Thanks Markozeta for your replies, and quick too. I would have responded sooner, but had a time of it logging on. But the info helped and I am on my way.

Thanks, Brian

Thanks for getting to me so quickly, here is the file.
I have made and remade it several times and always get the same result.

I have a simple Dynamic Component built of only three sub-components. I am trying to resize it with a drop-down list of differing widths with two of the three dimensions constrained. When I select a different width setting the sub-components shift relative position and their over-all size is bigger than it should be. Any thoughts?
