I don't know, but I've heard Win ME is not a good thing and that Win 2K is far better, so that might be the problem with the errors. I'm still using Win 98 SE, and I don't have these problems. You have to figure though that I think Dan wrote VM under Win 95--- maybe 98, I can't remember. but if you can get Vue 4, I would highly recommend it. You certainly have plenty of RAM and other resources for what you want to do. :)
