I saw the post about "make online only" for Mac, but I'm on a PC and have the same issue. When I right click on a file, I do not see an option for make online only. I'm using a new PC and thought when I downloaded the dropbox app I said that I wanted online access only. Do I need to uninstall and re-install, or is there another fix? I had to pause syncing because I'm getting a "full" message.
