blank page prints after group (sometimes)

[leahf via AccessMonster.com]

I have report of students with the class_id defined as a group. "Force New
Page" is defined "Before Section".

Whether I have a page and a group header defined (they can be the same anyway)
or just a page header defined, I am getting the same problem:

27 students can fit onto a page. However, if there is a class of 25 students,
the next page is blank except for the header. (I have not seen a class of
27 students so I have not tested that yet).

I can't seem to find a way out of it. Where I am I going wrong?

Nevermind. I originally had a footer but then deleted the information
without deleting the actual footer.

Many thanks anyway.
