Problem with jQuery dialog

Problem with jQuery dialog

Hi,
I am using jQuery dialog with the following options.
<div id="componentPopup" style="display: none;text-align: center;z-
index: 2000;width:auto">
</div>
$("#componentPopup").dialog(
{
autoOpen : false,
closeOnEscape: true,
draggable: true,
modal: true,
position: "center",
resizable: false
});
Before opening the dialog I am setting some more options
$("#componentPopup").dialog("option", "position", "center");
$("#componentPopup").dialog("option", "width", '800px');
$("#componentPopup").dialog("option", "title", 'this is a
dialog');
$("#componentPopup").dialog("enable");
$("#componentPopup").dialog("open");
When ever the data will be more horizontal scroll bar is not coming in
IE8.It is working properly in Firefox.If I remove width option or
putting the value to auto my window is not looking good but still the
problem is there.
Regards
kondal
