That's why BBE has this on all address pages...
Note: While the last "balance" is the accurate number of bitcoins available to this address, it is likely not the balance available to this person. Every time a transaction is sent, some bitcoins are usually sent back to yourself at a new address (not included in the Bitcoin UI), which makes the balance of a single address misleading. See the wiki for more info on transactions.
So the change addresses aren't included in the "Your Receiving Addresses" menu item in the client? How can I find out what my change addresses are?
that's correct, you can't see them in the GUI... you could list all your addresses and see their
balances received amounts by using the RPC command:
listreceivedbyaddress(0,true)
