... Use the attached version and also perform a core update of jAlbum. It now plays solid here.
I did that. But before
the core update the version is 20.3b1.
I think David has fumbled the version numbering. Reinstall the regular release of jAlbum 20.2. Then do Tools > External tools > jAlbum core update
. Don't do the Beta
core update. You should end up with 20.2.6.
