Ok: I'm a new Mac user and I recently starting having a problem I can't figure out how to resolve. Suddenly large icons have started showing up on my desktop of applications I already have on the machine. For example, I use Firefox and the icon is down at the bottom of the screen, as it should be. However, there is also an icon that looks like a large hard drive with the firefox icon on it. When I double click, it displays the firefox icon and an arrow that is pointing to the applications folder. I would assume it's trying to tell me to drag the icon into the application folder. I have done that but still the large blue hard drive looking icon is still on my desktop. This same problem is also happening with a few other applications as well. I'm sure it's an easy fix, but I just can't seem to figure it out. Any help is much appreciated!
