Viewports, in 3D Perspective, dont view and zoom at same speed as rest of the screen

When a viewport is set up for a 3D perspective view (locked or unlocked) it doesn't zoom at the same speed / ratio as the rest of the paperspace.

Sometimes the object is huge within the viewport and sometimes it shrinks. As the viewport isn't selected it should just behave in a frozen way as you'd expect. It makes it impossible to set up paper space text, leaders etc as you normally would on top of the viewport.

Its not so much about speed - because the viewport stays at the incorrect zoom.

It will print ok once you have it set up, but wont align to any paperspace objects as it should and is really confusing to work around.

Anyone else come across this major problem?

Will test out the locking layer idea.

Yeah locking the viewport layer works, so far so good.

Now here's a guy, answering his own question.

Bravo to you :wink:
