Course can't be re-opened after quiz section is entered

Question

Hi,
This is fairly similar to the issue in this thread: http://forums.adobe.com/message/3960460#3960460 However, it's worth a new thread, as I redsigned certain aspects of the course following research (including blogs from forum regulars on here).  I'm using Captivate 5.
E-Learning Module:  As before, I have a couple of intro slides, and then a Home screen with links to six different sections.  The user goes through each section and when they click the Home button at the end of the section, an Advanced Action changes a variable called nSection1Complete An advanced action on entry to the Home screen checks the variables and shows an image of a green tick next to each section link if that section is complete.
The sixth section is the Exam, and I've now changed it so that I use the Captivate Quiz Slides for my Exam: 11 slides, all True or False.  I've allowed a user 99 attempts at the Exam.  On Passing, the Continue button should be an Advanced Action to jump to the Home screen and put a green tick next to the Exam section link.  On Failing, a Retake button should appear and the Continue button should simply jump back the Home screen to allow the user to revisit previous sections.
So, in short, I want the user, if they fail, to have the option to retake the Exam again, or revisit previous sections.  I did find that, the images on the Quiz Results screen faded immediately upon entry, but I found that adding a blank slide after the Quiz Results slide stopped that from happening.
The Issue:  After uploading it to the LMS (Cornerstone OnDemand), I've found that if a user closes down the e-learning module after failing the exam, if they try to reopen it, it doesn't.  It just gets stuck at the Loading screen for ages.  A user can close and re-open the course perfectly well up until the point where they enter the Exam section.
Settings:  I've tried this with the four different quiz settings (Optional, Required, Pass Required and Answer All), but while the behaviour does change slightly, the net result is that a user cannot seem to be able to re-enter the e-learning if they close the module down after failing the quiz.
Does anybody have any suggestions at all?  Could it be something to do with the fact (I think) that the SCORM publishes details of the users' score after each question, rather than at the end of the Exam?  If so, is there an easy way to change this?
I'm really stuck, and any pointers or suggestions would be gratefully received.
Thanks!

I've figured this out, and thought I'd post the solution here, in case anyone else comes across this issue.
The problem revolves around the fact that Captivate is a bit buggy when dealing with backwards movement and quizzes.  My slide navigation basically meant that users had to Go through three Intro slides before getting to the Home screen.  From the home screen, they clicked links to six different sections in order, the final section being the Exam section.  Because the Home page was the fourth slide in the Captivate slide, if a user failed the quiz and returned to the Home slide, the course was a bit buggy as noted in my post above.
To get around this problem, I simply moved the Exam slides to before the Home page, and set the Quiz to be Option - user can skip.  The user then jumped forward to the Home page.  This means that when a user fails the exam and goes to the Home screen, they are actually going forward, not backwards.  This subtle change, which is completely not noticeable by the user, has completely resolved the issue.
