It's all part of the retraining issue. I've been mentoring a guy that is moving his commercial 2.x app to VFP. He's using my framework, which uses views and only pulls a few records at a time from the table. It didn't take much of a conversation for him to accept this way of doing things. It's just part of the user retraining for the new app.
