Is there a way to save the download queue in iTunes ? I had to reboot my Macbook, and to my surpise, the queue was empty when I restarted iTunes. Is this behaviour intended ?
It appears that this problem was related to the fact that my installation was not a clean install but an upgrade. It was OS X 10.7 upgraded to OS X 10.8. I did a fresh install, and now everything is back to normal; the queue is correctly saved and restored across sessions.
