.net - WPF Wait Cursor With BackgroundWorker Thread

I want to show the hourglass cursor and disable the window while a BackgroundWorker process runs in another thread.

This is what I'm doing:

Private Sub MyButton_Click(...)
    Dim box As New AnotherWpfWindow()
    box.Owner = Me
    ...
    box.ShowDialog()
    If (box.DialogResult.GetValueOrDefault = True) Then
        Me.IsEnabled = False
        Me.Cursor = Cursors.Wait
        MyBackgroundWorker.RunWorkerAsync()
    End If
End Sub

Private Sub MyBackgroundWorker_RunWorkerCompleted(...)
    UpdateInterface()
    Me.IsEnabled = True
    Me.Cursor = Cursors.Arrow
End Sub

The window becomes disabled like I want, but the cursor remains an arrow. How can I make it the Wait cursor?

It seems to work for vg1890 according to this question: Disabling all but one control in a WPF window

Another way is to change the cursor globally, is..

Mouse.OverrideCursor = Cursors.Wait;

//Do something
//...

Mouse.OverrideCursor = null;
