When you click on the QUIT button or come to the end of a module you will get a screen which will indicate you are finished and give you a chance to make several choices. Many modules have an EXIT choice that will end the CD-ROM. You can also quit the CD-ROM at any time by pressing and holding down the Alt key and then pressing F4.
If you click on CD MENU button, you will leave the module and go back to the main menu screen. If you click on QUIT from the main menu, the CD will automatically end and return you to the folder on your desktop.
