This is because (I think) that tikzpicture does not return a box.

    {\hbox{\input \jobname-tikz.tmp\relax}}

I have noticed this \placefigure and I do not know if it is a bug or a 
feature. \placefigure expects you to give a box as a figure. Compare 
the output of

   {Left Fulushed}
   {This is a test}


   {\hbox{This is a test}}

Hans, will adding a \hbox explicitly to \placefigure break anything?

You will need to install tikz from 
(http://sourceforge.net/projects/pgf/). The directory is not TDS 
complaint, so you may need to correct that before installing the tree.

And of course, ignore Till Tantau's comments about ConTeXt on page 
67-68 of the manual. He was working with stone age ConTeXt and still 
manged to get the whole thing working :-)

And whenever you decide to overhaul the input mechanism for metapost, 
tikz has some nice ideas.
