What's the white box above the HUGS, moves when clicked.

I have a white box in the top left corner of my screen, that can be resized lol, I'm not sure if that's what you mean.

In the VC if you look up above you'll see it, its part of the cockpit

Its the light sensor gauge.Its what backlights the panel lettering at night.I find it distracting myself but YMMVchris s
