I have bought ebooks on (ADE) and when I scroll up and down it makes a sound which can be very distracting when studying as I read textbooks to study with. does anyone know how to stop the sound coming when I arrow up and down. I have a macbook white 13' with maverick installed and tried going over my keyboard shortcuts and phoned apple support and they said contact Adobe. I have tried opening preferecnes in this app and open with usual keyboard shortcuts in my usual pane. But page and down does not make any noise but soemtimes I want to scroll down only a couple of lines. I do someone is havign the same problem as me do reply. Await a response.
