Thanks for the suggestions, but neither one of them will work.
Emerald,.... the screen is at the place where it says Administrator and has a blank for you to enter the password, which we dont have. I did try no passpword, still no luck.
saga lout,... No we do not have a logon alongside the administrator one. There is no start button, or bar along the bottom of the screen. The only options we have are to put in the admin password or to shut off the computer.
