Hi Juan.

>I need to confirm how good is the compatibility between VFP8 and Windows Vista for development purpose. Or is it necessary to move to VFP9?

Although VFP 8 works with Vista, there are some visual things that don't look quite right, such as comboboxes that have every item highlighted rather than just the selected one and forms that have missing or corrupted borders. These things also occurs in VFP 9 Service Pack 1 (SP1) but will be fixed in the soon-to-be released SP2. There are also workarounds for these that you can use in VFP 8, but there is no good reason not to move to VFP 9.
