You nailed it. I just got back from downstairs and that's the first thing I checked. I had played around with it wondering what would happen if I turned it on. I guess now myself and anyone else who reads this thread will know, don't use clickety-clack with a diesel engine. I'm going out on a limb here and wish for anyone to correct me if I am wrong, but this would be a steam engine feature? If so, why is it even a choice when using a diesel engine? The pull rope icon isn't a diesel engine feature, so MTH doesn't allow it to be shown on a diesel engine screen. All you have to do is program the software to wash out any settings that are steam engine specific. Chuff rate would be another one.
