It could well be that certain properties and applications in your browser are disabled--such as
JavaScript. If you are using:
Netscape click on EDIT in your menubar, select the "preferences" option, and
a tree menu will appear. You can
customize your browser through the modification of these settings. Click on the "advanced" option and
an checkbox-menu will appear. Make sure that "JavaScript" is enabled. If it is disabled add it to the list by
checkmarking it and then simply exit.
Internet Explorer click on VIEW in your menubar,
select "options," and another menu will appear. Select "security," click on the "Security" option, and make sure
that "JavaScript" is enabled. If it is disabled checkmark the "Enable Java programs" box and exit.
