[TIMOB-1278] leftNavButton not showing up in simulator on iPhone OS 4 and sdk 1.3.2

Hey all, I can't get the leftNavButton to show up in modal windows after upgrading to to iPhone OS 4 and sdk 1.3.2. They worked in iPhone OS 3.2.1 and sdk 1.3.0. Possible bug?

// create the close button and listener for the main window
var button = Titanium.UI.createButton({
    title:'Close'
});
// create first window and the navigation group
var first = Titanium.UI.createWindow({
    title: "Courses",
    barColor: '#005a84',
    leftNavButton: button
});
button.addEventListener('click', function(e) {
    main.close();
});
