Why Can't I Connect? 1.10.3 发布，更新内容如下：
1. Changed the visible trace to be easier to read.
2. Changed the remembering of a server name to the drop down list from
when it is connected to when it's IP address is resolved.
3. Changed the default timeouts from 60 seconds to 20 seconds. This only effects new installs. Previous installs will still need to change the timeouts in the preferences dialog.
4. Switched the "Ports In Use" default port type to listening.
5. Fixed a bug in the "Script Save As" to include the script run time parameters.
