I've got a serious autorouting bug - if "Comp layer" is unchecked,
routes passer right across a pin on comp. layer! (purple arrows).
Blue arrows - I see a "PostScript small marks" inside tracks on the
components layer.
DRC shows errors on each such place, but autorouter thinks all ok =)

P.S. to Dick Hollenbeck: Export to .dsn format seems not using this
property. In freefouting.net I dont see a difference between "comp.
layer" checked or not on separate pins.
