+## Limitations
+Keep in mind that there are some apps which "One Click Quits" cannot terminate. Such as apps have background processes, or apps that continue running in the background once its window is closed.
+
+This is a limitation due to how the logic to close applications was programmed. It does not listen to close events, rather it checks periodically if the application's window ID is still valid. To keep the program from closing apps that do not have windows, it checks if the app in question has a "modeOnlyBackground" flag. If it does, it will not close the app.
