Trying to get through the quiz for ‘the DOM’ section. Can’t seem to click through the quiz questions – or rather can click through some, but then it stalls on others. Gone through it twice now after it stalled on Question 7. To be clear, this is not about getting right or wrong – I click the ‘continue’ button and nothing happens or even if it does, takes a minute or more to click through provide ‘correct’ or ‘incorrect’ and click through to the next question. The first time the quiz stalled on question 7, second time on question 3.
