I think it is a timing issue w/ the way PDF files are created and the way it creates temp files and then renames them. The second REPORT FORM was not letting the first one finish its thing.
This sounds like the error often encountered with HP printer drivers; try adding the following code after each REPORT FORM:
DECLARE _fpreset in MSVCRT && only needed once
=_fpreset()
This resets the state of the FPU and MMX register - some printer drivers do not clean up after themselves, leaving the FPU in an unstable state. This clears the FPU. You should call this after every printer operation.
VFP SP6 addresses this itself.
