Tksurfer requires you to manually redraw the screen for speed reasons. Hit Alt-R when the mouse is inside the graphics window or click the Redraw button on the toolbar (looks like two revolving arrows). Or if your redraw is fast enough, enable auto-redraw but checking the option in the View menu. -- Kevin Teich
