If the option 'Visibilty Cuts' is selected when editing a polygon,
the screen may be incorrect, because the computations is not
complete in the editing mode. After calculating the SWR the result is
correct.
If the applet is to slow when editing a polygon, you should switch
off the visibility cuts.
Use Shift and the browsers 'Reload' button to restart the applet.
