I got this report from an instructor today, "When I am in "Grades" view, and am adding grades and comments for assignments: if I write a comment and then click "update grade", the comment is not submitted and only the grade is submitted. If I click "add comment", the comment is submitted but not the grade. It would be great if both were submitted at same time." This happens when clicking the Comment balloon in the Grades tool. It's odd to present a place to enter both grades and comments, but only one can be saved. It also closes the window after saving. This is really counter-intuitive.
