Thanks. SWAMP.  I guess maybe CS6 is laid out a little bit different.  Under View|Show, there is no option for 3D Axis.  There IS an option for "See other options..." and it looks as if alll of the 3D setup is under that option.  In my case, all of the 3D options were still turned on.

I wish it had been that simple, I'm still trying to figure it out.  All was working fine a couple of weeks ago.  I am on the brink of just re-installing PhotoShop.
