Word doesn't find double paragraph marks

[RobBroekhuis]

Another one I can't explain. I'm going around deleting double paragraph marks (i.e., empty lines). The following code does the trick:

     Do
        erng.StartOf wdStory
        erng.Find.Execute "^p^p"
        If erng.Find.found Then 
           erng.Collapse
           erng.Delete wdCharacter
        End If  
     Loop While erng.Find.found

It's written like this rather than a straight find/replace because some of other problem with the replace method that I don't recall now. Anyway, this works like a charm. But I have one document in which for some reason one pesky double paragraph mark is not FOUND by Word. Nothing odd going on in the document at that point (no page breaks, fields, or anything, just straight text). I can't for the life of me figure out what is particular about that situation. Anybody have any words of wisdom?
Thanks
