2020.5 Just looking around in the new version and was in layout and started zooming around in the 3d screen. Wondered how small it would go. Now it is a dot and no amount of zooming gets it larger, in fact the dot just goes off the screen and in fact moves in several directions. It is almost like it is hitting the edge of a window and then starts bouncing off in another direction. I know I can go to a backup and retrieve a copy, but would like to know why this happened? I do not yet have a 3d layout so I was just trying stuff.
