Photoshop CC 2017 'Use legacy "New Document" interface'
Photoshop CC 2017, 2017.0.0 Release, 20161012.r.53 x64
Hi All,
I would like to try the new Start Workspace but my Preferences/General Options –– legacy "New Document" interface
is greyed out. It's like it's locked closed. I've tried fiddling with other boxes in Options to try to release the option,
restarting both application and computer but nothing works so far.

Any helpful suggestions are welcome
Sincerely
John Eley
