Certain computers with 3D sound cards will also require that you use alt tab to bring the Virtual ISS window to the front. For other trouble shooting and support, try the Unrealty Support Forums. If you double click on the left mouse button, the information mode will be activated. If you inadvertently double click on the left mouse button and put the VISS in the information mode, press the escape key to get back to the navigation mode. The VISS defaults to software rendering in 640x480 resolution.
Software rendering works well on a broad range of computers and is very reliable.
You can also adjust the resolution, color bits, detail, brightness and other parameters. The VISS has built into it a full collaborative capability for exploring the ISS along with other VISS users across the Internet. At the time of initial release, the collaborative capabilities have not been thoroughly tested. Check this web page for updates on this feature.
