OK Update guys!!!

I fixed it!!!

One of the things I did was Turn On the USE External Binary morph targets in the preferences. People had told me not to do it but i gotta test it and it seems it makes everything better. 

For example what i did now is load my CharacterGroup from the libraries on to the scene. I tested moving a characters arm, and i couldn't at all. The other character was fine. So what i did is delete the character that i can't move .. and reload a new copy of v3 and put her in her place..clothed her, and apply any morphs so she looks exactly like the v3 that was there.

Then test her, and i can move her freely  now cause she's a fresh v3 copy. Then i set her parent to the cube.  Then i saved the file into the libraries again. 

You know how long it took to save now that i have USE EXTERNAL BINARY MORPH TARGETS on? It took less than 20 seconds. versus 3 minutes it would take when i had UEBMTargets OFF.

Well, so then i proceeded with an empty scene and i wanted to test if the Character group i saved in the libraries works?  I loaded the new character group: one jamese clothed, one v3 clothed.. Using the translation tool i tried to move the arm of the v3 in the group and NOW IT MOVES!!!!!

So
there are two possible reasons as to why i couldn't move the characters:

1. Poser just got confused and wrote bad data as it saved the characters to the library
   2)this happened because i had UEBMtargets OFF.
