I encountered a bug in the java rules roundup applet. After I got a perfect score and clicked on the show answers button, a new question came up with only one radion button, and no submit button. Also, the ranking scale was still visible. Had to use the back button on the browser to navigate out.

I had the same problem. The first time I got a prefect score it displayed question 306 and only the false radion button with no ok button The second time it displayed question 307 and the true radio button and no ok button Very disappointing since it took me a long time to get a perfect score :-)
