It seems that the moving of a form happens before the message interception of "WM_MOVE" by WinProc.

protected override void WndProc(ref Message m)
        {
            if(m./// == ""WM_MOVE)
            {
                return new Message();
            }
            else

                base.WndProc(ref m);
        }

public const int WM_MOVE = 0x216;
private bool m_AllowMove = false;

[StructLayoutAttribute(LayoutKind.Sequential)]
public struct WM_MOVERECT
{
    public int Left,Top,Right,Bottom;
}

protected override void WndProc(ref Message m)
{
    if(!m_AllowMove)
    {
        if(m.Msg == WM_MOVE)
        {
            WM_MOVERECT lParam = (WM_MOVERECT)m.GetLParam(typeof(WM_MOVERECT));
            lParam.Left = this.Left;
            lParam.Top = this.Top;
            lParam.Right = this.Right;
            lParam.Bottom = this.Bottom;

            Marshal.StructureToPtr(lParam, m.LParam, true);
        }
    }

    base.WndProc(ref m);
}
