Good evening.
Many thanks for your help. Your solution works well with the newest
ConTeXt and one particular document I now typeset. I have to check it
still with more documents. Do you want to gen a report from these tests?
If you want I can send you many examples, but not `minimal files',
since I don't know when the problem occures. As I typeset our church
bulletin, I've got that result pretty often---approximately on one
third or one fourth of all pages.
just test this on many docs and let me know if it fails
(one source of problems with i'm currently trying to catch is rounding
errors in comparisons)
I can't switch to columnset all my documents. Columnsets are
absolutely great (one of the ConTeXt miracle---I thought it is not
possible to do it in TeX because of its breaking routines), but
up-to-now columnsets cannot be ballanced (or can they?), and my church
bulletin is typset in such a way that each article can start anywhere
on the page, and the columns must be ballanced before it. I can't
explain it better because of my English, but its pages look like this:
x x
x x
x x
x x
Title of article
x x
x x
Therefore I would lobby for the support of the old \startcolumns ...
\stopcolumns environment. :-)
don't worry, i'm not driopping the old one, actually, in due time i'll provide more specialized ones and interfaces to write your own -)
balancing in columnsets is a tricky business, the following should work
(kind of manual balacing, complete control over how long columns on pages are; probably a bit fragile)

As for the Willi Egger's question, I don't use `fit' options very often.
The problem I've mentioned in my last mail occures even when the `width'
is set to some dimen and the `length' of page is set to some number of
lines.
Many greetings and thanks again.
Your sincerely

Hard to see without example. You may try this (i have this in my local
expermental setup)
\def\getmulticolumnlines
{\mcscratchdimen-\columntextoffset
\multiply\mcscratchdimen \plustwo
\advance\mcscratchdimen \columntextheight
\ifdim\precolumnboxheight>\zeropoint
\advance\mcscratchdimen -\precolumnboxheight
\fi
\settotalinsertionheight
\advance\mcscratchdimen -\totalinsertionheight
\getnoflines\mcscratchdimen
% added 30/7/2004
\ifnum\layoutlines>\zerocount \ifnum\noflines>\layoutlines
\noflines\layoutlines
\fi \fi
\nofcolumnlines\noflines}
Another option is to switch to column sets (see columns.pdf),

Re: [NTG-context] column balancing question
Good evening,
Though Hans has sent already a piece of code ...
I saw that you are using height=fit, and width=fit. Did you ever try to
compile your file without these options? -- Some time ago I experienced
troubles with such options, although my layout was different and the
document was not setup with columns.
Kind regards
Willi

One reason for me to switch to ConTeXt were its macros for typesetting

(I typeset almost all my documnts in two columns.) But I am not able to
supress one strange feature: some pages are one more line longer than
they should be. It happen randomly -- or at least I was not able to find
out when it happens. Therefore I'm not able to prepare an minimal file.
I thougth that setting
\widowpenalty=0
\clubpenalty=0
\brokenpenalty=0
\normalbottom
may help, but it does not.
Can you tell me how to fix this very problem? Well, it does so on all
versions of ConTeXt I have ever tried and both with teTeX and TeXLive
distribution.
Many thanks for your attention and help.
