I have some trouble to draw lines between nodes using my own node
formats.

If I draw some lines between the nodes using a command like the one
I've inserted in the example above, the lines ends are inside the
box and not outside the enclosing box. I think it's due to the fact
the \psshadowbox command is enclosing the \rnodes commands and not the
reversed. I've tried to replace

   \psshadowbox[linecolor=red]{\rnode at iii\Rnode at ii{\psm at thenode}}}

with

   \rnode at iii\Rnode at ii{\psshadowbox[linecolor=red]{\psm at thenode}}}

but without success.

Do you have any suggestion?

Chris
