and then make your own move" was distracting me.

Thank you. Working on this...
