I'm unable to get the hover effects (effect #5) working on my install of IE9. First thought was I've broken the template, but none of the effects at:

work at all, producing a simple image switch rather than any fancy effects.

Oddly, the effects work fine in FF when switching user agents to any version of IE. I wonder if someone could check the above link in an actual IE install to see if whether it's just me.
