Ola Hansson et al, NN4.x breaks with CSS sheets when they use relative or absolute font-size references (the letters get very small and difficult to read). And if CSS is turned off for NN4.x, the font sizes "normalize" but page formatting (and other features) that rely on CSS breaks.
NN6 on Mac doesn't format the middle of the page very well either (it runs over the login box). Yet on NN4, there is a circa 25% width space between the login-box and the middle body text (with CSS active)! I will see if I can create a stable html version in the spirit of the current design...
