first of all: Thanks a lot for this great software. I used JabRef to manage my books during time at university. I now started to manage my own books with it. Its great fun to work with it.
This is my problem:
I installed JabRef 3.4 on my new PC and imported the Bib File of my old Notebook which I allready thrown away. My problem is that with JabRef 3.4 and also after the update to 3.8 i can not Manage my Keywords anymore. I can ad or change Keywords in the Content selector window ui, but when I press apply or OK the changes are lost and not saved to the database.
Any ideas how I can fix this?
