Hi, (I've posted this once, but it seems my work news server is playing up - hopefully this one will work and apologies if it appears again) Reading around the documentation of our new IC 6.1 install, I've found the section on creating combined libraries in libManager.pdf. This makes me very very happy, but I've not been able to get them to work. I've tried with different libraries and ASSIGNs and even with the following line I see nothing extra in the library manager: ASSIGN newLib COMBINE analogLib basic I'm not using lib.defs files (I've even set DD_USE_LIBDEFS to NO to be on the safe side). There are no warnings or errors in the library manager log. Enabling/disabling different library display styles doesn't seem to make any difference. Has anyone had combined libraries working in Virtuoso 6.1.3.1? Am I doing something stupid? Thanks, Roger
