I have been running 3.47 on my desktop for some time and am very happy with it. I recently had some problems with my XP system and have set up a new XP partition. I notice that Daemon-Tools has moved on to a newer version 4.?? but have been troubled with the "system needs to reboot before continuing" scenario. A search of this forum has found a suggestion to edit the registry which I will do when I can get my wife off the desktop. Meanwhile, can someone tell me what are the benefits of the current version over 3.47?
