Quiz stopping before the end

Hi,

I'm converting a quiz from Captivate 6 to 7 and using the Submit All button. The problem I'm having is that when the quiz gets near the end (at the second last question or so) it does one of two things:

• it keeps returning to the previous question when "Next" is clicked, even though it worked fine for all the other questions
• it doesn't do anything when "Next" is clicked

In either case, the result is that I can never finish the quiz.

I am using question pools and shuffling answers. The quiz works as expected in Captivate 6 but not when I use Captivate 7.
