Hello everyone, my flatmate has the weirdest problem. On his Mac Mini G4 (Running 10.4.8), the @-Key doesn't work: Pressing alt-L does not produce an @ in any application. At first we thought that it was a hardware problem with his keyboard, but the bug occurs with every keyboard we've tried (including mine that correctly produces the @ on my mac). I searched the web and found nothing that could help; does anybody have an idea? Thanks, Bertolt.
