I have a newish macbook pro running both osx and windows xp pro. In addition, I have a third FAT32 partition on my hard drive where I store all of my music files so that I can share them with both operating systems. The problem I am having is I will attempt to play a song and an error message telling me the file cannot be found pops up and then asks me if I would like to locate the original. If I select yes and then find the file, when I attempt to listen to that song in the other operating system I get the same error message. I don't understand what the problem is considering I'm not actually changing the location of the file and both itunes libraries are set to manage my music. FYI, I have the most recent version of itunes for both osx and windows.
