Technical Snag during Ethics Training

I'm not sure exactly why this happened, but while I was taking the Ethics Training test aka assessment today, I saved an individual answer, which the instructions gave as an option. I didn't realize until after completing the test that part of the screen had frozen and none of my answers were recorded. So I recommend that you not save individual answers, but instead wait until you finish all the questions and then click "Save All". I was using Firefox, but I don't know if that made any difference.
