I received a runaway exception error then deleted everything but wallet.dat from the data directory and opened bitcoin-qt to redownload the blockchain. Initially my entire balance was unconfirmed, but as the blockchain downloaded the balance and unconfirmed amounts would adjust as past transaction became confirmed. However, after a while, the balance and unconfirmed figures wouldn’t change even as more transactions became confirmed. I am still downloading the blockchain. Is there anything to be concerned about? Will my entire balance show as confirmed once the entire blockchain is downloaded? Should I finish downloading the blockchain?
