Hi,

I couldn't find a ticket describing this problem, so sorry if it's a duplicate.

IE9 (win7) seems to throw an error:

SCRIPT65535: Invalid calling object

jquery-1.7.js, line 6002 character 5

When running trying to append newly created elements assigned to a variable:

<ul id="test">

<li>An item</li>

</ul>

$(function() {

item = $('<li>Should be first</li>');

$('#test').prepend(item);

});
