We're running Moodle 2.1 and I've got some HotPot exercises that include images and audio and they work fine. However, after completing the exercise and clicking on 'Check', a dialogue box appears, giving your score but, almost before one can read it (i.e. after about 2 seconds), the whole exercise closes and returns to the course. This only happens when all answers are correct.
Does anyone have a thought as to what might be causing this?
