iTunes 12 - old style Get Info using not working
I've become accustomed to using iTunes 12, but because I have for a number of years utilised most of the fields available in the older version Get Info screens (not available by default in iTunes 12) in order to create and manage smart playlists, I have been relying on retaining that access by using <Shift-Click> to bring them up. Alarmingly today I've attempted to access the old style Get Info screens only to discover that the <Shift-Click> option is seemingly not working!
As I hadn't heard of a change to this feature, nor can I find anything on the net about it, I am just wondering if anyone else is having this problem, and if so, does anyone know of a workaround? I keep my versions of iTunes up to date and recently downloaded the latest version (to 12.1.0.71), so perhaps a change was included in that update?
Without easy access to those fields I may as well give up iTunes and go fly a kite, so any advice will be gratefully received!
Cheers.
