If your opponent offers you a draw, how do you agree to it?
 
Thanks!

In a Live Game, a line will appear in the chat window below the board that says "Opponent has offered a draw." There will be a bright red button to the right of the board that says "Accept Draw." Click that and the game will end as a draw.
 
In a Correspondence Game, Blue lettering below the board will say "Opponent has offered a draw" and just below that a button will appear that says "Accept Draw." Click that and the game will end as a draw.

Interesting. The bright red draw button did not appear as you described. There was a red button a little further to the right of the board, but it said 'Resign'.
 
Since the interface is Java-based, it ought to be browser independent, right? I'm running Opera 9.51.
 
Cheers,

Here is what mine looks like using Opera 9.52, Win XP, standard board size and Java 1.6.0_07.
 

why cant i cant draw against caissa?

Caissa is not programmed to respond to draw offers. However if the position is an obviously drawn position, she will offer a draw and you can accept it.
