Good question! One way to go about investigating it is to SAVE
TRANSFORMED the object at the 94% mark. Then you can see if it
is >>still<< planar during the morph. (Of course, it should be,
but what does "should" mean anyway?)
Another thing to try is simply setting the surface to DOUBLE SIDED-
it might help.

This, folks, is a worthy question. Lately some of the newbie questions
have been really painful, questions that two minutess of thought should
have solved. Please, let's keep the s/n ratio up on the list.
