> Note to Andrea: if you have a chance to confirm the above, that would be highly appreciated.
>From my tests the warning appears only if you open the browser (I use
Firefox) with the "?" button. The message appears when you close the
browser. If Firefox is already open then the message does not appear,
when I use the "?" button.
