basket going in the bad direction on internet explorer

[kia]

I'm using PrestaShop™ 1.5.1.0

on the default template when you clik on a product, there is a js "animation", the product is going to the basket who is on the right of the page.

but on ie the animation is going on the left of the page although the basket is on the right of the page.

does anyone having the same problem ?

thanks for your help
