PB 2017 R3 1858 Windows 10/64b
I refer to the local help browser triggered by F1 from Powerbuilder classic IDE.
When clicking on hyperlinks on topics new to this version of PB, I get the error message:
"Cannot connect to this page
check if the web address //ieframe.dll/dnserrordiagoff.htm# is correct"
(translated from my native language).
Hyperlinks to topics of long-standing history works well.
PB was installed to a fresh computer without any traces of older versions.
