Hi All, I wonder if you can help: I have been having a problem with \startcolumnsetspan when I was trying to create a magazine layout for a Uk psychodrama organisation. Out of curiosity ( and in the hope i might learn something) i turned on tracing for a short example that gives the problem here is the source of the test. \setuppapersize[A4][A4] \definecolumnset[columntest][n=3]% \definecolumnsetspan[wide][n=2]% \starttext \startcolumnset[columntest] \input knuth \tracingall \startcolumnsetspan[wide] \dorecurse{3}{\input knuth\par} \stopcolumnsetspan \dorecurse{10}{\input knuth\par} \stopcolumnset \stoptext of course it spewed out a huge log file but when looking at it i found this: \dostartcolumnsetspan [#1][#2][#3]->\endgraf \vskip \zeropoint \bgroup \forgetall \ifnum \columnsetlevel >\zerocount \else \columnsetspanhsize \hsize \nofcolumns \plusone \mofcolumns \plusone \fi \setupframedtexts [cs:#1] [\c!width =\columnsetspanhsize , \c!linecorrection =\v!off , \c!depthcorrection =\v!off , #2]\!!countc \namedframedtextparameter {cs:#1}\c!n \!!countd \nofcolumns \ifnum \!!countc >\!!countd \!!countc \!!countd \fi \advance \!!countd -\mofcolumns \advance \!!countd \plusone \doif {\namedframedtextparameter {cs:#1}\c!alternative }\v!a {\ifnum \!!countc >\!!countd \!!countc \!!countd \fi }\setcolumnsetspanhsize \mofcolumns \!!countc \hsize \columnsetspanhsize \setbox \scratchbox \vbox \bgroup \dostartframedtext [cs:#1][\v!none ]\ifnum \columnsetlevel >\zerocount \namedframedtextparameter {cs:#1}\c!before \fi \unexpanded \def \stopcolumnsetspan {\dostopcolumnsetspan {#1}} #1<-wide #2<- #3<- {\par} Lua linebreak_filter failed, reverting to default on line 9 Any ideas? my actual document exhibits the same sort of fault. It used to work before I had to update the minimals ( some time ago) when I moved to another computer and it failed then. I must say I really like context and appreciate all the hard work that must have gone into it. I know that it is a large system and will take me some time to get to grips with. Any help would be appreciated. Cheers Gordon
