The new look

Have you notice that with the new set-up, if you are playing chess you cannot see your opponent messages?

What new setup?

is it just him or you in kid mode or you just toggled chat or something there is nothing new

@Berettatiger it's either zen mode or you accidentally went into kid mode

The chat appear under the chess game

@Berettatiger Can we get a screenshot?

How can I go back to the way I had before???

I don't know how to take a screen shot

@Berettatiger is not in kid mode,if he was he can't post In forums

Make sure to check your preferences.

Scroll down here you should be able to see whether Zen mode is on or off. Taking a look at some of the other tabs might be helpful as well.

Also, zen mode can be turned on using the "z" hotkey, which you might have accidentally pressed.

Hope this helps
