Does anyone know WITH ABSOLUTE CERTAINTY if this behaviour still exists in 7?

I do not use RV's with remote data I use SPT.

Even using Local Views .. SDT becomes a must have tool. I was forced to maintain a medium scale application that relied on Local Views. It was very difficult to alter table structures. I had to re-do every Local View.

Stonefield is extremely well made. However, like any data dictionary, it slows down processing to a certain extent.

Extremely fast database operations (with native data) is the purpose of using VFP.By relying on ANY data dictionary you are crippling VFP's #1 selling feature.

I am leaning towards building my own "View Maintenance" system so that I am not "required" to use Stonefield.
