That did the trick for undo/redo!  Thanks!

Yes, using:

   [NSBundle loadNibNamed:@"InvoiceEditWindow" owner:document];

I also tried a specific:

   [document addWindowController:invoiceEditWC];

and I further tried setting the 'Document Edited' binding for the 
window to the document's isDocumentEdited accessor,

all of these with no success.
