        }

    ]]> 
</fx:Script> 
<s:Button id="btnClose" x="44" y="47" label="Close Browser" click="btnClose_clickHandler(event)"/>

Answer 1

Ive found that browsers are inconsistent in interpreting the second parameter of navigateToURL.

If your swf is not in an html frame, you can use "_top" instead of "_self" (which does work across browsers):

navigateToURL(url,"_top");

Or just leave out the second parameter completely (as the default is the same as targetting "_self"):

navigateToURL(url);

Answer 2

What you are asking for is not allowed in most browsers, and for good reasons. You would have to exploit bugs or hacks to achieve it...

A popular one was to refresh and close it in javascript:

window.open('', '_self', ''); window.close();

My advice would be, dont do it.
