      This is really hard to test - you must have IE 6 installed with all sorts of stupid locked down settings in place - I know IE 6 isn't officially supported in 2.0 but I've pushed the fix there anyway.

      It should be sufficient to test an existing "working" SCORM in IE 6 and make sure it still works after the patch has been applied.

      Description

      the script mod/scorm/player.php outputs the API link in the following fashion (e.g.)...

      <script type="text/javascript" src="api.php?id=624&scoid=1713&mode=normal&attempt=34"></script>

      However, api.php generates a content-type header for mimetype text/html which is wrong. It should be application/x-javascript. It's probably rarely done but it is possible to set IE security settings to block such a link which breaks SCORM.

      Looking at the code, the API wrapper doesn't really seem to be written to suit being embedded as pure javascript (e.g. require_login() and possible error messages) so I'm not sure if this is easy to fix.
