Mass Properties Calculations

I am checking the mass properties on an assembly with over200 components. I get a message that "One of the componentsrequires updating. This may cause the mass properties calculationto be out of date" Is there any way of determining which componentmay be the problem? Otherwise, it is a fairly useless message. Kindof like saying "your results may be right, or may be wrong, butyou'll never really know". If anyone knows of a way to track downthe offending component, I would appreciate the help.Thanks.SolidworksAssemblies
