New idea about it. Some days ago i just set for all boards letters and numbers outside of it.. that might have moved the board?
Mouse doesn't work correctly.

Seems fixed, i'll tell you something later on. However, the only addon I have is chess.com toolbar...

No. Not fixed to me, this gets me kinda nervous. ( Well, i'm nervous on my onw, and failing because of the mouse doesn't help very much )
Would you tell me just how to go back to default settings for every board ( online, live, tactics, mentor ) so i can hope to be able to play normally again ?

And, note that i use chess.com on 3 different computers. None is safe from the mouseaint'working problem.
I've been having a problem with my cursor when I click on the piece to move the cursor jumps 2 squares higher and I can't let go of the piece I tried to pick up.

Well, I just set everything as it was at start ( no letters and numbers in or out of board ) and it seems to be working. Still have to try live board, i will tonight.
Mine seems fixed, how's yours now?
I think I did nothing about it...
