An important note about 'refreshing' your question page.

Note that everytime you display a Question, the order of the answers change.

So, it's very important that if you ever look at a question in more than one browser window (for example, show a question, and then open a new browser to go look at the 'hint' web-pages), you must REFRESH the browser you're going to use to actually answer the question.

If you don't make that your current, refreshed browser, it's possible that the "correct answer" in a stale browser, would no longer be in the same position, and it will be marked as 'wrong'.      oh noooo!

Simply refreshing your browser, if you may have displayed the question in another browser window, will prevent this problem.

Sorry if you encounter this!
