Thank you very much for responding--I am sorry to say that it was my own stupidity. I was simply forgetting to re-register on undo/redo. I was thrown by NSUndoManager presuming there is a redo even though there wasn't one registered, though I can't blame the API for this problem--as much as I want to ;-)
Thanks,
