Scott,

I can remember (vaguely) of having problems with open-ended polygons  
in Run Rev v. 2, In the old Turtle Graphic days.

  As I recall, Run Rev had a pension for closing the polygon--as you  
can image any geometrician would want.

I found I had less problems, particularly with RR closing the polygon  
for me, when I changed the style (why  does the tool tip read "type"  
in the inspector?) to "line."  Of course you can close the "line"  
graphic by

set the points of grc "myLineGrahic" to the points of grc  
"myLineGraphics" &   cr & line 1 of the points of grc "myLineGraphics""

The "line" style allows multiple points and doesn't seem to fuss with  
closure.
