>>I think much of the scalablility with VFP COM comes from running it in MTS. Did you use the new Session class for you classes? You should. Is the VFP Runtime properly installed? By this, I mean, don't just copy over the DLLs, but installed using setup procedures.

This could be a problem. Custom classes use the default data session and, according to SP3 help, (if I read it correctly) could cause people to see and modify each other's data.

Actually, you should apply SP3 to the development version and then create a setup with the runtime files. Make sure you have VFP6T.DLL, as it is the Multi-threaded runtime.
