[tex-eplain] hypertext problems

[John Frampton]

If I Tex the following file:
---------------------------------------------------------------
\input eplain
\beginpackages
\usepackage{color}
\usepackage{url}
\endpackages
\enablehyperlinks

(1) Click on
\href{http://www.math.neu.edu/undergrad/mthu130}{menu}
to see a menu.

(2) Click on
\url{http://www.math.neu.edu/undergrad/mthu130}
to see a menu.

(3) Click on \hlstart{url}{}%
{http://www.math.neu.edu/undergrad/mthu130}menu \hlend
to see a menu.

\bye
---------------------------------------------------------------
, then apply dvips (with the -z) option, then ps2pdf, a pdf file
is produced.  For (1), /table/ appears colored, but is not a
link.  (2) works as expected.  Clicking the link goes to the
desired url.  (3) produces a link with "menu " appended to the
url.  (1) is the form that I need.

I have no idea what is going on.  Any help would be appreciated.
Because I use PSTricks heavily, using dvipdfm or pdftex is not a
viable option.

Thanks,
John Frampton
