By default, tools windows are re-used where possible. For example, suppose you already have a Listener window (potentially iconified) but do not have an Inspector window. When you choose Tools > Listener in the podium, the existing Listener is displayed. When you choose Tools > Inspector , an Inspector is created and displayed.
You can switch off re-use of tool windows via the command Works > Tools > Global Preferences... . Uncheck the Reuse all tools box and click OK . Now, when you choose Tools > Listener a new Listener is created, regardless of whether one already exists, and other tools behave in the same way.
The setting of Reuse all tools will be retained for your subsequent LispWorks sessions.
