Thank Chuck for your time...
It seems to happen only when the PDF is being sent as a download as
part of appendToResponse... Even in the Apple Example for File
Downloads there is a repeat so I modified what I was doing and just
created the PDF, wrote it to the file system and then offered a link
to the file for download.
Again thanks for your input.
