Query: great-- *IF* it works for you

The problem with Norton Ghost is that it seems to have problems with some computers and settings, and if it does, it is impossible to get it to work, or to get any meaningful help from the folks at Norton.My wife and I own different Toshiba laptops. For hers, Ghost works perfectly. For mine, installing Ghost causes my computer to blue-screen every time you turn it off, and it never successfully made a backup.As a PC technical support guy, that's what I see in the world. When it works, it's golden. When it doesn't, no power on earth will budge it.Buy it, and if it doesn't immediately work for you, uninstall it and move on to some other product.
