File»New Job (Ctrl+N)

You can select New Job from the File menu. This will bring up the CERUN launch panel so you can set new options for CERUN to use. This includes running CERUN against a different MCD file or CE. If you want to restart CERUN using the same settings you currently have, use the Restart command instead.

Stops control emulation and returns to the launch panel where new options or an entirely different MCD file can be specified.
