I need help with the page layout

I need some help.

I have created a choral arrangement of a hymn (I split it into 4 staves). Everything works great, playback is great. However, each page has the staves separated differently. To explain: On the 1st page there is a nice 1" or so gap between the 1st set of 4 staves and the 2nd set (2 to a page). On the 2nd page there is a huge 3" or 4" gap. On both the 3rd and 4th pages they are too close together.

I have tried to move them closer together using various tools, but not without severly damaging the rest of the piece.

Here is the file for downloading:

Like I said, everything else is great. Just that visually, it looks sloppy.

Anybody have a minute to take a look?

Thanks,

Dan
