I am using the following code for a GUI in perl. In the case of buttons two clicks are needed for the action. how can i clear this??? Thanks in advance... My code is:

#!/usr/bin/perl -w
use strict;
use warnings;
use Win32::GUI qw(CW_USEDEFAULT);
use Win32::GUI::BitmapInline();
use Win32::Process;
use Win32;
my $ss;
my $DOS = Win32::GUI::GetPerlWindow();
Win32::GUI::Hide($DOS);
my $mw = Win32::GUI::Window->new(
    -title => "Test",
    -left => CW_USEDEFAULT,
    -size => [500,500],
    -color => 0x80FFFF,
);

$mw->Animate(
        -show => !$mw->IsVisible(),
        -activate => 1,
        -animation => 'center',
        #-direction => $d,
        -time => 500,
        
    );

$mw->AddButton(
    -text => "Start",
    -left => $mw->Width() - 480,
    -top  => $mw->Height() - 480,
    -size => [75,30],
    -onClick => \&fun2,
);
    $mw->AddButton(
    -text => "End",
    -left => $mw->Width() - 400,
    -top  => $mw->Height() - 480,
    -size => [75,30],
    -onClick => \&fun12,
);
$mw->AddButton(
    -text => "Process",
    -left => $mw->Width() - 320,
    -top  => $mw->Height() - 480,
    -size => [75,30],
    -onClick => \&fun1,
);
$mw->AddButton(
    -text => "Printer List",
    -left => $mw->Width() - 240,
    -top  => $mw->Height() - 480,
    -size => [75,30],
    -onClick => \&funp,
);

$mw->Show();
Win32::GUI::Dialog();
$mw->Hide();
