the screen was frozen. No hovering made any difference. All I was trying to do was synchronize.
I DID go to the two affected music groups; their YEAR in the album was "0000", I changed it to 1970, in whole albums, and that worked.
BUT, PLAYLISTS are still not sync'ing; I have 10 playlists; I re-sync'ed; and it has been sitting for FIVE MINUTES on the one playlist, with no progress, stuck at 87 %.
I can manually export the playlists, but this is discouraging, that the playlists themselves won't sync. (or at least won't sync for me)
ADDDENDUM - I switched the playlist format from the default of PLA, to an "M3U" file.
Re-sync'ed, and IT WORKED !!!!
that is good, I will see how it all works on the phone
