Is there a way to turn off SpeedGrader from auto-opening Excel files? My entire class submits Excel files and I zip them up and download them offline to review/grade. I then go back into SpeedGrader to provide feedback, but once I do the system is slow in trying to auto display the Excel files (I'm talking several minutes slow). Chrome thinks the page has become unresponsive and wants to stop the page from processing.
Having the ability to turn off the auto-open functionality across all submissions for a particular assignment would be great.
