Okay, I my new 24" iMac, but I have one silly question. I download a file in "dmg" format and it puts it on my desktop. I then double click the icon to install the program. but then what do I do with the dmg icon of the program once it has been installed. I tried to drag the dmg icon to the trash can but when I do that it uninstalls the program altogether. what's up with that and how do I stop it from doing that? I just want to get rid of the dmg icon from my desktop but obviously I don't want to uninstall the program.
