But... isn't that what close is supposed to do?
I need an endless loop!

But I have (good?) news. I stopped using arcs and the problems just went
away. I'm using lines with fillets. I still have a problem, though.

This file:

line -55 105 .6 -55 95 .6
fillet 3
line -55 95 .6 -45 95 .6
fillet 3
line -45 95 .6 -45 105 .6
fillet 3
line -45 105 .6 -55 105 .6
fillet 3
close

...can't seem to make a fillet between the last and the fist lines
(connected with close).

It may be. But as I told you, the problems went away when I quit using
arcs.

thanks for your help
