Thanks Tim. If PumpWaitingMessages is queued AND messages can only occur when PumpWaitingMessages is called, then Questions 2 and 3 are resolved since absent the call to PumpWaitingMessages events can not occur.
I am still a bit concerned, however, because of an experiment I ran several days ago, see "DispatchWithEvents experiment with subclass eventroutine and pump messages" from 6/5. In this experiment there were NO calls to PumpWaitingMessages yet events/messages DID occur! How sure are you? FWIW, memory serves that the OnVisible event is unique and doesn't have to be pumped. I do not remember where I read this or why it is so. Such, however, is NOT the case with OnDocumentComplete. So I'm still a bit uncertain. Do you know of any hard test to verify the behavior?
