OK, am I crazy? This semester, I look at the submission form (I'm talking about the little square that pops up when I click on the submission in the gradebook, and that says "More details in the Speedgrader") and then go to Speedgrader and grade the submission itself. So far, no problem. The problem is that the little "More details in the Speedgrader" box stays open as a tab...so when I've graded several submissions in a row, I have a slew of tabs open at the top, all of which I have to close manually! Didn't Canvas used to function so that once I graded the submission, it disappeared from the tab? Or again, am I crazy?
