>Two questions:
>1. I’m just a private user of VFP for my own applications. I have VFP7.0 and am considering updating to VFP 9.0. Can anyone tell me if VFP programs will continue to run on later operating systems than Windows XP?

It's confirmed that VFP9 runs fine under Windows 7. Nobody can make any promises for the next Windows version.

>2. When I upgrade, do I need to keep the old VFP 7.0 as well as the 9.0 upgrade, should I need to install on a new computer?

You can keep VFP7 only if you want to do something in VFP7. VFP9 is totally separate product and does not require VFP7 to run.
