For reference, I tried everything I could think of to get rid of the nVidia Control Panel and it doesn't appear possible. On Windows 7 it installs as part of both the default driver pack that came with my computer and the nVidia downloaded updates. I can remove the nVidia Control Panel from Windows Control Panel but that has no effect on how the driver behaves with the white text on 3D HUD problem.
Also, I notice lately that after a few restarts of Metabolt, the white text itself will virtually disappear and become thin and almost transparent. Completely unviewable on the HUD.
