Making an invisible window visible - problems

Question

How do I make a currently invisable window named "newwin" visable from the page that launched the window?
Inside "index.html" I open a new window with the following code:
var options = new air.NativeWindowInitOptions();
options.systemChrome = "none";
options.type = "normal";
options.transparent = true;
var windowBounds = new air.Rectangle(20,25,900,600);
newwin = air.HTMLLoader.createRootWindow(true, options, true, windowBounds);
newwin.load(new air.URLRequest("skin.html"));
Inside "skin.html" (launched inside "newwin" window):
window.nativeWindow.visible = false // works as expected - window becomes invisable
Now inside "index.html" I have a command to make "newwin" visable again (which isn't working):
I have tried:
window.nativeWindow.visible = true (opens up the main application window)
newwin.nativeWindow.visible = true (TypeError: Undefined value)
newwin.visible = true (does nothing - no error but doesn't make newwin visable)
newwin.options.visible = true (TypeError: Undefined value)
newwin.nativeWindow.options.visible = true (TypeError: Undefined value)
newwin.activate()  (TypeError: Value undefined does not allow function calls.)
newwin.nativeWindow.activate() (TypeError: Undefined value)
all come up with "TypeError: Undefined value"
How do I make a currently invisable window named "newwin" visable?

newwin is an HTMLLoader object. To get to the NativeWindow object you can use either newwin.window.nativeWindow or newwin.stage.nativeWindow.
So:
newwin.window.nativeWindow.visible = true;
or:
newwin.window.nativeWindow.activate();
should work.
