Igor, In earlier versions, it was possible to delete the comment line - and it would stay deleted and no comments would be added to the slide in the show. This ceased to function correctly in version 3.80 - although it could be deleted, once saved, the comments keep on reappearing. Perhaps you could have a quick look at this area and see if it is possible to fix it please. Carrying on with this line of thought, would it be possible to have an option in the customise slide dialog box so that the comment could be set to 'on' or 'off' there, since there is already a tabbed header for the comments.
