How do I modify component positions/locations/vertices in ConceptStation templates? Cannot grab handles or click & drag components.

I am attempting to create several general use templates for our Concepts group. I'd like to be able to modify template components more specifically - it appears the only options I have are to type in the desired dimensions. It does not give me an opportunity to click and drag or to specify which vertex I would like to reposition. 

It also does not seem to provide me with the ability to modify or replace a component - for example, changing curb and gutter from Type F to valley gutter - in the middle of a template without the program deleting everything connected to the element.

I am currently running version 10.00.07.27.

This is a superb product, and I would like to establish it as a reliable tool for our Concepts group. Any information or guidance would be greatly appreciated.
