>Stonefield was causing my problem because I had overlooked the SDT property "View field property inheritance". So I discovered yesterday that a lot of my views were making double calls to the NewID function.

Just out of curiousity Bill, are you saying the problem was resolved by turning off that SDT feature in the view? And is that something that's on by default? IOW - do we have an official gotcha here that we have to sidestep with using MMF & SDT?
