When I run the code below I expect to see one print statement every time a file is saved but instead I always see two or more print statements for each save. Does anyone know why this might happen and what I can do to get around it? i only need the last notification. 

use Win32::AdvNotify;

my $obj = new Win32::AdvNotify || die "$!\n";
my $thread1 = $obj->StartThread(
                     Directory => "C:/spot/run",
                     Filter => LAST_WRITE,
                     WatchSubtree => Yes ) || die "$!\n";

$thread1->EnableWatch() || die "$!\n"; 
while($obj->Wait(INFINITE)){
    while($obj->Read(\@data)){
        for($i=0;$i<=$#data;$i++){
            print "$data[$i]->{FileName}\n";
        }
    }
}
$thread1->Terminate();

$obj->Free;
