I am in the same page as you are Agent Orange. I am so glad we have this forum to share our difficulties, as I just start this PR course and am confused. My confusion is with the blip page. I have no problem seeing 3D image, but when I am trying to follow the tape instruction and reading the dictionary, I see a shifting "blip" page and my eye strains afterward. I guess I am not relaxing and not doing it right. Any advise from anybody.
