Hello guys: the braille display on my braille lite started having some stuck dots. So, AI decided to clean it with some cotton and alcohol, But I think I did the wrong thing. Now all the dots are stuck. Any ideas please? All my music parts are in there. And I like to use it a lot for taking notes silently. In the meantime, is there anybody who can recommend or give a comparison between note takers with braille displays? thanks a lot. Douk
