Can you possibly split the course into two courses--like Part 1 or Part 2?
Does your LMS support multi-modules? Basically the same as above except it's all "one course" with two modules the learner has to complete.
Ironically, this course is replacing a much longer course we originally were planning on splitting in two. As far as number of slides and duration, this one is much shorter than it's predecessor. So I'm pretty sure suspend_data is affected by many more factors than number of slides. This new version of the course (although much shorter) is media rich, so I'm guessing this is part of the problem.
I have changed most slides to "Reset to Initial State", seems to help to a certain extent. Just whish I knew what else to try.
