I rarely use preview for anything but this time I double clicked a file from a CD that just happened to be a 500mb tif. Preview began launching, but now it is not responding, like its basically frozen. I right clicked the icon in the dock to force quit, nothing. I opened the Force Quit Applications window, highlighted Preview (which is red and says not responding) clicked force quit, nothing. So I decided to eject the CD which I can't because it says the disk is in use. I tried to shut my computer down which I also can't, because it says that Preview isn't shutting down. Please help, how can I quit the program or shut down my system so I can take the CD out? * Tried quitting the process via activity monitor... nothing.
