New folder command dimmed
I am using OS X El Capitan
When I try to create a new folder in Finder window using the 'New Folder' item under 'File' in the toolbar at the top of the page, it is greyed out
I have used 'Get Info' and it shows I have read and write permission for the folder I am in
If I unlock the yellow padlock symbol it is still the same
Any ideas please?
