I am using Eclipse Juno. I was working in Java perspective and suddenly I minimized the console. I don't know where it went but I am unable to get it back. I even tried to get it from Windows>Show View>Console but I didn't get my console back.
It happened the same thing to me. Just click Window->Reset Perspective and everything will be back as it was when you installed eclipse. Sure you'll have to customize it back to how you like it, but at least you'll have the console back.
