I am testing my program on a new Vista computer with SP1 versus my old XP computer with SP2.
I launch a report from a VFP table with 200 records.
On the XP computer it takes less than 1 second to compile before it starts printing.
On the Vista computer it takes 22 seconds to compile before it starts printing.

Any chance SET REPORTBEHAVIOR is set to 80 on XP and 90 on Vista?

Also, what Sergey said.
