Julian Stahnke 17 December 2006 Noticed that as well. Seems as if sub-pixel anti-aliasing is turned off when using drop shadows. You can try and turn it off manually in the ‘appearance’ pane in the system preferences by setting the anti-aliasing mode to ‘best for CRT’. The result is that all light text on dark background looks thinner. Normal text looks worse, though. Apparently, this will improve in the future. Firefox 3 and the new Camino dev version use Cairo which somehow manages to display the text better even with sub-pixel anti-aliasing turned on. See here for an example: Hickdesign: Cairo beats Safari?.
