Thank you for your quick reply!
1. Question number one was solved, thank you.
2. This seems to be a problem with Stream quiz and explorer. This is a huge problem for me since many people sadly still uses IE. I tried your demo with Explorer and the same thing happened there. I attach a screen dump of it.
Is it possible to fix this in any way? Users must be able to use the test/quiz.
3. I want to be able to "de-click" the first answer I choose without being forced to click another answer. Example: I have four different choices when answering a question, two answers are the right answers. First I choose to click on answer nr.1, but then I regret that answer and want to "de-click/un-choose" that choice so that the box is empty. But that's impossible if I'm not click on answer numer two first and then de-click answer number 1.
4. I understand. But it would be an great function to include, because if you answer everything correct in one quiz - why would you replay it? It would be better to have a button that you could link to a new quiz or page... Is it possible to use shortcode to add a button in the quiz results page?
