Duffy no one else has reported this and that part has not been touched in a while. Think you might be missing something in the install.

Getyler2 you have jquery installed on the home page with that slider. Mootools and jquery do not work together. There is a way to fix your problem if that homepage slider is the only thing using the jquery- move the jquery to includes/modules/pages/index. Then the jquery will only be included on the home page. There are some ifs in that though. May not work on your cart; may turn off other jquery features.

This is an old mod and if I were doing it today, I would use jquery and not mootools and probably avoid these problems. But I didn't write it in the first place.
