Wisest monks,
   When I run the following (very) short code, an awkward error comes up. Does anyone have an idea where it can come from ? I'm pretty sure this is a record of the longest possible error for the shortest possible code, even though this wasn't my aim :-)

#!/usr/bin/perl

use strict;

use Win32;
use Win32::GUI;
[download]

And here's the error :

Heureux qui, comme Ulysse, a fait un beau voyage
Ou comme celui-là qui conquit la Toison,
Et puis est retourné plein d'usage et raison,
Vivre entre ses parents le reste de son âge!
