Greetings PerlMonks

I have this simple script; 
#! c:/perl/bin/perl.exe
#
#

use strict;
use warnings 'all';


system (CLS);
my $vu_win = MainWindow->new();
$vu_win->configure(-title=>'Verify User', -background=>'blue');
$vu_win->geometry('+100+300');

my $vu_frm1 = $vu_win->Frame(-relief=>'groove', -borderwidth=>3, -back
+ground=>'blue',)->pack(-side=>'top', -fill=>'x');
my $vu_lb1 = $vu_frm1->Label(-text=>'Enter Username',-background=>'blu
+e',-foreground=>'white',)->pack(-side=>'left');
my $vu_en1 = $vu_frm1->Entry(-textvariable=> \my $usr, -width=>35, -ba
+ckground=>'white')->pack(-side=>'left', -pady=>5);

my $vu_frm2 = $vu_win->Frame(-relief=>'groove', -borderwidth=>3, -back
+ground=>'blue',)->pack(-side=>'top', -fill=>'x');
my $vu_lb2 = $vu_frm2->Label(-text=>'Enter Password',-background=>'blu
+e',-foreground=>'white',)->pack(-side=>'left');
my $vu_en2 = $vu_frm2->Entry(-textvariable=> \my $pw, -show=>'*',-widt
+h=>35, -background=>'white')->pack(-side=>'left', -pady=>5);

$vu_en2->bind('<Return>'=> sub{ &process( $usr, $pw ), $vu_win->destro
+y});

sub process
{
    my ($usr_name, $pass_wd) = @_;
    $vu_win->destroy;
    print "\n$usr_name, $pass_wd\n";
}

MainLoop();

But when I run it I get the following output! 
tsx14528, bncfvbncvbncvbncv
destroy (1):

SV = PVMG(0x34878e4) at 0x182e30c
  REFCNT = 5
  FLAGS = (PADBUSY,PADMY,GMG,SMG,RMG,ROK)
  IV = 0
  NV = 0
  RV = 0x36b1c40
  PV = 0x36b1c40 ""
  CUR = 0
  LEN = 0
  MAGIC = 0x36c791c
    MG_VIRTUAL = 0x3b86340
    MG_TYPE = PERL_MAGIC_ext(~)
    MG_FLAGS = 0x02

    MG_OBJ = 0x36c059c
        SV = PV(0x367fb94) at 0x36c059c

          CUR = 0

Would it be possible for you please:

to advice on the reasons for this output when I expect nothing but two strings ($usr_name, $pass_wd) to be displayed!

Any perls of wisdom would be highly appreciated!
