I just encountered what may be the same defect in the Nurikabe implementation mentioned earlier-- I was unable to click OK and exit the final "Game Completed" dialog. Each time I attempted to do so or to kill this dialog, another one appears.
The initial default 5x5 game is the one that appears on the J wiki page http://www.jsoftware.com/jwiki/Essays/Nurikabe , so it should be easy to re-produce the problem. Unfortunately, the only way to exit successfully is to kill the "jqt.exe" process from Task Manager. Another mis-fortune is that this demo, unlike the others, does not appear to have a button to display its source code. I'm looking at the nurikabe.ijs file in the "games" section under the assumption that this is the one loaded.
