Thanks Diolma, A most encouraging reply from a user looking at the practical application of the software. I fully understand that the greater complications will entail some effort in understanding, but lifes like that. But what about the Manual ? The process of coming to an understanding is fine as long as the user has a comprehensive and detailed manual to work by. If this is not so, then eventually the learning process comes to a shuddering halt simply because one was not given the correct information. Would very much appreciate your comments on this very important aspect. Bill Soper.
