Fade Loop Li's and Update the Content

Fade Loop Li's and Update the Content

Hey,

I currently use this to go through a group of li's:

$(document).ready(
    function(){
        $('ul#random').innerfade({
            speed: 'slow',
            timeout: 5800,
            type: 'sequence',
            containerheight: '200px'
        });
    });


I also want to update that content though every couple of minutes so I use this:

function updateTwitter() {
   $("#random").load("system.php");
}
window.setInterval("updateTwitter()",180000);


This updates it, but also freezes the fading loop. I tried doing this:

function updateTwitter() {
   $("#random").load("system.php");
   $('ul#random').innerfade({
      speed: 'slow',
      timeout: 5800,
      type: 'sequence',
      containerheight: '200px'
   });
}
window.setInterval("updateTwitter()",180000);


But that doesn't work either. Can anyone help me with getting the fading loop to continue looping while having the content update every couple of minutes?

Thanks in advance for any help!
