When I make the same test, using Mozilla Firefox on Linux and Windows,
it  ends up at the same URL, but that IP,  is shown to be owned by
OpenDNS. But it works properly using Mozilla Firefox 3.0.13 on M$
Windows XP Home and it does not on Mozilla Firefox 3.0.12 on CentOS
5.3. I went into .mozilla and wiped out the contents of the cache
(which I don't think contains URLs) but that has no effect and I also
wiped out the catch using the dropdown menu in Firefox.
