[NTG-context] \blank[] doesn't work when nothing precedes it

Dear List, I'm trying to put the document title at around .25\paperheight by inserting a \blank: \setuplayout[topspace=0cm, header=0cm, height=\paperheight] \starttext \blank[.25\paperheight] foo \stoptext But the "foo" still appears at the very top. Does anyone know why it behaves like that, or whether there is a more authentic way to put the first word at .25\paperwidth than inserting a tiny invisible space before the \blank? Thanks! Best, Sylvain
