Hi, all. I just installed Perky Duck on my MacBook Air M1, running Mac OS 13.4.1. when I begin to create a Braille document in Perky Duck, and I'm using the home row for Braille entry, nothing shows up on my Braille display. I'm using a Brailliant BI-40X. Perhaps I need to update to 13.5of Mac OS? My student says she can read what she is inputting on the Braille display. My Braille display shows a cursor moving, but there are no Braille dots. Thanks for any help since Perky Duck is free and is without support. The Help menu is also not navigable which is not good.
