It seems to me like that's circular.  Since the object calling
OnCancel() is a CComUI object, wouldn't the virtual call really be
regressive?

That was at the heart of my question:  the direction of the
inheritance tree searched when a call is made to a virtual function.  I
had it wrong apparently - the real direction of search is to start at
the child and go to the parents, then to the grandparents, then to the
great grand parents, then to the great-great grandparents, etc. ad
nauseum.
