Keep in mind that the directives to Start or Terminate a script are retrieved by the Task Launcher running on the machine. It checks in once per minute with the Dashboard. It could take up to a minute to see the script start or stop.
Starting a script will create a new row on the System and Script Views.
NOTE: To successfully Terminate a script it must be in a Processing status. For example, if it is in a Debugging status, we are not able to interrupt the process and terminate it.
