The app runs fine on my X10... which is to say once I went through the first configuration I could launch the app manually by selecting it in the app drawer.
However , I can't get it to launch off any of the hardware keys using press, double-press, nor press-hold. I'm using ADW.Launcher, so that may have to do with it.
