When editing ZSpheres under 3.1 a shift-click got you an added ZSphere
of the same size.
Under 3.5R2 I either seem to get nothing at all, or I get a ZSphere added
at some random location in the model !?
Is this intended? Is there some setup switch to get me the old method?

Edit: Spotted something else. As I rotate the ZS model, it sometimes
vanishes from the screen entirely!
