hello, I run into the following problem under Windows 7, Gretl 2016d, build date 2016-11-19: of all the PDF documentation listed in the Help menu I can access only the "User's guide". Clicking on all the others opens a box with the "no entry" roadsign (white band on red background) and the warning "cURL error 60 (Peer certificate cannot be authenticated with given CA certificates)"
bye and thanks
Stefano
