What is this?

Hey!

Anyone know what this square lookin a bit like a spotlight is? I cant grab it or find anyway to turn it off. I must have typed a command wrong or something…

restarted and it disaperad. wierd.

That is the camera toggled on. (_Camera)

When you run the Camera command in a Viewport, the viewport frustum is displayed in the other viewports.

F6 is the default toggle for the camera in the current view - you may have hit that by accident.
