total nonprogrammer here
I started with backstreet browser, which has an explicit option for auto
update of a downloaded site: you have to tell the program if you want it to
download a site, and store it unchanged, or download a site and update it as
the original changes.
Is this behaviour in HTTrack and if so, how do i control it

by the way, backstreet didn't work for me, so i went to this program, which is
working much better.
