yes, but you've moved your error down a level -- at least the OnQuit 
method is being called successfully.

I'm not familiar with the presenter code, but it looks like in this 
case, presenter may be a class object, rather than an instance object.

I'm guessing: presenter() ;-)

the trick is to store is somewhere -- globally in the module (probably 
not the best idea) in your app object, in the model object, etc.
