ConceptDraw Community

I'm trying out ConceptDraw, and want to use it for doing some database ERD diagramming. So I opened the ERD shape library, and drag a table shape into the document. The shape comes in tall and skinny, and I'm not able to resize it! The handles only allow moving the shape, not resizing it, and if I open the Geometry inspector and click on the geometry icon, the width and height are grayed out and can't be changed. I've tried grouping the shape and other weird things, but to no avail. This isn't very useful of course, so I'm hoping someone here can explain how to work with these shapes?

Thanks very much.
