It really sounds like you have a zombie somewhere. Or you didn't unregister a KVO observer before it was deallocated. If you deallocate an *observed* object before unregistering observers, KVO will bark at you. If you deallocate the *observer*, KVO doesn't warn you. --Kyle Sluder_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
