Thanks for the answer. I am using context version 2003.1.31, and I have changed the code a little according to your suggestion. However, everything remains blue. The problem seems to appear when the text to be highlighted gets a bit more inolved. Below is a complete sample that shows the effect 'nicely' -- the second page has blue-gray background except the page numbers, but the text is highligthed in red correctly. I still fear that I am missing the crucial point.

Then $b=b1=b(ac)=(ba)c=c$. \starttheorem Here are a few blurps: \startitemize[n] \item $(\R^+,1,\cdot)$ or $(\Q^+,1,\cdot)$ or $(\Q -\{0\},1,\cdot)$ \item $\R,0,+)$ or $(\Z,0,+)$ \item Let $B$ be the set of polynomials of degree $n$, and $1$ the constant polynomial with value $0$, and the multiplication given by polynomial addition. \item Let $S$ be a set, and $B$ be the set of selfmaps of $S$ which are one-to-one. If the set $S$ is finite, these are called permutations. Let $1$ be the the identity map, and $\cdot$ be the composition of the maps. \stopitemize \stoptheorem And another little theorem: \starttheorem Let $B$ be a group and $C$ a subset of $B$ such that \startitemize[n] \item $1\in C$. \item For all $a\in C$ also $a^{-1}\in C$. \item For all $a,b\in C$ also $a b$ and $b a \in C$. \stopitemize Then $C$ is also a blurps, and it is called a subblurps of $B$. \stoptheorem We have to check that $C$ satisfies all the axioms of a blurp. But this is clear, as the existence of the fidelity element and the surverse elements are guaranteed by the theorem, and all identities are already true in $B$. \starttheorem Let $B$ be a group and $C$ a subset of $B$ such that \startitemize[n] \item $1\in C$. \item For all $a\in C$ also $a^{-1}\in C$. \item For all $a,b\in C$ also $a b$ and $b a \in C$. \stopitemize Then $C$ is also a blurps, and it is called a subblurps of $B$. \stoptheorem \stoptext On Tuesday, July 29, 2003, at 12:02 PM, Hans Hagen wrote:

the text comes out green all right, but the blue background is smeared all over two pages. I have tried a few modifications to no avail, so I fear I am doing it all wrong.

What version do you use? (take the latest)

looks ok here, that is, when you add:

before=\blank, after=\blank,

to the deifnition of the background

[of play with the offsets]

Curiously, when I typeset the above th first time, I only get the green text (no blue), and the mess shows only up when typesetting the second time.

normally texexec should handle that for you (multiple runs are needed to sort out the background)

Thanks Patrick, your version looks indeed as I intended. My second page is very different. This most likely means that Hans' question about the version I am using was to the point. I go and see that I get my TeX installation updated (does somebody know how to do that most efficiently in Mac OS X? ). Thanks again, this is most helpful.

Your file looks fine here. I have put my result on http://levana.de/tmp/test.pdf for a short time. Perhaps you could comment on it?

Not needed. MacOS X can run Perl, shell and Ruby scripts, too.

[btw, the next version of texshop will have context specific menus]

As a little update: I tried to install the context package from http://www.pragma-ade.com/context/cont-tmf.ziphttp://www.pragma-ade.com/context/cont-tmf.zip

into /sw/share/ of the fink distribution both by replacing the corresponding directories and by adding the files into the corresponding directories. Both approaches break the context installation. For those interested, the log file is below.

I give up for today . Matthias

btw: Somebody with first name Helmut sent me a direct reply, asking about rounded corners. Tried that too without luck. I can't reply to Helmut directly, as his email has my own address as the only return address. Scary.

did you (1) run mktexlsr (2) run texexec --make --alone (1) -> tells tex where to find files (2) -> makes a new format file currently you have a conflicting system i.e. format file does not match some run time files Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

I have been thinking about (and have had requests for) a ConTeXt-update i-Package, given that I am going to use ConTeXt and that ConTeXt changes rather frequently compared to teTeX's texmf tree. Hans, can you mail me off list what actions are needed to install the current ConTeXt in th eteTeX texmf tree? G -- "To be or not to be, that is the question" -- Parmenides

Gerben, that would be wonderful. I always shy away from upgrading because it might break things and takes time. If your i-installer does the job, that would be a major advance. So please, go for it!

I can only agree - please! Matthias

Start i-Installer, open the ConTeXt updater i-Package from Known Packages. Hit configure. G -- "To be or not to be, that is the question" -- Parmenides
