I'm not sure I understand. Which spell do you want to cast on the move? Or are you saying when you move, the camera resets to the default (rear) view?

If your problem is that the camera views don't match on both toons at the same time , this is not something that any multiboxing software can fix. ISBoxer can pan windows with the mouse at the same time but if you don't have them facing the same direction at the start, they will be out-of-sync and stay out of sync. This is normal and one of the things you have to learn to compensate for while multiboxing.

Does that help?
