Actipro RibbonWindow and slow Startup of application?

protected override void OnStartup(StartupEventArgs e) {
    base.OnStartup(e);
    var demoWindow = Application.LoadComponent(new Uri("MainWindow.xaml", UriKind.Relative)) as Window;

    // Start-Uncomment this to load faster.
    // demoWindow.Width = 50;
    // demoWindow.Height = 50;
    // End-Uncomment this to load faster.

    ThemeManager.CurrentTheme = "Office2007Black";
    demoWindow.Show();

    // Restore desired size.
    demoWindow.Width = 800;
    demoWindow.Height = 700;

}
