Ver. 2.3.0 (003) from 26 JUL 2019
Clicking the highlighted link http://dk0wcy.de/magnetogram in the "Propagation DK0WCY" window causes an error - the link does not exist.
It seems that the program calls a wrong link /usr/bin/http:/dk0wcy.de/magnetogram
Note the single slash in http:/dk0wcy
This option was OK in previous versions.
