I'm still occasionally losing speedgrader comments because I fail to click on the "submit comment" button. I'd not be surprised if others have the same problem. Students ask me: "Why did I get graded down...", and when I look, I sometimes find that there is an un-posted comment explaining. I remember sometime seeing a pop-up warning something like: "You are about to leave a page with un-saved data." That is helpful when it happens, but either I miss it sometimes, or it doesn't always appear. Maybe this is Firefox-dependent.
So, I've been trying to brainstorm for ways to forestall this problem. I'm familiar with user-interface programming in general, but not so much in in web-based UI.
Would it be possible, for example, to detect three successive carriage returns in the text box for comments, and use that as a trigger to save? Can you think of any other way to minimize this problem.
