Electrum 2.8.3 Not Responding After Closing

[Lucius]

I download for first time Electrum BTC 2.8.3 and install without any problem.Then i import my private keys from MultiBit Classic using this info : https://bitcointalk.org/index.php?topic=1924340.0

After few minutes wallet is sync and I see my balance and transaction history,some transaction are not veryfied-they get veryfied later but when open wallet again I see some of them again are not veryfied,is that normal?

But main problem is that after I click on "Quit" wallet is not closing-just not responding and need to be close through TaskManager.The operating system is Windows 7 Enterprise and I use Electrum wallet for LTC&DASH,never have such problem.

Did the wallet fully sync and you saw the green light in the lower right corner of the window?

It is possible that by force closing Electrum, some of the synced data isn't properly being recorded which is why you are seeing them not verified once you re-open the wallet.

Do any of the imported addresses have a very large number of transactions? I've seem some stability issues with imported addresses that have a ton of transaction history. You might want to try creating a new wallet using a seed and transfer your funds to that wallet. The seed based wallets are recommended also due to the easy of backing up and restoring a seed rather than a bunch of individual private keys.

Yes,wallet is full sync and I see all my balance but some transaction not veryfied/green light is on-I have Electrum for LTC&DASH so it is not my first encounter with Electrum.

I imported some 20 private keys in Electrum,and some of address have larger number of transaction so this may causes problem I have.Maybe only solution is to send total amount in new wallet as you suggest.I have to admit I did not know for this problem in Electrum,hope they fix that in some new version-or maybe not.

Is there any other lightweight wallet which allow import of private keys from MultiBit Classic?

You should sweep your private keys instead of importing them:

It seems that this could be a better option because I get another surprise when I was try to send BTC from Electrum.Wallet is not responding and complete freezes,I've tried many times but always with the same outcome.So importing private keys in Electrum is not working for me,as kolloh say this wallet is not recommended for many private keys import, especially if imported addresses have a very large number of transactions like in my case.

Regarding sweep private keys in Electrum,total amount of coins will be send to one Electrum address,this means not send through blockchain,is that correct?After that I can still use my old address/private keys(need some of them) in other wallets and then send coins to Electrum wallet?

No, sweeping creates a transaction on the blockchain. This is the only way to get coins from one address/key to another.

You can continue to use those private keys/addresses if you want/need, but it isn't advised as they have now been "exposed"... especially if you entered them into a copy of Electrum on an online computer. If you created the sweep transaction on an offline PC and offline Electrum then it isn't as likely they will have been compromised, but still not advisable to continue using those addresses.
