Thank you, once again, Matt, for taking the time to help me out. That was a very clear explanation, even for someone of my limited PS experience. I have my CRT monitor set up now, and will try to follow the instructions later tonight. Hopefully, I'll be able to duplicate your edit.
I appreciate the assistance of the forum members very, very much. I know it has been said many times before, but I'm just awed at the overwhelming kindness on Steve's forum. I have learned so much in the two months I've been posting. I wish I had stopped lurking, swallowed my pride and jumped into the fray much earlier. I'd be a better photographer by now if I had!
