Glider full width problem

Hi, first of all very nice plugin. I really enjoy to work with it.
Now to my Problem, its bit strange because not even can solve it with my backups…

The full width slider is not anymore full width. It has just the width of my collumn. When i resize the browser it gets back to full width. So i estimate that its something with the processing order ot the javascript?!?

On my Backup few hours ago its still fine. I deactivated all Plugins witch iam working on but i still have the same Problem.
