Hello,
I am working on the Debian packaging of jmol. We have got a bug report from an user using an xfce desktop. When he clicks on the weblinks
Help --> Jmol Wiki
Help --> About Jmol --> several weblinks
then nothing happens.
He met this issue with version 14.6.4, and I am able to reproduce it with version 14.30.2 with xfce (with Gnome everything is ok).
For a bit more information, you can see the page of the Debian bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=872418
Thanks for your help,
Pierre
