I'm having trouble with undo when playing a game in Winboard.
I might see that a move I made caused trouble. I back to the move in question, with "<". Winboard doesn't permit me to enter a new move, saying something like "the display doesn't match the moves."
What I want to do might be something like entering a variation.
I can do this by exiting from Winboard and editing the *.pgn file, but isn't there a way to do this within winiboard?
TIA,
Dan
