Have you noticed that when Windows Vista prompts you to allow a program to take action, that the screen blacks out? This is to show you that you are moving to an elevated desktop - where you will allow the program to continue. This can be annoying but you can disable this feature.
Please Note: This guide involves the use of the Group Policy Editor, which is not included with Vista Home Premium/Basic or Windows XP Home. There is a workaround using the registry editor included. Please follow this workaround if you use any of the above operating systems. If this is the first time you are using the Group Policy Editor, read this guide.
