Software Simulation: Edit Mouse Points

Hope you are indeed talking about a software sim, not a video demo because that image is so small and blurry I cannot figure it out.

For a software simulation you will be able to move the start point of the mouse path on the first slide of a sequence. Not on the other slides, because the end point of the first slide needs to be in the same location as the start point on the second slide, to have a continuous movement when playing the demo. BTW I largely prefer a Video demo over a software sim in demonstration mode because of its better quality and more editing features.
