Make it work in IE 6!

I don't have access to Opera/IE 7 right now, but I am 99.9% sure this works in Firefox, IE7, and Opera. BUT NOT IE 6

I've tried a number of things, but just nothing works. It seems to be behind or hidden, or something because if you for example click star 3, move your mouse around, and return to star 3... there's no change (which would be the effect in FireFox, except the red stars would be visible)

Somebody help me not fry my brain and try to help me find out how to make the red stars "stay" when selected in IE 6.

Thanks to all in advance
