Problem solved. I can make it work like the documentation by
subclassing window and doing my own dispatching for mouse entered,
exited, and mouse moved. I can use hitTest to determine the view that
should receive the events, or always direct them to the view I want to
receive them. Since the window only gets the events if the responder
chain of views does not want it, any view can capture the events
keeping the existing behavior intact for existing code.

I agree - and have run into the same problems. If you hit on a
solution please let me know. I dont think tracking rectangles are the
answer. There are things you might want to track that arent
rectangular. Also there was some posts on this list recently that
having large amounts of tracking rectangles (look up "Tooltips - what
a pathetic joke..." on http://cocoa.mamasam.com/) greatly slowed down
scrolling.
Of course you could have a repeating task for each view that gets the
current mouse location and does its own tracking. But that doesnt
seem very friendly.
The problem with using mouseMoved events in this way - is that they
fire even if the mouse movement took place outside the view. So if
you had many views - all receiving mouseMoved events - it could
overwhelm the event queue. Id like a MouseMovedInView event that only
went to the one view the mouse moved in - even if that view isnt the
first responder.
