Doug,
My responses to your questions were not meant to be
sarcastic. If you've have perceived them to be then
I'm sorry about that. It's not my policy to make
sarcastic comments.
Please see my responses below:

The equivalent to the EventListener Object would look
like this:
el={}; // instantiate an event listener object
//assign a function to the event listener object
el.onscroll=function(e){
//whatever
};
scrollbar.addEventListsner(el); // add the event
With this change also comes the removal of the
DynEvent.getTarget() method (it was the only reason
for having an EventListener object). For events that
are created by the widget DynLayer itself, you can
replace instances of e.getTarget() with e.getSource.

It's best to use lower-case for event names. For
example:
blarg = {
onblarg : function(e){
some code;
},
doblarg : function(what){
some more code;
}
}
doblarg would be a function of the blarg object, but
if the blarg object was added to a DynObject using
addEventListener, only the onblarg would be triggered
when the invokeEvent("blarg") function is called.

I understand.
