Note: Many features on the IST website require javascript. You can enable this via your browser's preference settings. FF: Tools » Options » Content (tab) » click Enable Javascript. IE: click on top warning bar to enable running scripts » Allow Blocked Content » chose Yes in the alert box that pops up. In addition, browser plugins such as NoScript for Firefox can also give rise to problems unless this site and it's scripts are allowed. Newer versions of IE may also initially block scrips from running, you should allow Scripts and ActiveX controls in this instance.
