Re: [basic] retain an NSTextView object and update a window

The second time, you're probably calling those methods on some other
instance of aWindowController.  The object you created in Interface
Builder, represented by that blue cube, is one instance of it, and it
is the one with a connection to the NSTextView.  If you want other
objects to use that same instance of aWindowController, you'll have to
connect them in IB using an IBOutlet in the other objects..

You generally don't need to retain any user interface elements, other
than windows that will never be used again once closed.  .
