if it is useful, after winning a game with lowest level,
as I am lucky, I got this error state that I have captured with snapshot in Opera

About the Screen 0 interface for JSChess_Engine:
for humans it is better:
1. shape of pieces than Letters (each language has its set of letters, which often is the first letter of its name: as curiosity you can recognize that Knight is N and not K for avoiding confusion with King )
2. use 2 colors very different for brightness and grouping (one with more light and in the range of warm colors, while the second more darkness and in the range of cold colors), it helps the humans to see lines (row, column, diagonals, short lines) and shapes (squares, rectangles, triangles) increasing their speed of thinking
3. use a flipping chess table because the player uses to watch at chesstable from his perspective... it is rare to see a player looking from enemy's point of view or from a side to the 2 players
4. in Screen 0 it is possible to use the mouse for take input
5. the selected cell should be highlighted with a different grade of the same color or with a blinking of the piece that stands there. At the same time the cells of available moves should use a different color of highlighting.
Well. I think to have given too much feedback.
Thanks for sharing.
