**From my understanding of it all.....V4.2 overwrites V4.1 in that she makes V4.1 become "injectable" so that in order to use your "old/previous" characters for V4.1, you need to inj ALL morphs. This is if you have a scene with V4.1 saved. She may not load back up looking right, but should once you do that. You can also load V4.2, then inject her ALL morphs (base and +++) and then click on the character you want and she'll do as she should. But you MUST inject all of her morphs before you click on the character you want to use.

A4 is an added morph to V4.2 and has nothing to do with A3. Your A3 is perfectly safe from her.

Hope that helps some.
