I should have mentioned that not only does the close program on sleep option work without any problems, I no longer need to use it as the program recovers after sleep without problems when using the DX9 version on both the computers :-)
I think that from my experience the recommendation of Open GL for most users could be a bit optimistic, especially when I have had problems using the Open GL version on a computer with the AMD Radion HD 6310M which would appear to come into the Radion HD2xxx - HD8xxx group that you specifically recommend the Open GL version for. Perhaps it would be better to suggest using the DX9 version first, as I think first impressions would be better with that, and then suggest that the Open GL version could be tried to see if it improves performance. Any problems would then be more obvious having seen how the program should behave while using the DX9 version.
