iSina: What might be the reason for this behaviour

from your code posted as Anonymous (Re^2: Autoflush/Buffer Problem), I can see that you
use Tie::File on an already opened file: 
 ...
 my $input = $mw->getOpenFile();
 open FILE, ">$input" or die $!;
 FILE->autoflush(1);
 ...
 tie @lines, 'Tie::File', $input or die $!;
 ...

This is, according to the Tie::File documetation,
not supported. You have to provide the filehandle: 
 ...
 open FILE, ">$input" or die $!;
 tie @array, 'Tie::File', \*FILE, ...;
 ...

From your code fragment posted it can be seen
that there are at least one zillion interactions
with other (unposted) code parts that may contain bugs ;-)

So one can only wish that the "force may be you" in
cleaning up this program eventually ...
