Navigation Menu Error jQuery
<p>I'm trying to create a menu, but when you change the horizontal tab, vertical position is not updated, so when it goes back (when you go forwards works) it fails. </p>

<p><em>So, if you on "Applications", and you press the down arrow of the keyboard, and then you go to "Games" and later you go back again, it says "position:auto", it should say 160px.</em></p>

<p>Using the developer console, you can read "position: X" when you change the horizontal tab.</p>
