When I try to view a pdf document, the screen goes blank. Why?
Please be sure that you have Adobe Acrobat Reader (version 4.0 or higher) installed on your computer. This is necessary to view pages from the catalog. You can download a free version by visiting their site: www.adobe.com Also you should check your browser settings and ensure that session cookies, saved cookies, JavaScript and active script are enabled. Any of these can prevent you from viewing pdf documents.
