title: Dropbox file locking for shared Word documents
body: <p>I have a Word document shared with several other people in Dropbox.  If a Word document is on a shared drive, users are notified if it is already opened.  Since a local copy is opened in a Dropbox folder, multiple users can open and save the file ignorant of the other users state.  Is there a way to add another lock to the file so that when one person has it open, others are warned if they try to open it?  I am considering writing a VB macro that creates a token file.  It is simplistic and there are corner cases when working offline, but we need something to avoid or at least be alerted to conflicts.</p>
