Hi Wolfgang,
I modified the example (hopefully in a meaningful manner). I get the desired
output with the old beta, but it still fails with todays beta.
\setuplayout [width=middle,height=middle,header=0pt,footer=0pt]
\definelayout[first] [header=2cm]
\definelayout[last] [footer=2cm]
\definelayout[current]
\starttext \showframe % \checkcurrentlayout
% \dorecurse{2}{test\page} % last is wrong
\dorecurse{5}{test\page} % page 2 and „last“ are wrong
\stoptext
Andreas
