Thanks, though it's sort of weird The column heading says that the check mark is to Hide the icon of the application that starts at login. The note below even says "To hide an application when you log in, select the checkbox in the Hide column next to the application." But I checked the box anyway and rebooted, and Creative Cloud came up automatically at login. But then I UNchecked the box and rebooted, and Creative cloud still came up at login. Does that make this the Correct Answer?
