In CCS 11 there is a way to "Hide" a panel and not be able to get it back within the interace. The only way I have found to get the panel back is to delete the console preferences in the application data folder and then relaunch the console. Please refer to the attached document for more information. I have found that a couple of panels have been hidden in the SE Demo image on the Monitor>Evaluation Results page. So if you see a blank space where you are expecting a panel, please look at the document for further information.
