I am migrating custom tools from Desktop to Pro. On the Desktop side I built fully functional help using CHM Editor and HTML Help Workshop (MS). On the Pro side I recreated the help editing the tool Metadata. It looks fine when viewing there. When I run the tool and click on the question mark, the displayed is distorted viewed as the contents of a file stored in the default MS user file: "file:///C:/Users/Tim.Leach/AppData/Local/Temp/...". Is there any documentation? Can this be fixed? Is this a bug? Is this being worked on?
