It costs a little but once you look at the footnote/text style "language" used for win and win95 help products like RoboHelp from Blue-Sky become very appealing. They create a 'project' environment with tons of word macros for word6 (16bit help) and word7 (32bit help) and support a smarthelp ole control that works with Visual Fox3 and 5. There are others out there but we've been pleased with this one. Also has a easy way to use the SHED editor to put 'hot spots' on graphics to trigger help popups. Nice gingerbread for apps.
