Problem exiting application

Question

I have an aplication that I have been working on in flash CS4, it is an air application. When I close the application using the main windows close button it appears to close but is still running when I look at processes.
If I close it by calling exit from the main menu it closes properly. I guess I am probably missing something obvious but I am not sure what.
I set up a listener for the application
NativeApplication.nativeApplication.addEventListener(Event.EXITING,onExiting);
and I setup a loop in the onExiting function to dispatch a closing event to application windows check to see if it's prevented and if not close the window.
However on testing the onExiting function is not being called when I close the application from the main window clsoe button, only form when I use the menu.
To try and see what is causing the problem I did a trace on the loop for open application windows. there are 2 one is the main program and the other is untitled both are normal windows. Since only use one window in my application I don't understand why there are 2. But I guess it's the unclosed window that is keeping the program from closing.
any help will be appreaciated.

Ok this is really really frustrating. This blo*dy forum system is cr*p I have lost my message three times and if this gets through its a miracle.
anyway my message
It is beginning to look like a but in AIR or flash CS4, I have stripped the program I was working on down to a window, an event listener and a function to handle the event.
here is the contents of the wizard.as file
package {
    import flash.display.*;
    import flash.events.*;       
    import flash.display.NativeWindow;
    import flash.desktop.NativeApplication;
    public class wizard extends Sprite {       
        public function wizard():void
            NativeApplication.nativeApplication.autoExit = true;           
            NativeApplication.nativeApplication.addEventListener(Event.EXITING, onExiting);
            trace("setting listener");
        function onExiting(e:Event):void
            trace("exit called for ");                       
I will try to attach the files but it has not work 3 times so far.
When I close the wizard via the close button I get intermittent operation of the event, it works about 1 in 10 times I run the program. I have not been able to tell when it will or will not work.
here is the output
when it works
[SWF] wizard.swf - 2040 bytes after decompression
setting listener
exit called for
Test Movie terminated.
when it doesn't
[SWF] wizard.swf - 2040 bytes after decompression
setting listener
Test Movie terminated.
