I have a client that I recently switched to VFP9 SP1 that is getting this error about one time in ten when printing (sometimes more often, sometimes less). The report is a simple one page letter.

Source line:
report form (m.reportname) next 1 to print noconsole

Error: 1733 Class definition for output type 0 is not found.
message: DO (_REPORTOUTPUT) WITH 0, __ReturnObject

This happens from three different computers.
The report does NOT have a printer enviornment. I also checked that expr, tag1, tag2 are empty.
enginebehavior is 90
_REPORTOUTPUT is "C:\PROGRAM FILES\COMMON FILES\MICROSOFT SHARED\VFP\REPORTOUTPUT.APP"

I have switched them back to enginebehavior 80 for now. Does anyone know why this is happening?

Thanks,

Paul
