Hello masters Allin and Jack (and Sven, and Henrique, and ...).
On my Fedora 28 Linux,
First I got an error with Firefox and it did not start the browser:
Second, with Google-Chrome it opened the site, but a lot of output (specific of my system related with fonts):
(...) Removed a lot of messages from Chrome
gretl_clipboard_set: fmt=1, imgtype=0, n_targs=4
gretl_clipboard_get: info = 0 (TARGET_UTF8_STRING)
gretl_clipboard_get: info = 0 (TARGET_UTF8_STRING)
Since I use KDE, I also experimented Konqueror, but similarly with Friefox it did not launched the browser:
This is not problematic, but I'd like for you to test on different systems.
Thanks.
