I've inserted several quizmaker slides into a Presenter 09 course. They work fine in preview mode. However, when I publish the course, the quiz slides get stuck on the preloader and do not move on to the question. I've never had this problem before, so I'm wondering if a setting is messed up. Any ideas what could be wrong? Also, in this same course, the video does not play, though it works in others...maybe this is a related issue?
