Help find a way to make zone which is not connected to any net. I found this discussion: http://www.mail-archive.com/[email protected]/msg05485.html . Here say:
"Click on the zone tool A window pops up, select the net that you want the zone to attach to, or no net for isolated zones" How to select "no net" when PCBNew automatically selects first net in list by default? I use PCBNew version "20080825c-final" from Ubuntu's 9.04 reposistory.
