Maintaining continuity of mouse cursor between slides

That's helpful regarding the timing. I'll change my workflow to instead make use of when the timeline ends vs when the animation ends. I think I just went in the direction of when the animation ends so I didn't have to think about how long the slide's timeline was in any given instance. 

The same file I sent displays the problem with end points and start points not lining up though. As each slide changes the cursor start point jumps all over the place and does not pick up from where it left off on the last slide. The file I sent was the result of creating a few slides and then cutting/pasting/inserting a few slides to move things around.
