>My question is this: is there something I can do to see what events have fired and which event handlers have been delegated to handle the event? I suspect something goes wrong in the wiring somewhere in there, and being able to track which events are actually firing might help me find where it's going wrong.

You ought to be able to call GetInvocationList to see a list of delegates for the event:

      Delegate[] delegates = 
         MyEvent.GetInvocationList();

I have never done this but you can read about it here: http://www.fawcette.com/vsm/2003_05/magazine/columns/qa/
