I specifically "upgraded" to RH11 from 8 to resolve this issue. I have installed update 4 (11.04.291) and installed another patch from this location: WebHelp issues in RoboHelp versions 10 and 11
RH11 is installed on Windows Server 2003 R2. I am merging projects, a parent project and 2 child projects, using the redirect very helpfully supplied on Peter Grainge's website, and am adding the MOTW to resolve issues with customers using IE enhanced security and am manually changing the MOTW from <!-- saved from url=(0014)about:internet --> to <!-- saved from url=(0017)https://localhost --> (see previous post Navigation panes empty with Internet Explorer Enhanced Security enabled). I have also tried generating the WebHelp without the MOTW with the same results.
Despite having the latest version of RoboHelp with the latest patch (as far as I have been able to find on the Adobe website), the navigation panes are still empty in any version of Internet Explorer that I have (8, 10, and 11) , as well as Chrome. Is anyone else still experience this issue of empty navigation panes in WebHelp?
