A really dumb question after my first program download on my new PBook. I downloaded Comic Life, a program on the Apple site to play with. I dragged the file to my applications folder as stated. It left me with what looks like the picture of a CD drive with Comic Life written underneath on my desktop. I also have a file named comiclife.dmg on the desktop. Do I need to leave both files there? It seems like the desktop will get really cluttered if you have to leave all of these misc. files on it.
