All of a sudden, every time I record, Duolingo gets stuck. I can record (again), I can stop recording, I can play back the recording, but it won't check it or move on. The only thing I can do is click on the "turn off microphone" link and finish the lesson without speech recording. This problem first started happening every once in a while and became more and more frequent until now it never works normally at all. I updated to the newest java but that didn't help.
