freezing on shortcut test
twice I've taken the shortcut test and just before the end it freezes. Internet otherwise working fine.
What type of internet connection do you use? Are you behind a proxy? I tried to replicate but am having difficulty doing so.
I'm having this problem as well. Frequently, when I enter an answer, it just hangs on "grading" and never gets to the next screen or the results. I can reload the browser (Firefox 30.0 for Windows) and go to the next question, but the previous question is never resolved.
