SYMPTOMS
Methods that are invoked as late-bound object references go through the IDispatch::Invoke method. Therefore, the dispatch method names are hidden. The COM+ eventing mechanism accurately reports IDispatch::Invoke as the called method. It is frequently impossible to distinguish which dispatch method was invoked on such an object. Dispatch method names may be reported instead of IDispatch::Invoke.
