Following the recent posts about this tool I thought that I would give it a try, thinking that it might produce a more logical listing (i.e. making the Home Person no. 1). It didn't.
However all of my places, events etc have lost their References - that is the Reference Tab for all objects are now empty. Fortunately I made a backup before running the tool - this could have been a big loss on a database of 4000 persons.
