Hi folks,
I'm attempting to use Tk::Text, and looking for a way to get it to tell me when it's contents have changed. Unless I'm reading the docs wrong, then binding a callback to the <<Modified>> virtual event should do the trick, however, this appears to either not run my callback at all, or only do it once. Test code: 
use warnings;
use strict;

use Tk;

my $MW = MainWindow->new(-title => "Tk::Text test",
                         -width => 200,
                         -height => 200);

my $text = $MW->Text(-height => 10,
                     -width  => 40,
                     -wrap   => 'word');
$text->pack(-side => 'top', -fill => 'both');

$text->bind('<<Modified>>' =>
            sub { getText($text, @_) } );

MainLoop;

sub getText
{
    my ($t, @args) = @_;

    my $text = $t->get('0.0', 'end');

    print "Got: $text\n";

    return if(!$text);

    return 1;
}

If I run this, and type in the text box, I only get a "Got: x" for the first letter I type, the rest of them seem to get ignored. In my real code, it doesnt seem to get called at all.

I'm probably going to work around this by binding to <FocusOut> instead, but its still strange and annoying.. Or am I misinterpreting the docs?
