[NTG-context] Bottomspace / Layout question!?

Hi there, I have a question regarding the spacing and margins of a text document. My layout is defined like this: \setuppapersize[A4][A4] \setuplayout[ topspace=1cm,header=1.5cm, backspace=3cm,cutspace=3cm, bottomspace=1cm,footer=1cm, margin=0cm ] Everything works like it is supposed to, except the "bottomspace" parameter, instead of 1cm I have 3.5cm from bottom footer to bottom rim of paper. Can anyone tell me what the problem is here? I tried a lot of other parameters, like bottom, or bottomdistance, etc. It seems ConText is ignoring my bottom definitions, what can I do to increase my textheight, or decrease my bottom height?
