Glad you have that bit figured out :)

 

They seem to be. But, what are they FOR???

 

External Binary Morphs were intended to be used as a mechanism for people to distribue morph targets independent of the main Poser file.  Instead, they've cause nothing but heartache, particularly for new users.  My advise, never use them.  You were exactly right to turn off external morph targets in Poser.
