I tried to update the capture of www.alistapart.com with 
version 3.23-beta-7. It only returned 280 error 404 pages.
I tried a new capture, same problem.
I unticked the option keep alive but had the same result.
Version HTTrack3.22-noV6 mirrors the site without any error 
404 pages or message.
Is there any good reason?Regards
