[NTG-context] Setuphead issue!

Hi, I'm a bit puzzled by the mkiv /setuphead/ command of ConTeXt! The space *before* and *after* the /subject/ command can usually be set by the *before* and *after* arguments of the /setuphead/ command. Now I'd like to have _no vertical space_ before and after the header. I've tried just that by setting either *before=* and *after=* and *before=\blank[none]* and *after=\blank[none]*. But none of these seem to work. Any idea? Gerard --
