I am running 10.7.2 on a new MacBook. I've created Admin accounts/users and in the first I chose "Display Log-in Window as: Name & Password". Now all subsequent accounts/users are set that way and no matter what I do [including unlocking the lock at the bottom of the window] I cannot switch any of them to "List of Users". PS. This machine was not set up from an image. Thanks for any help with this.
