If you use a Windows computer to manage your iPod library then chances are good that you've run into the frustrating condition where iTunes pretty much hangs, or freezes, your XP or Vista computer when you try to exit the iTunes program.
Search the web for "itunes hangs (or freezes) windows xp exit" and you'll plenty of folks looking for answers or work-arounds for it -- including on Apples support forums. You may also notice that these complaints go back for years and that there are zero ("zip", nada, none, nothing) responses of any kind from Apple. (Like Windows users aren't used to that from Apple; LOL.)
So, OK; here's the work around -- but please, do me a favor first. Please don't post this on other forums and blogs but instead please just link over to this page. I really will appreciate it very, very much.
