On courses where jmol has been used, when the course is accessed using a Windows 7 machine and IE, the molecular model is displayed fine, but below the model in bright yellow is the following error message:

You do not have Java applets enabled in your web browser, or your browser is blocking this applet. Check the warning message from your browser and/or enable Java applets in
your web browser preferences, or install the Java Runtime Environment from java.com: Java + You

Obviously we have java installed and applets have been enabled, otherwise the model wouldn't display. This does not occur on XP machines, just Windows 7. Any ideas on how to resolve this much appreciated, as we are ditching XP in favour of W7 - a bad move in my opinion, but that's another story .

With Firefox, the molecule displays just fine, but there is a message saying

Jmol script terminated

Thanks!
