You can put a button over the icon that will open the IC window when you press on it, but here's the downside: the icon bank for the original start menu buttons are on a template. The data for these icons are streamed to the client from the server. As far as I know, there's no way to include a custom icon into that set. As such you would have a working button, but you wouldn't have the pressed button effect like you get when you press on the other icons. That's why I just made the icon for looks. It minimizes the file size, and eliminates perfomance issues that may arise. Theoretically, I suppose it could be possible to switch images as the button is pressed and released, but that goes beyond my knowledge at the moment. One of the other Authors would have to give you a more detailed explanation as to why it can or can't be done
