Jabref: Groups Panel closes when selecting different database

[Braunch]

JabRef version JabRef build from master 21.07.2016 on Ubuntu 14.04 and on Windows 8

Steps to reproduce:

When I...

1. Have two databases opened
2. I open the groups panel in the first one
3. I switch to the second db and open the groups panel too
4. I switch back to the first one (groups panel is still opened)
5. I switch to the second db
   ...then the groups panel closes without being manually closed by me.

Have you checked the groups preferences? There may be some combinations there which causes the problem.

I just saw that this is an option you can set in the preferences:

So not really a bug, only a questionable option IMHO.

I would simplify this by removing these two options and either the group window is shown, or it isn't, depending on the group toggle status.
