AJAX_Marking v2.1.5b7 on Firefox 11.

This may be one problem or two different ones:

1) The marking window does not have a "Revert to draft"/"prevent new Submissions" button like the grading dialog does.

2) The list of response files does not load. The spinning circle icon runs until I close the window.

Javascript error reported as the grading dialog opens:
Error: YAHOO.util.Event is undefined
