if you use Feature.Vector markers to display your markers, try
if(vectorLayer.features.length>0)
vectorLayer.removeFeatures(vectorLayer.features);
to remove the marker before you add a marker at the new position.

or use a DragFeature.Control to drag the marker around.

Or both.
i was not able to update the position of the marker by updating the geometry
and redraw the feature. The label moves to the new position, but the marker
(the externalGraphic) wouldn't move!?

Hi Rosco,
No, I hadn't thought of that. Any suggestions on how to update the position
of the marker, maybe a loop with a new LonLat?

Have you considered a different approach to coding this, create one marker
and move it around.
