I guess this is a lot like asking someone "where did you lose you keys", but do you have any idea approximately when it stopped working? As I said, I never use those options, so I had no need to even think about it.
Those might be java scripts that run those routines. When I moved to the latest server, the guy who did the move for me loaded in a different java engine on the server. It's been giving me a few problems in the chat room because of it.
