sortables - hoverClass appears above dragged item


Hi,
I've just started playing with sortables and used hoverClass:"hole" to
display something in the "empty space" where an item can go.
However, when I drag something, it appears _behind_ the empty space
rather than above it.
The CSS I'm using for the hoverClass is:
.hole {
background-color: #eee;
width: 135px;
height: 64px;
-moz-border-radius: 7px;
border: 1px inset #ccc;
}
I've tried setting it's z-index and all sorts of things but no joy.
I'm using the latest released versions of jQuery (1.2.1) and jUI.
