Pin Board Application Help - System Tray Icon
When the Pin Board application is loaded, a pin icon is generated in the system tray. When the application is closed (using the ‘x’ in the top right hand corner) the application disappears. However it can be reloaded (back to the point where it was closed previously) by right clicking the icon, and selecting ‘show.’
