This check box allows you to set whether or not a small Sloop Sail icon will be displayed on your screen when you start up your computer.
The startup icon can be useful for detecting whether or not Sloop was installed properly since if something goes wrong during initialization, the icon will have a red X through it.
However, some people don't like having long rows of extension and control panel icons displyed on their screen at startup. So if you're one of these folks, uncheck this box.
