Hi,
just a short reply now as a sign that I haven't ignored your mail.

Yes, that would probably be helpful. However, I can't think of an easy and
fast fix for all instances right now, because in particular the viewer is
started as a child process (at least if texdoctk runs in quiet mode); see
the following bit in the sub viewslc:
} else { # viewer messages written to /dev/null instead of terminal
if ($browser == 0) { # normal viewers or new Netscape/Mozilla
system("perl -we 'use strict; \
my \$dump=\"\"; \
open(NULL,\">/dev/null\"); \
open (VIEWQ,\"$viewer $slcdoc |\"); \
while (\$dump=<VIEWQ>) { print NULL \$dump; } \
close(VIEWQ); \
close(NULL);' &");
} else { # open doc in existing window (Netscape or Mozilla)
That makes it difficult to capture error messages from the child for use
in the parent (at least so it seems to me after a first look). In some
other instances, I think one can deal more easily with this issue.
When I find some time, I will try and concoct a solution, but I can't
promise that I come up with something soon. If you have an idea, feel
free to tell me.

If it's the dlc.ku.dk one, yes - my former host instution has ceased to
exist. In the most recent release (0.6.2) which I sent to Thomas Esser
some months ago, my current address is given.
Regards,
Thomas
