ajaxcontroltoolkit drag drop

[gerry]

I have been playing with the AjaxControlToolkit drag&drop.
Things work consistantly well across all browsers that I'm testing on.
But I notice that when dragging over a non-drop target area the 'no-drop'
cursor is only displayed in IE.
This happens on the demo site as well so I am assuming that this is not
something I have done.

I'd like to look into why this is the case but so far I haven't been able to
locate where the cursor is being set.
Can anyone point me to the proper script location ?
