Mac, I downloaded your program. It hung up on me, so, I went back and put a stop just before SCREEN 12. It ran fine, up to SCREEN 12. I pressed F8, to step through the program and try to locate the problem. It went through SCREEN 12, and went from a window to a full screen, with the cursor at the beginning of the next line. And, it froze, right there. I tried that twice, with the same result. I changed to SCREEN 13, and...it froze there again. Any clues? Thanks for your help.
