Hey Ken, When you changed it to Content-Disposition = attachment, did you keep the content-type still set to text/plain ? You might try setting content-type to one (or maybe all) of these: Content-Type = application/octet-stream Content-Type = application/force-download Content-Type = application/download Also, you can try setting Content-Transfer-Encoding to "binary". best,chris.
