I am running an Access2000 adp, and have a form with a combo box to select a key field; after update the unbound parent control is populated, the subform requeried successfully, but the value that appears in the parent text box is garbage, and access becomes corrupted. I have checked out my source data, and altho a possible cause of the error, the data has been loaded by a stored procedure and Enterprise Manager does not show any data error of any sort - what could be causing the corruption
