http://www.virtualbox.org/ Thanks Aigle. I downloaded this today after seeing the mention of it in the long, long, Powershadow thread. I'm fairly new with this sort of thing, but have to say that even I figured it out in minutes, without reading the instructions (I seldom read instructions until I'm totally screwed up). I've used VMware and Microsoft's virtualization programs, but both were heavy on my system. This one isn't. I can't comment much on the other virtualization software except the two I mentioned, but can say that virtual box is open source - free - very full featured, and fairly intuitive enough that even a fool like me can use it with ease. I noticed only a slight hit in resources. I much prefer it to VMware and MS's virtual thing. Again, thank you aigle. This one is staying on my machine.
