Hi Tobias,
Thank you so much for testing. My guess is that the difference is likely due to
the way SWORD is compiled-- which dependencies SWORD is using. My speculation
is that libcurl is probably available on Linux and your Windows build probably
isn't using this library.
Can you let me know if SWORD is compiled with libcurl on your Windows build? I
will try to test a Linux build without libcurl. I tried to make the new feature
fallback to previous behavior if it couldn't use the new feature successfully.
I obviously have failed in my backward compatibility effort. 😊 I will try to
get it right.
