A buzzing and clicking noise was coming from my computer. First reaction: "Oh shit, my hard drive is failing." Then I realized I had set up a cd to burn about 10 minutes ago and it had never finished. Essentially, iTunes had crashed while burning a cd and never told it to stop. I had to shut down my computer to fix it. I have problems with iTunes in windows all the time. Sometimes when an update comes out, it'll stop starting until I update. Once I updated it and it wouldn't start until it did one day at random. Anybody else have similar horror stories?

Edit: Oh yeah, changing my avatars, suggestions?
