Again what is the issue you are hitting... seeing retain/release sent
to an object while your application runs is to be expected. It is also
expected that NSNotification will retain the object related to the
notification and release that object once all listeners of that
notification have had a chance to process the notification.

Using ObjectAlloc you should be able to work out which retain is the
one that appears to be unbalanced if you are having an issue with your
window not going away... to me it sounds like some third party code
(or your own) is retaining your window and causing a retain cycle (for
example a view in a window shouldn't retain its window).
