I have noticed that with the latest iTunes (updated through the Apple update thing), that I now have a swoop noise every time I click the store or shopping cart icons on the left, and anything I click in the store. I had no idea where this mysterious noise was coming from at first, but I found it's coming from iTunes. It also occurs when I'm in the store page, and the first time I click any other icon on the left that's not under the store category. After that first time, it doesn't occur if I just click the icons that are not under the Store category, but once I click the store, the sound is back. Have any of you had the same "problem"? I've looked around in the settings and found nothing relating to a sound, and this is the first time that my iTunes outputs anything that isn't music. I am running Vista Home Premium x64.
