Ahh, good point, exactly (and wow and having no hint of sarcasm as that is blindingly obvious now). Dropbox has this behaviour by default, yes. MacBook Air owners with piddling hard discs (me) may use it as a cloud only store by messing around in prefs, and then forget that it ever worked any other way. I know this misses the main attraction of Dropbox, but one day Ill have a decent disc and will restore it to its former glory.
