MS Internet Explorer trouble

I finished my website, but I’m having a hard time figuring out why it doesn’t work in Internet Explorer on PC. It works in every other browser on both Mac and Windows platform, but not Internet Explorer on PC. For my portfolio section, I’m using scotty’s excellent V3_with_thumbs (see: http://www.kirupa.com/forum/showthread.php?t=87388 ). When the page loads in Explorer, the thumbs won’t load, and the page is very buggy. Does anyone have any experience troubleshooting this kind of thing? I can’t figure out what I’m doing wrong and why it works so well in every other browser. I work in Tokyo, and most people here use the default Explorer browser option on their PC, so I need to make this work to show them my work. I greatly appreciate any help anyone can offer, thank you!
