I don't think you understand what you are talking about. The ease of "attack" (what kind of attack? You don't say.) has nothing to do with re-using small numbers of addresses, which has objective negatives.

Deterministic wallets completely solve the problem of backups.

Are there any iPhone wallets that correctly return the change of a transaction into a newly generated address, much like Electrum does?

BitWallet does not do this.

As far as I know there is nothing you can do, except try to remember the password.

Change addresses should never be used by the user, only as change from another transaction, so there is no use in showing change addresses with no bitcoins in them.

Change addresses with a balance of zero should be hidden.

That one is, yes, though I did a regular "Send" transaction, not a custom one, so whether the source addresses are imported or not shouldn't matter to me. I would expect all change to go to a "Change" address - that is the whole point of them. It didn't even return the change to the imported address, just to one of my other regular addresses.

This seems like a bug to me.

No, it's not imported.

I recently made this transaction with Electrum 1.9.8:
https://blockchain.info/tx/7ba987f202323c302b7cc736436a1858579255b131e4f7332caced3a96d945ed

You'll notice that some change from the transaction went back to 1K2TZGCiP8F2sZHtZ73LtyMQJUygFxwUUH, which is also one of the source addresses.

Why is Electrum returning funds to the same address instead of to a change address?

"Use change addresses" is turned on in the Settings.

Awesome, thanks.

Is it possible to determinate the unspent balance of an arbitrary bitcoin address (not one from my wallet) from the Electrum console?

The OS X link still points to 1.9.4, though 1.9.5. can be downloaded if you manually change the URL to http://download.electrum.org/electrum-1.9.5.dmg

I have a bunch of pre-generated vanity addresses (addresses that start with a word, like 1DocumentnGL9WwyL4ZkLoHcKhtfm5zFDk) that I don't need.

Because they're pre-generated I can't sell them safely using split-key because, well, they already exist.

If I wanted to try to sell them, what would be the best way to do so and prove I'm not planning to steal the purchaser's coins? Is there some way they can be setup as a forwarding address, perhaps?

Alternatively, what else can I do with a bunch of vanity addresses?

IMHO, it made more sense to have those options in the menu bar. Mac users are not accustomed to routinely right-clicking things. The menu bar is the standard place to put things like that on the Mac.

Aha. Was it always like that? I'm sure I remember options being in the menu bar.

Apologies if I just remembered wrongly. (!)

Thanks for fixing the link.

A couple of issues with the Mac version:

The download link is wrong. The link points to http://download.electrum.org/electrum-v1.9.dmg but the actual correct link is http://download.electrum.org/electrum-1.9.dmg

Secondly, the menu bar in Lite mode seems to have vanished. There is no way to show the receive addresses in lite mode.

I restarted repeatedly, it did not help.

These transactions now show as confirmed. Still, the delays are concerning. I've moved my remaining coins to MultiBit until I can be sure the problem is fixed.

That is the server I'm using - please read my original post!

The last three transactions I made with Electrum are still showing "Unverified" after several days.

The transactions themselves have received many confirmations on the blockchain, such as this one:
https://blockchain.info/tx/1eed09277aa0d036791e5bbdb1dea5f9aad4376b63e1eba565a50b677e8d8cad

Is there anything I can do to get Electrum to "update"? I know there was that bug recently, but I'm connected to electrum.be which I thought was patched. I tried electrum.no-ip.org but got the same problem.

I'm running Electrum 1.8.1 on OS X 10.8.4. Any advice?

Is there any way in MultiBit of getting a breakdown of a wallet balance, so you can see exactly how many bitcoins are stored in each address in that wallet?

Please could I be given access to the "Electrum" forum.

I don't need unrestricted access, just the Electrum forum is enough. I've been using Electrum for weeks and can answer many of the questions being posted there, or rather I could if I had access.

Thanks.
