I fill a quiz with a student account.
I go to the quiz as admin and I select "results" and then "Overview".
At the and I select the date of a submitted quiz to see it in detail.
What I get is the quiz with the list of questions and, for each question, the right answer selected by a green background... but I don't get the student answer. Is this a bug?
I have noticed similar behavior on my WIMP server running 1.6. It was reported to me after a teacher gave a quiz and was trying to go back and see which questions a student did not answer and he indicated that the student answer was not appearing. On another quiz in the same course it appears fine. The user thought that he had gone in and editted the number of attempts available and after doing that the student answers stopped showing up. I suspect that there is a bug but I have not had a chance to track it down.
