Based on your tip (thanks!) I looked at the online doc for
MainDocumentType, which says this:

"If you set this property for a document that's already a main document,
the attached data source is removed."

It doesn't specify what to set it to. Since my code already sets it to
wdFormLetters after opening, I verified that this really removes the
data source, plus it also removes the header source.

Try setting .MainDocumentType to wdNotAMergeDocument (of course you
lose all the data source connection info. but it looks as if you are
doing that anyway).
