I guess they must've fixed that, since I'm using Windows XP in a small network in the apartment building that I'm in and my nephew sometimes logs in to the internet on my system, using his user profile, and my connections stay just fine. I run Trillian and 4 IRC bots 24/7, so if there was a problem with the connection to the internet when he logged on with his profile, I would've noticed it next time I went to switch users to my account.
