@nadasax - the test questions (and answers) aren't annotated for the tests for hopefully obvious reasons, although we do check the traditional and pinyin forms so that people can select their preferred display format.
Between this and the issue with apostrophes, it sounds as if there is something really strange going on in your browser support for javascript -- as soon as the page loads javascript should disable the function that provides the popups. I still need to look into the issue that you're having with Internet Explorer, but it sounds like this might be related. If you can invoke a popup after the page loads that is definitely not supposed to be happening and a sign that javascript is behaving strangely.
