If you are unable to see the entire tutorial screen or cannot view the player controls at the bottom of the tutorial screen, press F11. This will take you to fullscreen mode. You can press F11 again when finished, or simply close the tutorial window.
Each chapter of the tutorial should load quickly, within 3-5 seconds. However, it is possible that network traffic or connection issues could affect load time. If a chapter does not play immediately, pause playback and wait for approximately 30 seconds before restarting the chapter.
