Whenever one hyperlink is nested inside > another, the entire remainder of the line is shown > as an hyperlink. > > If you are wondering why on earth would someone want > to have nested hyperlinks, please take a look at this > sample document I created; it also displays the "feature": > http://www.dse.nl/~dario/misc/nestedlinks.pdf [50KB] I consider this as bug in pdfTeX and have generated a small test file (plain format): \showboxbreadth=\maxdimen \showboxdepth=\maxdimen [part before] \pdfstartlink goto name{Hello} [hello start \pdfstartlink attr{/C[1 0 0]} goto name{World} [inside world]% \pdfendlink\space stop]% \pdfendlink\space [part after]\par \showlists \vfill\eject \pdfdest name{Hello}XYZ\relax Hello \vfill\eject \pdfdest name{World}XYZ\relax World \end Three annotations are generated by pdfTeX 1.30.4: 7 0 obj << /Type /Annot /Rect [148.989 757.436 540 767.399] /Subtype /Link /A << /S /GoTo /D (Hello) >> >> endobj 8 0 obj << /Type /Annot /C[1 0 0] /Rect [199.439 757.436 257.361 767.399] /Subtype /Link /A << /S /GoTo /D (World) >> >> endobj 9 0 obj << /Type /Annot /Rect [257.361 757.436 281.769 767.399] /Subtype /Link /A << /S /GoTo /D (Hello) >> >> endobj Either there should be two overlapping annotations or three distinct ones. At any case "540" in the first rect is too large. As workaround, the outer/enclosing annotation can put into a box (\hbox in plain TeX, \mbox in LaTeX). But it does not solve the problem, because now the link cannot be broken across lines. Therefore the algorithm for annotations needs to be reviewed and corrected.
