I have a multibody part, shown rolled back here to 2 of the 3 bodies. Strange things started happening while editing this file. A material was applied to one of the bodies, but it cannot be removed now. Also, the feature history shows for that body, but cannot be hidden. See picture below. When I right click on either body to assign a material the option does not show in the popup menu.
Solidworks 2013 SP 4.0
Tried doing a repair, resetting the registry, and even an uninstall/reinstall with no luck.
Any suggestions would be welcome.
