mmm, that's a new one.

It does the same thing in V1 as well, I also noticed that when you mouse over those empty views the coordinate display shows 1.#R 0 1.#R.

Mal, if you Hide all the objects then go to View > Reset all , it resets all the views then unhide your objects and it behaves fine after that.

At first I thought you might have drawn a line say 3km away by accident but all views should of displayed the same thing. Michael will have a better look and explain.
