I have been using the vector board, and a bug causes it to occasionally lose sight of checker moves. I haven't used any of the non-vector boards, because they don't come anywhere near to filling my main monitor. I made my first effort at a board, and it crashed JavaFibs.
I don't know whether this is due to a mistake in the metric files, or the board dimensions being out of range, or some other error. Does anyone know if there is a limit to the size of the board you can make? Mine is 1400X1080.
