I've seen numerous articles instructing people to click on Dropbox on your taskbar, select preferences and click Manage in Backups. There is no Manage option in Backup. I've tried to click on "Automatically Back Up ..." "Set up" But it won't allow me to uncheck all the boxes and save these changes. The Set Up button on that page greys out and I can't click on it. Whenever I press the Set Up button again all the files are ticked once more so I can never be sure Dropbox isn't going to sync.
All of this is coming up because Dropbox keeps trying to backup my iPhone everytime i plug it into my PC. This is even after I set it to "Don't Import". Even after turning off Dropbox manually it automatically starts back up and does it again, like a virus. I am at the point of uninstalling dropbox.
