cheating

i wouldn't bet money on this system!first there's something wrong with the drag , stops short , sometimes !!so instead of a cheque mate ,on a queen move, the queen gets taken , for example.you are in a great position , let's say ,then the game gets interrupted, & you notice all your time has gone, or your time seems to go twice as fast as your opponents....what's going on here, fishy & infuriating....& great if you're a professional cheater who doesn't like losing . I 'm playing for fun , so i can just about take this pain.....but my pride & ego can take a beating ,when i get killed ,in a game like that!!!!!!!!!!!!!!!
