It was me that pointed out the fullscreen problems to mmalc. :) An NSView has no control over whether its caller will decide to make it fullscreen or not, so the viewWillMoveToSuperview solution isn't ideal. >http://homepage.mac.com/mmalc/CocoaExamples/controllers.html#unbinding > >As for whether it's thread safe, I would say no, because Cocoa >Bindings in general is not thread safe. See Chris Hanson's post on >the topic: http://chanson.livejournal.com/2005/07/23/ I'm inclined to agree. However, mmalc's page says "If your view may become full screen, then you should ideally use another invalidation method to mark when the view is finished with and unbind in that, otherwise you should unbind in finalize". So if not finalize and not viewWillMoveToSuperview, when can I stop the observing I started in bind:? That's what I'm trying to get at really.
