I've had my mac for a couple of months now and I'm totally in love, however I have a couple of niggles I'd like to sort.

1. In iTunes, the date added is 12/09/2008, for all songs, even those I added this morning. The date in my menu bar is correct and I can't seem to find the setting to change in iTunes - any suggestions on how to fix this?

2. A couple of times my dock as disappeared. I do not have it set to hide automatically, and checking and unchecking this option does not bring it back. Have I done some random key stroke to make it hide? If so, how do I bring it back without restarting my comp?

Thanks for your help.
