Robert, I appreciate the response, but I'm using version 2.0 of the viewer. I used the thread I linked above to implement the NavMenu successfully. However, what I want to use is the newer Navigation tool that's being used in 2.2 and up. I've been able to get it loaded by adding it to index.mxml, and everything is working. The exception being the icons and labels for the pan and zoom in/out tools. It should be so simple, but I can't figure it out.
