RokSprocket Module (Strips) not resizing

Hi. I'm using the Expert template and also using RokSprocket Module (Strips) on Front page, same as Expert Demo (Slideshow). For an unknown reason, the text box that goes along with the image doesn't resize at the right ratio. Is there a fix for that or is it possible to have a configuration that would allow perfect resizing of this module ?
My development link is: complexe6.justlink.info/index.php
It's the same for the Expert demo site.
Thanks for letting me know.

I found this code on another topic, it helps the issue. Anything else to suggest ?
@media (max-width: 400px) {
.sprocket-features-content {display:none}
}
