Frames and JavaScript
Illustation of frames This Web site uses the frames function of your browser. Frames allow Web pages to be viewed in one area of the browser while leaving other areas static. The site also employs JavaScript, a scripting language that adds functionality to the Web browser. (In this case the menu system and the concept circle illustrations use JavaScript)

Both the frames and JavaScript in this site are best viewed using Netscape Navigator version 3.0 or better. To download a free copy of the browser, go to the Netscape Download area.

Once you have the required browser version, be sure the JavaScript function is "turned on" by enabling it in the "Network Preferences, Languages" area of your Options menu.

Note: Java (a language separate from JavaScript) is not used in this Web site.

How to turn on JavaScript illutration

Active frame illustration In navigator 3.x, active frames have a black border around them.
In any browser, be sure you click once in a frame to activate it before you print, save material to disk, or browse deeper into that content.


Opening and Closing Windows
New window illustration In some instances a larger version of an image (2) is available and can be seen by clicking on the small image (1).

This opens a new window, which means you have two browser windows open at the same time (like a desktop with two documents open at the same time).

Close box Illustration When you are finished viewing the image in the new window, click the close box in the upper right corner, or select close from the file menu. Your original location will still be in the other browser window.


Turning Off Images
How to turn images off illustration Images take longer to load than plain text. If you would like to browse the site without images, un-check Auto Load Images under the Options at the top of your browser.
