Combining co-incident vectors

When I import DCW country boundaries, I get co-incident boundaries.
So say I import France, Belgium, the French & Belgian border have two vectors, one on top of the other where they meet. Is there a way of deleting all but one of the common elements in the boundaries between the countries?
The reason is so that I can apply line type & colour changes in one go.
I have tried using the edit tool and can do most of it manually, but as some of the common elements have discontinuities in different places, I land up losing bits of boundary.
Thanks

There is not a way to delete all but the common bits of boundary, but I wonder if you could perhaps use the Search->Search by Attributes menu command to identify the pieces of interest you another way and change their style like that. The DCW data should have lots of attribution that you could use to find just what you are after with a search (or perhaps several nested searches).
Let me know if I can be of further assistance.
Thanks,
