If you're using a MacOS Computer, you may see this icon in your menu bar:

This is for the new Samsung Interactive Displays around campus. If this is something you don't currently need and would like to remove the icon from your menu bar, follow these steps: 

1. Open System Settings
2. Click General
3. Click Login Items
4. Scroll down and find the entry called "Touch-Base Ltd". Toggle this off.
5. If you opened any tools from the menu (i.e. the annotate toolbar) and can't see a way to close them, you will either need to log off or restart to make them go away.
