WebBrowser control zoomed out inside PowerPoint Slide

I need to have a WebBrowser control, set to a specific URL, embedded in a PowerPoint slide. I've gone with

Shape shape =    s.Shapes.AddOLEObject(0.0f, 0.0f, 720f, 540f, "Shell.Explorer.2", "", MsoTriState.msoFalse, "", -1, "", MsoTriState.msoFalse);

shape.OLEFormat.Object.Navigate2("http://www.google.com");

So far so good, it works perfectly well. However, I need to refresh the page every time the slides change during presentation. For this reason, I am doing something as follows to refresh the page: 

    void Application_SlideShowNextSlide(SlideShowWindow Wn)
    {
        Slide sl = Wn.View.Slide;
        foreach (Shape s in sl.Shapes)
        {
            if (s.Type == Office.MsoShapeType.msoOLEControlObject) {
                if (s.OLEFormat.Object is SHDocVw.IWebBrowser2) {
                    SHDocVw.IWebBrowser2 wb = s.OLEFormat.Object as SHDocVw.IWebBrowser2;
                    object url = (object)"http://google.com/";
                    wb.Navigate2(url);
                } 
            }
        }
    }

The page is refreshed correctly. However, what is different now is that the page is automatically zoomed-out, so the page fits inside the control. Even if I make the control smaller, the page gets zoomed-out even more, to fit inside it.

I've solved this problem by creating a custom User Control, and inserting a WebControl into it. Then, I've made the control "COM Visible", and thus, I can include it flawlessly inside PowerPoint, by using its ProgId.

That's because you change all the shapes on the slide into that control including the slide itself. You need to add a way to differentiate between your control and other controls. Just checking if something is, has an OLE control object is not sufficient.
