Thanks for pointing me in the right direction on this. Now if I could only sort out the undo menu enabling issue....
Are you using setPrimitiveValue:forKey: without wrapping it in willChange/didChange invocations? If so, you will get neither undo registration nor KVO notifications for those changes. The undo menu won't be enabled if there's nothing on the undo stack, so this could explain the behavior you're seeing.
