Auto Refresh Credentials

Key Auto Refresh Credentials in ExCfgLvFdYF refers to a boolean that determines how often the credentials required for authorized web service requests to Yahoo should be updated.
Set to TRUE to update the credentials each time a request is sent.
Set to FALSE to update the credentials only once when Excel starts and thereafter only manually if and when the user decides so.
The default setting is FALSE because the credentials update incurs a small time delay that might not be necessary if the previous credentials are valid.
