So here is my dillema...I have two scripts, the first one tails the file looking for any updates: 
use strict;
use warnings;

use File::Tail;

my $name = 'C:\File\test.dat';

my $ref=tie *FH,"File::Tail",(name=>$name,
                     ignore_nonexistant=>1,
                  interval=>0,
                  maxinterval=>0.1,
                  tail=>-1,
                  maxbuf=>16,
                  adjustafter=>1);
while (<FH>) {
    print "$_";
}

and the second sits in a while loop writing data to the same file every second: 
use strict;
use warnings;

open(WRITE, ">>C:\\File\\test.dat");

my $num = 1;
while(1) {
    print "$num\n";
    print WRITE "$num\n";
    sleep 1;
    $num ++;
}
    
close WRITE;

I've messed with the buffer size, tried flushing the buffer via ($|++) on the print side but the script running the tail never seems to update. I'm assuming this has something to do with the file being open on both sides.
Can anyone give me some pointers?
