Hi everybody.

I am experimenting with ConTeXt and columns. I am creating a simple 
style and I setup 3 columns and redefined some heading (section, 
subsection, subsubsections).

Now the problem is that the text at the end of the columns is not 
aligned (i.e., the columns end at different heights).

I thought that this was due to the \blank commands that I specified as 
before and after parameters in the heading definitions, but even by 
using the flexible modifier doesn't change that behavior.

I don't know where the problem is. The tex file is attached.

Thank you,
Fabio

P.S.: By using the attached file, I cannot specify the position 
parameter for \placefigure. If I write 
\placefigure{Name}{\externalfigure[...} it works. 
\placefigure[btlr]{name}{\externalfigure[...} does not. Weird.

P.P.S.: I was reading the columns.pdf "tutorial". I saw that a 
\definecolumnsethsize command is used but I haven't found any 
documentation about that command anywhere. I use width=2\textwidth which 
seems to produce the same effects (2 columns span).
