Moving a drawing point is not possible. You need to clear the drawing and paint again.
Here's a tracking example: http://www.mapwindow.org/documentation/mapwingis4.9/_tracking_8cs-example.html
If you have other data that needs to be drawn you can add them on separate drawing layers or create an in-memory shapefile.
I hope it helps,
Paul
