To backtrack sightly, the specific exception you are getting is being thrown by an NSArray because some other object is calling addObserver:forKeyPath: on it. In the debugger you can verify which array it is, and you should also be able to narrow down which object is calling addObserver:forKeyPath:, or at least for whom it is being called. I can't recommend further until we know what those are... HTH, Keary Suska Esoteritech, Inc.
