Never mind, there's a 'backspace=0cm' to be set.

Dear List,

The following example results in a pdf that has a wide margin on both sides despite the \setuplayout :

    \showframe
    \setuppapersize[A4][A4]
    \setuplayout[margin=0cm, edge=0cm, margindistance=0cm, edgedistance=0cm]
    \starttext
    hello world
    \stoptext

Does anyone know how to really set the paper margin?

Thanks!

Best,
Sylvain
