Working easily off ortho

I tested it twice a few minutes ago and this time it worked fine - only the positive side of the Z axis was shown. My computer stopped working after the first test - I could not type anything and the computer made strange clicks. Maybe it was hardware malfunction.

i am still not clear what is happening. what you say makes sense but when i just swivel around zoom in the viewport without changing a thing using 4View twice still makes a little change in the end. like its forgetting to set it to standard view at the first attempt.

And then I’ve found this but I’m wondering why it’s not easy to call up.
