High/inverse is really a bridge feature to be used as a "blank slate"
theming component so that the theming does not interfere with A.T.
features such as Joseph's magnifier settings. Please feel free to
comment on list or file bugs if you have issues/suggestions,
especially if you use it in conjunction with the magnifier or other
A.T. devices. This setting has not been improved yet, and is still
very incomplete. It should work reasonably well for text. As you say,
though, it doesn't affect text on webpages.

Best wishes,
Meg Ford
