For part modeling I normally reorient and rename the planes and update the standard views to match the normal orientation of z-axis to Top Plane (Don't understand SW's thinking on their default orientation)

I'm trying to create an assembly template but  for some reason SW will no longer let me rename the planes.  I do the slow double-click on the plane name, but it won't highlight it so it can be renamed.  Probably a simple solution.... I've done this before without problems. 

I went back to my saved Part template where I made this change and for some reason it won't let me rename the std. planes now either.

What am I missing?....Is some system setting locking them?
