Resolution is hidden within the "Build" option under (wrong!) description "no
external pages".
IMO, definitelly a proper descripion should be "no external links" - and that
is the (proper) descripion in HELP, if you look here.
The same refers to translation of course.

IMHO, this can be a sensible information in FAQ - HTTrack is suposed make copy
for *offline* reading, I am right? (and copy with active external link is
not).
