In what cases would the last argument not be 'this'?

Yes, it calls all delegates, but does not check the event type for which
they are registered.

I'm also not sure if that modification would help during this situation:

  button.Clicked = new EventHandler(OnClicked1);
  EVT_BUTTON(-1, new EventHandler(OnClicked2));

Since the array of listeners are completely separate, the event would be
handled by the last handler only.  So in this case, even with he event
type checked, it would not work.

I think that there may need to be a static hash of listeners, and that
MarshalEvent needs to be passed an event type.  The listeners could then
be indexed by the event type, and looked up based on the event ID. 
(Writing something to do this now....).

Either that, or I'm completely missing the point of your code :-)
