PLUG-INS If you are fairly confident that your browser has Java installed, but something seems to not work properly, please check that you have your browser set up correctly. If you have a Netscape browser, go into the 'Option' menu, choose 'Network Preferences', and then 'Languages'. To enable Java and JavaScript, cross the check-boxes. If you have a Microsoft Explorer browser, go into the 'Edit' menu and choose 'Options', then 'Web Content'. In the 'Enhancements' section cross the check-box to enable Java. If you cannot check these boxes you may have chosen not to install Java when you installed your browser.
