To copy stuff to the device, drag items - songs, albums, artist names, etc. To remove them, you need to click the triangle next to the device icon, then select, say, Music and choose the items you want to delete, then press the Delete key. > > This seems the way iTunes performs regardless of whether the "Manually Manage..." option is checked or not. I've never seen iTunes sync with iPhone automatically, it always waits until I click on the "Sync" button at lower right corner of iTunes window. I've always left the "iTunes will automatically open when device is connected" unchecked, if that matters. > > This is why I asked, because I've never noticed a difference in operation between "Manually Manage..." checked or unchecked. You're talking about initiating the syncing process, not manually/automatically syncing music and video files. That's a different animal. iTunes does sync other content, especially with an iPhone. You can't sync apps, contacts, etc manually. So that Sync button matters. Kirk Author of: Take Control of Users & Accounts in Snow Leopard http://www.mcelhearn.com/tco.html
