Idea -- when a piece is taken off the board, keep it on screen, but in a box on the side. That way it can be reinserted onto the game board with the usual click-click.
Often, in addition to the bug (part one of which I ran into for the first time today) I delete a piece by ...[text shortened]... ion. Also handy for when a pawn promotes - you can just replace it with the required piece.
good ideas... with luck someday these things will work!
For now, I use Winboard to do my real lines. You can back things up, and save separate lines if you like for further study from games.
So, with luck the RHP board will be fixed up some day, but if you like for now give Winboard or Xboard a try....
