When I run out of hearts, then make one more mistake, the page with my wrong answer and the correct one below flashes onto the screen & then immediately vanishes before I have time to read it, throwing me back to the start of the lesson. Are others having this trouble?
I'm on a desktop Mac using OSX 10.9.2. I was doing the lesson on strengthening pronouns at the time. I just tried the same thing (using all hearts & giving a wrong answer) on a different lesson & it worked fine. I could see the right answer & request to see my own wrong answer.
