On Moodle Moodle 2.3.3+ (Build: 20121230) changes to lib/outputrenderers.php causes SCORM launch to fail. SCORM object launch in a popup or same page ends with a blank page or a a TOC only with no content.
In current 2.3.3+ (Build: 20121230) lib/outputrenderers.php at line 1359 there is the following code, which breaks the SCORM loading:
Substituting the above code with the following code taken form a previous 2.3.2 Moodle version, SCORM objects launch correctly as expected
Hope this can be triaged and integrated soon as is affecting many sites.
