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.
