I have just used the Wubi installer to install Ubuntu onto Windows Vista. I have plenty of space for it. I have used this installer on another machine and never had an issue. However when I try to log in for the first time, I see the UBUNTU logo with the dots under it, then I briefly see the form for logging in where I would enter user name and password. But then that form disappears and I just get a purple screen. I only see it for about 5-10 seconds and during that time, I don't have any control over it to enter credentials. Any help would be appreciated. Thanks,
