Tried printing with PrintTool....prints fine when using "saved data", but crashes when I try to refresh.

I'm thinking it's one of two things:
Parameters: Report has parameters. They aren't fancy, don't look up info and aren't cascading.
ODBC Driver: I've noticed there are some things I can't do in Crystal while using the Adagio ODBC (like using formulae in linking), perhaps one of the Crystal functions I've used (inadvertently) is causing the ODBC read to fail.

As an immediate solution, this client is buying Crystal for themselves and I will recreate the report on site.

I'll keep you posted...
