IE6 rollover issue

I am having a problem on IE 6 with my rollovers. I am using java script to randomly display groups of images. There are 4 groups. The first 2 groups rollovers work ok, but not the other two which is really weird. I am controlling the rollovers using CSS hover. Knowing IE6 does not like the CSS hover class, I am also using the behavior class and csshover.htc code I found. I don’t think the csshover.htc is the issue. The rollovers work fine in IE7, FF2 and Safari(PC). I need some other IE6 users to look at the site and maybe tell me what is wrong.
