This happens both on a local machine and also on a server.

I am well aware of handling the problem of creating the control source / recordsource each time I create the underlying cursor. I have used grids based on my base grid class, which handles that problem explicitly, for about seven years. I have hundreds of grids build this way.

As a matter of fact, I have many instances where I allow the user to make changes which give new selections of columns.
