I'm trying out your suggested approach and ran into a conceptual problem. I can get the mouse coordinates and convert them to data on the mouseDown event - but then how do I track the mouse movement, since that uses a different event (mouseMove), and the function I'm working with is already tied to the mouseDown? The movement tracking seems necessary to get the "new" coordinates.
