Imported an address into electrum, but the balance of the address shows up as zero.

Checked the address on http://blockexplorer.com and it's not zero.

The address was imported from bitcoinqt when the blockchain is out of date and the transactions were never attributed to the address.

Nothing was sent from the address.

How would you refresh the transaction history for the imported address in electrum, so it becomes spendable again?

Thanks

EDIT: The problem has been solved - see workaround below

A workaround for this is to send a small amount of bitcoins to the the imported address

This was done by watching an ad at www.bitvisitor.com.

Once payment was confirmed in the blockchain, Electrum refreshed the balance and the transaction history.

The imported address balance is now spendable :)
