Does the VB6 code declare the managed type instance using the WithEvents
keyword?
If that's not it, a shot in the dark -- is it possible that [ComVisible(false)]
on the declaration of SimpleTarget makes VB6 avoid the SimpleEvent event
because it somehow can't see the declared type of the event? (It should be
getting it from the ISimpleSource declaration, but who knows...)
Good luck...
