I have a *hopefully* reletively simple question. Here is what I think may be happening.

1. I find the part (ie 4-40 screw) in the vault and drag and drop it into my assembly. (I do not have ownership of said screw)
2. It updates from older version (2009 or 2010)
3. I mate it in place.
4. Save new assembly, and check it in the vault (still without ownership of screw)
5. Next time I pull the assembly out, my mates fail.

  Is this happening because I did not gain ownership after the version update for the screw?
