Why do I always have a U even though im not using any word processors, or web surfing. How could I get rid of it?

You may not done what you have listed above, but if you just take your mouse away from the chess board many time during the game, you will get a U. Try this: don't use your account for a couple of days, see if that solve your problems.

Good luck

That's ridiculous! For somebody who don't use sw and got kick out of the table because his/her mouse is away from the window is a totally uncall for. And on top of that, you guys recommend not using the account for a couple of days?

A better solution would be to fire the sw detector programmer, and hire a new one!
