occasionaly. nothin you can do.

Are you running any HUDs, etc? I run PokerOffice and about 1hr into a game, when the action comes to me it will close the table window. This is a known issue for PokerOffice w/ PokerStars and they are fixing it to my knowledge. This could perhaps be your problem if you are possibly running PokerOffice or another program with a similar issue.
