Oh yes I agree, it is a really odd behavior! It seems they have do something to correct that in 5 but it is not as it must be, you have a button to close the dialog... It saves changes, and don't launch the render, but it is a little bit hidden (2 per 2 pixel button in the top right of the dialog). Since Vue 4 Pro there is the camera manager too, it is another way to do that without rendering;) But you never think to that and while moving your cursor to the ok buton, you know you are doing something wrong, and then...you click! "Oh f... this stupid button again (growl)" :) Like when you want to test the thickness of ice on a lake with your foot, knowing pertinentely that it is not more than some millimeters...
