Pessoal, onde é configurado isso:
The Design-time Settings section of the outline contains a "Reject Multiple Window Instances?" item. When you set this item to "Yes", SQLWindows generates a runtime error whenever the user attempts to create a second instance of a template (form window, table window, or dialog box) or MDI frame. By preventing the creation of more than one instance of a template, you eliminate the need for window handle qualification; a template qualified reference will always be a fully qualified reference. The default for this item is "Yes" for new applications, and "No" for existing applications which are converted to release 4.0 by the conversion program. Agradeço a atenção de todos. Helder
