Kiosk mode in Node-webkit not working?

Question

I'm trying out the basic tutorial for Node-webkit. The manifest includes options to make your app go fullscreen or even in kiosk mode, which is exactly what I need.

Sadly, the app does not open in fullscreen or kiosk mode no matter what I put in the manifest file.

I'm on Mac OS, I downloaded "node-webkit.app". I am compressing my manifest.json and index.html into a "app.nw" zipfile, and then opening that with the mac app. Is there anything I'm overlooking?

My manifest file:

   {
      "name": "mydemo",
      "main": "index.html",
      "window": {
        "title": "baby's first node-webkit demo",
        "resizable":"false",
        "show_in_taskbar":"true",
        "fullscreen":"true",
        "kiosk":"true"
      }
    }

Answer 1

OK, so I'm answering my own question here... don't use:

"kiosk":"true"

Instead use

"kiosk":true

I was under the impression JSON always uses quotes around properties...
