I tried using position 17 in Fischer Random chess. Turns out I was unable to castle kingside, even after moving the left rook. As far as I understand the source code, in case of “ambiguous castling” such as this, a dialogue box is supposed to show up asking you if you would like to castle or simply move the king. But no such dialogue box shows up when I test the app.
EDIT: Let me add that this interface for Fischer castling (with a dialogue box) is extremely confusing and very unusual. In practically all other chess apps, you do Fischer castling by moving the king onto the rook.
