There are three types of job queues: Auto Start, Manual Start and Timed Start. There is a drop list in the Queue tool bar in the Job Queue tab from which you may select the queue type. This setting affects the present queue and is used for any subsequently opened queues until changed by the user.
: In this type of queue, an analysis is immediately started when a project is added to the queue. If a job is presently running, then the project is added to the job list and analyzed when all jobs before it in the queue are complete.
