Creating Help Screen/Files for Navision

I’m looking for a copy of HlpScrNavision - an addon for HelpScribble, a help authoring tool. John Tegelaar of DuoLink created the HlpScrNavision. Apparently DuoLink is no longer in business and I have not been able to contact him directly. Your assistance appreciated. Bill Malcolm bmalcolm@adnm-grp.com
