[jQuery] jquery.corner.js plugin not working with <input> elements

[jQuery] jquery.corner.js plugin not working with <input> elements


I must have missed a bit of information, because I cannot get the
jquery.corner plugin to work with <input> html elements. The following
renders a rounded div but not a rounded input element in FF3, IE7,
IE8, and in fact causes the input box border to disappear completely.
<html>
<head>
<script language="javascript" type="text/javascript" src="../Scripts/
jquery-1.2.6.js"></script>
<script language="javascript" type="text/javascript" src="../Scripts/
jquery.corner.js"></script>
</head>
<body>
<script type="text/javascript" language=javascript>
$(document).ready(function() {
        $('div.round').corner();
$('input.round').corner();
});
</script>
    <div class="round" style="background-color:#bbb;">
        

lorem ipsum dolor sit amet.


    </div>
    <br />
    <input id="Text1" value="lorem ipsum dolor sit" type="text"
class="round" />
</body>
</html>
In IE7/8, a javascript error message is logged:
