That is the problem, the form works if filter is removed in the data enviroment (in the sense that it is displayed, obviousely the results are incorrect).

The point is that I feel strongly that I should not have to rewrite almost all of the forms in the application. I think this is a bug. It works up to VFP 8, why the sudden change in behavoir?
