Lou, I think he took screen shut during the  Pressure gauges indicator was going to "0". If he waited couple of second, pressure will show zero. Ahmet :D

It's possible that I took the screenshot too soon after turning the switches off, but I can't remember.
I use the Snipping Tool to get only the area of the screen that I want, and as soon as I start it, the screen freezes at that point.
