Yes, sorry CG, (or more properly sorry Random !)
I never have a logon screen for Vista or XP (or ME come to that). I always organize it that the system comes straight up without going through that multiple-user business, so when I see "logon" I just think of booting the system, and I'm afraid I'm guilty of seeing what I thought, instead of what I read.
Guru's quite right Random. If you're getting a normal boot up to where you'd normally get a logon screen, you don't need to "repair startup", but use the other option on the same page to select a system restore point from when everything was still working properly.
Don't worry if you've already seen and acted upon my previous advice. You won't have done any harm. If there's nothing broken, it won't fix it.
