In the property sheet. I create my cursor with the data in the form's Load.

I'm using VFP8, but I do remember I was having the same problem with VFP9. I just was unable to find that thread of mine.

Also see my other message today on a similar problem (Re: A nasty limitation on the VFP native grid or is it me? Thread #1158526 Message #1242866).
