I am receiving a low disk space warning. When I go to the configure screen to increase my disk size, there is a message that states the machine has to be shutdown to make the change. When I shut the machine down, I have no access to the configure option. I must be missing something very basic here right?

I saw an old thread which mentioned the need to run a program called Image Tools in the Parallels folder, but I have no such program. When searching the Parallels site, it was about as useful as the stereo instructions referred to in the movie Beetlejuice.
