This is probably a newbie question and I am one, when working on my project on the stage, the slide (all of the objects together) moves too easily. The stage window has sliders to permit view a lot of real estate that is outside the slide and objects, and, I'm not using that space for anything.
Even a slight swipe on my Mac's mouse or touchpad send the slide careening out of sight. Very annoying.
How can I lock down the slide on the stage or get rid of the extra space around the slide?
