Since my last question, I have actually taken advantage of the accidental disappearance of the dragged item. I use the disappearance to represent a
deletion of the item --- a "swoosh" and delete of the pointer.
I now keep track of whether the user has exited the ListBox and deleted the item (accidentally or by mistake)
by keeping count of how many times the user enters
and leaves the Listbox --- not too elegant but it works.
Is there a simpler alternative? I already have an explicit "Delete" button for the first-time user who is yet unfamiliar with the behavior
of the GUI.
