The stoplight over the icons means part needs to be rebuilt right

SF 2009-02-12

I'm working on a small assembly (< 50 parts), and I'mguessing that the red/green stoplight over the icons in the featuremanager means that the parts need to be rebuilt.. So I do a rebuildand they don't go away.. I save the assembly, and they don't goaway.. any ideas?Solidworks Assemblies
