I have a broadband cable connection. Eventually I do get the message when I refresh several times. Similar phenomena on other sites.
Some sites seem to be invulnerable.
It happened with IE 5.5, IE 5.1 and also Netscape 4.7. But that same cable connected to my laptop using W98SE and IE 5.0 did not have a problem. This is very annoying and reduces considerably my surfing pleasure.
