I've been reading further on this. MTS does not bubble up the error like DCOM does. MTS returns a generic error. To get the specific error, you need to return it in your object or provide someway of getting it. I'm not sure that setting a property is the best way. However, just as with any VFP application, the error should be logged someplace.
