AS2 ... how to NOT capture an event, how to pass the event onwards through the event bubbling flow

Question

hello;
I have:
Class my_class
  { public function my_class( an_mc )
         an_mc.onUnload = function()
           { // this capture prevents other listeners from getting it also;
             //  in Adobe Director's Lingo, there is a pass method.

Answer 1

true;
I have two requests for some_mc.onUnload, one of which is built into a flipbook 'component' that I am using, and the other one which I need;
it seems that mine is preventing the flipbook component from receiving it's;
so ideally I would like to 'pass' the event onwards to any other listeners ( ie the flipbook's );
for now I am not including mine in order to allow the flipbbook to do what it needs, and using some hacky approach to realise that some_mc has been removed from the stage;
