Maybe this is a problem with my browser (I use the latest iteration of Firefox), but something odd began happening about 2 weeks ago and I can't figure out how to fix it.
When I'm grading a student's assignment and make a correction or comment using any of the tools at the top like the "T" or the little blue bubble or strikethrough, the screen shifts so that I can make my comment/correction on the right-hand side of the assignment. That's fine--Canvas has always done that. What it's just started doing is that I can't shift the image back to view the entire assignment: its left-hand portion is off the screen. The only way I can re-center it is to reload the page. That was never the case before: Canvas always re-centered the assignment after I made my comment/correction.
I've tried zooming out, zooming in, hitting the "Enter" key, clicking on the assignment itself...nothing works. I have to reload the page.
Am I doing something wrong? Or missing a step?
