Victor,

With all due respect, there is a KB article that says the following:

"The problem with this design is that the Visual FoxPro ODBC driver is not thread-safe, and as a result, MTS/COM+ (or the objects themselves if they are stand-alone) can fail."

See: http://support.microsoft.com/kb/288863

I've seen your KB and I can't believe what it says. I think there's a lot of confusion going on around the VFP ODBC driver. When I was at MS I tested the VFP ODBC driver and found that it was not thread-safe. And I think by design it was not thread-safe.
