I have an address that received funds but doesn't show in my Address book, what's going on?

Anyone had this problem before?

The issue was there with 0.3.24 and I upgraded to 0.4.0 and the problem still exists.

Well, the most usual reason is that the client keeps a pool of addresses for sending "change" to when you send a transaction.  You can receive coins at any of those addresses, but they don't get put into your address book because most people don't care about the nitty-gritty details of how everything is getting shifted around when they send coins somewhere.  Depending on your client, you may be able to add them to your address book if you wish, but it's generally not worth worrying about.
