Trapping mice and moving points

I'm trying to make a bathymetric map of a lake. I've collected GPS points around the lake shoreline. Fallen trees in the water prevented me from reaching the shore in several areas. I can see these differences in an overlay of the points on a satellite image of the lake.

I'd like to use JMP to add new points and to move old ones. I've cannibalized script examples and cobbled something together that almost works. There are two problems: the new points, though they appear in a new dataset, do not appear on the graphic, and the dragged points appear on the graphic, but are not added to the new data set.

The jsl file with my data is attached. Suggestions welcome.
