I'm back after a too-long hiatus from Skrittering, and everything was going fine until about ten minutes ago, when the little grading circle next to the word just stopped showing up. I'm using IE 9, 32-bit version, and I've tried restarting with no luck. Unfortunately, Chrome's hanging up on the study page, everything seems to load up just fine but no items are coming up, it's just "... to review" and a blank space above the study box's toolbar, so I can't check if the grading circle is working there or not.
I'm using the beta site, for what it's worth.
I remember this has happened before, but I don't remember exactly what the issue was - seems like it might have been a bug that piggybacked in with an experimental feature update or something...
