I am running on Win XP Pro SP2 with IE6 SP2. Upon accessing Hotmail or Yahoo mail, I keep getting this message. Browser Not Supported Microsoft® .NET Passport no longer supports the Web browser version you are using. Please upgrade to a current Web browser, such as Microsoft Internet Explorer version 4.0 or later, or Netscape Navigator version 4.08 or later. The Yahoo one says Yahoo! may not be optimised for the web browser you are using. Your options are: Upgrade to Internet Explorer 6.0, Netscape 7.1, or Safari 1.2. Switch back to the Yahoo! version supported by your current browser. I am at a loss how to correct this, it has worked once or twice then this. any help would be appreciated.
