Many thanks for your suggestions.

Tried www.httrack.com.  FTP unchecked.  All other options unchanged. Do not
use remote access.  Get following errors.
- Warning:  Cache: damaged cache, trying to repair
- Warning:  Cache: 0 bytes successfully recovered in 0 entries
- Warning:  Cache: error trying to open the cache
- Error:  "Unable to get server's address: Unknown error" (-5) after 2 retries
at link www.httrack.com/robots.txt (from primary/primary)
- Error:  "Unable to get server's address: Unknown error" (-5) after 2 retries

IE7 accesses the website with no problems (hence I am able to reply to your
answer).

(1) What is meant by a "mirror"?(2) You say "check the firewall/antivirus
permissions".  What am I looking for when I check them? Port numbers, or
what?
Thanks, Anthony
