IP Parameter Editor not selectable

We reorganized because we did not like how, by default, everything had to exist at the same directory level or as a subdirectory as the quartus project file. The tools generate a ton of trash meta-data/intermediate files that quickly clutter the directory structure. We just wanted : Altera Project in one directory, all source code in a different directory, constraint files in a third directory, and testbenches in a fourth directory. This makes it much more intuitive to find what you are looking for, especially to someone unfamiliar with the project.
