Marcia,

DDEML.DLL is the DDE Management Library that can serve as the DDE API. An application can use it, but can also choose to bypass using it, and deal with messaging services directly. I think it's significant to the problem, and may indicate that my premise is correct. My tests with FPW 2.6 and VFP 5.0 indicate that neither loads it.

DDE uses some shared memory, if the older 16 bit apps disregard this, it might very well cause a GPF, especially in the DDEML.DLL. I would hope that VFP, being written by Microsoft, wouldn't disregard their own rules, but you never know. Let me know what happens with the test.
