Hi I have upgraded to 13.3 from 13.1 systems modeler and I can no longer edit my library. If I right click on a package which contains existing models and try to add a new class it is greyed out and I can't select it.With the same library it works fine in 13.1 version.
What has happened between the 13.1 and 13.3 release to cause this. Is there a solution.
Thanks
