Hi Paul, A sporadic problem sounds like a driver bug to me, so try different hardware and drivers to see if you can get a better handle on the problem. There is small chance that there is something on the OSG side that is invoking problems in the driver, but with such an indeterminate problem it's impossible to say how like this might be or what it might be. The best I could suggest on the OSG would be to try the svn/trunk version of the OSG is it's most up to date w.r.t bug fixes.
