"When I attempt to run the same project in VFP6 the same problem occurs.
This project was running smoothly for years prior to this."
So now the problem is now being experienced in BOTH unmodified VFP6 code and in the VFP9 conversion code.
Hopefully you have kept both the version-specific Project files and the compiled EXE's separate for your various version testing. If not, then do so now and re-test.
If, with appropriate separation, they both continue to misbehave, that would sort of eliminate the code migration as having been the cause.
Therefore the next question to ask when situations like this occur is -- What else has changed?
If things used to run one way and, with no code changes having been introduced (at least into the VFP6 version), they now run differently, then SOMETHING else has changed.
What else might that be? You might have to put on your 'Sherlock Holmes" hat to find out.
With more information we can likely assist you better.
Good Luck
