I work from home and have several different windows accounts on my PC. Most are personal and only one is used for work. I want Dropbox to open automatically when I log into my work account but not when I log into other accounts. So far it seems I can have it open automatically for none or all. My work around is to add it to the taskbar so I can open it with one click, but can it open automatically for selected accounts (one in my case) but not for others.
