I too am having this problem. However, I don't get a message that Internet Explorer needs to close. When I close smaller windows, every window closes down to my Juno toolbar. Even my juno homepage shuts down. I am not kicked off the internet, just off of every open page!? Thought it was a problem with Juno, but NO! People PC had the same problem. Like others who've replied, it is only on MY computer, NOT my husbands Laptop. I am running Windows XP Home Edition Service Pack 2 with Internet Explorer 7.0. PLEASE CAN ANYONE HELP?
