Though InDesign Help claims their is an "unlink" option in the drop down menu of the links panel, it seems at least that my version of InDesign 6.0.4 does not have that feature. I am aware of the option in preferences to not allow text files to be linked, but this is a furnished file that has missing links for text files, which we do not want to update.
Does anyone know how to activate this rumored unlink option in version 6?
