A friend just bought a new Dell Box - with Vista -and has developed a problem: Email follows

"I have a problem and you may be able to help me out....I bought a new computer, got a Dell. However, in the last day or so I must have hit a wrong button because everything I want to look at comes up "Navigation to webpage was canceled". I am lost. Do you have any idea how I can turn this around. "

I Googled the "Nav to web page cancelled" and found a couple of occurrances, but no solutions

I got the idea from Google that maybe something had hijacked something in the "Host" file

Any help will be appreciated - it will be this week end before I can get on her computer, but maybe someone has some ideas as to where to start - OBTW - I have not messed with Vista at all, so any instructions should take that into account
