How does one un freeze the lessons without losing your current status. This has happened to me for three days now and it makes me want to stop duolingo.
This is the sixth time that has happened to me. The reason i don't think the problem is on my end is that whenever i'm waiting for Duolingo to respond (to anything) there is a little circle chasing its tail in the Duolingo menu bar and eventually the response comes. At these end-of-review-session (and it's always only at the end of a twenty question session) freezes, there is no such circle. I can open the Report a Problem window, so my machine hasn't locked up.
I'm really enjoying Duolingo -- kudos to Christine and the crew. Thank you!
