Right, but the fix Andrew posted should work because the offending code 
is the code he's fixing, and is called after all of the other color 
types.  I don't have a moment to install and test it, but I know that 
when I added an exit before this little offending routine, everything 
including the build dialog in Lazarus was fixed.

I've got to run back to church and in another couple of hours will 
install the fix as suggested and test all the cases I've seen, which 
include the Lazarus build dialog, drawing on canvas with standard system 
related colors, and the TStaticText control.

But what you've mentioned does explain why form backgrounds and others 
would display correctly instead of black and may be an entirely separate 
yet related issue.

Thanks,
