There's a morph-zeroing script reference in this forum, but I don't recall whether anybody did
a morph-deletion script.  such an item would be valuable for OS X users (no Morph Manager
for OS X, although MartinC did write one for OS 9).

p.s. as you may know, few or no python scripts will work in any version of poser (OS X)
prior to 7.0, in case anybody wishes to test python scripts in poser 6 (OS X).
