I'm having trouble logging on to my XP Pro machine. Everything is fine until I try to click on my account name, but I can't click on the account name. The mouse cursor never changes from the pointer to the hand. If I hit ctrl-alt-del I can type in the user name and password, and hit enter, but it just beeps and says the user name or password is invalid, even though it is the correct user name and password.
I get the same problem starting in safe mode.
