I often run actions that have modal control for certain steps turned on, in particular, when I want to give a layer a custom name. Prior to CS6, I'd run my action, the window would open allowing me to rename my layer, and then it finishes my action. However, in CS6, it seems to ignore the modal control button selected, puts in whatever the default info is and continues on. This hoses quite a few of my actions that I've been using for years.
