in my review today, when I got something wrong, review would bang away at that word/phrase for a while, maybe 4 related questions in a row to make sure I got it. I like that. Is this new or did I just find it when I changed setting to use my vocab list rather than lessons?

Also, haven't had any problems with hanging today, even though I reviewed over 200 words and did it twice. (slowed down a bit, but never stopped.) Whatever you've done, thanks and well done!
