The above is what I see in the Word mailmerge fieldname. When I
manually open the text file it appears like this:
" name
"," address ", etc...

The only difference I can see between the problem fieldname and the
others is the length.
If I take a valid field in the ASCII text file and add spaces to it, so
that the total field length is over 39, then the same thing happens to
it.
I've tried Unicode format as well, same problem.

Am I missing something here?
