I discovered a problem while trying to follow along with the Cross Country Navigation lessons with my Navigraph app (windows 11) open. The problem is your video has the old window view or the Full Screen view options, neither of which are optimal for plotting the course on the Navigraph app as it is being shown in the video. For the future, I suggest you add the Theatre view option, so that the lesson can occupy its entire window while allowing the useability of the Navigraph window.
