Cover Art In Tag Panel

I have a brand new PC and am migrating all my apps onto the new PC. I have installed MP3tag v2.96 on my new PC but it is not working as MP3tag used to on my old PC.
I seem to recall I could select a number of MP3 tracks and update them all to the same genre, year, etc via the Tag Panel and that included the Cover Art picture. In particular I could paste the Cover Art into all the tracks.
I can't paste a picture into the Cover Art any more. The paste is greyed out. It is a bind to keep using Alt+T to update the art in addition to using the Tag Panel for everything else.
Am I missing something like a setting somewhere? Thanks.

Try the latest beta, the issue is fixed.

Please try 2.96b.
