Tony, I appreciate your help. Your suggestions have made the empeg behave closer to the way I want.
Also, in the midst of my complaining I don't think I made the point that I think the empeg is a very good product. I do feel like I'm fighting it sometimes, but that could be said of almost any product I own. I'm very picky. It happens that in the car I naturally have much less tolerance for a UI that is, at times, clumsy for my needs. But that doesn't change the fact that I think it's a very good product and I don't regret for a moment the money I spent.
