Sorry, I forget to mention that I use wxPerl as shown in the code. In my code snippet, I have not included the module that uses the wxHtmlWindow to make the code simpler.

The PAR::PACKER problem seems to do with the "use wxHtmlWindow" regardless of whether I include the actual module or not.

Here is the code for wxHtmlWindow:

use Wx::Html;

package wxHtmlWindow;

use strict;
use base qw(Wx::Panel);

use Wx qw(:sizer);
use Wx::Event qw)EVT_BUTTON);
 
sub new {
  my $class = shift;
  my $this = $class->SUPER::new( $_[0], -1 );

  my $html = $this->{HTML} = wxHtmlWindow::Derived->new( $this, -1 );
  my $top_sizer = Wx::BoxSizer->new( wxVERTICAL );

  my $but_sizer = Wx::BoxSizer->new( wxHORIZONTAL );
  my $print = Wx::Button->new( $this, -1, 'Print' );
  my $forward = Wx::Button->new( $this, -1, 'Forward' );
  my $back = Wx::Button->new( $this, -1, 'Back' );
  my $preview = Wx::Button->new( $this, -1, 'View' );
  #my $pages = Wx::Button->new( $this, -1, 'Page Setup' );  

  $but_sizer->Add( $back );
  $but_sizer->Add( $forward );
  $but_sizer->Add( $preview );
  $but_sizer->Add( $print );
  #$but_sizer->Add( $pages );

  $top_sizer->Add( $html, 1, wxGROW|wxALL, 5 );
  $top_sizer->Add( $but_sizer, 0, wxALL, 5 );

  $this->SetSizer( $top_sizer );
  $this->SetAutoLayout( 1 );

  EVT_BUTTON( $this, $print, \&OnPrint );
  EVT_BUTTON( $this, $preview, \&OnPreview );
  EVT_BUTTON( $this, $forward, \&OnForward );
  EVT_BUTTON( $this, $back, \&OnBack );
  #EVT_BUTTON( $this, $pages, \&OnPageSetup );

  $this->{PRINTER} = Wx::HtmlEasyPrinting->new( 'ZTC GUI' );

  return $this;
}

sub html { $_[0]->{HTML} }
sub printer { $_[0]->{PRINTER} }

sub OnPrint {
  my( $this, $event ) = @_;

  $this->printer->PrintFile( $this->html->GetOpenedPage );
}

#sub OnPageSetup {
#  my $this = shift;
#
#  $this->printer->PageSetup();
#}

sub OnPrinterSetup {
  my $this = shift;

  $this->printer->PrinterSetup();
}

sub OnPreview {
  my( $this, $event ) = @_;

  $this->printer->PreviewFile( $this->html->GetOpenedPage );
}

sub OnForward {
  my( $this, $event ) = @_;

  $this->html->HistoryForward();
}

sub OnBack {
  my( $this, $event ) = @_;

  $this->html->HistoryBack();
}

package wxHtmlWindow::Derived;

use strict;
use base qw(Wx::HtmlWindow);

sub new {
  my $class = shift;
  my $this = $class->SUPER::new( @_ );

  $this->LoadPage( 'files/index.html' ); # in /files folder
  #print $this->ToText, "\n";

  return $this;
}

sub OnLinkClicked {
  my( $this, $link ) = @_;

  Wx::LogMessage( 'Link clicked: href="%s"', $link->GetHref() );
  $this->SUPER::OnLinkClicked( $link );
}

I think I have created some confusion here. It might be clearer if I change the title to Wx::Html causes exe to crash after PAR::PACKER.

Basically replace everything to do with wxHtmlWindow by Wx::Html in my previous appends and the problem remains the same.

Sorry about the confusion. My fault.
