  1. Hi Lucas,
    terrific work!

    Usted merece una estatua!
    (have i written it right?)
    On my first quick try, I'm having these problems:
    "Determina tu potencia de càlculo" and "Comprueba tu memoria sobre un tablero"[they freeze when the message "Un momento por favor" is showed on the screen]
    Kind regards,
    Stolcius Von Stolcenberg

    1. Thank you very much,
      I have tried to fix them.
      A new distribution is available.

  2. Tnx, Lucas: fixed! :-)

    I've spotted another little bug.
    After having analyzed a game, i click on "Show graphics", but nothing happens.

    Best regards,

    1. When "Show graphics", program creates a html file, then say to OS to open this file with the default program, and this is usually the default browser.
      File created is histoA.html in the html program subfolder.
      Can you read this file with browser ? or are html files associated with default browser in your PC?

    2. Solved: the problem was with my browser configuration.


  3. Hi, Lucas,
    Adjourn function doesn't work with "Elo Ratings" & "Training Ratings".
    - I push the button
    - LC shuts down
    - At restart the chessboard is empty and frozen

    Bug.log is empty
    On the other hand, with "Play against an engine" it works correctly

    Best regards,

  4. Lucas, thank you for your excellent work. I have a question. How can I add my pgn positions for the my analysis in training "determine your calculating power".

    1. It is not easy to add.
      I add your suggestion to the pending list.

  5. Lucas добавить функцию "сеанс одновременной игры"

    1. Hi Husniddin, I have not forgotten your suggestion about simultaneous chess games, it is pointed in my list.

  6. Amazing program; just keeps getting better! Thank you!!
