I am having a real problem with the DUOLINGO website.
I have a 3 month old i Mac Computer. On the DUOLINGO page where I do the exercises, way over on the left-hand margin is a small white tab which says "Support." Frequently, as many as three times a day while I am trying to go through a lesson that white tab moves to the left and all of the lesson disappears and I have to start over, even if I have gotten everything correct up to that point. How do I prevent this?Anybody else have the same problem?
Thanks for your comments. It's still happening, so that it takes me twice as long to do a DUOLINGO lesson. I would like to contact DUOLINGO directly to ask them what to do because, if this continues, I will have to give up on DUOLINGO which, otherwise, is a great way to learn or brush up on Spanish. Does anyone know how to contact DUOLINGO directly? I haven't found a way to do that yet. Thanks.
