Why does a PDF not open correctly in my copy of Adobe Acrobat Reader?
A small percentage of the PDF documents offered on the Novell OpenCourseWare Web site may be compatible only with newer versions of Adobe Acrobat Reader. If you would like to view such a file, we recommend downloading the latest version of the Acrobat Reader from the Adobe Web site at http://www.adobe.com/support/downloads/main.html.
