移除「ThinkPad FullScreen Magnifier」的軟體，這個Fn+Space鍵就沒有作用了。

MS SQL Server 不能連線

Network Error IOException: Connection refused: connect
or
Network error IOException: Connection timed out: connect

Causes:

• The hostname or port number in the config.ini file is incorrect.
• A Firewall is blocking the SQL Server port.
• Your version of SQL Server 2000 is too old to support the way Coretalk connects to database.
• The SQL Server service is not started.

Solutions:

• Double check to make sure that the hostname and port number is correct and change it if necessary.
• Open the TCP/IP port for the port number specified in the config.ini file. You would have to first find out what firewall software the client uses and then add an exception to it’s rules for that specific port. There are too many free and commercial firewall systems to list instructions for all of them.
• This is very unlikely to happen. It will only happen if you install on an existing instance of SQL Server 2000 that has not been updated to SP4. If you can’t connect and everything else seems correct, make sure that it is SP4. If not, download the SP4 update from the Microsoft website and install that first.
• Start the SQL Server service. You should also go into the service properties and make sure that the startup properties is set so that the service starts automatically.
