Window widget problems

I am having problems with the netWindows widget after 'removing' it from 
the screen.  Once the widget has been removed from the screen, events 
that are associated with the elements within the window still fire.  
This is causing some major headaches and needs to be solved.

Here's how we create the window:
     
  _nwLineItems = NW_WIDGET_FACTORY_window("Invoice Line Items", 100, 
100, 390, 300);
        document.body.appendChild(_nwLineItems.domNode);
        __env__.addToPageQueue( "<our page>",
                                _nwLineItems.contentObj.contentNode, false,
                              _invoiceItem = new InvoiceItem(_drs, 
_nwLineItems, insertItemClosed, this), "constructor");


and to 'close' the dialog from within the _invoiceItem, we:
            _dialog.remove();

( where _dialog is a reference to the window widget )


Is there some other call we are to make to properly remove the window 
and the events?

Thanks for your help!
