Hi Hans,
If I do this, the problem remains the same.

\starttikzpicture
  \vbox{\matrix [matrix of math nodes,ampersand replacement=\&]
  {
    a_8 \& a_1 \& a_6         \\
    a_3 \& a_5 \& |[red]| a_7 \\
    a_4 \& a_9 \&     a_2     \\
  };}
\stoptikzpicture

        Hello,
        Everything is in the title, as this example shows.


    normally it means that you need to wrap in a \vbox{...}

        Thanks,
