Hi ! Is it possible that makecat has a bug ? Because if you make a new catalog it changes the file /usr/lib/interchange/interchange.cfg, but this has no effect because the this interchange.cfg is not used by the Interchangeserver, the Server uses the file /etc/interchange.cfg :( And the makecat Command dont update the file /etc/interchange.cfg . I use v4.8.2 and RedHat 7.1. mfg. Jonas
