Re: The mystery of vertical spacing

[Paul Hodges]

Ah, right - the number of systems on the first page didn't change, and I 
stopped there instead of looking at later pages as well.

I'll experiment with nopagebreak.  I already have a voice with just time 
signatures, skips and breaks, so that'll be a handy place to put them.

Thanks,
Paul
