SCORM 1.2 Suspend Data--Seems Wonky to My Pea Brain

Here is what for me is a related thread. I contributed to this thread because we had lost bookmarks and courses left incomplete, and I suspected the suspend_data string. It turned out not to be that--our LMS did not enforce the 4096 limit. A major cause of loss of bookmarking turned out to be lost connections. So I used the bWarnOnCommitFail variable from Articulate (in the story.html file) to add a pop-up message for the learner whenever the connection between the course and the LMS is dropped. But now I'm having problems with the course not communicating ANY completions with the server--unless the learner finishes the course, closes the course, then RELAUNCHES the course, and then closes it again. On the SECOND close, the LMS shows the completion.  Anyone have any ideas on this one?
