Resizable bug in IE with proxy

Resizable bug in IE with proxy


Anyone else having trouble using 'proxy' in IE?
My code looks like this:
$('.resizableColumn').each(
        function() {
            $(this).resizable({
                handles: { e:$(this).children('.dragHandle') },
                proxy: '.proxyClass',
                stop: function () {
                    resizeCols();
                }
            })
        }
    );
FF and safari have no problems with that, IE 6 and 7 both blow up
after resize is completed. Specifically, they return the error
'Invalid Argument'. It seems from my debugging to be throwing the
error from within jquery-1.2.3.js on line 1111, second line here:
if ( value != undefined )
elem[ name ] = value;
Anyone else having this issue with proxy? If this is actually a bug,
I can open one, but perhaps I'm just using proxy wrong or something
else entirely...
Thanks
