using Win32::IEAutomation; how to maximize IE

[itshardtogetone]

Hi,
I have the script below but IE did not maximize. What must I do to maximize IE.
Thanks

#!/usr/bin/perl
use strict;
use warnings;
use Win32::IEAutomation;
# Creating new instance of Internet Explorer
my $ie = Win32::IEAutomation->new( visible => 1, maximize => 1);

# Site navigation
$ie->gotoURL('http://yahoo.com/');
