It sounds like maybe the default scale settings on import are not right in some way. Granted, I haven't altered mine since installing it and haven't had any problems like this, but but it's a possibility that it could have picked up scale settings from a previous install... maybe. I just finished doing a full figure sculpt on M4 for a new package and didn't run into any problems at all, so that's where I would look.

Here's an interesting test, btw: import the v4 mesh into your zTool, then without doing anything, export it. Now in Poser, import the original v4 mesh and try applying that mesh you exported from zbrush as a morph target and see if there's any movement. If there is, then something is moving your mesh on import, possibly throwing the center point by some value, or the scaling might have to be looked into.  These are the place I would start looking to track down the problem, though. -Les
