Does anyone know how to name a solid body and have it retain the name? I have an overmolded part that became two bodies (created a shell, extruded an unmerged boss up to the shell and shelled that out), and at that point I tried naming the two parts. Didn't stick, but if I roll back to that place in the tree, the names come back. I read elsewhere in the threads that this should have been corrected in SW2009 - so am I doing something wrong?

Also, and I think related, if I roll back in the model and change a feature significantly (but doesn't change the two separate bodies, they remain separate) all features below that point in the tree no longer know what body they were supposed to have in their scope. How can I prevent this?
