Thanks. But I tried and still failed. I'm not sure whether it's because I can't
change explorer's proxy setting, or HTTrack does not render correctly the
proxy address from my vista home prem (I have a router and anti-virus
software; I don't know if these complicate things either).

HTTrack gives me this proxy address:
fe80::c062:e8dd:8e5c:f9d%11

Is this a valid one -- looks neither like a URL nor a X.X.X.X?
After I copied that address to explorer, and login, nothing happens
(presumably HTTrack will tell me that it has captured the url). I opened
explorer's proxy setting again, found it empty -- I guess either explorer does
not recognize the address, or there are some other tricks that prevent me from
inputting the proxy address. Any suggestions?
Thanks in advance again.
