After upgrading to 5.1 on a mac running Catalina, I can no longer paste into the “biblatex source” field.
There is a similar issue in the bug tracker: https://github.com/JabRef/jabref/issues/6843
And there is a (temporary) solution to circumvent it.
I hope this help.
Thanks for the reply. I did install 5.2, but it doesn’t seem to help, unfortunately.
@Jonathan_Lilly I am a mac user myself and the latest 5.2 fixed it for me.
How do you paste? Using the shortcout cmd+v ?
Ok, I see. I can now paste over the whole entry if it is selected. So, that is a good enough workaround. However, I can’t place the cursor in the bibtex source window and paste in a particular location as I used to, nor select all text in the bibtex source and paste over it. And I’ve tried with both drop-down menu or command-V.
