Hello, I'm trying to duplicate the functionality of the tabbed thumbnails in Windows 7 in my own WPF application that runs in Windows 7. THe thumbnails update while the application is running and not in a minimized state, and appear to some how updates while the window is minimized if the thumbnail is relaunched. Is there any way, using the API code pack that I access these thumbnails, or some how duplicate this functionality? I tried using the TabbedThumbnailScreenCapture class in the the Microsoft.WindwosAPICodePack.Taskbar namespace, but when I try and grab the thumbnail after minimizing the window, all I get is a small white rectangle that doesn't display the contents of the window. Thanks!
