Hmm, everything is working here in C6P 6.0.3 How exciting. You don't mention how much RAM you have - that could be the culprit. I think I remember seeing somewhere that there are some memory management improvements for a C6 update. But even so, working with highly detailed meshes does require some decent RAM anyhow. Regarding the other question, weight painting is all that's available in Animation Mode. If you're going to do a still pose, you can export V4 as a .obj or .3ds and then reimport the figure into the scene (you'll have two v4's unless you delete the original) or simply open a new scene and then import the converted V4. (this is the safest method) P7 is a good product but not without it's own quirks. The workflow in Carrara is easier and faster when working with figures. I do use both depending on the assignment parameters.
