Upgoing slider problem (IE/FF)

Upgoing slider problem (IE/FF)

On http://worldfashion.se you'll se what i'm trying to achieve on the three divs. In Firefox it works perfectly, but in IE i'm getting an annoying space at the bottom.

I'm changeing the css of the divs using .animate with queue set to false.

how do i fix this? do you have better approach to get the desired effect?

thanks
