Course Marked As Complete As Soon As Course is Opened in Firefox

I am using Lectora Inspire X.4 and Firefox 21.0. Published in SCORM 1.2.

I have 45 pages and when the 45th page shows it is set to modify variables AICC_Lesson_Status and AICC_Score and then send the completion info to Saba's LMS. This setup has worked perfectly previously in IE 8 and 9; however, when I use Firefox, it marks the course complete as soon as I open the first page. This is also happening in IE 10. If I use compatability mode it works fine.

Is anybody else experiencing this or have any workarounds (besides using compatability mode)?
