Re: event/notification for focus?

Basically there's a text field, check boxes, radio buttons and buttons.
Like I said, makeFirstResponder is called every time I tab through the
controls but the notification is only received once, when the window
has closed.

You sure [self window] is returning a window reference and not nil?

Also is the window returned the active window (not sure without digging
in docs if firstResponder is expected return no nil for deactivated
windows, etc.)

What is self here, what class of object?

Actually that code is no good anymore...
