When I compile the following in perlapp my radio button is blacked out.
Anyone have any idea why?

#!perl

# Headers

use warnings;
use Win32::GUI();
my ($tlver);
my $ver = "1.0.";
my @menu_defn = (
    "File"  => "File",
    ">Exit" => { -name => "Exit", -onClick => sub{-1}, },
    "&Help"                       => "Help",
    "   > &About "                => { -name => "About", -onClick => \&show_about },
);
my $menu = Win32::GUI::Menu->new(@menu_defn);
