I spoke to the guy while i was at work about this.... it seems to be a problem with the browser on the machine, or something that has been cached there.
Goldoni, have you tried using a different browser on the pc that it is having problems? try downloading mozilla firefox (
www.mozilla.org) and see if you get the same problems.
Just for the benefit of others here we have ruled out:
1. proxy servers
2. caching on local machine
3. problems with the site design
4. dns issues
5. spyware/ malware
and i have now run out of ideas....
