Hi: I am running Nitro Pro 11.07 on a Surface Pro using a Surface Pen. When I select "draw," sometimes the software allows me to underline. Sometimes it treats the pen as a finger using touch gestures moving the document around on the screen. A few updates ago, I was also able to add drawn notes in a PDF. Now that has become almost impossible, with the application treating the pen as touch gestures in the midst of making a note. The pen works fine in other applications and, for instance, making notes in browser pages (html). I do not see any settings available in Nitro Pro that would affect this behavior. Suggestions?
