Create a test with  step that captures the browser state. When executed against some websites in IE the image has blank content. The same test executed against other website capture the image successfully.

For example the following executed against Google.com captures a blank image:

            ActiveBrowser.NavigateTo("http://google.com/", true);
            System.Drawing.Bitmap brImg = null;
            brImg = ActiveBrowser.Capture();
            brImg.Save(@"C:\WebAiiLog\capture.jpg");

However the same code executed against bing.com works.
