Turns out the main application class doesn't receive mouse events
(O'Reilly AS3 Cookbook recipe 1.6). Not sure why that is.
The problem in my game was that the localToGlobal call was incorrect.
If you mousedown on a Sprite the event target will be the sprite. If
you mousedown on a Shape, the target will be the parent.
I wrote it all up at blog.flexygen.com.
