Needing the CD-ROM to run the program every time, doesn't seem safe. The more a CD-ROM is handled, the more risk there is of it getting broken or scratched. I want to load Poser 5 or whatever, no waiting while an email gets from Manchester (UK) across the Atlantic and to the far side of the USA, and is handled there, and the answer coes back. After that I want to put the valuable load CD-ROM back away in its case in a drawer safe and leave it there safe and not touch it again until I must reload again, and NOT have to carry it about with me if I have a laptop and I want to run Poser away from home.
