This problem started after I did a reinstall of iTunes to resolve an unrelated issue. When I connect my 3G iPod Touch to my MBP, iTunes no longer launches like it use to. I have "Open iTunes when this iPod is connected" checked in the Summary page for the iPod. One difference I noticed before and after the iTunes reinstall though is that no longer is there an item called "iTunes helper" in my System Preferences/Accounts/Login Items list. It use to be there before the reinstall. I wonder if it's related to this issue. Thank you for any ideas. Enjoy your weekend folks.
