MyApp opens with a DO FORM MyForm1 followed by READ EVENTS. MyForm has no dataenvironment. It is there in case the user wishes to copy a file from A: to C: before beginning. When user clicks "Don't Copy", the click event is simply THISFORM.RELEASE followed by DO FORM MyForm2, which has a dataenvironment of two free tables. But just before MyForm2 opens I get a "Table has no index order set" error message. A combo box on MyForm2 was built with data from one of the free tables. I can't find whatever is calling the table. Why else whould an index be needed?
