I have just noticed that CVpcb gets locked only by moving the footprint list up and down, there is no need to have the footprint viewer opened.
It's also worth to mention that I'm using libraries included in the package http://library.oshec.org/compressed/all.tar.gz, those are: - con-amp - uln-udn - avr - relay Jaime Alberto Silva Socio / Representante Legal SG Automatización Ltda. Pereira \ Risaralda \ Colombia
