Ah! Yes, `hl-line-mode' is part of Emacs.  It is a buffer-local minor
mode that highlights the line where point is in.  It is implemented
with an overlay.

Yes, that face is also used for mouse-highlighting in some places, for
example in *Help* buffers.

Unless you know more than you told, I would think that this conclusion
is premature.  Maybe there is something going wrong in your setup and
we should figure out what it is.

If I understand you correctly, you have a light background and a dark
foreground for the default face and a dark background and a light
foreground for the highlight face.  You said that in some cases the
dark background of the highlight face does not take effect.  Is that
/everywhere/, where a face other than the default face is in the
buffer?  Or does this apply only for a few faces?  Or only in some
modes?  If the latter: which mode?  

If the former: you can examine the text properties a point with M-x
list-text-properties-at (assuming you are using a released version of
Emacs 21).  Please post that together with a description of what you
see.

Finally, can you reproduce the behaviour you described starting from
emacs -q --no-site-file? Can you set up a small test case so that I can
reproduce that behaviour?

FYI, hl-line-mode works as expected here.
