Slider not working in IE9

Hi there, first Id like to say I'm impressed with the theme. Although there seems to be a problem with the slider I have made in IE9 that I cant figure out, in chrome and firefox it works fine. The only customization I have done is in the form of a little CSS code in the required editing box, just some color changes to the background so far. Please help.
