Hello,
I just tested
I see that using javascript to close a child page without reloading the parent page.

for example :

close();
or
window.close();
or with HTML
<a href="javascript:close_window();">close</a>
or
<a href="#" onclick="close_window();return false;">close</a>

it still doesn't work.
I think it would be useful if it works
thank you
