Hi all.
To circumvent this ( hopefully temporary ) shortcoming, I usually just write the signal handler in this fashion:

#!c:\perl\perl.exe -w
use strict;

my $num = 5;
$| = 1;

$SIG{ 'INT' } = \&stop;

while( $num )
{
  print "I'm waiting...\n";
  sleep 2;
}

sub stop
{
  $SIG{ 'INT' } = \&stop;
  $num--;
  print "$num\n";
}

You have to override the signal handler on win32 machines because after the signal handler is called, it's value ( which is stored in %SIG ), will revert back to the default. Since 'Control-c' is the same as SIG{ 'INT' }, the program will stop executing immediately.

Hope this helps,
