Ah yes, I almost forgot about that one, thanks for reminding me! But as
you say, with 'S' the resulting polygon is, erm, rather 'promiscuous'.
Still, I think it's the best option for most of my bigger pads -- and I
see that the best way to go about is to first create the polygon on a
spare layer (so that its boundaries are clearly visible), then toggle
the PolyClear flag, and then Move it to the intended layer.

Well, it used to work without tripping DRC errors -- but now I think
I'll have to clean up my act :-)
Thanks again, regards,
