weird jquery problem in IE8/7
<p>the problem starts when i use </p>

<pre><code>#mydiv{
    margin:0 auto;
}
</code></pre>

<p>all other browsers just works fine.
this is an example</p>

<pre><code>alert($("#mydiv").position().left); //output 0
$("#mydiv").animate({'left': '-=500'});
alert($("#mydiv").position().left); //output -499
</code></pre>

<p>how can i solve that? is it a common ie problem? is there any solution for this?</p>
