Conditional moves are set and acknowledged in the game then no move is recorded if my oppenent makes the expected move. Do I have a setting turned off?

I have set one today which worked fine. I don't know of any settings that have to be in place:- the only thing I would say is that if you are watching your games in real time you will find that there is a slight delay of a minute or so before your conditional is played. It not like the immediate response of a pre-move on a blitz site.
