I have a workstation with two monitors attached.  Both work.  However, in Settings where you set up monitors, it shows the two monitors (1 & 2) and then it shows monitor number 3 kind of grayed out.  Why is a 3rd monitor showing?  The real problem is:  When we open an app that's been minimized, it flys off the screen to the side, thinking it may think there's a 3rd monitor its trying to find.  Any ideas appreciated.
