If you have a job running, you can start another job by switching to the ARC Connect “Sessions” tab (A), selecting the “Create new session” radio button (B) and then clicking the “Switch session” button (C):
After you have done this, you can switch to the Job tab (D) to start a new job. You can switch back to an already running job using the same procedure.
The green check mark (E) indicates which session is currently available under the Job tab.
If no job is running in the current session, the “Create new session” radio button will not show up and instead a radio button that says “This session” will be present. In this case, either switch to one of the other available sessions or click on the “Job” tab to start a new job in the current session.
