The function LMSInitialize() call a second time with an error response

HI,

We have a file .story that produces bug in LMS (Scorm 1.2 ou 2004 the same) when the learner comme back inside. 

In fact, we have differents versions of the projet depending on the client and the problem is present only on one file.

I investigated to find that the function LMSinitialize() is call a second time and produce an error, so the communication betwwen LMS ans Scorm failed down.

I put one slide of this file in a new projet it is ok, for the second one we get the trouble. I looked to the masks and found that with new mask based on a new master, it,  sometime,  works great. It is like when I import the slide, I import the bug.

Has anyone ever had this problem?

Thak you for your ideas
