I am having the exact same symptoms under FC7 with the stock httrack RPM,
installed using "yum install httrack".  It flat DOES NOT WORK.  Just says it's
mirroring with help from the wizard, and hangs.

When I hit enter, it reports having received the full length of the file, but
it does not appear to move on and get another.

I can wget these same pages fine, and view them in links, so I know this is an
issue with httrack (which works perfectly on my Ubuntu 8.04 box).

Arrrgghh!  Such a good program to have what appears to be such a simple issue
preventing me from being able to use it!
