Window Menu

The Window menu lists the currently open Object List Editor, Application Designer, visualization view, and other windows, and allows you to navigate to windows that Siebel Tools does not currently show. If one of these windows is open, then Siebel Tools displays the Close menu item as the first item. The Close menu item closes the window that is currently active.
