irnbru: The software is clearly bugged right now, I notice that the tree displayed in "review" mode doesn't match the actual SGF tree if you use a real SGF editor.
d4rkm4tter: For the transition phase while the new viewer is not perfect, I made a button at the bottom of the page where you can click "jGoBoard" for the old viewer.
Thanks. I much prefer the old viewer anyway, due to its consistent size and cleaner stone images.
