The solution to this problem is to add the text in the window to screen with a custom program that I've installed to create a custom window image. (I recommend Photoshop.) In Adobe Reader the file contains a specific “Window Image” field, to get this, please enter a name for it “Window Image.png”. And to save the image, please select it in the “save image data” dialog. When I am using it in Internet Explorer, the screenshot is not visible. If your application requires a lot of screenshots, please see this example on how to use it. If you are going to have more than the minimum number of documents in your application, please see this example.
