The DDE indicator is found in the status bar of the main window. It indicates if the currently
active network window has any DDE connections to other running applications. If
there are DDE connections, the indicator is on. Otherwise, the
indicator is greyed. In figure 1 the DDE indicator is on and thus it
indicates a DDE connection.
Figure 1: The red circle shows the DDE indicator in the status
bar of the main window. Here, it indicates that there is at
least one DDE connection to another application.
