Something wrong when I crate LingQs from a phrase

Recently, something wrong when I create LingQs from a phrase. I’m using FireFox 3.5.5 on Win XP. I usually highlighted a phrase and hover on it, then a pop-up appeared automatically.
But now, I cannot get any pop-up when I highlight a phrase and hover on it. It works properly, when I highlight a word.
I know I can copy and past it in the vocabulary, but it takes much time.
My friend also have the same problem and ask me to the support about this matter.

I had the same problem just now, using Safari 4.0.4 on Mac OS 10.5. So I suspect it’s not a problem with our browsers or operating systems, but a problem with the LingQ software. Cheers, J

Hi, there is a problem that seems to affect some lessons and not others. We are working to fix it.

I have the same problem too, I’m glad to see its being dealt with ;DD
