small board

I prefer having the play board take up the entire screen, with smaller informational  windows on the side. All of a sudden, for timed games, the board has shrunk. There is huge black space all around it. It's hard to concentrate. For daily games, the board is full size. What happened and how can I fix it?

Try resizing the board using the double headed arrow symbol just to the right of the upper right hand corner of the board.  Click on the symbol and then as you move your mouse diagonally, the board will shrink or expand.  Not a clue what made it shrink in the first place though...

Thanks, baddogno. I will try that when I get home to my laptop.

What happened is I snapped the window with chess.com to the left of my screen and some youtube video to the right. That caused the resizing.
