I'll bet you changed your e-mail preferences to disable Java. Many sites use Java for some of their information: under the Advanced tab choose Enable Java and Enable Java Script (Netscape Settings). For MS Outlook the settings are under Tools/Options/Security Settings/Custom Level/Enable Java.

I learned the hard way about Java. When turned off, sites would open but some of the functions would be missing (like things that used to work on the IGI site). The disturbing thing is, if (like your experience) I hadn't used the site before with Java enabled, I never would have known anything was missing.
