Hello Monks,

Perl: Strawberry Perl 5.18 (*on Windows XP)

A few months ago I wrote a very large GUI program using Perl Gtk2 which still seems to be working just fine. But I'm now
creating a MUCH smaller GUI script that I really just want to display a Popup window to ask the User Yes Or No. If they select
"No" then the script SHOULD exit. I don't remember ever having this issue in my last GUI program, but it was a while ago now and
I'm pretty confused by this error, and why the script won't exit.

Here is my Gtk2 code. At first I just created a MessageDialog object with 'undef' as its parent but I was getting errors. The error
wasn't specifically towards the parent window, but I decided to create a $window object (*toplevel) anyway and I just don't ever
issue the "->show_all" function to display it...
#!/usr/bin/perl

use strict;
use warnings;
use Gtk2 -init;
use Glib qw/TRUE FALSE/;


my $window = Gtk2::Window->new('toplevel');
$window->signal_connect(destroy => sub {Gtk2->main_quit;}); #<---ERROR
### $window->show_all;

my $msg_dialog = Gtk2::MessageDialog->new_with_markup($window, 'modal'
+, 'error', 'yes-no', "Would you like to retry the connection?");
$msg_dialog->set_title("No Connection Found");
$msg_dialog->set_destroy_with_parent(TRUE);
$msg_dialog->signal_connect (response => 
sub {
    my ($self, $response) = @_;
    if ($response eq 'yes') {
        $msg_dialog->hide();
        my_function("yes");

    } elsif ($response eq 'no') {
        $msg_dialog->destroy();
        $window->destroy;
    }
});

$msg_dialog->run();

Gtk2->main;
0;

So when I execute the script, the MessageDialog opens just fine and I click the "No" button and I get the following error:

Gtk-CRITICAL **: gtk_main_quit: assertion `main_loops != NULL' failed at C:\Documents and Settings\Administrator\My Documents \test_gtk.pl line 10.

Also, when the error gets displayed in the console window, the script basically just hangs until I do a Ctrl-C...

Anyone have any idea why this isn't working, am I missing something here?
Any thoughts or suggestions would be much appreciated, I'm not sure what else to try.

Thanks in Advance,
Matt
