We are aware that the task "Quit All Applications" is not working with recent system software and we are about to remove it in future versions of the app.


The good news is that the script  is not part of the core features of the app, it's a script file provided with the app as an example of what user can place in the Tasks menu, you can delete it or you can replace it with another script or edit it. Please use the Tasks files to edit the Tasks menu items.
