To prevent IBM® Rational® Rhapsody® from saving graphic editor settings, set the General::Workspace::OpenDiagramWithLastPlacement property to Cleared. With this setting, the product does not save the position of graphic editor windows. Instead, it uses the default window settings the next time you open a graphic editor.
You can prevent the product from saving any window preferences by setting the General::Workspace::OpenWindowsWhenLoadingProject property to Cleared.
