It's been a long time since I last played CTP. Contrary to mardukes, I never had any programming bugs, except that from time to time it seemed it didn't want to run at all ! But I changed my OS, maybe that's the reason...
Anyway, even if I'm far from being a real specialist of CTP, I'd be glad to help (however, don't expect immediate answers, I travel a lot, to places where internet connections are rather difficult).
