I was having sync troubles so to save hard drive space I went to App/Preferences/Manage and selected all to be online. According to the app “…saves hard drive space. Files will still appear on your computer…”. But now the list is empty, and I can't figure how to return them to offline.
Dropbox is not behaving according to your help files. All files sync but the online/offline/sync icons are not working, all files are either completely on my computer or not.
(Backup works ok, the files sync but are completely on my computer - but that's how Backup works.)
I have tried: Fresh install - restart - force quit in Activity Monitor - restarted Finder - no solution.
