Then this seems to be a Bug, because I have tried it with different documents, 
and sometimes on the TopDUContext the range is 0, and sometimes it is not. I 
have yet to find the common denominator. It is possible that it might be due 
to a local change, but I doubt it, since I have not changed any code related 
to text ranges.
