This applications does absolutely nothing. It was created to make system Prefs / Button happy on my Treo. The Button allows you to define what application you want to run when you hit special hardware buttons. I wanted none to be assigned here for one of the buttons (used in other app), but the Palm forgot to foreseen that option and I had to choose the applications. So I created Dummy and feed Button prefs with it. And now we're both happy now ;) So whenever you have to configure some app to be invoked on some events, and you don't really want to do so. Unless you got other option, this dummy is for you .
