It's due to lag. Don't accuse your opponent of cheating when it isn't the case. It isn't good to be a sore loser.

Dude, it's not lag; I know the difference. If I try to move, and my server won't let me, that's one thing. When I SEE my opponent's clock run down, then suddenly ALL of the time is back on it, while my clock has run down without it even being my turn, that sounds a lot like somnething else.
Can you show any example of the server preventing you from making a move? Perhaps the move you tried to play was illegal.

It IS lag, you're just misunderstanding how it is being applied here.
There isn't just one clock, there's three - the one on your browser, the one on your opponent's browser, and the one on the server.
When you make a move on your browser, your opponent's time on your browser's clock starts going down. But your opponent's time on your opponent's browser doesn't start going down until they receive the move from the server. But it is the server's clock that really matters, and if there is lag between your browser and the server, then the clocks on your browser are not going to be correct until the server updates them. That's why your clock suddenly goes down while their's goes up - the lag time is counting against you, but your browser doesn't realize that (and is counting the time against your opponent) until it gets the correct times.
Exactly. The link I gave explains everything in detail.

Those are some harsh words...
There is no program that could possibly do this. There are three types of cheaters: One that will beat you in ten moves or less, one that will play fairly until they get way behind then lose their queen. At that time their play style will change and they will slowly but surely catch up and beat you. The third is hard to spot. They will start out fairly until they get behind, then play best moves until they get ahead, then play fairly again and keep repeating that until they barely beat you. Then they will whine and ask you how it is possible to cheat at chess. They'll call you a poor sport and report you for whining.
