Success (sort of). I put a copy of Mylib in the folder with my project (happens to be on the desktop). Opened the project, opened preferences> library and changed the search path to the project file on the desktop... all the symbols from my lib appeared.
I'd need a different search path for each project. Maybe this suggests that I should move all the libraries to another fixed location.
Thanks for the explanation. Interesting that my version of Kicad has put all the libraries in the Kicad folder (that is in program files (x86) on the C directory)
Maybe I need to delete Mylib from "Kicad>share>library", then recopy it there?
Or move all the libraries to some other location in "my documents"?
You're right, I need to upgrade. I have 1/2 dozen PCB drawings, wouldn't enjoy having to rebuild them if an edit is needed.
Thanks again guys
