It seems I can't connect to any servers with the windows build. I do remember an out of memory error popped up when I ran the .exe for the first time. Perhaps I can repeat that initial extracting by removing the files it extracts? Can I start clean somehow?

Sure, to start clean, just delete (or rename) the below directory:
  %appdata%\Electrum_SysFiles\0.60

Perhaps some files failed to extract properly the first time? 

If you do get that memory error again, please post a screenshot if possible.

Can't connect to any server or just to your server? What is the server name? Also, try both tcp and http and see if one works.

Ps: thanks for the pull request!

Sure, if you don't mind typing a few simple commands, Electrum can do just that, and is lightweight. Look up the exact syntax in the online documentation. I would have posted an example but am not home right now. Let me know if you need more help.

The Windows minimal build for release 0.60 is ready! (Download page in my signature.)

Changelist in 0.60 is in this post.

I also decided to leave in my little block count display mod
for now, as it makes troubleshooting some issues a little easier.
965  Bitcoin / Electrum / Re: Minimal Electrum builds for Windows XP & 7 on: June 23, 2012, 08:44:46 AM
I confirm the client is currently failing to create new wallets roughly 30% of the time due to the above reason.  I guess electrum.bitcoins.sk must be removed from the hard-coded list, and/or the (GUI) client must not try to connect to a server during wallet creation - unless I am missing something?

In the meantime, I will prepare and push out a build later today with the electrum.bitcoins.sk server entry removed.
966  Bitcoin / Electrum / Re: Minimal Electrum builds for Windows XP & 7 on: June 22, 2012, 05:04:20 PM
Ok did some more testing.

Via de console it can create the wallets just fine, no problem.

When starting the latest download by simply double clicking it I get a wallet created 50% of the time give or take. Other times it's just doing nothing. I can't rule out server problems at this point.

I've just done some testing, and I may have found something.
At the server selection dialog, make sure you don't connect to "electrum.bitcoins.sk" as
it is dead (as far as I can tell).
The problem is that it's currently among the 3 hardcoded server names in the client, which causes issues at wallet creation or restore if the client happens to choose that one. (The server selection logic in the console version is slightly different and doesn't have seem to have that problem)

Let me know if that solves your issue or not.

@ThomasV: you may want to have a look at this little issue Smiley

EDIT: also, why does wallet creation even bring up that server dialog, anyway? The process is completely local, isn't it?
967  Bitcoin / Electrum / Re: Minimal Electrum builds for Windows XP & 7 on: June 22, 2012, 04:34:45 PM
I can't seem to restore or create a new wallet using the latest version. I'm not sure if it's due to my incompetence, lack of patience (That damn generating addresses box stays open for 30 minutes) or something else.

Any advice?

Hi,

30 minutes is definitely not normal... Restoring a wallet can take between a few seconds and several minutes depending on your transaction history. For instance, my wallet (568 transactions currently) takes about 5 minutes to restore.

I would guess both issues (restoring and creating a new wallet) are related, so let's try to work on the easier one first: new wallet creation.
Can you try that from the console and let me know of any error messages?

Code:
electrum create

Just hit 'Enter' at all questions to accept the default values.
Generation should complete in less than 5 seconds normally.

@flatfly

I did some more digging why I couldn't change servers, and I think I figured it out. If I change the server using electrum the wallet updates as
Code:
'server': u'electrum.novit.ro:50001:t'
, where the (working) default was
Code:
'server': 'ecdsa.org:50001:t'
. If I make adjustments to the wallet by hand so that "u" is not appended everything works perfectly (I am able to connect to other servers like that just fine).



Really strange... I haven't had that kind of issue at all.
Just curious, does the wallet recovery procedure work for you, or does it also fail?

Nope, not working either.

Really? Could you try to do it from the command line and post any error messages?
This could help us find out what's going on.

Code:
electrum restore

edit: confirmed by another friend, but only for tcp

Really? Does he have the same version of Windows as you? Using the latest version of Electrum too?
970  Other / MultiBit / Re: MultiBit on: June 20, 2012, 12:57:54 PM
There is a new release of MultiBit at:

http://multibit.org


Version 0.4.0

Enhancements:
+  Introduction of protobuf format for new wallets
+  Upgrade to bitcoinj v0.5.1 library
+  Upgrade to XChange v1.01 library
+  Added Message window
+  Minor UI improvements to help browser

Release info
Scan of release checklist


Note: Protobuf wallets you create with MultiBit 0.4.0 are NOT readable in earlier versions of MultiBit

Next up will be a conversion utility to convert old wallets into the new format.

Nice release!
By the way, how much RAM is it recommended to have (on Windows, for instance)?

Just days ago, I was telling a friend that most banks actually have VERY poor security, and he didn't believe me...

Your friend is right.

Really? Do you know how many banks (especially in the US) still only use 8-character-max passwords and no 2-factor authentication for their online banking? Yes, in 2012...  And that's just to take ONE example.

Besides, you won't often get "proof" of a bank hack. That's not the kind of thing banks like to confirm/advertise.

Hard to say what the implications of this hack are, because not much information is available yet, but, if this is real, I imagine it's going to cost a lot to banks, both financially and in terms of reputation. Which could be good news for Bitcoin... Smiley

404 not found on that gui_qt.py link.

Sorry, you can try again now. Let me know if it works for you.
974  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - a new thin client on: June 18, 2012, 09:41:47 PM
Could you add an at-a-glance way to see the current block number -- perhaps in the lower right corner?

You mean, something like this? Smiley


I have made a little patch for it and am currently fine-tuning it.
The patch is ready. If some find it useful and want to test it out, just let me know and I will post it.
(It's NOT included in my releases at this time.)

EDIT: Added a little hyperlink to the BlockExplorer count, for a quick comparison.

PS: bear with me, I'm still a beginner with Python and Qt Smiley

Could you give me a patch or a diff, want to try to patch my OS X version Smiley


Sure! To try it out, just back up your copy of gui_qt.py and replace it with this one:
 http://dre.tx0.org/gui_qt.py  (file size should be 53791 bytes)

Hopefully it should be OK on a Mac too, let us know Smiley

Thanks, seems to work fine, I hope this gets added to master.



It's not as pretty as on Windows but it will have to do Smiley

Thanks for the feedback!
If ThomasV decides to merge it, it's just 4 lines of code.
975  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - a new thin client on: June 18, 2012, 09:20:49 PM
That's correct, the wallet is totally server-independent. You can connect to any server, or even create your own.   

What you are experiencing is a server problem - uncle-enzo has crashed, I believe.
In my experience, the most stable servers currently are ecdsa.org and electrum.novit.ro.

Thanks for the confirmation Smiley

There's something wrong with the server not importing transactions while running. I'm currently importing the backlog of transactions that it missed. If you follow the electrum server discussion thread, it isn't just uncle-enzo.info that's having this problem.

OK, thanks for the info. Hope you guys can sort it out quickly.

Does anyone else have problems with their clients not updating (on ecdsa.org server)?

Yes, ecdsa.org seems to be stuck at block 185096. I would suggest to use electrum.novit.ro in the meantime - it's been quite stable lately.

I just want to be sure I understand this but your wallet is not tied to a server somehow correct? When I connect to uncle-enzo.info my wallet balance stays on 0. This is not intended but probably a server problem?

Normal version: %appdata%/Electrum
Portable version: same folder as the executable
Thank you  Smiley

Had to go to c:\users\username\AppData\Local\Electrum

The %appdata% only showed me c:\users\username\AppData\Roaming\Electrum-P

I didn't know about the Local vs Roaming folders in Win7 (I use XP, mostly)... Thanks for your feedback.
