Yes i saw that, when correcting the drawing speed of the stats i introduced a small bug, i will correct it today.
Change the board: you have 2 boards available, in preference-> board, if i have the the permission of the authors i can adapt the boards from BGBlitz as they use a near data format. but it's difficult to find their Email.
Resize the window : not possible, board and checkers are bitmaps, they don't resize. All what i can do is include a larger board.
