Also when reporting bugs regarding the Electrum wallet please note the time and date as it will help us dig through the logs to discover the root of the bug. We've been working hard on this for a bit so we appreciate everyones feedback. Just keep in mind that this is a beta and there likely to be bugs so don't send all your coins into the electrum wallet.
Also keep in mind that the Electrum wallet is a "light-weight" wallet not a full node. This means that the wallet relies on a daemon/full node for all it's information, it does not verify blocks/headers as thoroughly as the full node.
That being said it's a lot faster than the desktop full node and generally a pleasure to work with!
Happy testing!
