Steps to Reproduce Behavior
---------------------------

1. Create a new Standard EXE Project.

2. Place two ListView controls on the form (ListView1 and ListView2).

3. Place the following code into the General Declarations section of the form:

      Private Sub Form_Load()
          Dim Li As ListItem
          Set Li = ListView1.ListItems.Add(, , "hello")
          Set Li = ListView1.ListItems.Add(, , "hello2")
          Set Li = ListView1.ListItems.Add(, , "hello3")
      End Sub

      Private Sub ListView1_MouseDown(Button As Integer, Shift As Integer, _
      x As Single, y As Single)
         Set ListView1.SelectedItem = ListView1.HitTest(x, y)
         ' In the following line any ICO file will do
         ListView1.DragIcon = LoadPicture _
         ("C:\program files\microsoft visual basic\samples\calc\calc.ico")
         ListView1.Drag vbBeginDrag
      End Sub

      Private Sub ListView2_DragDrop(Source As Control, x As Single, _
      y As Single)
         MsgBox "Hello"
         Dim li2 As ListItem
         Set li2 = ListView2.ListItems.Add(, , Source.SelectedItem.Text)
      End Sub

4. Run the form and attempt to drag "hello" from ListView1 to ListView2. Note
  that the drag icon disappears when the item is moved.
