I have inserted named views into my drawing from the sheet set manager. When I try to edit the view through refedit, some of the layers are frozen. It looks like layer 0 is always frozen. I tried updating the layers from the named view dialog box of the referenced file, and then inserting the named view again. I'm confused as to which layers will display frozen and why. Can some one please explain? I have visretain set to 1 so changes carry through.
