Hello, I have two questions about Sonar and Jaws. 1. As far as I know, it is possible that blind person can use Sonar with Jaws. By the way is it possible use equalizer function in Sonar with Jaws? In other words, can I use Sonar perfectly with Jaws? 2. In order to use Sonar perfectly, can I use Jaws 11 also or only 12? Please reply to me. Thank you.
