Hi jdorin,
It wasn't me who suggested the registry change; it's also not a change I'd be inclined to suggest as it affects all mailmerge documents and can result in your data source being unwittingly tied up and preventing update access by other users. Whatever the change was (presumably one of those outlined at
http://support.microsoft.com/kb/825765), it would entail modifying the equivalent keys on the other platforms - note that it's different for every Word version!
My approach would be to use a macro that keeps your mailmerge main document as an ordinary document and runs the SQL query from the code. For such an implementation, see:
http://answers.microsoft.com/en-us/o...0-91114d2c896e. If you store the document in a 'trusted location', it won't generate the macro warning, either.
