Hi,
I have to report this and also need advice on this. I have encountered several bullet games where my clock freezes right at the end moment when I am winning the game and suddenly I see that I have lost on time. It seems some player have found out a way to use som sort of a bug that freezes opponents time but still they win on time. Can some one advise me on this.
