Frozen screen with time moving
IPAD app. Has generally worked well, but on the two occasions it appeared live, but just failed to communicate. I tried sending chat messages to other player asking if he had seen problem and got no response.
Same thing happened to me yesterday, but on an old PC. I asked my opponent to move, suddenly the board reverted to an earlier position. Then after I lost on time, 1 of my knights skipped backwards across the board.
Very strange
A year ago, I lost 3 games that way with my IPad too. The worst of it is that 2 was winning games and the third at the 5th move.
I believe this is responsible for at least a small amt of online problems here http://www.nytimes.com/2013/03/27/technology/internet/online-dispute-becomes-internet-snarling-attack.html?hp&_r=1&
Twice over past four days (IPAD chess) in mid-game I submitted a move and the timer shifted to opponent showing highlighted move as expected. Opponent's move never showed and his timer never shifted back tom me, but I lost on time. Is this a known problem or an issue with my computer?
