I just took my five question quiz in IE and got the lowest ranking after answering all five questions correctly. Weird. I can't even remember the last time I used IE to be honest. I tried it because a friend also got strange results using Internet Explorer. (IE8)
When the CORRECT answer is selected in IE and check answer is selected the INCORRECT answer text is displayed. Duplicated on two two different PC's using IE8.
IE does not appear to understand the code used in the theme or the plugin. Reminds me of the days when as a software producer our beta teams had to test everything in every major browser. I thought we were long past that. Rats.
