I am having a reocuring problem with a grid in a form. Once in a while after editing the form the ControlSource of all the columns in the grid will get set to (none). The grid ControlSource will still be set corectly. The form and grid work correctly until this happens. There is nothing special other than one column is a checkbox. The grid is based on a view and the view is in the data enviroment. So far I have not been able to connect this problem with any specific change made to the form.
Anyone have any suggestions?

Thanks, Dennis
