Dropbox update

I contacted Dropbox customer service and they gave me instructions on how to better sync saved documents on my MacBook and on my iPod.  They said I had two accounts and then suggested to disengage the iPod from Dropbox and then log back in.  I have done that and it does reload things so they are updated and synced.  But only for the moment.  This solution is not satisfying.  Syncing over the internet should happen seamlessly.  I should not have to log out and log back into my account on my iPod in order to get things to come over updated.  This just isn't making sense.  I will need to do work in this area.  As for now, Dropbox is under delivering.
