Thoughtful and helpful responses here. Thank you. I have decided against XD for now. I'll leave that for the experts, whos work I admire so much. I already have UF, and I love it, but haven't played much with it since I found Apo. That has kept me busy for weeks. Time seems to be the biggest factor in my impatience regarding learning new things. Nick, I appreciate your response, and I know that I will ask specific questions when I'm better able to form them in my mind. At the present time, I'm dazed and confused by Apo scripts. I made some minor changes to one, and liked the results, but it was purely an accident. I know nothing about what they mean. Is there somewhere that I can read about the scripts and the various parts so I could perhaps make something intelligent of my own? Again, thanks to all of you who answered. It is obvious that I'd be way over my head with XD. Bee
