this is a nice little processor, i didn't know about it.
it might be obvious, but does your file include the dashed lines? if  
so, try leaving them out.

for me the following worked (pretty straightforward):

1> curl -s ftp://cam.ctan.org/tex-archive/support/flow.tar.gz | tar  
xvzf -
flow/
flow/README
flow/flow.c
flow/flowdoc.tex
flow/flowdoc.pdf
flow/COPYING

2> cd flow/
3> gcc -o flow flow.c

4> cat > box.flo
Right
Box
   This is
   the first
   box.
Box 8 1
   And this is the second
^C

5> ./flow box.flo
\begin{picture}(13.000000,2.000000)(0.000000,-2.000000)
% picture environment flowchart generated by flow 0.99e
\put(0.0000,-2.0000){\framebox(4.0000,2.0000)[c]{\shortstack[c]{
This is\\
the first\\
box.
}}}
\put(4.0000,-1.0000){\vector(1,0){1.0000}}
\put(5.0000,-1.5000){\framebox(8.0000,1.0000)[c]{\shortstack[c]{
And this is the second
}}}
\end{picture}

cheers,
