I have two desktops and a notebook connected to Dropbox. One desktop and and notebook connect consistently and is kept up to date on what ever is happening on the other. One desktop has connected in the past but is no longer doing so. Although I have it 'on' in startup, it doesn't start on startup. No Dropbox icon appears in the taskbar and the files are not updated in the desktop folders although they are present and correct online. I'd be grateful if someone could tell me, in easy to understand language, how I can ensure that my inconsistent device connects all the time.
Best wishes
Brian
