Every time I turn off dropbox app and restart, all my files sync back to my computer as local files. They do not stay as "online only." I have played with all the preferences, but am I missing something? I now have 6,000 files constantly coming back onto my computer as "local" and then i have to go in and manually sync them back. Then, when I upload something and want to make it "online only" to get it off my computer, it doesn't allow me to make them "online only"
