SCORM 1.2 video crashing browser tab when the skin x selected

I added Exported scorm 1.2 file to MasterControl Training course. The video plays fine.  When closing the video skin bottom x or top right x the tab closes.  I have a service ticket open with the MasterControl support but I'm wondering if its an issue with the Capitvate skin.  I usually count to ten before closing the video in ase extra seconds of unseen play is involved.  Any advice why the browser tab crashes.
