You know, now that I think about it, I'm wondering if I may have set parental controls on the user account. I've also got it installed on a PC at work -- for testing -- and it works flawlessly. I can access any site I want and I get propmpted for updates as they come across the wire. That's the only thing I can think of. If that's not the case next time I look at her PC, I'll prolly wind up pulling it off and installing something else.
Anti-spyware is something I'm pretty big on too. I don't want to have to make 16 trips a day because a host of spyware bugs keep changing the hosts file.
