I tried the suggestion Michael posed, logging in as one user then switching to another user while that first user is still logged on. Doesn't work if you do something like you walk away overnight and come in the next morning. In my case, I'll come in the morning, switch from one computer to my Linux box via hitting a kvm switch button, and I will see a prompt for the first user's password, but the user session I switched to is gone. I thought maybe the first user's screen saver was screwing things up, but I have disabled the screen saver.
