Write protection has to be off (When you install Shredder9 this is done automatically for you. The 2nd situation is that you must rightmouse the tree window and click Allow move adding. The situation about bogus move statistics is that sometimes if you add a move or a couple of moves to the tree, you will get move statistics for one of the moves. At first I thought it was because of an unplayed transposition move, but I have that option clicked on . If there was an unplayed transposition and I actually added that move to the tree then the transposition would show and I should have more options at the next node. In certain bizarre situations, that doesn't happen because there isn't any actual transposition and yet it shows the retro move(I also have that option checked on as well) with move statistics. If this wasn't a bug, then that would mean that now that there was a transposition, you should see move options for this move in the tree opening book move window. Many times the move options don't show therefore there couldn't have been an unplayed transposition with move statistics. I will investigate further this problem.
