Strange behavior in the translation area
Lately, things have been behaving weirdly in the translation area , panels are jumping around, sometimes a sentence panel will open, and display the same sentence twice, and sometimes I will refresh the page after doing a bunch of translations, only to have Duolingo say I didn't translate them, and when I translate the same sentences again, the coin icon says I gained another set of skill points, but the feedback box will say I did not because I "already say the best translation". Not to mention Duolingo not awarding me my rating points, even after refreshing the home page.
I find that if a sentence is slow to open and you click again, that is when two boxes appear, and usually neither one works correctly. To avoid problems when this happens I skip to another sentence to close the faulty one and then go back to it later. Just a hint for dealing with this annoying problem.
