SCORM Activity Completion Issues!

Hi

This issue does not appear to be going away - in fact, it seems to be getting worse for us.

It's very strange, as we have not made any updates to the LMS and the SCORM packages are as they have been for 6 months without issue.

This isn't affecting all users and is all coming up ok in SCORM, but there are issues in recording the course completion for a number of users.  Worse still, is it is affecting a whole variety of courses.  It is almost as if there is something browser related occassionally preventing the completion status from passing - similar to how the Flash issues sometimes prevent course interactions (despite being published to HTML5 with Flash back up).

Am I alone in this or are other users still experiencing issues?
