deleted .... again!
several times i have been part way through an exercise and it is suddenly terminated and i have to start all over again. is your computer or mine at fault?
A mistake hitting the "enter" button might cause your browser to refresh. Happens to me a lot.
I have this problem also. It started when I got a new iMAC computer. Please help. I am not touching the mouse or the track pad. Is there a time limit, though it doesn't seem tied to time. HELP.
If it keeps on happening with different browsers and/or different computers, I suggest you to use the "Support" tab on the left side of the site to see with the Duolingo team if there is a problem with your account. But if it works normally with at least one browser and/or computer, then the problem is more than likely on your end.
