  prefDir           1x1               170  string                      
  status            1x1                 8  double                      

In particular, having an empty double named 'i' is not good as that can screw up code by shadowing the built-in function i that returns sqrt(-1).

Ooooh ... interesting

i*i

Ouch! Report them as a bug. In particular that i.

I reported the i situation several months ago.
