Can't delete a game

I challenged somebody about two weeks ago who hasn't made a move and is completely inactive in all his games. When I click on 'delete' however, I just get a box entitled 'delete' with a tick in it, and the next time I'm on the page, the game is still there. Is there way to delete a game that works?

When you want to archive or delete a game, you have to "update" your settings! So after clicking that you want to delete/archive a game, you should see an "update" button below your list of games!...

Great. That did the trick! Thanks
