Pages filling unevenly
I'm scoring 12 staves per page. On some pages the image fits nicely re: page margins, staff spacing, etc.; on others, everything is different so the margins appear larger, the staff spacing is tighter, etc. I'm aware of 'last page fill" but can find nothing re: odd and even pages having the same margins & staff spacing. It seems the program wants to fit random sizes on any page. Can anyone advise me?
