DragProxy Error

I have an AIR application using s:Window component and I'm dragging between
it and the main window and it works 95% of the time, but then I'll get the
following error. I've not been able to successfully figure out where to
place a try/catch so the application doesn't crash. Any suggestions? I did
read the thread about DragProxy arrow and drag image showing up in the
parent window but that doesn't seem like the same thing.

TypeError: Error #1009: Cannot access a property or method of a null object
reference.

I now see that it's throwing the error in this script as the event is null

		private function effectEndHandler(event:EffectEvent):void
		{
			DragManager.endDrag();
		}

If there's no easy fix from the app, can someone point me to a tutorial so I
can recompile the SDK for my app and at least catch that error?

Thanks much.
