This has happened a couple of times now, and I use Vista. I'll be connected, using the internet, and then suddenly, my Internet Explorer will just stop working. My Instant messaging programs will still work, like Yahoo Messenger, and Myspace Messenger, but I won't be able to connect to any websites via Internet Explorer. My Vonage phone works just fine, also, so I know I am still connected. A few times it's just fixed itself when I tried using my computer a few days later, but this keeps happening and it's not fun. I guess I need to know what's happening so I can fix it/prevent it. I'm not a techie by any means, so any explanations in layman's terms would be appreciated!
