another instance has been reported.
in the mean time, do you still have that issue?

It could work.
I think it could be added to the existing 'exchange rates' plugin

just redownload electrum for android; I fixed that just now.

Version 2.4.2 was released today, with OSX and Windows binaries.
See https://electrum.org/#download

However, hardware wallets (trezor, ledger) are not supported in the current Windows binaries.
If you use a hardware wallet, please wait until we have better binaries.

Thank you for your feedback. We try to make a wallet that is easy to use for both basic and more advanced users.
For that reason, we do not provide all the functionality in the GUI.

This is the kind of thing for which I would use the command line.
I would be willing to such a functionality to the GUI, if it does not overload it.

There is one, but it is not visible: you have to type ! in the amount field.
(For the record, Electrum was the first wallet to provide this option)
Electrum will deduct the transaction fee from the total. (if you set the fee to zero, it will just write your total balance)
You can also combine the ! key with 'send from': select several addresses, click 'send from', and type !

I hope this also answers your first point.

This sentence lacks grammar. I guess you are referring to a bug in the Windows GUI, that should be fixed soon.
Anyway, next version will have an option to use dynamic fees suggested by the server.

I am not a Windows user, so I don't really know what Alt-tab does; I did not know it reopens the broadcast window on windows.
In any case, I fail to understand how you relate the apparition of a popup to your private keys being unencrypted.
You might become victim to all sorts of scams if you believe that the security of your private keys is reflected by the presence/absence of windows in your GUI. That's not how computers work.

This is done in order to protect users against their own stupidity.
See the FAQ for more details.

these are good points.

you should not use Windows if you are serious about security.

fixed in https://github.com/spesmilo/electrum/commit/6b8725679539a050d718cf7a8ace26607002fff8

you can restore a 2fa wallet from its seed.
make sure you properly check "two factor authentication" when restoring, as described here: https://electrum.orain.org/wiki/Two-factor_authentication

check the new tutorial: https://electrum.orain.org/wiki/How_to_accept_Bitcoin_on_a_website_using_Electrum

Indeed. We are currently experiencing problems with binaries, that's why 2.4 binaries are not available yet.

The Wordpress plugin was not created by me, but I guess they could use this new tool.

Electrum 2.4 can be used in to accept Bitcoin on a webserver, with signed payment requests.

I recently added this page to the documentation:
http://docs.electrum.org/en/latest/merchant.html

enjoy!

@OP, I would like to know what happened.

was it a change address?
if yes, why did you think that your wallet was empty?

if it's a change address, it is included in the balance shown by Electrum.

maybe you had the feeling that your wallet was empty, because of what was displayed in the 'addresses' tab?
if that's the case, it is something we definitely need to improve.

are most of your addresses used and empty?
I think an option to not subscribe to used addresses would make sense.

Again: YES. How many times will I need to repeat that?
Yes, you can recover your wallet from its seed, at any time, even if the service dies. It is fully deterministic.

Competing services may not have that feature, but Electrum does have it.
I would certainly not propose that service in Electrum if it was not the case.

The service is operated by TrustedCoin.
The fees paid by users are shared between Electrum Technologies and TrustedCoin.
The service was developed by both companies.

what the F*** do you mean by 'normally'? If you mean 'without a remote server', then you can create a multisig wallet with Electrum, and sign transactions with two devices; it will not cost you anything. It even works with android.

OTOH, if you want the convenience of someone else hosting and securing a cosigning key for you, then someone has to pay for the server operation, and for the people developing the service. I do not want to run that kind of service on VC money (like BitGo does), because I want Electrum to remain independent, and because it does not work in the long run (what do you do once you run out of VC money?)

Please stop spreading FUD! Bitcoins stored in a 2FA wallet can be fully recovered from the seed, and spent.

How do we achieve this?
Here is the trick: The public key of the cosigner service is not needed, because it is derived deterministically from the seed.

You can test it by yourself, it works.

many Electrum servers have a DoS-protection limit of 10000 addresses.

I suggest you archive your wallet, and create a new one.

If you cannot find any server and have issues sending your funds to the new wallet, you may import only the funded addresses in a temporary wallet.

Here is how you can see the list of funded addresses, in version 2.3:

same list with balance:

then get the private keys with that command:

switch to a different server.
I recently reboted bitcoind on ecdsa.net, in order to flush its memory pool.

and OP please rename this thread appropriately.

We recently discovered that the OpenAlias plugin, shipped in Electrum 2.0 to 2.3, does not correctly validate DNSSEC records.

A fixed version is in the works, and will be shipped in version 2.4. (ETA: a week)
In the meantime, please do not trust aliases verified by that plugin.

This traceback means that your database was corrupted.
There is a robot, 'electra', that detects servers with a corrupted DB, and kicks them from the irc channel.
Unfortunately this robot is temporarily broken (I will try to fix it this week), and it seems that a few servers have been running with db corruption without noticing it.
This reorg made the job that electra usually does
