Captivate SCORM Package Javascript Error

A co-worker has exported a SCORM 1.2 package out of Captivate 9 for me. I am working on implementing a simple viewer for this. It works for the most part. However, when I navigate away from the SCORM package content, I always get a "topWindowBeforeUnloadHandler is undefined" javascript error. Does anyone have any insight into the source of this error message? It is coming out of CPM.js, which is a part of the SCORM package. Is there some configuration that I need to do on my viewer to avoid this error message or is there perhaps a setting that needs to be changed within Captivate before exporting the SCORM package?
