I seemed to have found what is causing the problem here. I had an NSTabView's selectedIdentifier binding bound to File's Owner.window.toolbar.selectedItemIdentifier Apparently this would cause a problem because it would call the window controller's -window method again, which would call -loadWindow again, and then proceed with all that nib loading business until it tried to make that same connection at which point it would all start over again. This used to work just fine and I thought this was the standard way of connecting NSToolbars with NSTabViews. Must I connect this binding programmatically after the window loads?
