You'd just have to tell us exact steps to recreate it. With as much code as possible...Like
CREATE CURSOR suchAndSuch ( C (15) )

then what fields to show.

Otherwise, it's all WAG. Um, here's one: do the reports that don't have scrollbars have unusually sized detail or group or header/footer bands?

Are you using 5.0a Build 415?
