Please bear in mind you have a mature product that is not supported by Windows 8. Intel did not develop drivers for your graphics controller running Windows 8. See the following FAQ:
first and foremost - thank you for the swift reply. That is indeed unfortunate, but as far as I can see due more to a political decision than a technical constraint. Would it be possible for you to provide us with a direct e-mail to the team in charge of legacy support, so that we may at least petition for a change of Intel's stance on this particular topic?
Furthermore, your reply seems to suggest that the drivers for Windows 7 is indeed still being maintained. Any ETA on the next driver update for Windows 7? One could hope that such a driver update could improve the current situation on Windows 8.
