Is this something that the tool is meant to support?
Thanks,

In the next update, the DDT is going to have a checking mechanism to warn you about this type of thing since so many people have a hard time with this. It is a required component as it allows structures to be updated from version 1 to 3 in a single step withou having to load multiple updates sequentially. But this is one of those side effects.
Also, be sure to get the most recent version of 1.6.5 as there were quite a few enhancements made to it the other day (there will be more in the next update as well). http://forum.strataframe.net/FindPost14258.aspx
