Hello John,

Thank you for the help.

I'm using the \X'link ...' shortcut, translated to the following
sequence by neatpdf:

12 0 obj
<<
  /Type /Annot
  /Subtype /Link
  /Rect [138.20 554.00 259.00 564.00]
  /A << /S /URI /URI (#1.0.3.0) >>
>>
endobj

Links starting with a "#" are considered as internal ones when using
neatpost. On pdfs produced by neatpdf, the link is recognized, but as
an external one. My pdf viewer tries to launch a browser rather than
pointing to the reference in the document.

I guess it's the anchoring system which is not working, but I did not
investigate more. For information, utmac is using the following
postscript sequence to insert the needed anchor:

\X"ps [ /Dest /1.0.3.0 /DEST pdfmark"

Warm regards,
Pierre-Jean.
