I agree that Core Data is helpful here. But it's not a panacea. For one, there doesn't seem to be a nice way to get the Undo menu item to say descriptive things like "Undo Typing", "Redo Size Change", etc. When doing things 'the hard way' that part's actually easier. -- ____________________________________________________________ Sean McBride, B.
