Using Mac OSX with Hot Corners activated, move the cursor all the way into the corner of the screen you have designated as "hot." Then when running EC3, move the cursor completely into the Hot Corner to get a screen similar to this one. Experiment until you get the combination you want. For example, to view Hot Corners with Two Windows Open, close the Text book and Bb part. To set up Hot Corners: Apple, System Preferences, Desktop and Screen Savers, click on Hot Corners in bottom left corne, select the corner you want to be "hot" and select All Windows or Application Windows.
