When I open the help in a program, left pane are the topics, but right pane no info. On a win10 pc there is no problem. Everything is the same (admin rights, same dir in c:\). Worth to mention is that when I copy the .chm files to the desktop, they function normal. But from within the program (context sensitive) no luck. Another strange thing is that after pressing 'help' win10 asks if I really want to open that program (I guess win program hh.exe). Someone plz? Grz. Paul
