John D.Well, it seems your suggestions are all workable but have failed to solve my problem. I was successfully following the SAFE MODE And ADMINISTRATION account check in which every thing worked perfectly including the background selection!! After re-booting and returning to my control panel it was still not allowing me to click on the background selection ,so, same ole story,the DESKTOP selection is still useless.Certainly there should be some simple way of rejuvinating these display properties!!!
