Full width slider : slides not centered.

Hello,

I am using your slider on my website, and I need to make it responsive. I have tried setting a 100% width instead of the 600px default one. The problem is that the slides are not centered anymore (check This). After playing around, I noticed that if I resize my browser, the slide centers itself, but on the page load it doesn’t.

I don’t really know how to fix this. Any idea ?
