double-clic / file : targetting an already open Scilab session

[Samuel GOUGEON]

  Hello,

I would like to run some files into _an_already_open_ Scilab session
just by double-clicking on them.
After having declared the new file type (for Windows XP),
double-clicking on a proper file runs it through a _new_ Scilab
session.
I have not found neither through Windows options, nor through
Scilab's command line launching options, how to target an already
existing session.
Is there a way that i have missed, to do that ?

Thank you
Samuel
