Default value: t

If t , then after the application has opened at least one CAPI window, whenever the application is waiting for input, a routine is run to check whether any of its CAPI windows are still open. If there are no open windows, the application exits.

Note: a multiprocessing LispWorks executable will stop multiprocessing when there is no process other than the Idle Process. So if your application simply displays a window, which is closed, then multiprocessing will stop. This is independent of quit-when-no-windows .
