I very much appreciate the fact that the chess board resizes automatically when I resize my window. It is a problem, however, that the column to the right of the chess board does not automatically resize...along with the chess board. I never play with just one window open. I prefer to have several windows open at the same time...with none of them filling the entire page. That is a problem with v3. If I do not have v3 open in a nearly full window, the submit button is not accessible.
