The example was:
http://cvs.sourceforge.net/viewcvs.py/gtk2-perl/gtk2-perl/tutorial-examples/progressbar.pl

I just went back to have a look and the 5 or 6 scripts I randomly
selected all use it.

I guess they must be using old deprecated methods. It explains the weird
looking:

my $pdata = {};
$pdata->{WINDOW} = Gtk2::Window->new('toplevel');
$pdata->{WINDOW}->resizable(TRUE);

and why when I tried Gtk2->init; I got:

Can't locate object method "resizable" via package "Gtk2::Window"

Thanks for the help.
