It should be, but you would need to be careful - eg, if your event handler relied on an object that was initialized *after* you call the method. But best I can tell, this isn't a COM or Windows question at all, and is just asking how Python behaves with respect to multiple inheritance? > Question 2: If the user_event_class overrides a disp_class > method how does > one reference the disp_class method.

I'm really not sure - we create the COM object with the name you specify, then ask that COM object exactly what it is, then match that info with the gencache. ie, it is under the control of the object, not us.
