I was using the demo with no problems. I've updated the demo to the new 10.3 beta and now I'm getting the top half of the screen showing the screen that was on there earlier. In other words, if I was looking at the outside of the plane and then changed my view to the cockpit, the upper half would still show the upper half of the outside of the plane view. Any ideas?

I do believe that's it. Thanks. I'll try the solution. I forced the vsync off and that seemed to fix it but I'll give this solution a try.

Thanks Mike, for the response, I just went to control panel and sure enough the override application was on. Is'nt now. LOL :-0

Happy to have helped guys. :)
