it's allowing me to enter negative values in the carrara6pro field
on the upper right of the slider (OS X).
the negative values show their fx on the figure (apollo wizard robe/hat).

d3 is don3? I don't use that stuff at all.  yes, don casual works in c6pro.
trying nose morphs - they allow me to enter a negative value in the field,
which has a result opposite to that of the positive value. 
perhaps there's some difference between
the application of this in windows that disables it.
constraints full/off  has no effect in my case.

some difference in the latest patch, some difference in which version
of poser is being called by carrara as the default runtime, etc.
