I'm running V6I under Vista Ultimate 64-bit. I can set the folders for added objects, plants, materials, etc. However, when I go back into the Vue the next time, about half of them are no longer recognized. I get the error that Vue can't find them and do I want to browse to where they are. Once I do that, all is fine... until I open Vue the next time. More info. I had them all on my D: drive and just moved them to another drive - an external drive. Yes, the drive is on, when I'm running Vue. So, I know there's a way to get Vue to recognize material on a drive other than C:. I did it before to get stuff on the D: drive in the first place. Nelia
