I use Mint 17.3, and really like it. Occasionally I'll see in the tool bar [I think that's what they call it], the bar at the very bottom of the screen with the icons. Anyway next to the icon showing if updates are available I see what looks like a red ballpoint pen. It's not there all the time, only on occasions, like once or twice a year. Left or right clicking on it does nothing. Does anyone know what it represents? Thanks!
