I should have added that VFP COM components cannot play in the COM+ pool because they of their apartment model multithreading.


Quoted from "Requirements for Pooling" in "Object Pooling" in Jan 2000 MSDN:

"No thread affinity
Poolable objects cannot be bound to a particular thread, otherwise performance could suffer. For this reason, poolable objects cannot be marked Apartment model; they must run in the Multi-Threaded Apartment or the Neutral Apartment. In addition, poolable objects should not use thread local storage (TLS), nor should they aggregate the Free-Threaded Marshaller (FTM)....."
