I have a funny problem with Internet Explorer 8 where I set up a proxy server under Tools - Internet Options - Connections - LAN Settings - Proxy Server and IE basically ignores it.
For example, if I set up the proxy server to use (Random IP here) 245.245.245.245:80 and then go to a website such as whatismyip.com, it still shows my ip instead of the ip of the proxy.
To add further confusion, this only happens sometimes(!!)
Any ideas appreciated Regards Adam
