We need to clarify what is happening in a VFP MT-DLL. It isn't multi-threading in the normal sense. It is really apartment model threading. You aren't going to spawn multiple threads and allow a single instance of the DLL to simultaneously run more than one thread for the same instance of an application.

And yes, you need to run the DLL under MTS or Component Services in Win2K.

You should take a look at the Readme and help files that ship with SP3. They contain lots of information that will helpe you.
