How do I get a window (form) to redraw as it's being dragged?  The form in question is set to always be on top.  This is a class that  inherits "Form".   Here the code that sets the style and exstyle for the window:

 
Protected Overrides ReadOnly Property CreateParams As System.Windows.Forms.CreateParams
        Get

            Const WS_SIZEBOX As Integer = &H40000
            Const WS_EX_TOOLWINDOW As Integer = &H80
            Const WS_EX_NOACTIVATE As Integer = &H8000000
            Const WS_EX_TOPMOST As Integer = &H8

            Dim params As CreateParams = MyBase.CreateParams
            params.Style = params.Style And (Not WS_SIZEBOX)
            params.ExStyle = params.ExStyle Or WS_EX_NOACTIVATE Or WS_EX_TOOLWINDOW Or WS_EX_TOPMOST
            Return params

        End Get
    End Property
