I've got quiz on my site realized with jquarks.
it worked fine on old versions of sj news, but It has conflict with sj news v2.0

When I start quiz, I can see the first question. If I choose answer and click next button I'll see clear page. Pages of all other questions are cleared too.
It's because the width of them are 0. It should change dynamically from 0 to some value, to show or hide questions.
I can manually change the value in firebug from:
<div style="margin: 0px; position: static; overflow: hidden; width: 0px;">
to
<div style="margin: 0px; position: static; overflow: hidden; width: 700px;">
and I'll see question normaly.

Quiz work fine if I change template from sj news to joomla default (beez2).
The page of quiz start is:
anapavoa.ru/index.php/component/jquarks/quiz/1

p.s.
It seems to me that there is some problem with mootools.
