>Esparta, thanks for your reply. What about using the application in 7 again after it has been in 8?

I still don't know, no downgrade yet I'm sure VFP8 is better.
I guess I'd do reverse steps that's why I don't touch VFP8 related stuffs (like auto-incrementals), with controls I just re-code my custom classes (which checks VFPX stuffs, like I did with VFP6->VFP7)
