Do you have the folder set to show icons? I just tried it with a folder of my photos set to 'list' and, sure enough, auto arrange is greyed out. I changed to 'icons' and auto arrange is back ready to take the tick out.
it works fine for me in Photos,Videos,and Music, as long as they're set to show as icons.
It doesn't work in Documents.......but I don't want it to work in there!
