I started to enter a new tune on a new staff the problem was the new staff came up about 3/8 of an inch wide. the only way I could enlarge it was to go to a print option of about 45
Wha Happened ?????
From your description, it might be anything.
BTW, if you have 45 levels in print preview, you have a strange printer. I only have 9
3/8 inch is more or less the size of a staff at zoom level 1 on my screen.
Have you checked the zoom level?
