Hi Greg - Can you give me a little more info? How are you getting to this preview? Which tool are you grading? Which side of the screen is the sidebar?
I go to the grade link and then the downloaded file is listed. When I click on the file to open it then the sidebar comes open on the left of the preview. I get to the preview by clicking on the submission icon for each student. Now sure what you mean by which tool are you grading? Thanks.
