Previously answered question pops in again at the end of Quiz
I built multiple quizzes in Quizmaker and pulled them into a Presenter course. I published to the Web to e-mail and share the package with my reviewers. Every now and again, as I work through the published course, a previously answered question appears again at the end of the quiz. For example, question 2 pops in again after question 5. It doesn't happen every time but has occurred more than once and for 2 different quizzes.
The questions are not randomized, the answers are not randomized. I use blank slides to introduce a situation that is followed by 2-3 questions about that situation, then another blank slide with questions.
I am using Studio 09, PPT 2003. Any ideas as to why this happens?
