Win32::Setupsup quandry

[Grygonos]

Fellow Monks,

I have the following test script

#!/perl -w 

use strict;
use Win32::Setupsup;

my @windows;

Win32::Setupsup::EnumWindows(\@windows);

foreach(@windows)
{
    my @proptoget = qw(focused pid);
    my %windowprop;
    
    Win32::Setupsup::GetWindowProperties($_,@proptoget,\%windowprop);
    
    foreach my $key (keys(%windowprop))
    {
        print $key."-".$windowprop{$key}."\n";
    }
}

that should grab all the windows and grab the values of the focused and pid property. However when I run the script I get the following usage error: Usage: Win32::Setupsup::GetWindowProperties($window, @proptoget, \%windowprop) I do have a valid window reference because printing $_ gives me the handle. focused and pid are valid properties. I am passing the empty hash by reference. What am I missing?

Thanks a TON in advance...
