Thanks so much for the suggestions. Problem solved! There is nothing Mudcat cannot unravel!

I had not even thought about looking at 'print preview' since I was nowhere near printing. But that showed me what was going on. I just did not realize that the staff would just keep going off to the right like a tickertape, because when I would 'bump up' against the right side of my window, nothing moved that direction. After looking at Preview, I realized I could manually scroll to the right, add some more bars and keep going. Just a weird interface I hadn't seen before...

You all get Good Samaritan points and may sing for the class!
