For example, the could restrict the UNDO mechanism to cells that are not generated (i.e. not output), and possibly the undo stack would only go back as far as the previous evaluation. I would have thought a multi-level undo is pretty vital in an interactive program! David Bailey http://www.dbaileyconsultancy.co.uk
