I followed instructions on the electrum site for creating an offline wallet, then using it's public key to "restore" a wallet on my online computer. I just tested the online (seedless) wallet to see what would happen if I sent bitcoin, however electrum never "queried for a location to save the transaction," it just sent the bitcoin.

What am I missing here? I noticed that the master public keys of my online and offline wallets are different, is this normal?

Is there a setting that I might have missed when restoring the online wallet?

Thank you.
