Comment (by liuar):

 In ajaxmappane.templ line 3685, [[BR]]

 {{{
 wheelZoomCursor = new Point(msie ? event.clientX - mapPosX : event.screenX
 - mapPosX,
                         msie ? event.clientY : event.screenY);
 }}}
 [[BR]]

 event.clientX returns the horizontal coordinate within the application's
 client area at which the event occurred [[BR]]
 event.screenX returns the horizontal coordinate of the event within the
 screen as a whole.[[BR]]
 So, other browsers besides IE should also use event.clientX - mapPosX and
 event.clientY to indicate the cursor's position on map.
