I would start by saying that this is a problem which is troubling me a lot and hence I do need a solution to this one sooner rather than later. The thing is that this had happened to both Norton 360 v4 and to v5 after upgrading. After my computer starts up and after Norton icon shows up in tray by clock the problem occurs. Then I see at the bottom the Windows Mail pops up and then closes right away near the start to bottom left. My work has been badly stuck up because of this and this is really causing me a problem. Please do reply to this immediately.
