I have had problems with the 'stop playing' button not working in numerous frames, i think im right in saying that this has happened to a couple of other people.

There is away of getting out of it by both people clicking stop playing then going back into the game but it doesnt seem to be working occasionally if one person clicks stop playing.

any ideas why this may be happening?

I notice if you click stop playing you have to leave the game and re enter the game to play again becuase it buttons (Play,Chatroom) are not there

If thats what you mean

it means if you click it too early you either have to leave or ask opponent to watch to fix it

cant help here havn't experianced any problems with this
