When I preview the test, it works fine. If I publish the quiz by itself, it works. But when I publish it within the course, after 2 questions, I get a small rotating circle which just stays and freezes the entire pane. ESC doesn't work. I tried removing the previous slide which had an embedded object that might have been a factor, but that didn't help. I'm stumped. Anyone have any ideas? Something is corrupt but what and where?
