Hello monks, I am trying to use the fileevent feature of Perl/Tk under Win32.
My test code is the following: 
#!/usr/bin/perl
use strict;
use Tk;
use IO;
use IO::Socket::INET;
my ($server, $server_port, $maxlisten);
$maxlisten=5;

if (@ARGV<1) { 
    $server_port=9876;
} else {
    $server_port=shift;
}
$server = IO::Socket::INET->new(LocalPort => $server_port,
                                 Type      => SOCK_STREAM,
                                 Reuse     => 1,
                                 Listen    => $maxlisten );

my $top = MainWindow->new();
$top->fileevent($server, 'readable' => \&recedata);
MainLoop();

sub recedata {
        warn "in recedata\n";
        my $data;
        my $n=80;
        my $client=$server->accept();
        if(sysread($client,$data,$n)<0) {
          die "Error in socket read\n";
        }
        print "$data\n";
#       my $data=<$client>;
        my $t2 = $top->Scrolled('Text');
        $t2->pack(-expand => 1, -fill => 'both');   
        tie (*TEXT2, 'Tk::Text',$t2);
        print TEXT2 "$data\n";
}

and it works fine under Mac/OS.
It does not work under Win32 (I tried Windows 2000 and Windows XP).
I used "nc" to send data to the listening socket and by looking at the
connections (by means of "netstat") it appears that the connection is
established.
However the fileevent is not triggered and the subroutine
"recedata" is never invoked.
I am using the latest available Perl for Win32 from ActiveState (5.8.4)
Can you provide any hint?
