Okay, my father is having problems with his computer. He has a Power PC G3 (IMac) running Mac OS X 10.1.5. The problem is...something is wrong with his keyboard. Whenever he types in any application, the letter come out wrong, usually as symbols. When he types a number, they come out as symbols, but not the symbols you would get if you pressed shift. However, when he does hit the shift key and a number, it comes out correctly. Does anyone know how to solve this problem or what might be the cause? He can't use his keyboard at all because all the letters come out wrong! He says that he didn't change anything in system prefs and that he didn't change anything in any applications. Help!
