Wrong layer exposed on drag

Wrong layer exposed on drag


I have a page that reveals a layer on user click. That layer is
draggable per this:
$(document).ready(function() {
$('#facebox').Draggable(
{
zIndex: 20,
ghosting: false,
opacity: 0.8,
handle: '#dragHandle'
}
);
});
Then if you click a link in the layer or use a submit button, that
layer is re-populated with new content. However, when you drag the
layer the previous content shows until you stop dragging. I have
played with z-index to no avail.
