GTViewer 7.0 has been certified on Windows Vista. No changes were required to make GTViewer compatible with Windows Vista, so older versions should also run without compatibility issues. While there is no functionality in GTViewer specific to Windows Vista, you will notice the Windows Aero enhanced display. For example, GTViewer’s title bar will have the semi-transparent appearance as well as the other dialog box titles and borders. You will also notice other cool features such as the Windows Flip and Windows Flip 3D Animation.
