Draggable issues in Safari 3.1.1

Draggable issues in Safari 3.1.1


Hi there,
I've had problems with jQuery UI draggables when using Safari 3.1.1 -
the problem doesn't seem to manifest for Firefox 2 or IE 7.
The issue is that I can't reliably drag an element out of the div that
it's in. It either won't drag, or in my latest example it makes a mess
of the rest of the page as wall as the dragged item not always being
visible.
I'm setting an 'a' element to draggable, and that is in a unordered
list, which is in turn in a div. I've put the failing example here:

And a screen shot of the problems with Safari:

Any advice welcome!
