The display is only 1 bpp (i.e. no grey scale at all) with a very simple
controller. The palette can't be changed. The spftware driver's palette is
0=Black & 1=White which is the same as the haedware controller. Even if the
software palette is incorrect, I should be able to force it to something
else. However, I can't.
Only the client area of the browser behaves this way. It's as if the
background color were initalized to zero/black prior to entering a case
statement based upon bpp, but there's no 1 bpp case. So it falls through
maintaining it's black initialized setting.
Thanks for your help.
