That is odd indeed. What web browser are you using? I tried it with FireFox and Chrome, and in both cases it said "I resign" without moving.
One other test we can do: when you open the piece table by clicking on "here" under the diagram, and then click on the "move" header of the move column, it should switch to displaying the piece values it estimated. (Don't take those too seriously! They are often very inaccurate, but good enough for playing against someone who desn't know the piece values either.) Behind the King it should also print "(c00)", though, to indicate that it is royal. One of the explanations for what you see is that it somehow did not get through that the King is royal.
