Environments not Loading

Am having issues getting Environment Backgrounds to show using the standard Rhino Rendered setting. When I switch to Raytrace with Neon the Environment background shows. This is a new PC which has a Quadro 5200. Ive updated the drivers to drive361.75 with no luck. I guess part of the question would be what Drivers are users with a Quadro 5200 using?
Other rendering plugins are NVIDIA IRay, Flamingo, Brazil with Neon.
Are any others seeing this issue?7
