Some of the text is not displayed in the Web interface windows. You must ensure that the Display Font Size for your System is set to Small Fonts (96 dpi). If it is set to Large Fonts, the Web interface will not display correctly.

"URL not found" messages are displayed when the Contacts, Home Page, Library or Support icons in the Help View are clicked. Your management workstation cannot access the World Wide Web. Contact your network administrator.

The Customize Response page is not displayed when a Web site is blocked.

There is a default option in Microsoft Internet Explorer 4 and later versions that will cause a “friendly HTTP error message” to be displayed when a Web site is blocked, rather than the response page generated by the Webcache. You can turn this setting off by selecting Tools > Internet Options > Advanced and unchecking Show friendly HTTP error messages.

The Proxy Auto Configuration (PAC) file is ignored by the Web browser.

You must set the Web browser to read the PAC file for its settings; for more information, see “Proxy Auto Configuration (PAC) File Scripts” on page 50. In Netscape, you can enter a shortened PAC address such as webcache:8082 and Netscape successfully configures itself using the PAC file. In Internet Explorer, however, this address is not recognized and you are not warned that the PAC file is being ignored. You must include “http://” at the start of the URL i.e. http://webcache:8082.
