5yos have trouble with touchpads, especially capacitive ones that seem easily fooled by ground loops.  I'll have to see about swapping that piece out with one from the rest of my fleet.   Clicking and dragging is too much to ask for without an external mouse.  This is compounded by the fact that if you hold down on the mouse button for too long, a context menu appears (one which does not include "put this in the script pane")

Still, fun to do all the dragging of jigsaw pieces around and chat while the lil'un picks backgrounds and sprites and so forth.
