Stoping the configuration of the engine Sept 16, 2015 17:00:04 GMT Lanz likes this Quote Select PostDeselect PostLink to PostBack to Top Post by Suzy on Sept 16, 2015 17:00:04 GMT If your output goes full screen on your zookeeper screen, then you can stop the engine. This could also present its self as a black zookeeper screen. Hold down CTRL and ESC for 5 Seconds, and the engine will stop allowing you to reconfigure the output manager. Make sure your zookeeper screen is not a selected viewport.When you do this, windows will flash between the start Bar and the engine screen. This is normal.
