I used the draw on screen feature a lot when teaching last Fall, and appreciate it. I haven't tried using the feature since the big upgrade a couple of months ago. But I tried again today, and am having a problem. I can turn it on and use it through the bottom-left corner menu, but I cannot start the feature by using the keystroke Cmnd+F8 (and either using the fn key with the keystroke, or not using it, neither way works). I have the latest Logos, 39.1.6, and the latest Mac version on my MacBook Air.
