I too have seen the moving components (not for a long time though), for me at least, they have always existed in the netlist and the component report. I had not noticed what happens to the ratsnest when a component is off in ga-ga land but it still exists in the database, the netlist, the component report, the ASCII PCB version and even component browser. I have not checked if they exist in an exported spreadsheet. Thanks for the info on the ratsnets not showing for the "gone-ape" components (technical term), Ian Wilson * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
