**The thing is, with the way they have redone V4, is that if you have more than one !DAZ folder anywhere on your computer, it can mess things up. At least that's what they keep saying.  Poser will refer to the very first !DAZ folder for the morphs it comes across and if that one does not have the update for V4.2 and A4, then it can mess the model up in strange ways. That's why I suggested zipping up the original and storing it. Then if you decide you do not like V4.2 or A4, you can always unzip her back and run the updater again and restore V4.1 that way.

It's not the extra runtime itself that causes the problem. It's having more than one version of the !DAZ folder with different updates in them. And apparently, the order in which you apply the morphs. I've seen it stated by Daz tech many times that you must inject the base morphs, then the ++ morphs, then the character. Why, I don't have a clue. Just going by what I've read.

The only other thing I can think of that could possibly give her strange expressions is the pose itself. It's possible if it was a pre-made pose (one you didn't do yourself), then the creator of the pose left something that shouldn't have been there and that changed her expression. Or it could be part of the pose itself and that changed her. (Used to be people included facial expressions with body poses for whatever reasons.) Another thing I have seen people say is that in Poser, you want to turn the IK off on V4.2 or she does really weird stuff.

Oh yeah...was the body pose for V4 or A3? I ask because you you do need to use V4 poses on A4. A3 poses mess her up as much as V3 poses would. Just trying to think of possibilities here.
