So in a query you already have FieldsVisible...
FieldName=F
but you can still see the column on another form that uses this query.

Do you understand the the FieldsVisible options only impact whether
the field is visible in a grid? It will not change the visible state
of a control setup to use that field.

Also, you can still include such columns in a grid by explicitly
defining them to the GridLinks property of the grid.

Does any of this explain what you are seeing?
