Like I said, it is technically possible to cheat the clock in live chess. 

The only debate is are there any chess.com members with the technical acumen to purchase and install a $20 piece of software written for Windows OS.

Today, I played a game against "Abehrad" and had pretty good internet connection but suddenly my time was in seconds. I played couple of games with him and it was the same issue.  This is the same issue I faced which others have reported.
