Thanks for the help but that didn't work. I clicked on Properties at the Start Orb and at the Start Menu tab, the power button action was set to Shut Down. My options are to Shut down, Switch user, Log off, Lock, Restart, Sleep, Hibernate; none of these seem to me to stop causing the computer to switch to a Locked start up screen which then will let me "Switch User".
I checked the setting on my other Windows 7 computer under Start Orb, Properties, Start Tab and it is set identically to how the Laptop that is flipping back to Switch User and Locked is set.
Why is the Laptop continually flipping to Switch User? Could whatever setting that is causing this have something to do with the "Locked" status?
