I had similar problem in one computer if report has more than one page.
I started deleting report fields
half by half to localize error. I discovered that after removing [ ] Blank if
zero checbox from report expression dialog C5 error suddenly disappears.

Should we go back to VFP 6 and wait for a service pack before using 7? Brings back bad memories of how much VFP 6 crashed before several service packs came out. If memory serves, VFP 6 finally became stable 1 year after its original release (was that SP3?).
