I have 3D fine, I can do all of the 3D stuff on a 3D model with textures, but to manipulate the object in 3D space I have to use "coordianates -- ther are no tool to rotate, scale, or move the object.  There used to be, and it was working fine, but suddenly stopped working, as if I had inadvertanly turned something off!  But I sure can't figure out what, if anything, I did to mess this up!
