Some Course Pages Getting Stuck on Second Attempt of a Course

Hello,

We have an odd situation in one of the courses we have developed.

We have used mostly default templates in the course.

We have customised a Try Me (Assessment) in a course, with Default scoring functionality.

We have used a customised 'Retake Course' button on the Results page - with this Java script code [cp.resetQuizData();]. We have used a manual reset for the rest of the variables in the course.

The course goes smoothly in the first attempt (the screens do not get stuck anywhere).

But on clicking the Retake Course button, it sometimes gets stuck on a few screens (Forward navigation gets stuck, Backward navigation remains ok) - and Captivate throws some error in the browser console. Please refer to the attached screenshot of the error.

Would anyone have a solution to this? Please do let us know.

Thank you.
