Oh dear. I’m writing an article on DRM and was trying out Napster. The way this works begins with installation of the Napster application. I ran setup on my Vista Business machine, and got a blue screen. Undeterred, I restarted and ran setup again. This appeared to work, although the PC demanded a restart and took ages to shut down. Unfortunately, when it did eventually restart, something was not right. I could log on, and the desktop appeared, but I could do nothing more than move the mouse pointer; even Ctrl-Alt-Delete could not pull up its menu. Solution: restart in safe mode, remove Napster, restart. All fine now.
I’m sure I was just unlucky; but it’s a nice illustration of why Apple owns this market – though iTunes can be problematic too.
