What's with the yellow squares?

Aug 6, 2013, 3:32 PM |

Sometimes when I play, each move is now hi-lited by surrounding the squares with a yellow border.  This is new, and I find it extremely distracting. 

I don't see any way to turn off this feature, and if this becomes standard at this site, I will find a new site to play on.  Does anyone have any insight into this?
