1. Sometimes the crosshairs leave artifacts. If I use the crosshairs and move it around the screen, sometimes a vertical and/or horozontal line gets left behind. I find that if I move the crosshairs back over the exact same spot, I can "pick up" the artifacts and clean it up. Or, do something else to redraw.
2. what is the difference between the cross hairs and the global cross hairs? Global sounds like, well, global, like maybe on all charts. But, I don't see any difference.
