Hans et al,
When we discovered that \column doesn't work reliably with
\startcolumns[n=2] ... \stopcolumns, we made some changes to our
style files:
%\setupcolumns
% [tolerance=stretch,
% balance=yes,
% blank=flexible,
% rule=off,
% distance=2.5em]
\definecolumnset[exercises][n=2]
\setupcolumnset
[exercises]
[distance=2.5em,
balance=yes]
\definecolumnset[answers][n=2]
\setupcolumnset
[answers]
[distance=2.5em,
balance=yes]
%\def\startquestions{\exercises{Exercises}\startcolumns[n=2]}
%\def\stopquestions{\stopcolumns}
\def\startquestions{\exercises{Exercises}\startcolumnset[exercises]}
\def\stopquestions{\stopcolumnset}
%\def\placeanswers{%
% \bgroup
% \doifmodeelse{short}
% {
% \keepblocks[shortsubanswer,longsubanswer]
% \answers{Answers}\vskip 1em\startcolumns[n=2]
% \selectblocks[shortanswer][criterium=section]
% \stopcolumns
% }
% {
% \keepblocks[shortsubanswer,longsubanswer]
% \answers{Solutions}\vskip 1em
% \selectblocks[longanswer][criterium=section]
% }
% \egroup
%}
\def\placeanswers{%
\bgroup
\doifmodeelse{short}
{
\keepblocks[shortsubanswer,longsubanswer]
\answers{Answers}\vskip 1em\startcolumnset[answers]
\selectblocks[shortanswer][criterium=section]
\stopcolumnset
}
{
\keepblocks[shortsubanswer,longsubanswer]
\answers{Solutions}\vskip 1em
\selectblocks[longanswer][criterium=section]
}
\egroup
}
We can now no longer compile what we could formerly compile:
systems : end file chapter0/equations at line 77
systems : begin file chapter0/equationsexercises at line 79
(../chapter0/equationsexercises.tex
system : module newmat (line 31) already loaded
system : module math=ext (line 32) already loaded
system : module fig-base (line 33) already loaded

l.104 \setnumber

If I go into the offending file and comment out the line:
\startquestions
%\setnumber[page]{\pagenumberExercisesOneTwo}
Compiling again:

?
We are at a complete loss of what to do.
