[ui-dialog] Problem when using JQuery with asp.net (ajax enabled)

When I have a scriptmanager inside my page and then I try to use the jquery ui, I have a conflict at the following block of code:

prop: function( elem, value, type, i, name ) {
		// Handle executable functions
		if ( jQuery.isFunction( value ) )
			value = value.call( elem, i );
			
		// Handle passing in a number to a CSS property
		return value && value.constructor == Number && type == "curCSS" && !exclude.test( name ) ?
			value + "px" :
			value;
},

I actually create a dialog window dialog as following and when I drag that window or click on it I have an error:

$('#skillInfo').dialog({
	title: 'Add a new skill',
	draggable:true, 
	width: 640, 
	height: 480,
	autoOpen: false // do not open automatically the popup
});	

In firefox when i load the page and then open the popup every thing is fine, but when I open it in IE I have a conflict saying that the type is not valid.

(If you need a screenshot, i can send one)

Actually to make it work, I did a small fix as shown bellow, but maybe it should be fixed differently.

(approx line 186)

return this.each(function(i){
			// Set all the styles
			for ( name in options ){
				if (name != "localeFormat" && name != "format"){ // Quick fix to work with the asp.net atlas (ajax).
					jQuery.attr(
						type ?
							this.style :
							this,
						name, jQuery.prop( this, options[ name ], type, i, name )
					);
				}
			}
		});
