[NTG-context] Problem with \setuplayout parameters being ignored

[Keith McKay]

Hi

I'm having a strange problem with the \setuplayout command with the 
parameters being ignored. In the code below the only parameter which 
does get setup is the backspace parameter, the header, footer, width, 
and margin parameters are setup differently according to the log. I'm 
probably missing something fairly obvious so hints would be helpful. The 
document I'm trying to setup will probably be a maximum of 50 pages and 
I would like to reduce the space at the top and bottom of the page.

Best Wishes
