I am using MATE Dock Applet v.80 (GTK2) on Ubuntu 16.04 LTS with the Mate desktop. It works fine, but some programs do not get listed in the applet. Mostly, portable apps are affected, but others as well.
Some example programs which do not show up are:
- LibreOffice Calc (was already pre-installed in my distribution)
- JabRef (used portably)
- NetBeans (used portably)
- Simplenote (used portably)
- Atom editor (used portably)
- Eclipse Java (used portably)
- Eclipse JavaEE (used portably)
- ...
What can I do to fix this issue?
