Basically there's a text field, check boxes, radio buttons and

through the controls but the notification is only received once,
when the window has closed.
How did you subscribe to the notification? Did you try using the
delegate pathway?
>From the code I see I don't see why you would be getting the
behavior you described.
Are you running any type of run loop of your own while this window is
up?
Is it a modal window of some type?

here's how I register:
NSNotificationCenter* center = [NSNotificationCenter defaultCenter];
[center addObserver:self
selector:@selector(windowDidMakeFirstResponder:)
name:@"WindowDidMakeFirstResponder" object:nil];
Is the window you are working with a modal window... application modal,
document modal (sheet), etc.?
My guess would be that you either have a sub-runloop in place or the
main runloop is in a particular mode while the window is being
displayed that is preventing delivery of the notification.
As a test you could modify the NSWindow subclass to change the modes
that the event should be delivered under.
Replace...
[[NSNotificationQueue defaultQueue] enqueueNotification:notif
postingStyle:NSPostASAP];
...with something like the following (consider adding
NSEventTrackingRunLoopMode as well if needed)...
NSNotificationQueue dq = [NSNotificationQueue defaultQueue]
[dq enqueueNotification:notif
postingStyle:NSPostASAP
coalesceMask:NSNotificationCoalescingOnName |
NSNotificationCoalescingOnSender
forModes:[NSArray arrayWithObjects:NSDefaultRunLoopMode,
NSModalPanelRunLoopMode, nil]];
