I have just set up a new installation of Moodle using the latest weekly build. I have found that loading a SCORM 2004 activity that previously worked fine in Moodle 1.9 will now just display blank in the new SCORM player window. I also uploaded a larger package with multiple activities and it seems that the navigation menu on the left is not loaded fully (see pic), I cannot expand the subsections to select the individual activities. However, if set to open in a new window it will play.

Another problem is that scoring seems to no longer work. In Moodle 1.9 the scores would be stored in the activity reports section of a SCORM course, however it now seems nothing is stored. (I tested this using the open in new window option).

I have attached a single activity to test.
