Dropbox and login items list I have Dropbox installed on my Mac with OS X Lion 10.8.2. I don't use it often, so I eliminated it from the login item list. However, every time I open Dropbox from the application folder, it automatically add itself to the login item list. Is that normal, even if I locked changes? Can I prevent Dropbox to add itself to my item list every time I open it?
Under Dropbox preferences, there is a checkbox for "Start Dropbox on System Startup".  

However, as patrix says, Dropbox is really only useful if you leave it running all the time.
