jQuery pop-up menu on Internet Explorer
<p>Here - <a href="http://desandr.ci-team.ru" rel="nofollow">http://desandr.ci-team.ru</a> (mouse click on "КАТАЛОГ")</p>

<p>On FF and Chromium works fine - on "mouse in" under element shows menu.
On internet explorer 8 - nothing. </p>

<p>What's this, and how i can fix that?</p>
