I'm using a MDI form where have Menu bar with some button on it that open up the same form. The form just has differnt DbLists on it that they are bound to diferent datacontrols. Every time I close the form and try to open it up with a new button I reset the datacontrol and that when I get the error. I have not changed my location of my driver so what up? Does it have to do with the MDI form.
