I wanted to send 4 bitcoins to my smartphone. I had a contact with a label in my electrum. I searched the contact, only one label to see on the screen, and must have looked away shortly, i clicked the only address that had a label on the screen and sent since i believed when i used "send to" it has to be the correct address.
Unfortunately it didnt reach the target. I checked the transaction and did not find out what address i sent to. I thought maybe i had a virus that changed an address in clipboard but when i checked blockchain i sent a transaction to it a year ago. Luckily it was the address of a friend that had a label "Friend Test". So i could get the 4BTC back now.
I know its my fault too to not check more carefully though i didnt thought in that moment about the possibility that electrum could change the screen i see. So i used the address that was the only one with a label like the page was where i searched the address before.
I really would like to see Electrum mature here and have a more user friendly updating procedure. Its the first time it could have done harm now but it was work before too often enough. Writing labels... update... searching the address again, writing label again. Or when checking transactions to find anything. I have thousands of transactions and its extremely annoying to go through the list and... youre at the start again. Now try to find where you were and hope that it not updates before you can search a bit more.
I understand; I will try to fix this soon.
