There is a problem when running Auto Thickbox Plus in IE. The popup position is not correct, it partly outside the browser windows. If I select "Use WordPress built-in thickbox.js/css", the popup position is correct, but a lot of the excellent functionality disappears and other problems occur.
Example page: http://www.trolling.com/garmin-yamaha/
If you open this page in IE, you will see the problem. All other browser, including iPad, works fine.
Using iFeature Pro theme.
