Hi,

If I try to localise a form (using the LocalizeToolBar) with an empty mmDataGrid (grid showing zero posts and no column headers) then I get this exception when I close the form-localization form, does anyone know what I am doing to cause this?

Exception message : Value cannot be null.
Parameter name: dataSource
