As an application, Eclipse operates in its own memory space, keeping it from interfering with other operations of the system. If you need the memory Eclipse is using, you can always quit Eclipse as you would any other application.
Extension based screen savers can conflict with the operation of the system, causing unwanted crashes and delays in your work. Eclipse provides the benefits of extension based screen savers, while avoiding the problems they can cause.
When you run Eclipse for the first time, a document called “Eclipse Startup” is created in your Startup Items folder. This document is opened at startup time, causing Eclipse to launch automatically.
 
With Eclipse running, you’ll notice it is listed under your Application menu (see above). Eclipse places itself at the bottom of the menu list, out of your way.
 
Fat Binary
As a fat binary, Eclipse contains code for both 68K machines and the more recent PowerPC machines. Eclipse is smart enough to know on which machine it has been installed and loads the appropriate code when launched.
Being PowerPC native, Eclipse’s performance is outstanding on PowerPC based machines. Switching to and from emulation mode is eliminated, keeping your machine moving as fast as it can.
Eclipse also uses very little processor time to do its job. Even when the screen is dimmed, background processes continue as normal.
Ease of Use
Eclipse 3.0.0 is simple to use and has many options for customization. You can configure Eclipse to do several things when dimmed: display a collection of graphics, play QuickTime movies, display the date and time, or simply dim the screen to a specified brightness.
Eclipse is configured from the Preferences dialog box. To show the Preferences dialog box, you need to have Eclipse in the foreground. Then choose “Preferences...” from the File menu.
For a detailed description of the Preferences dialog box, see Chapters 5 through 8 in this manual or click on the “Go To” icon below.
