User Account (administrator) lost cursor on scren saver login
One of my administrator accounts would go to screen saver and when it awoke to the password login form, other users couldn't get the mouse cursor so they could switch users. Finally cured (?!) it by renaming user preferences folder loging out and back in and moving non-Apple preferences back afterwards. Any idea which Apple preference it was?
