You need to add a background-color: #fff to the CSS for the body tag: otherwise, the user's default background color makes your design look less than optimal. Whenever you define colors, you should make sure to define a background-color (or make sure it's cascading correctly).

Well, unless the method of programming the Pronto has changed within the past couple of years, I think the Harmony remotes have a lot more going for them: ease of programming being the first. With the Harmony, you don't NEED a customer installer. Or to fiddle with the remote for hours. I gave up on my Pronto after about 3 months.

Does Pronto now has a way to save state in their remotes (which I would hope it does by now)? That is, to know what's on and off? That's another reason why I like the Harmony.
