The Process Browser allows you to view and control the processes in the LispWorks multiprocessing model. See the LispWorks User Guide and Reference Manual for more information about multiprocessing.
Note: The Lisp environment runs several distinct processes in the LispWorks multiprocessing model, one each running the IDE, Listener evaluation, editor commands and so on. The whole of the LispWorks IDE runs in a single process. Each LispWorks process corresponds to a system thread.
To create a Process Browser, choose
Window > Tools > Process Browser
or click 
in the LispWorks toolbar.
Figure 22.1 The Process Browser
The Process Browser consists of a main area in which all the current processes in the environment are listed, and a Filter area which you can use to restrict the information displayed in the main area.
Like other filter areas, you can enter a string or a regular expression in the Filter to limit the display to only those items which match your input, or the complement of this. See Filtering information for more information about using the Filter area.
The toolbar buttons are labelled in Process browser. These buttons provide the same actions as the Process context menu: Break, Stop, Unstop, Terminate, Debug, Inspect and Listen.
Notice that Terminate and Debug are disabled for certain system processes such as the Cocoa Event Loop. This is by design.
