Hi Gergely,
The screen shot is from a clean install of the latest Google Chrome.
Using "Set Program Access and Defaults" I clicked on the Firefox as my default browser. Started archicad and when I go to the
AC Help
Google Chrome opens up.
Still Empty
the other Help menu items in Archicad help open up in Firefox, always did, it is just the AC Help that opens up Google Chrome.
I can manually right click on the AC Help w here archicad is installed and choose Open with, and get it to open in firefox, but within AC it still opens with Google Chrome.
Sigh.
