I am writing a POE::Component::DirWatch integrated with a SystemTray::Applet. The callback in SystemTray::Applet runs the POE script. I think in order for the actual icon to get created, the callback has to return. But since my callback will not return, no icon is created. How do I get around that one?

#!perl
use warnings;
use strict;
use Data::Dumper;
use Win32::Process;
use File::Slurp;
use SystemTray::Applet;
use POE; # auto-includes POE::Kernel and POE::Session
use POE::Component::DirWatch;

my $user = "mwb";

my $app = SystemTray::Applet->new(
  text     => 'Candela Dashboard',
  icon     => 'C:\Documents and Settings\Mike\Desktop\Candela\dashboar
+d.ico',
  callback => &poe_dir_watcher,
  immediate => 1,
);

sub poe_dir_watcher {

    POE::Session->create(
        inline_states => {
            _start => sub { $_[KERNEL]->yield("next") },
            next   => sub {
                print "tick...\n";
                $_[KERNEL]->delay(next => 1);
            },
        },
    );

    my $watcher = POE::Component::DirWatch->new(
        alias         => 'dirwatch',
        directory     => 'V:',
        file_callback => sub{ load_crm($_[0]) },
        interval      => 1,
    );

    POE::Kernel->run();

    return;
}

sub load_crm {
  my ($file) = @_;
  my @data;
  if ($file =~ /$user/) {
    my @data = read_file("$file");
    chomp @data;
 
    # replace ^ with |
    for (2..4) {
      ($data[$_] = $data[$_]) =~ s/\^/|/g;
    }

    my $result = run_firefox(\@data);
    unlink($file) if $result;
  } 
}

sub run_firefox {
  my ($data) = @_;
  my $firefox = 'C:\Program Files\Mozilla Firefox\firefox.exe';
  my $crm_url = "firefox http://ext-test.candelacorp.com/crm/nomo.pl" 
+. 
    "?cust_num=" . $data->[0] . 
    "&cont_num=" . $data->[1] . 
    "&prod_num=" . $data->[2] .
    "&prod_qty=" . $data->[3] .
    "&prod_prc=" . $data->[4]
  ;
  print $crm_url, "\n";
  Win32::Process::Create(
    my $ProcessObj,
    $firefox,
    $crm_url,
    0,
    NORMAL_PRIORITY_CLASS,
    "."
  ) || die ErrorReport();

  return 1;
}

sub ErrorReport{
  print Win32::FormatMessage( Win32::GetLastError() );
}
