Note: The current publicly available version of Windows 8 contains issues related to how the size of the windows is computed; more specifically, DwmGetWindowAttributes(hWnd, DWMWA_EXTENDED_FRAME_BOUNDS, …) does not always return the correct rectangle size. This will be fixed in the final version of Windows 8. Expect an update to Window Clippings as soon as the RTM version of Windows 8 gets public.
